Linus Torvalds Says Intel Needs To Admit It Has Issues With CPUs

troublemaker_23 shares an article from ITWire: Linux creator Linus Torvalds has had some harsh words for Intel in the course of a discussion about patches for two bugs that were found to affect most of the company's processors... Torvalds was clearly unimpressed by Intel's bid to play down the crisis through its media statements, saying: "I think somebody inside of Intel needs to really take a long hard look at their CPUs, and actually admit that they have issues instead of writing PR blurbs that say that everything works as designed... Or is Intel basically saying 'we are committed to selling you shit forever and ever, and never fixing anything'?" he asked. "Because if that's the case, maybe we should start looking towards the ARM64 people more." Elsewhere Linus told ZDNet that "there's no one number" for the performance drop users will experience after patches. "It will depend on your hardware and on your load. I think 5 percent for a load with a noticeable kernel component (e.g. a database) is roughly in the right ballpark. But if you do micro-benchmarks that really try to stress it, you might see double-digit performance degradation. A number of loads will spend almost all their time in user space, and not see much of an impact at all."
