Be interesting to see the reviews. Maybe I just don't understand engineering enough but I can't see the M2 MBA sustaining 20% better speed without thermal throttling under consistent load. Probably the 13 Pro is where we'll see the difference sustained. Stay tuned for a Max Tech video showing that an M1 Air can maintain performances better over long periods than an M2 Air which will throttle to lower than M1 speeds in order to cool down. Maybe.
 
12% is not internal design improvements, much of that is clock speed increases as outlined in the tweet.

Clock + huge L2 cache + RAM bandwidth

We've seen this formula before with Intel with lithography stalls. Some people here don't seem to get it.

Architecture changes allow such improvements. Memory controller enhancements or increasing caches will increase performance alone. Not to mention the extra 700 MHz the M2 is now supporting.

All that however comes at a cost of power.
 
Also, that 20% bump came at the expense of power consumption.

Source?

Increasing clock does of course increase power consumption. However, we also know that the e-cores in particular are much faster, and therefore will be used (in favor of the p-cores) a lot more compared to the M1. The A15 iPhones overall have much better battery life than the A14 ones, despite a higher clock.

So, what makes you so sure the M2 has higher power consumption?
 
Yes, these new M2 MacBooks could have worse battery life under load than the M1 MacBooks.
M2 MacBook Air should throttle quite a bit, especially under GPU load.
No and not really.
The M2 MacBook Air got a nice bump in battery capacity, going from a 49.9‑watt‑hour lithium‑polymer battery in the M1 to a 52.6‑watt‑hour lithium‑polymer battery in the M2, so any increase in power consumption should be quite balanced out and, like Apple says, the battery life in the end should be about the same.
As for the fan, if it’s anything like M1, The actual difference that it makes is extremely minor
 
Apple just did 12% in 15 months without a new process, just from internal design improvements. And they piled on a bunch more multicore and GPU performance at close to the same power usage and price point.

It's from TSMC N5 to N5P node improvement.

I was in the local Apple store checking out the latest 15” MBP. I lust for it so. I have the credit to buy it interest free.

Alas, my wife would break my fingers individually if I brought that thing home.

These processing power increases are insane. My intel MBP is looking long in the tooth.

I wonder if I could soften the blow of a new one by handing my current one down to her. This worked last time, and hers is getting a bit long in the tooth…


tell her how much you would save on electric bills.

It looks like the majority of the target audience for Airs are better off with the original Air. They won’t benefit much from the M2 since single core performance is what really matters for them, and that’s only 12% faster, but you need at least a 20% increase to see a real world difference.
They might not benefit much from the new processor but they certainly will from the new design, better WebCam, bigger Display, better speakers, and MagSafe.

$200 buys you:

  • a slightly faster CPU
  • a much faster GPU
  • a lighter, thinner chassis with smaller bezels
  • a much better camera
  • a much better sound system
  • MagSafe
If you can do without those, the M1 Air is a great laptop. If you like those, the M2 Air is also a great laptop.

I'll use Apple's own charts:
Apple-WWDC22-M2-chip-CPU-perf-vs-power-01-220606.jpg

See the how the M2's curve starts after the M1's curve? That's extra power at idle

GPU? Same story but much more noticeable as to reach the peak performance there are around an extra 3-4 W consumed vs the M1

Those Max Tech clickbaiters strike again with cherry picking results. If comparing M2 MBP to M1 MBP it's only 9.5% for ST and 14.9% for MT so minor bump credited to TSMC improved 5nm node.

As usual, you're the one doing the cherry-picking—while falsely accusing someone else of doing exactly what you're doing (I can't comment on MT's other stuff, but he clearly wasn't cherry-picking here).

You've cherry-picked a single high result for the the M1 MBP from the Geekbench Browser to use as a comparator.

Instead, the more honest and reasonable thing to use as a baseline would be what's listed on Geekbench's Mac Benchmark Chart, which is based on an average of multiple results ("To make sure the results accurately reflect the average performance of each Mac, the chart only includes Macs with at least five unique results in the Geekbench Browser.") (see screenshots below).

Of course, this will get more accurate once we also have multiple results for the M2. But until we do, what I described above is the best we can do, not what you did:

1919/1707 => 12% higher SC
8928/7395 => 21% higher MT

I’m also guessing you can add another year or two of OSX updates. The

Could someone explain to me what are the real world benefits of the performance gains here? Does it let you go home and cook dinner earlier, meet with friends at kareoke on time, spend more quality time with family?

How is it gonna help someone who only benchmarks Apple hardware and unbox products for a 7 to 10 minute video?

Will this improve the performance of typing in Microsoft Word, will watching Apple TV+ be any better?

Are there any benefits to an app developer who already has a feature rich app; 95% of the features a user is not using anyway?

Or is it just a nice thing we can say we have like someone with a Ferrari but never drives it at full speed and only goes to Target and on Saturdays?
Just like it’s been for the past decade and a half or so, going right from one generation to the next rarely shows a dramatic improvement, no matter who’s making the processor.
The 2018 MacBook Pro‘s weren’t that much faster to someone upgrading from the 2017 MacBook Pro‘s if you get what I’m saying.
Same situation here.
Going from M1 to M2 might not be that big of an improvement, might not let you do your work that much faster, might not get you home that much quicker.
But moving from an Intel MacBook Air to this M2 certainly will show dramatic improvements and be much quicker.
That’s who this is targeted at, just like with the majority of products these days.
And likewise going from M1 to M2 might not be that big of a difference, but in a couple years going from M1 to M5 is going to be quite a boost.

Iterative y-o-y improvements aren't necessarily about enabling new use cases.

But yes, walk another eight years down the road and the M1 MacBook Air will in fact be annoyingly slow for typing in Microsoft Word and watching Apple TV+, because everything else will have become slightly more complex. macOS will gain features you use (or not) that take up little bits of performance. As will the Word and TV apps.

Na, it’s certainly going to throttle but it will not be slower than an M1 even under heavy stress because of the speed improvements of the efficiency cores

Let me address each point in turn:
1) Does it let you go home and cook dinner earlier? NO.
2) Meet with friends at kareoke on time. YES. PUNCTUAL KARAOKE IS A KEY BENEFIT OF THE M2, SINCE IT'S HARDWIRED INTO THE NEW NEURAL PROCESSOR.
3) Spend more quality time with family. NO, THIS IS REDUCED BY NEW MAC PRODUCTS.

As others have mentioned, there is typically little real-world benefit to individual generational changes (the exception would be if, even if the average performance doesn't change much, certain specific workflows are made much faster). But these changes are nevertheless interesting to discuss from a technological point of view.

And, of course, it's the accumulation of these small generational changes that are needed to get significant improvement in the long term.

Everybody remembers those graphs from Apple with a steep ramp in performance.

Single thread:
  • A8 to A9 - 55% increase
  • A9 to A10 - 40% increase
  • A10 to A11 - 20% increase
And keep in mind A10 was riding on the same 16nm process as A9.

We're just seeing smaller and smaller deltas. What used to be 20% increases for single-thread are now multi-thread.
