Sorry, I didn't notice! My bad.
It was with the MacBook Faux (the 13” MBP that shares its internal with the MBA). Anyone with high performance commuting needs should definitely be looking at the 14 or 16 inch MBP instead of the Air or the legacy 13” MBP.
 
I’ll just add an anecdote from my own personal experience.

I have an M1 Air, 16GB/512GB. I am able to run Parallels with Windows 11 ARM using Visual Studio 2022 doing .net 6 based development and my machine never gets hot nor slows down that I can tell.

I will usually have 4 tabs open in macOS Safari and 4 or 5 in Microsoft Edge Chromium in Windows, plus Visual Studio doing builds, etc.

When I’m doing 20 minute Visual Studio builds in the Windows VM, while browsing and listening to music in macOS, my M1 Air barely gets warm to the touch and I’ve never experienced any perceptible slowdown.

That’s what’s achievable with my M1 Air. It’s head and shoulders faster and cooler (and 100% silent) than my 2018 MacBook “Pro”. The same work on that machine literally made it too hot to hold. I had to get a lap stand, and the screaming fan made it unpleasant to work with, not to mention sucking dust into the chassis and onto components. Oh, and builds were dog slow.

I’ve read a lot about how the Air shouldn’t be used for “Pro” workloads. That’s subjective. It should be used for whatever purpose it is fit for. The reviews that have contrasted the M1 and M2 Air performance were very helpful. Objectively, the M2 throttles sooner than the M1 and in some cases workloads take longer than on the M1 due to that. Valuable information to have for many of us “Pros” who “want it all” - cool, fast and silent - as the M1 Air delivered.

If your mom (not to pick on moms, but this is a frequently quoted demographic) won’t be running the Pro workloads as shown in some reviewers’ videos, then you’re likely correct that the base model would suit them fine. To each their own. At least we have the benchmark and workload testing results and can use them to inform our purchasing decisions. 😊
You use case would certainly be quite feasible in the M2 MBA. What most of the YouTube videos are doing is much more intensive processing that just a VS build. They are doing FCP renderings with lots of plugins on 8K video while doing other tasks. Basically they are generating their YouTube videos. When the MBA slows down to keep cool, that is declared to be “terrible throttling” and a “massive failure”. How often do you do that kind of work?
 
This is the benchmark problem in a nutshell. This doesn’t jump out to anyone as weird? It was weird enough to me that I actually watched the video.



Long story short: The M2 MBP 256GB did the copy in 32 seconds versus the 512GB in 23 seconds, MaxTech is the hackiest of hacks, they are everything that's wrong with YouTube culture, they're being financially rewarded for spewing nonsense, and they can't even number their graphs and charts correctly, let alone calculate the data right.



Long story long, and remember the debate here isn't about whether the 256GB drive is at all slower (it is, it has to be), or why, or Apple's ethics, it's whether benchmarks are being used appropriately and meaningfully in the discussion:

[0:24] "Does the SSD speed matter when there are no other variables whatsoever?"
[0:50] "I am sick of making videos on this topic and this will be the last one."
[1:21] "I believe it is our job as reviewers to do high quality, detailed, real world testing."
[1:40] "Now we don't like any drama, any beef..."

[3:00] "At which point people are saying this is all true, but your titles are just going over the top. [...] I dunno, maybe we're just covering these topics in too much detail?"

So no drama, except yes drama, everyone on YouTube loves drama, maybe people don't like us because we're too detailed...


Blue MBP is the M2 256GB, Red is the M2 512GB.

On to the Blackmagic results:

View attachment 2031996

Note, that the purpose of this benchmark is to determine if your drive is sufficient to read and or write video streams. Both drives show all green checkmarks except if you are streaming 12k resolution at 60fps. So if the fact there's insufficient space for 3 min of footage wasn't enough of a hint, it's worth knowing that you probably shouldn't use a base model MacBook Air with a 256GB disk for your 12k ProRes project.

The only thing this benchmark does is open a file and write to it procedurally (no work is being done to create the content) and then read that file back into a void (no work is being done with the data read)-- just a pure push disembodied data through the pipe test. Real world stuff.

Just to mark these numbers down: the 512GB drive is 85% faster on reads and 70% faster on writes compared to the 256GB.

Ok, now the test that brought me here. The external 42.51GB file copy, which we're told is completely normal for someone with a 256GB Air (?) and that shows the 512GB destroy the 256GB.

512GB M2 MBP: 0:23
256GB M2 MBP: 2:17

OMG!!!111 That's crazy! Why would anyone buy that?
The difference, we're told, is all to do with the SLC cache. The 256GB slows down because it fills its cache.

After that, it "is actually writing at about 200MB/s"
View attachment 2032018

Now I don't know how they round, but doesn't that look closer to 300MB/s than 200? I mean, if you were going to round, wouldn't you round to 300?

We're told most reviewers don't talk about the cache, while he shows the read rate over time for a 1TB Samsung 980 Pro-- so I guess he's not going to talk about cache either. If it was really his job to provide us with high quality detail, wouldn't he show the read rate over time of the Apple SSD rather than some random Samsung?

Does Apple really use an SLC cache? How big is it? Wouldn't the 512GB also have a cache? Wouldn't you expect it to be twice as big at most? Tell us about the 512GB cache!

Wait... This looks a bit dicey, doesn't it?

View attachment 2032017

How much space is left?

View attachment 2032020

3 freaking GB remaining on the boot drive and the copy still isn't complete!

He's writing a 40+GB file right up to the last 0.8% of the boot drive capacity.

Does that seem like a speed test with "no other variables whatsoever"? Does that seem like a drive speed test that any sane person would do? Does it seem even close to real world? Was part of that 2+ minute copy spent clicking away incessant "your startup disk is almost full" messages?

View attachment 2032021

Isn't that the type of detail someone should disclose?

[4:30] "We're not maxing it out because our external drive is slower"

Wait, so you're using an external drive to test an internal drive, but your external drive can't even keep up? How fast is it? Shouldn't you have started with a Blackmagic test on that external drive so we know the test you're doing is even relevant? Let me guess (I don't have to guess, I know): you're going to mention that a few times to imply without proving it that the results you're presenting aren't even as spectacular as they could be. No drama, just high quality detail. Maybe so much detail that people are complaining...

He points out that some annoying people are sure to point out that the M2 still transfers faster than the M1:
View attachment 2032027

"But there's a big caveat: you have to have your hard drives filled similarly for it to be accurate".

That's a caveat? I thought that's what "no variables" meant...

[5:20] "This one wasn't filled up all the way."

Do you believe the cajones on this guy? He finishes a transfer with less than 1% free and claims it's not full. But that's realistic, we're told. If you're "getting along with a base model" that 98GB of documents is less than one video project, or if you go out and do a photoshoot with RAW files, the kinds of things the base model is meant for, then it's going to fill fast.

58GB of apps, but "a lot of these came with it", except for the ones that didn't because it looks like all of MacOS requires just 26GB for a clean install.

But he obeyed his caveat, right? He did his test with the hard drives filled similarly?

Not a chance:
View attachment 2032030

Plenty of space on that 512GB machine.

Ok, so what if we got really picky and insisted that he delete the PC test folder from Documents and try the transfer again?

View attachment 2032033

So the actual benchmark comparison is:
512GB M2 MBP: 0:23

256GB M2 MBP: 0:32

Which I will bold and italicize because the video makes a strong effort to hide that fact.

For example, the full screen graphic shown when he announces the comparison:
View attachment 2032034

Wait, what? Talk about staying on message! Oh, and nobody forget the external drive sucks!

But, we're told, this is why some people falsely claim the transfers are quick-- because people are doing copies when they still have space. If you fill the drive, let's make sure we show the bogus number again, this time with an arrow for emphasis:
View attachment 2032035

If you don't want the 2:17 time, "make sure at least half of it is free [...] which is a major bummer"? No drama there! You can only use half your drive if you want it to perform!

Now by this point we'd almost forget that the whole reason we were told the 256GB machine was slower was because of the SLC cache being too small and the 512GB having a bigger one. But delete 100GB of files and free up more than 47GB of space for your 45GB transfer and suddenly it's not a cache problem anymore? Hmmm... I'm starting to wonder if this guy understands how technology works...

Turns out the 512GB does slow down eventually when you need to make it look bad against a 16" MBP, "to about 350 or so":
View attachment 2032042
which jumps around a bit, but I find it humorous they draw the arrow when it says 304 and call it 350 but on the other drive draw the arrow when it says 283 and call it 200. And now they're testing the 512GB with a 1TB external drive and less free space on the local drive and are now transferring a folder of files for some reason which is always slower, but at least they're testing with no variables whatsoever.

While the 256GB version we're again told slows down into the "200MB/s range":
View attachment 2032040

Which I suppose would be technically true even if it were 299, but still seems egregious to me.


Now he "gets" that the 128GB might not be available, but still refers to people point that out as "Apple apologists". No beef.

"But take a look a this!" as he brings us to Apple's supplier database Amazon: There's a random SSD there we can talk about for $21. "It's not the price point that's getting them in supply chain"? While that's almost certainly an accidentally true if grammatically odd statement, finding a random drive on Amazon is not the Apple supply chain.

[7:55] "And this isn't a sucky one, this is faster than what Apple is using."

No it is not. It's SATA III. If he'd read the reviews below he'd find that it maxes out with a read speed of about 450MB/s, not 1500MB/s and certainly not 2700MB/s. Even two of those in a RAID aren't faster than what Apple is using.

View attachment 2032157

Even the seller says it tops out at 500MB/s

View attachment 2032159

Perhaps it's worth a reminder here that the point he's making is about what part Apple should put here:
View attachment 2032160

Maybe that's why he leaves Amazon to bring us to the other well known Apple tier one supplier ChinaFlashMarket (??) to show "the market price for one of these 256 gig TLC chips". He doesn't reveal any technical data for this particular chip except exactly one thing, the capacity.

View attachment 2032199
View attachment 2032200

Yeah, that's right, the only technical detail given is that the part he's referring to as "one of these 256 gig TLC chips" is a 256 gigabit part, not a 256 gigabyte part.

Is anyone still going to argue that MaxTech knows anything about technology, let alone operations and supply chain management?


But we're not done here. Now it's time to run Lightroom where he shows the performance with virtual memory with swap. Note the SSD capacity shown in the menubar for the 256GB model:
View attachment 2032206

It is still using a completely full drive, and now thrashing whatever small remaining drive space there is between write/erase cycles in the SSD. He doesn't show the available drive space here, but that bar looks a lot like it did when there was 3GB free
View attachment 2032020
and here he's using almost 4GB of swap space:
View attachment 2032205
This is the absolute worst case scenario for an SSD. Unlike RAM or even an HDD, a flash block needs to be erased before being rewritten and erasing is a much, much slower exercise than reading or writing. Usually this is solved by always writing to unused portions of the drive while the system erases pages in the background in a batch, but with no free space there's nowhere to write while erasing.

Meanwhile the 512GB model:
View attachment 2032207

But of course he claims "right now the only thing different is the SSDs, everything else is identical." which is embarrassingly false.

The results of exporting 50x 42MP images?

512GB M2 MBP: 1:45
256GB M2 MBP: 2:00

Which he points out "is a performance difference of 15%!"

He says it like that's proof how bad the SSD is, but remember the raw SSD write performance way up at the Blackmagic test showed the 512GB was 70% faster.

So, 100% more chips leads to a raw performance difference of 70% and a real world performance difference of 15% when pushing 2.5GB of data to a drive that appears nearly full while also swapping. That sounds like the real world performance is better than the benchmark. But that's not the story being told by MaxTech because it doesn't fit the narrative.

Then there's 45 seconds of drama about how disappointing it is that the export took 15 seconds longer.

Then he starts opening 10 browser tabs in Chrome (not Safari) to show multitasking performance. This pushes swap up toward 6GB, so we know the swap is active. No ad blockers, so both machines are running different ads in their browsers.

View attachment 2032220View attachment 2032221


Same story. Running the 256GB at the edge of capacity.

Of course even the 512GB took twice as long in this scenario, not that the chart they published makes any sense:
View attachment 2032242
Yay for high quality details! (That lower bar should be labeled 4:20 and that's a number not a comment on the presenters state of mind)

His explanation for why even the 512GB is slower? The M2 needs more ram than the M1. Wut?! Same OS, same instruction set, same workload, but the M2 for some reason needs more RAM? And what does this have to do with the SSD?

In this test, unsurprisingly given the drive architecture, available space, additional need for swap, and uncontrolled variables in the testing the 256GB takes 80% longer (7:43). That difference is, for some reason, not attributed to needing more RAM, but entirely to the SSD.

And, of course, that wasn't wasted time, because he's multitasking and doing other work while the export is happening because that's what multitasking means.

And I can't even make sense of the next set of comments about some test with the M1 MBP-- something about doubling the RAM, more tabs, some other apps open (ie. no variable whatsoever) giving these results that I can't interpret:
View attachment 2032247

It's at 12:30 in the video if anyone else wants to try to make sense of it (leave your comments below!).

Then there's some weird sidebar about how their audience is really into tech and is buying 3x as many base model Airs, so imagine how sad it is that people who don't know anything about tech are also buying the same hardware that power users are perfectly happy with.

Now a FinalCut export while multitasking:
View attachment 2032268View attachment 2032269

What's interesting here is that not only is the SSD near capacity on the 256GB again, we're used to that now, but the 256GB has consistently and significantly higher CPU and GPU utilization throughout the portions of the test we can see. How does one explain that if the export is being bottlenecked by SSD accesses for both export and swap? Doesn't that warrant an explanation and ideally an isolation of that variable?

The 256GB is again slower, no surprise, but he explains that's with "nothing else open", which is straight up wrong because he had a bunch of Chrome tabs open and was playing 4k 60fps YouTube content.

Then what I think is a great comment to close with: "I don't know what would have happened if I had 4 pro apps open and 25 tabs instead".

Yeah, if only there was a way for a reviewer focused on high quality, detailed results to know that... 🤔

His conclusion after trying to run production workflows through a base model Air? It doesn't deserve to exist, and it's only there to get people to upgrade to a 14" pro.


The stated point of the video wasn't to demonstrate that a 256GB SSD 99% full will slow down, it was to, and I quote:
View attachment 2032280
with, ahem, no drama or beef.

The testing here is so flawed and wrapped in hype, to be useless even as an indication of how this will perform in the real world. Any result contrary to the message is quickly buried. It's just a stream of consciousness from someone who fancies themself a pundit.

So can we please all agree that whatever people think about benchmarks, sites claiming to use them like MaxTech are a complete joke? They don't know what they're talking about, they don't know how to do proper testing, they have an agenda behind their data, they're extrapolating beyond what their data can possibly support and it's feeding junk science to a bunch of people who then go into the world and preach it like gospel?

Somebody else will have to tell me if this video from July 1 was the last video they made about SSD speeds as promised, because I refuse to click on another MaxTech video to check.

Brought a tear to my eye. That wasn't a post it was a rollercoaster ride of a short story.

But in all seriousness that's some good work. I didn't realise he was testing on an SSD that was nearly full capacity.

Honestly I think Richie is an alien.

Has anyone notice how the way he speaks is just a little 'off'? Like his choice of words, tone, where he pauses, just everything is a bit off.

Definitely some extraterrestrial sh*t going on there.
Yes, his voice cracks constantly and he speaks like he’s out of breath and trying to get out the last word of every sentence. Doesn’t really bother me but it’s real.

I still watch quite a few of his videos in the background if I’m just killing some time.

I look at this “argument,” full of silly characterizations of René and Apple — and the people who are the other way, and frankly, I wonder how politics and all kinds of things on the internet have become meaningless. “Im right and you’re wrong, and if I disagree with you you’re crooked. It’s pretty clear what’s happening now, once that we have seen the progression of the M! to the M! Pro and Ultra, that the Ultras don’t change the clock speed, do the same things at the same speed as the others, but the number of cores allow you to have many more of the same kinds of calculation to exist in each added core. A very useful improvement, especially people who do pro stuff. In the end, it can transform a huge AppleProRes to an mp4 at the same speed as the chip gives you, but now you can do more of them simultaneously. The M2 is fast enough, and efficient enough, so that you can have an entry computer that won’t heat up very much. It works terrific if you’re an average user. It begins to slow down to cool down after around 5 minutes. If you don’t need the continuous speed and coolness. buy the cheaper one. If you’re making serious editing and you want to deliver something more, quicker, use the more expensive option.

I'm not sure what everyone's problem is. Rene has never been the deepest reviewer - he's just a guy from next door, talking about apple products from the perspective of someone who doesn't know a lot about technology
and isn't enough of a nerd to learn it. I think, that's useful for many people - and the other ones already know better anyway.

Perhaps it's worth a reminder here that the point he's making is about what part Apple should put here:
View attachment 2032160

Maybe that's why he leaves Amazon to bring us to the other well known Apple tier one supplier ChinaFlashMarket (??) to show "the market price for one of these 256 gig TLC chips". He doesn't reveal any technical data for this particular chip except exactly one thing, the capacity.

Yeah, that's right, the only technical detail given is that the part he's referring to as "one of these 256 gig TLC chips" is a 256 gigabit part, not a 256 gigabyte part.

Is anyone still going to argue that MaxTech knows anything about technology, let alone operations and supply chain management?


But we're not done here. Now it's time to run Lightroom where he shows the performance with virtual memory with swap. Note the SSD capacity shown in the menubar for the 256GB model:
View attachment 2032206

It is still using a completely full drive, and now thrashing whatever small remaining drive space there is between write/erase cycles in the SSD. He doesn't show the available drive space here, but that bar looks a lot like it did when there was 3GB free
View attachment 2032020
and here he's using almost 4GB of swap space:

This is the absolute worst case scenario for an SSD. Unlike RAM or even an HDD, a flash block needs to be erased before being rewritten and erasing is a much, much slower exercise than reading or writing. Usually this is solved by always writing to unused portions of the drive while the system erases pages in the background in a batch, but with no free space there's nowhere to write while erasing.

Meanwhile the 512GB model:

But of course he claims "right now the only thing different is the SSDs, everything else is identical." which is embarrassingly false.

The results of exporting 50x 42MP images?

512GB M2 MBP: 1:45
256GB M2 MBP: 2:00

Which he points out "is a performance difference of 15%!"

He says it like that's proof how bad the SSD is, but remember the raw SSD write performance way up at the Blackmagic test showed the 512GB was 70% faster.

So, 100% more chips leads to a raw performance difference of 70% and a real world performance difference of 15% when pushing 2.5GB of data to a drive that appears nearly full while also swapping. That sounds like the real world performance is better than the benchmark. But that's not the story being told by MaxTech because it doesn't fit the narrative.

Then there's 45 seconds of drama about how disappointing it is that the export took 15 seconds longer.

Then he starts opening 10 browser tabs in Chrome (not Safari) to show multitasking performance. This pushes swap up toward 6GB, so we know the swap is active. No ad blockers, so both machines are running different ads in their browsers.

Same story. Running the 256GB at the edge of capacity.

Of course even the 512GB took twice as long in this scenario, not that the chart they published makes any sense:

Yay for high quality details! (That lower bar should be labeled 4:20 and that's a number not a comment on the presenters state of mind)

His explanation for why even the 512GB is slower? The M2 needs more ram than the M1. Wut?! Same OS, same instruction set, same workload, but the M2 for some reason needs more RAM? And what does this have to do with the SSD?

In this test, unsurprisingly given the drive architecture, available space, additional need for swap, and uncontrolled variables in the testing the 256GB takes 80% longer (7:43). That difference is, for some reason, not attributed to needing more RAM, but entirely to the SSD.

And, of course, that wasn't wasted time, because he's multitasking and doing other work while the export is happening because that's what multitasking means.

And I can't even make sense of the next set of comments about some test with the M1 MBP-- something about doubling the RAM, more tabs, some other apps open (ie. no variable whatsoever) giving these results that I can't interpret:
View attachment 2032247

It's at 12:30 in the video if anyone else wants to try to make sense of it (leave your comments below!).

Then there's some weird sidebar about how their audience is really into tech and is buying 3x as many base model Airs, so imagine how sad it is that people who don't know anything about tech are also buying the same hardware that power users are perfectly happy with.

Now a FinalCut export while multitasking:

What's interesting here is that not only is the SSD near capacity on the 256GB again, we're used to that now, but the 256GB has consistently and significantly higher CPU and GPU utilization throughout the portions of the test we can see. How does one explain that if the export is being bottlenecked by SSD accesses for both export and swap? Doesn't that warrant an explanation and ideally an isolation of that variable?

The 256GB is again slower, no surprise, but he explains that's with "nothing else open", which is straight up wrong because he had a bunch of Chrome tabs open and was playing 4k 60fps YouTube content.

Then what I think is a great comment to close with: "I don't know what would have happened if I had 4 pro apps open and 25 tabs instead".

Yeah, if only there was a way for a reviewer focused on high quality, detailed results to know that... 🤔

His conclusion after trying to run production workflows through a base model Air? It doesn't deserve to exist, and it's only there to get people to upgrade to a 14" pro.


The stated point of the video wasn't to demonstrate that a 256GB SSD 99% full will slow down, it was to, and I quote:

with, ahem, no drama or beef.

The testing here is so flawed and wrapped in hype, to be useless even as an indication of how this will perform in the real world. Any result contrary to the message is quickly buried. It's just a stream of consciousness from someone who fancies themself a pundit.

So can we please all agree that whatever people think about benchmarks, sites claiming to use them like MaxTech are a complete joke? They don't know what they're talking about, they don't know how to do proper testing, they have an agenda behind their data, they're extrapolating beyond what their data can possibly support and it's feeding junk science to a bunch of people who then go into the world and preach it like gospel?

Somebody else will have to tell me if this video from July 1 was the last video they made about SSD speeds as promised, because I refuse to click on another MaxTech video to check.
The thread should end after this post.

Well written and fact based with actual details to back everything up.

Well done 👏
 
No one's defending it, just reminding you that you don't have to buy it.
I'll defend it. It's a consumer laptop. To be used for things like browsing the internet and checking email.

It doesn't need to be capable of rendering a Pixar movie in minutes.

Your parents or mine would buy the base model and be fine with it for YEARS. Macrumors forum members? No, they need Mac Pro performance in a thin, fanless machine for reasons.
 
Rene is the leading voice in the Apple community.

His word is authoritative for me.

The new MacBook Air is the best damn laptop Apple has ever made.
He is the king of the shills for sure. Makes a living acting as if he himself worked for their marketing department. Come to think of this, I do see how you’d like him 😂
 
Benchmark, however flawed it might be, by far is THE most scientific view of a machine’s performance in different metrics and can be compared relatively objectively. Now, whether user takes benchmark seriously or not matters little of other users decisions, but none should dissect the importance of benchmarks recording the progression of our hardware design and evolution.

They are almost completely useless for a lot of users since they really don't test how they use a Mac.

Here is a type of task I do quite often:

* Switch to Teams
* Go into a team folder structure to locate a spreadsheet
* Double click on the file, Teams launches Excel which reads the spreadsheet (often from a server if not cached locally)

There seems to be a complete lack of benchmarking for common office tasks.
 
...and yet I'm getting folks being dismissive of my real world reports of my wife complaining about swap usage slowing down her M1 MBA (8gb RAM) ... and how that will translate to an even bigger problem for many base M2 MBA buyers (with 1/2 the SSD speed to help during Swap)

If she is dissatisfied with her Mac, then it doesn't matter what benchmarks or other people tries to tell you.

I have lots of people in my extended family using Intel-based MacBook Airs with 8Gb of RAM and 128Gb of SSD without any performance issues.
 
If you disagree with benchmarks, I guess you also don’t give scientific research a ton of weight because they don’t really reflect real use either.

So much scientific research is of poor quality especially in the social sciences due to the pressure of publishing. And if it's based on self-reporting I don't trust it at all.

Let's say there is a scientific report on the health of marathon runners. I won't pay any attention to such a report for my own life since I'm not running marathons.

It's the same with most benchmarks. They don't reflect how I use a Mac in a good way and thus are mostly useless to me to determine if I will be happy with a Mac or not. Just as an example, can you point to me a benchmark which measure the performance of Microsoft Office applications for the Mac?

Also, sustained performance is not important to my use of a Mac. Any Mac released in the last 7-8 years has powerful enough CPUs/GPUs for my needs.

What I want from a Mac is great trackpad, as little sound as possible, low weight, Apple Watch unlock, long time on battery power, low footprint, iMessage integration, decent screen with good representation of text and colours, no warm exterior, iCloud Drive integration, iCloud Photo Library integration, bursty performance.

No benchmark can measure that.

That's exactly why most tests have various benchmarks for different application and use cases. You just have to pick the one's that resembles your workload the most.

How about "base model SSD is 50% slower"? :D

That doesn't matter unless you test a real workflow.

Let's say it takes 0.04 seconds to read a file instead of 0.02 seconds. Does it matter?

Using benchmark numbers from The Verge, writing 1Gb of data to the SSD seems to be a difference between 0.3 seconds versus 0.5 seconds. Again will the user notice? Maybe.

How about swapping. Probably it's writing blocks of 16kb of compressed memory to the swap. If that's the case then it sure looks more like random writes to me than sequential write. Will the user notice? Maybe, but swapping often occurs before it's needed in the background while you're doing other stuff.

And almost all the benchmark seems to involve software I don't use: Lightroom, PhotoShop, Premiere, Final Cut Pro, Cinematic 4D, Blender or test the component of the computer one component at the time.

I'm not buying parts, I'm buying a complete system in which I perform certain workflows with certain software. And benchmark can't measure those workflows at all it seems.

The ones that are using benchmark without context

"The SSD sequential read speed is 50% lower" isn't putting a lot of context in it either.

For a lot of workflows you wouldn't be able to point out the difference in a blind test.

It's not about the benchmarks themselves. It's what the benchmarks are revealing the things Apple doesn't want you to know. Eg. the SSD fiasco.

I don't need to know the CPU or GPU performance, or the performance of the SSD.

I need to know if the machine will run the software I use at an acceptable performance to me. And since I haven't seen any benchmark being close to testing the software I use and how I use such software, they are mostly useless to me.

Sorry but I think tou are missing the point. The deniers of the SSD issue claim that this does not affect real world use and most users won't notice. So here is my evidence:

42.5 GB file transfer from External SSD
M2 MBP 256GB: 2:17
M2 MBP 512GB: 0:23

Lightroom Classix 50x 42MP Export (with Safari open with 10 tabs)

M2 MBP 256GB: 6:49
M2 MBP 512GB: 3:13

5min 4K HEVC Export (with Safari open with 10 tabs)

M2 MBP 256GB: 4:23
M2 MBP 512GB: 2:50

So what part of these real world tests are toxic benchmarks? I use all of the above tools on my daily workflows and I see them as real world as they could possibly be. Also the performance difference is massive. I don't see how any of this is toxic.

We're arguing that most people buying the lowest end MacBook will not notice it in most cases. They don't use Lightroom or have 42MP photos. And how often do you transfer 40Gb of stuff when you have a 256Gb SSD?

Why wasn't the Youtuber using Photos and iPhone photos as examples?
Why isn't the Youtuber testing Office applications?

Also if something takes 6 minutes or 3 minutes is such a long time that I won't be sitting there waiting for it to finish. I'll do other stuff and thus it doesn't really matter to me how long it takes within reason.
 
That's the beauty of running a load of benchmarks and other tests in Lightroom, FCPX, files transfers, etc. like many YouTubers do. It helps give an overall picture of things.

And why no test of Office, Slack, Zoom, Teams? Or Adobe InDesign?

I have never used any Adobe software on Mac or FCPX.

Who's fault is it? The youtubers for making the sensationalization videos or the people watching them? What if I like watching them? Is it wrong for me to like that style? Who are you to say what style a YT video should have? Does it harm people?

Yes, it wrong for you to like them. It shows poor taste.
 
That's exactly why most tests have various benchmarks for different application and use cases. You just have to pick the one's that resembles your workload the most.

The problem is that no such benchmark exist.

Can you point to a Mac based benchmark which involves Office and Teams?
