That would mean that these comparisons between Threadripper and the M1 Ultra do not reflect CPU performance but instead showcase whatever choice of SSD they've been using.
- LordDragonfang 5y agoL1/2/3 are CPU caches, not SSD. Though there is a good chance these are mostly firmware optimizations, not hardware. So still not an apples-to-apples comparison of cpu design.
- astrange 5y agoBy firmware you mean microcode, but I don't think either of those actually use microcode to control this.
- fivea 5y ago> L1/2/3 are CPU caches, not SSD. Why did you omit the reference to "file system"? Are we supposed to ignore the fact that a linker's main job is reading object files and write the output to a file? I find this sort of argument particularly comical given a very old school technique to speed up compilation is to use a RAM drive to store the build's output.
