Spectre mitigations murder userspace performance
I’ve made similar comments in the past but I think we’re just trying to predict too much about what programs are trying to do in hardware.<p>I’d rather have simple hardware that is light on energy requirements and easier to understand. I don’t think software as an industry really has a “this chip isn’t fast enough problem”. Most of the real slowdowns anyone has in day to day performance has more to do with inefficient code than hardware anyways.<p>Look at old game consoles (like a regular old PlayStation) and what they were able to render on what today would be laughably slow hardware. They could do it because developers learned the stack inside and out.<p>I’m hopeful that the emergence of arm as a desktop/server competitor will help in some ways by putting enough pressure on companies like intel to really rethink some of their core stuff, but who knows.
