    The numbers I was most interested in are tucked away in a chart towards the bottom - the speed comparison of the Mac Studios v.s. a RTX 5090:

      Qwen3.8 27B tokens/sec generation speed

  Prompt size    8K    64K   128K   256K
  RTX 5090 PC    59    51    44     n/a
  M5 Ultra       48    39    32     24
  M3 Ultra       31    23.5  20     15
    A whole bunch more comparison numbers in this section: <a href="https:&#x2F;&#x2F;www.macstories.net&#x2F;stories&#x2F;m5-ultra-mac-studio-review-the-dream-mac-for-local-ai-agents&#x2F;#mx-pc" rel="nofollow">https:&#x2F;&#x2F;www.macstories.net&#x2F;stories&#x2F;m5-ultra-mac-studio-revie...

      Those RTX 5090 numbers are bad. You can get over 200 tps with ninfer using NVFP4 and MTP.

        ... or with llama.cpp with MTP.
