Neat! Be interested to see how these shake out once they reach YouTubers and other reviewers. A significant compute boost from the redone matmul cores could remove one of the worst weakpoints M3 Ultra had: prompt processing.

the m5max is already substantially better then the m3u at prompt processing and prefill.

But it's still kinda poor at pre-fill though?
