Please list quantization for benchmarks. I'm assuming that's not the full model because that would need 256GB and I don't see a Studio model with that much memory, but q8 doubles performance and q4 quadruples it (with corresponding loss of quality).

You can just buy a complete server from a vendor or eBay, but this costs more because they'll try to constrain you to a particular configuration that includes things you don't need, or overcharge for RAM etc. Which is basically the same thing Apple does.

Whereas you can buy the barebones machine and then put components in it, which takes like fifteen minutes but can save you a thousand bucks.

That is with 4-bit quantization. For practical purposes I don't see the point of running anything higher than that for inference.

That's interesting though, because it implies the machine is compute-bound. A 4-bit 120B model is ~60GB, so you should get ~13 tokens/second out of 800GB/s if it was memory-bound. 7/s implies you're getting ~420GB/s.

And the Max has half as many cores as the Ultra, implying it would be compute-bound too.

6.3 tok/s has been demonstrated on q4_0 Falcon 180B on the 192gb Mac studio: https://x.com/ggerganov/status/1699791226780975439?s=46&t=ru...

A lot of people are reporting low context sizes tokens per second without discussing how slow it is at bigger sizes. In some cases they are also not mentioning time to first inference. If you dig around /LocalLLaMA you can find some posts with better bench-marking.
