Haha, bloody hell, what a monster of a chip. I find my M1 Max already remarkably fast. The change is so huge. It's like in the old days when you'd get a new computer and it felt like it could do things before you could think of doing them.

But surely the GPU things can't be real? The GPU in the M1 Ultra beats the top-of-the-line Nvidia? That's nuts.

Looks like all the people saying "just start fusing those M1 CPU's into bigger ones" were right, that's basically what they did here (fused two M1 Max'es together).

And since the presenter mentioned the Mac Pro would come on another day, I wonder if they'll just do 4x M1 Max for that.

It sounds like the chip is fast but I wonder, if like other M1 products, the computers built with it will be fairly restricted, like a console, in terms of the hardware they're able to use (not being able to boot off external HDDs, problems with thunderbolt 3 compatibility in peripherals, having to use abstraction layers to run most of the software world indirectly or have specific porting projects dedicated to M1, etc).

Well they were only correct that Apple managed to hide a whole section of Die Image. ( Which is actually genius ) Otherwise it wouldn't have made any sense.

Likely to be using CoWoS from TSMC [1] since the bandwidth numbers fits. But needs further confirmation.

Given that it's basically double the performance of the Max, with massive memory bandwidth, seems reasonable to me. But Apple always fudges things a bit. Like, which Nvidia exactly is this being compared to, and under what workload exactly?

I wonder if the max 128GB graphics memory opens up some applications that would not have been viable before?

Not really. Thanks to the GPU interconnect NVLINK we have system 320GB. https://www.deltacomputer.com/nvidia-dgx-a100-320gb-3ys-edu....

There are even some with 640GB. This is at a different price point though.
