M5 Ultra Mac Studio: is 80-core worth +$1200 and 10 extra weeks over 64-core?
Porespellar · reddit · 2026-10-11
A buyer weighs the M5 Ultra Mac Studio configs: the 64-core ships in 6-7 weeks while the 80-core costs $1200 more and takes 15-17 weeks. With identical Ultra memory bandwidth, they ask whether the difference in prompt processing and token generation speed justifies the premium and wait, noting no inference benchmarks exist yet for the 64-core version.
