It would be odd for me if "Max" were not the "maximum".

That's still a bad naming convention. It won't be the maximum forever.

But it will the the max M1 forever. When M2 comes around, that's a different class.

My family has 3 MBP's. 2 of them are 10 years old, 1 of them is 8. When your laptops last that long, they're good for the environment.

Don't know the clock speed but 8 cores at 3Ghz working on 128bit SIMD is 8 3 16 = 384GB/s so we are in the right ball park. Not that I personally have a use for that =) Oh, wait, bloody Java GC might be a use for that. (LOL, FML or both).

But the classic SIMD problem is matrix-multiplication, which doesn't need full memory bandwidth (because a lot of the calculations are happening inside of cache). The question is: what kind of problems are people needing that want 400GB/s bandwidth on a CPU? Well, probably none frankly. The bandwidth is for the iGPU really. The CPU just "might as well" have it, since its a system-on-a-chip. CPUs usually don't care to…

Yeah the marking phase cannot be efficiently vectorized. But I wonder if it can help with compacting/copying phase.

Also for me the process sounds oddly familiar to vmem table walking. There is currently a RISC-V J extension drafting group. I wonder what they can come up with.

Has anyone tried extremely graphically intense gaming on these yet, I actually would love to consolidate all of my computer usage to a single machine, but it would need to handle everything I need it to do. $2000 for a laptop that can replace my desktop, is not a bad deal. Although that said I’m in no rush here.

Gaming is a non-starter on MacOS since 2018. You can get certain, specific titles working if you pour your heart and soul into it, but it's nothing like the current experience on Linux/Windows unfortunately.

Darn.

Hard pass then. I already have a pretty fast Windows laptop. The only real issue is it sounds like an helicopter underload. ( It also thermal throttles hard ).

Apple, the company that requires the entire panel to be replaced by design when a 6 dollar display cable malfunctions, is proud to announce its latest marketing slogan for a better environment.

As long as they plant a tree every time they replace a panel, it should be fine?

It makes me sad that no one will never be able to build anything with those chips. I imagine there could me many, many innovative products built with these chips if Apple sold them and supported Linux (or even Windows).

...or just released the full documentation for them. Apple being Apple and wanting full control over its users, I don't see that happening. I really don't care how fast or efficient these are, if they're not publicly documented all I think is "oh no, more proprietary crap". Apple might even make more $$$ if it wanted to open up, but it doesn't.

What do you mean? All the APIs (Xcode SDK, Metal, ML, etc) required to build on their devices are very well documented.

Obsession with emissions has really made people start to miss the forest from the trees.

Emissions affect everyone on the planet, no matter where they happen. But polluting the ground or water only happens in China, so a lot of Americans that care about emissions don't care about the other types of pollution, because it doesn't affect them.

I always thought it was strange that "integrated graphics" was, for years, was synonymous with "cheap, underperforming" compared to the power of a discrete GPU. I never could see any fundamental reason why "integrated" should mean "underpowered." Apple is turning things around, and is touting the benefits of high-performance integrated graphics.

Video game consoles have been using integrated graphics for at least 15 years now, since Playstation 3 and Xbox 360.

Longer since integrated graphics used to mean integrated onto the north bridge and it's main memory controller. nForce integrated chipsets with GPUs in fact started from the machinations of the original Xbox switching to Intel from AMD at the last second.

This exact question was asked a year ago when the M1 was announced. In the year since, their laptop market share increased about 2% from 14 to 16%[0]. The reasons for this are: 1. When deciding on a computer, you often have to decide based on use case, software/games used, and what operating system will work best for those use cases. For Windows users, it doesn't matter if you can get similar performance from a Macbo…

All good points but: 1) In the pro market (audio, video, 3d, etc) performance is very relevant. 2) Battery time is important to all types of laptop users. 3) Apple is certainly working on more desktop alternatives. 4) You don't need move all your devices into the closed ecosystem just because you use a Mac. Also, some people just don't want to use macOS on principle, but I'm guessing this is a minority. > AMD's produ…

In the pro market especially you have people who are stuck using some enterprise software that is only developed for PC like a few Autodesk programs. If you are into gaming many first party developers don't even bother making a mac port. The new call of duty and battlefield games are on every platform but switch and mac OS, and that's increasingly par for the course for this industry since mac laptops have been junk to game on for so long.

I think you misread the graph. https://www.apple.com/newsroom/images/product/mac/standard/A... The graph there shows that the new chip is higher power usage at all performance levels.

Not all; it looks like the M1 running full-tilt is slightly less efficient for the same perf than the M1 Pro/Max. (I.e., the curves intersect.)

Yes, but only at the very extreme. It's normal that a high core count part at low clocks has higher efficiency (perf/power) at a given performance level than a low core count part at high clocks, since power grows super-linearly with clock speed (decreasing efficiency). But notably they've tuned the clock/power regime of the M1 Pro/Max CPUs that the crossover region here is very small.
