Out of curiosity, is Apple's M1 processor seemingly faster because it is actually more similar to a normal CPU progression but all the other common CPU's - x86 - had retroactive performance hits due to patching Spectre.
And therefore M1 seems so much more faster than it otherwise would?
- creshal 6y agoARM CPUs, including Apple's have been found vulnerable to some SPECTRE variants. As far as I understand, M1 already contains hardware mitigations for all known ones, but so do the latest Intel/AMD chips. (Or rather, contain fixes for all but these latest ones.)
- jlouis 6y agoI'm more inclined to believe M1 is fast because it's a modern design where every part of the architecture is under Apple's control. In particular, the design uses a memory hub with the memory chips very close to the CPU core. And it has a massive L2 cache on top.
