Apple's M1 processor has a number of tricks. The most clever one for the x86 transition is certainly the ability to emulate its memory ordering modes. https://t.co/Z1CUnsyNL1

I don't like and no longer need use a Mac for work, but each week I'm more and more interested in the M1 hardware changes and clever approaches to speed up things, between Apple and AMD the mostly stagnant Intel should pick up the pace: https://t.co/3qr8pcfy6J

He's an expert troll, but I do enjoy this tweet - optimizations make M1 Macs "seem" faster, by running JavaScript faster. That's not a use of the word "seem" I was aware of.https://t.co/etJSm0fHzJ

Great ? on why the M1 can do the crazy things it do. https://t.co/WSg1gs5rWF

— Dark Mode Dave (@davemark) November 26, 2020

Okay. I had been skeptical about M1 Macs. These explanations remove my skepticism entirely. These are *good* tricks, but they are also *achievable* tricks. Also, it's not that M1s are massively fast and efficient. They are massively fast *or* efficient. https://t.co/g0YvgbmuBq

As a software dev, I’m wasn’t sure how to process “cheating”. It either works it it doesn’t. And in this case, it seems to work fine. But us software guys are, well, soft. I’m interested though, if you have a moment, what’s the ‘conventional wisdom’ that’s being ignored here?

— stuartd (@stuartd) November 28, 2020

Great thread on Apple’s M1.

As the thread says, none of this is black magic, just “all the various things have been executed really well, leading to a combined result that is a great leap forward.” https://t.co/KNE49HxFaL

— Drew Thaler (@drewthaler) November 26, 2020

The standard way of designing a CPU is for general purpose use. Apple didn't do that -- they designed it for their own code and nobody else's. In retrospect, this is obvious of course.

I did some tests on two very similar (64GB/same SSD model, Vision D mobos) “Golden” Hackintosh builds with a 3900x vs 10850k. Basically they are close enough that I don’t think you could tell the difference in actual use. So if you are doing one, just go with Intel. pic.twitter.com/MhuuPh2OE2

Once again, Apple has executed excellently & admirably with their latest silicon efforts. I'm thoroughly impressed with the combination of clever solutions in M1, culminating in a momentous lead.

Very interesting thread on various choices Apple made for the M1 processor

It also shows how important it is for Apple to control the full stack, from the language (Swift), down to the silicon (contains instructions to optimize the reference counting memory mechanism Swift uses) https://t.co/CSSRBpBM6a

— Nicolas Fonrose (@nfonrose) November 28, 2020

This is by far the best info I've seen on the new Apple M1 CPU.
Many points should be valid for the A-line CPUs, too.
Explicit optimization for JavaScript explains the iPhone's fantastic performance, as does iOS' reference counting vs. Android's garbage collection. https://t.co/LNxRjUVCWN

This is the first Mac since the PowerPC era that’s definitely worth the money... I might get one and I don’t even like OS X. Well done, Apple...

— FuriouslyAdrift (@AdriftFuriously) November 26, 2020

Of course I didn't mean any negative connotations by "cheat". I mean only that there's convention wisdom about what you shouldn't do, and Apple did it anyway. :)

— Robᵉʳᵗ Graham?, provocateur (@ErrataRob) November 27, 2020

E.g instructions optimized for JavaScript. In the 80s there were processors optimized for Lisp and Smalltalk, but these were behind in other areas because this of low volume. M1 also gets other things right . https://t.co/vxR2KjNmmC

— Willem van den Ende (@mostalive) November 27, 2020

This thread seems to 1) imply Apple “cheated” by getting x86 code on ARM to run better than Microsoft managed. Why not say “made a better choice”?
2) imply that optimising Javascript (there’s a lot of it on the web) is underhand. No, it’s smart. 3) suggest DTKs are sneaky. Huh? https://t.co/oKQ8MNK5BU

Apple CPU tricks: memory reordering, JavaScript support, ref counting https://t.co/HyURCW3T0I (https://t.co/UtC4m1HOtO)

— Hacker News 100 (@newsyc100) November 28, 2020

In hindsight it’s kind of amazing that it has taken until now for chip designers to optimize CPUs in ways specific to making JavaScript faster. JavaScript is not going anywhere, and it is a huge bottleneck for a lot of software a lot of people run all day.

— John Gruber (@gruber) November 28, 2020

Snapdragon 875 has a 4mb L3, M1 has a 12MB!!! L2. It’s not “magic”, Apple just wins by using a ton more die. Apples cost savings from vertical integration are spent on silicon, which results in a product that is really hard to beat. https://t.co/OkhGpcvlUm
