Which takes a $20k thunderbolt cluster of 2 512GB RAM Mac Studio Ultras to run at full quality…

Most benchmarks show very little improvement of "full quality" over a quantized lower-bit model. You can shrink the model to a fraction of its "full" size and get 92-95% same performance, with less VRAM use.

And that's at unusable speeds - it takes about triple that amount to run it decently fast at int4.

Now as the other replies say, you should very likely run a quantized version anyway.

Depending on what your usage requirements are, Mac Minis running UMA over RDMA is becoming a feasible option. At roughly 1/10 of the cost you're getting much much more than 1/10 the performance. (YMMV)

"Full quality" being a relative assessment, here. You're still deeply compute constrained, that machine would crawl at longer contexts.

Which while expensive is dirt cheap compared to a comparable NVidia or AMD system.
