I guess it depends on your definition of perfect - cheap, good or fast.

This thing is probably going to cost at least $20K USD.

Edit:

"Next year's base M7 processor is expected to arrive in the first half of 2027 and will also upgrade memory bandwidth to about 240 GB/s."

That's...really fucking slow. What's the goal here - CGI, engineering sims, game dev etc? 1.5TB is cool but at 240GB/s that will crawl for AI use.

Comparison: this is about $100K, for 7.2TB/s, 252GB VRAM (+500GB system ram, so closer to 750GB total)

    It’s likely wrong reporting, the m5 ultra gets 614 GB/s today. The m3 pro gets over 800. The rumored m5 pro is 1.2TB/s. Likely this will be 2.4 TB/s, but half the reason for high bandwidth in nvidia chips is somewhat offset in the unified scheme. Mlx needs a lot less copy data around when the gpu can just read it directly.

    Something got reported on incorrectly because the M5 Max's have 614 GB/s today, and the Ultra M4 machine's (not laptops) are 819 and that's 3 generations behind a M7 if they make an M7 ultra machine.

    $ for $ you'll get more video ram than paying for a 5090, but it won't be as fast and can't train well.

    Before the ram price decable, you could get a 192gb M4 Ultra for ~10k CAD.
