The m1 max is about equal to a desktop nvidia 3060ti (based on Apple’s own labeled slide released today) which is fine but not exactly amazing. It’s great for 4K and 8k video editing due to the UMA and multiple dedicated video blocks. The CPU is quite fast as well, Intel Alder Lake surpasses it but not by much.
Ultra is a LOT faster at a high price ($5,000 min buy in for the full 64 GPU cores). Apple says it’s roughly the speed of an nvidia 3090 which of course is a monster.
The m1 max was already overkill for video unless you do a lot of 3D graphics.
Keep in mind this is a locked down machine with no slots. When nvidia’s 4000 series come out, which will be 2x as fast as the 3000 series, eventually you can upgrade. Not so with the studio. It’s the old trashcan Mac Pro all over again.
I think $5000 is very high for a PC you can buy at similar speed for $2,000 to 2500 less. I have a m1 max laptop but it’s different. It’s a (current) Mac Pro that I can cart around and use on battery for hours. There’s really no comparable Pc laptop and Macs are better for creativity.
But if you edit with Resolve or Adobe, or render 3d graphics … or of course gaming, the Mac Studio is a huge ripoff. The Pc will be as fast at half to 2/3 the price.
