Another YouTube running into throttling issues:

Also tests from our forum members, the CPU throttled down to 800 mhz after 2 min lol...

But it's so thin... so light...

 

[danwat1234]

This is SO obvious... If shouldn't think that a ~4 pound laptop with a thermal solution geared for light weight and low noise, is going to adequately cool a 6- core CPU. Same thing with the Asus Zenbook Pro 15" ... same i9 chip, 4 pound laptop. It's going to throttle really hard at full utilization.
They are tricking the customer into buying the top-end CPU when it won't increase performance except under single core use and very short term multithreaded utlization (time to heat soak).
Those Geekbench scores showing massive multi-core performance increases are just for short term... There is a reason why you can't find a review of these laptops under full, sustained load and look at clockspeeds and temperatures.

MSI & Gigabyte thin gaming laptops with these CPUs do better in this regard. But they too have a hard time cooling the i7-8750h in them. NO thin and light gaming laptop have the i9 chip... so why does Apple think they can keep it cool in their chassis?
There is no way they didn't find this issue in-house, or use common sense.. Apple did this knowingly.

You're just being reactionary. Only idiots are declaring them failures. DL definitely didn't declare it a failure. Whether or not Apple should have been offering that chip...



Who claimed Apple was obsessed? Also wouldn't a better question be "IF thicker laptops are also struggling, why would Apple even offer this chip in a thin, light laptop?" DL did a video on the XPS and said the same thing so he isn't picking on Apple.

He is basically making the point that the i9 chip is not ready to be inside a laptop.I wonder is there any laptop that performs better with i9

To be fair, this isn't so much Apple's fault as it is Intel's. Intel has really dropped the ball in the past couple of years. If they don't right the ship soon, AMD will take over the CPU game for a while. They are late with everything and are having lots of trouble shrinking the dies.

Or, perhaps there would be no issue at all if Apple didn't prioritize/fetishize THIN over any other possible feature of all their models?

Perhaps Apple could offer at least one laptop and one desktop that didn't compromise power, reliability, repairability just so their design teams and Tim could brag about how damn THIN they are?

I'm sorry, that would probably require a few people being pulled away from the really important work being done in emoji technology. Don't know what I was thinking...

Sigh.

Why doesn't MacRumors also posts the Linus Tech Tips video?

He starts right at the beginning by calling out MacRumors as a pro-Apple blog that spins his narrative.

Is that true?

Hoped that MacRumors editors had learned the lesson about YouTubers right now, but looks like they didn't.



Never.

As long as these YouTubers keep receiving money from Apple competitors, and keep generating buzz == views == money == reach == interest from sponsors == more money.

... Timmey, the throttling issues 100% exist i am certain. Unless these macbooks can ramp up the 2 fans to very high, loud speeds, and probably run at 12V instead of 5V, it WILL throttle hard at full utilization trying to cool the i9 CPU. Because physics.
Wait for many more reviews on tech sites and independent showing the same thing.

LinusTechTips has like 10 million subs

6.3 Million.

and their videos are less than 1M views...

Seems legit.

Look at any big YouTuber with lots of subscribers and you will never see even 50% of their subscriber numbers in views. PewDiePie has over 50 million subs his videos get 2-4 million views. Casey Neistat has 10 Million subs, gets about 1-2 Million views.

Linus has 6.3 Million subscribers and gets about 800K to 1.2 Million viewers per video when the content is not sponsored rubbish (which more and more of his videos are).

Just because someone subscribes doesn't mean they are going to watch every video that YouTuber publishes. It just doesn't work that way just like how this forum may have 200,000 signed up users but only a small percentage view threads and post each month.

Here's the thing, Premiere tries to use the CPU as much as possible by going full 100% utilization. The problem with throttling is that there's a severe penalty if you do hit the temperature threshold.

With Final Cut, Apple saw that hitting the CPU at 100% utilization at full clock speeds is actually much slower than rendering at, say, 70% utilization with lower clock speeds. Even without full GPU acceleration, Final Cut would still likely complete a render vs Premiere. Just compare the throttling dips. First is Final Cut, and second image is Premiere.

It doesn’t matter. All the software here is to give workload to the computer. It can’t maintain the BASE clock. End of.

My i9, 32GB,1TB has been eating video work all day with light periodic throttling.

Keep drinking the kool-aid.

And YouTube keeps posting that BS in front of me, I already disliked, reported and selected that I don't want nothing about that.

No use, YouTube keeps pushing it.

The same can be said about EverythingApplePro, Tailosive, MKBHD, etc. etc. etc.

Just because I'm interested in technology, doesn't mean I'm interested in that BS.

Prove what they said is false.

The he

If I was doing heavy rendering, it would not be on a laptop.

The "heaviness" of the rendering is only part of the equation. Time saved is time saved on renders—even if they are ones that just take five minutes each while I'm working away from the office, etc.

 

[justinchao740]

Not good!!! I bought the 13” and I’m completely satisfied!!

13 inch macbook doesnt have the the core i9..... i9 produce MUCH more heat theni5 or i7s

I predicted this thing would need a cooling pad in order to really be used like a pro rendering machine. This kind of confirms it. I'm sure more news will follow, but this is actually worse than I expected.

This quite literally, by definition, proves nothing. It's one isolated incident, as others have already pointed out the software used could be to blame. And we don't know if his machine is defective. This is literally a completely extraneous date point, at this juncture.

 

[geromi912]

Isn't the entire point of the "turbo boost" on these Intel CPUs to allow the CPU to run at a higher than rated clock speed for shorter periods, then throttle down to the "regular" speed once the thermal threshold is reached?

IE, it's working as designed?

It can’t even maintain the BASE clock. BASE 2.9 ghz. NOT turbo. Can you read?

For the LAST TIME.

It's NOT the software. Did you not see the part where he put it in the freezer, the render time went down from 40 min to 27 min?

So far, we have 2 forum members reporting this issue, as well as 3 credible YouTubers.

 

[Baymowe335]

So tell us the difference in software and hardware from the last MacBook to the latest. What has changed? Why would a new Intel chip with no new instructions suddenly get taxed more?

The 8th gen is identical to 7th with the exception of more cores. Even if there was 'random cpu taxes', it would also be in the 7th gen, so your 'point' is moot either way

Again, we'll see with more testing.

 

[Derived]

As always, there are people that instantly write comments dismissing this and/or defending Apple. I really don’t see the need in doing so in this case.

For the past few years we’ve seen the BTO CPU throttle under load, in all MacBooks. With 8th gen chips, this is taken to another level and at a point where Apple need to sort it out. They skimp out on things as cheap as thermal paste, which could significantly improve the situation, along with the obvious re-engineering of the thermal situation. It really is inexcusable for Apple to have this situation. It’s yet another negative of the thinner MacBook Pro design.

There isn't a laptop on god's green earth that doesn't throttle under continuous, heavy load. I'm quite confused as to how this is an "Apple problem" instead of a "laptop problem" - assuming this test is even a relative data point.

It could be. New computer, different situation. We'll see with more testing and software updates. Intel has fixed architecture issues with software before.

This thread, quite literally, already has 4 different examples of peoples machines throttling

The last time? How about a first time? That's my first comment on this thread.

That also proves nothing...do you understand how physics works? If the software causes the CPU to heat up unnecessarily, of course cooling it down will improve performance. That doesn't change the fact that the software may be poorly designed in the first place.

He also made the point the expectations for a laptop are out of whack. If you are doing this type of processing, get a machine that is meant for it. People using Premiere that abandoned the Mac ecosystem did not jump to a laptop, they jumped typically to an HP workstation (Xeon - with configurations that go north of the iMac Pro by a considerable amount).
For Final Cut Pro the laptop will work... but really it is still the job of something larger. Size the machine to what you need, and then if you need a laptop from time to time - just get a lesser laptop for all processes that are not workstation grade workflows.

I haven't tested the new macbook out but I have a 17" Alienware R5 laptop with the new 8th gen 6 core chip. Even in the big Alienware that weights in around 9lbs due to all of the heatsink copper it uses, the fans still wind up and are very audible while compiling code with visual studio etc.

I can't imagine the i9 in a macbook pro form factor if I were pushing it as hard as I do in windows/visual studio/gaming...the Alienware is gigantic in comparison, probably 3 times thicker, much wider/longer and the copper heat sinks are loaded off the back end so the fans can push the air away.....all designed for cooling in mind and it still has to pump the fan RPM up.

That said, my Alienware never throttles....but I wouldn't expect it to given the cooling system.

The same software running two identical intel chips (Except one has two new cores and thermal issues) is just suddenly going to develop issues on the new chip?
