    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...

      Thank you for this. I wish Apple focused their silicon design on improving the TTFT metrics but coming from an M3 Pro, it still looks laggard compared to Nvidia&#x27;s TensorCores in the 5090.

      Maybe Apple is an acquisition away from changing that balance.

        The rumor on Apple&#x27;s processor roadmap is that they&#x27;re skipping other M6 variations (all previous generations had Pro and Max, a few had Ultra) in order to focus on the M7 generation for AI reasons. What exactly the M7 improvements are who knows.

          &gt; What exactly the M7 improvements are who knows.

          &gt; Apple&#x27;s planned M7 Ultra chip is being designed to support up to 1.5 TB of unified memory and to push AI performance toward the class of Nvidia&#x27;s Blackwell accelerators
