I'm not too sure about that. The current 20-core CPU from Apple is inside the Mac Studio, and it has quite a monster of an air cooler. It's obviously going to be much harder to put that (or something more powerful) inside a laptop, even with all the chip improvements...
- zozbot234 4y agoWell of course it does, who wants to be thermally throttled on a desktop-class machine? You're assuming that desktop and laptop use must support the exact same scenarios which is not true among x86-64 users either.
- runeks 4y agoInteresting. Something’s not adding up here, though. 8 cores = “tiny fans basically always off” vs 20 cores = “two huge fans”. Either those two huge fans are running at a very low RPM, or the fans in the laptop are almost as efficient as the huge ones. I highly doubt the latter, so I assume the former is the case.
- sharikous 4y agoReally? MBP 13: 4 performance cores + 4 efficiency cores Mac Studio: 16 performance cores + 4 efficiency cores Not to mention that the more cores you have, the bigger the overhead of e.g. synchronizing between them becomes
- rsynnott 4y agoThe M1 Ultra in the Studio apparently peaks at about 60W, so a laptop based on it would have lower peak power usage than an old 15" MBP (45W CPU, 35W GPU, usually).
