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&#x2F;sec generation speed

  Prompt size    8K    64K   128K   256K
  RTX 5090 PC    59    51    44     n&#x2F;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://www.macstories.net/stories/m5-ultra-mac-studio-review-the-dream-mac-for-local-ai-agents/#mx-pc" rel="nofollow">https://www.macstories.net/stories/m5-ultra-mac-studio-revie...

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

    can confirm.
    I dont' know why people spend huge money on these and Spark. The 5090 is running qwen 3.8 at 200+ tps!! That's 1-2 orders of magnitude faster.

    same reason they spend huge amounts of money on rolexes when seikos work better (the tech crowd isn't immune from vanity).

    If you seriously think apple products are nothing but a status item, you're deluding yourself and probably have been for decades.

    If you seriously think apple cares about anything other than cell phones, you're deluding yourself and probably have been for decades.

    They've been selling phones for less than 20 years at this point? Though I suppose 1.9 is not equal to 1, so it gets the plural.

    ...did you mean profit? I don't think they're manufacturing iphones just on the hope they delight you. This is also true of Google et al.
    I don't get these weird parasocial emotional attachments/beefs people have with brands. Talk to a therapist.

    brother my point is they don't care about their product offerings outside of their phones. this post/thread is about one of their product offerings which is not a phone which is inferior to their competitors'. simple.

    My M1 Pro MBP is 6 years old and continues to be the best computer I own, so if that’s Apple not trying, god help everybody else once they do.

    What in that thread is particularly impressive or noteworthy? According to the benchmarks I've seen, M6 raster performance is actually less efficient than M5 in many scenarios.
