Key values in the press release:

- Up to 1.5x the CPU speed of iPad Pro's previous M2 chip

- Octane gets up to 4x the speed compared to M2

- At comparable performance, M4 consumes half the power of M2

- High-performance AI engine, that claims 60x the speed of Apple's first engine (A11 Bionic)



Apple claimed M3 was 1.35 the speed of the M2. So the M3 vs M4 comparison isn't that impressive. Certainly not bad by any means, just pointing out why it is compared to the M2 here.


The other reason it is compared to the M2 is that there are no iPads with M3s in them, so it makes sense to compare to the processor used in the previous generation product.


It seems pretty reasonable to compare it against the last-model iPad, which it's replacing.


People make this comment after every single m series release. Its true for intel too, worse even. Changes between like 8th and 9th and 10th gen were like nill, small clock bump same igpu even.


While I completely agree with your point, the M chips is a series of chips. The iPad M2 is different than the MBP M2 or the MacBook Air.

It’s all just marketing to build hype.


No, it's the same as the MB Air.


>- Up to 1.5x the CPU speed of iPad Pro's previous M2 chip

What I want to know is whether that ratio holds for single-core performance measurements.


Here’s the benchmark:

> Up to 1.5x the CPU speed

Doesn't it mean "1.5x speed in rare specific tasks which were hardware optimized, and 1x ewerywhere else"?


I mean, we'll have to wait for proper benchmarks, but that would make it a regression vs the M3, so, er, unlikely.


At this point I read "up to" as "not"...
