It's not relevant for single threaded code, but then neither is doubling the core count from 4 to 8 or 16.
- ksec 3y agoI dont think they care as much as in the case of Multi Core era. It is easier just to sell more cores.
- nullc 3y agoBoth intel and AMD's hyperthreading seems pretty lame compared to Power's for some reason. One cause may be that with just two threads the chance that both get blocked on a memory access is pretty good.
