That's the trick: they can't make single cores faster so they just throw more cores at the problem and call it a day. Obviously that doesn't work but who cares?

- plopz 7y agoThats why they should sell cpus that sacrifice security for speed. I'll take a cpu thats vulnerable to spectre/meltdown if its 20% faster.
- paines 7y agoYou mean slower
- vbezhenar 7y agoAre you sure that they sacrifice speed for security? It's not obvious to me. Hardware fixes are supposed to be fast. That 20% slowdown comes from software implementation (and you can actually disable it).
- plopz 7y agoI wasn't aware that the fixes for spectre and meltdown had no impact on performance.
- waste_monk 7y agoAt least on Linux it's pretty easy to disable the mitigations: https://linuxreviews.org/HOWTO_make_Linux_run_blazing_fast_(again)_on_Intel_CPUs https://linuxreviews.org/HOWTO_make_Linux_run_blazing_fast_(... I'm not sure how easy it is to disable on Windows though.
