For me, think about that memory bandwidth. No other CPU comes even close. A Ryzen 5950X can only transfer about 43GB/s. This thing promises 400GB/s on the highest-end model.

And only 10 cores so a 5950x completely wreck an M1.

A 5950x uses ~4 times as much power.

Based on the numbers it looks like the M1 Max is in the RTX 3070-3080 performance territory. Sounds like mobile AAA gaming has potential to reach new heights :D

Who actually supports MacOS though? Didn't valve just give up?

Apple won't support Vulkan, and moltenVK isn't good enough for DXVK. macOS also doesn't support eventtfd system calls like linux.

Pretty much the only options are crossover/wineskin engines, or parallels.

Ah yes, the naming. Instead of M2 we got M1 Pro & M1 Max. I'm waiting for M1 Ultra+ Turbo 5G Mimetic-Resolution-Cartridge-View-Motherboard-Easy-To-Install-Upgrade for Infernatron/InterLace TP Systems for Home, Office or Mobile [sic]

It's scaled up M1. No new cores, no new modules. Just more of everything. I would've been disappointed if it was called m2.

The big ticket items: Hardware-accelerated VSCode cursor animation. Dedicated button for exiting vim. Additional twelve function keys, bringing the total to 24; further, vectorised function key operations, so you can execute up to 12 "nmap :set background=dark" statements in parallel. Dedicated encode and decode engines that support YAML, TOML and JWT JSON. A neural engine that can approximate polynomial time registe…

Solid gold

Nope, just Silver and Space Grey.

I know Apple has a translating feature called Rosetta. But what about virtual machines? Is it possible to run Windows 10 (not the ARM edition but the regular, full Windows 10) as a virtual machine on top of an Apple M1 chip? It looks like UTM ( https://mac.getutm.app/ ) enables this, although at a performance hit, but I don’t know how well it works in practice. What about Parallels - their website suggests you can ru…

If they're entering the workforce, gift them for their personal use. The office should provide them with the laptop instead of a personal one.

AFAIK their recycling is shredding everything, no matter if it still works and separating gold and some other metals.

When you trade-in your Mac you are asked if the enclosure is free of dents, turns-on, battery holds charge etc. Strange that they would ask these questions if they were simply going to shred the device.

Why not? It does sound micer that way and some customers may actually think they resell them just because of this...

Just some genuine honest curiosity here; how many workloads actually require 64gb of ram? For instance, I'm an amateur in the music production scene, and I know that sampling heavy work flows benefit from being able to load more audio clips fully into RAM rather than streaming them from disk. But 64g seems a tad overkill even for that. I guess for me I would prefer an emphasis on speed/bandwidth rather than size, but…

Can’t answer for music, but as a developer a sure way to waste a lot of RAM is to run a bunch of virtual machines, containers or device simulators. I have 32GB, so unless I’m careless everything usually fits in memory without swapping. If you got over things get slow and you notice.

My laptop has 128GB for running several VMs that build C++ code, and Slack.

So with 57B transistors for the M1 Max you can fit the AMD 5800H (10 B) and the RTX 3080 Ti (28 B) and have 19B transistors left. So the performance should be top notch but cooling and power requirements will be quite high. So battery life of 21 hours is quite the achievement. Still, i prefer the open architecture of the PC any day.

https://en.wikipedia.org/wiki/Transistor_count It seems to be way beyond any CPU for end users and even some servers like AWS Graviton 2

I think only company with more transistors on the chip is Cerebras.

What is it about the M1 architecture that makes it so speedy compared to x86 chips? Is it the Risc instruction set? The newer node process? Something else?

RISC is a big part of it, and enabled the biggest part, which is Apple got to design their own SoC. And they have their own OS, so they can cause a complete paradigm shift without having to wait for the OS company/collective to come around.
