It has, but you have to use AVX and other new instruction sets. Singlethreaded, a fifth-gen Core m5 tablet CPU can be as fast as a first-gen Core i Xeon workstation CPU, and a sixth gen i7 desktop CPU can be twice as fast as both: https://admin.tao.at/post/evolution-of-cpu-efficiency/ https://admin.tao.at/post/evolution-of-cpu-efficiency/
(Sadly I don't have any Pentium 4s left to compare on. And of the Core2 generation only laptops.)
- flamedoge 10y agoIt seems like a lot of new tech went into AVX and increasing both width and number of vector registers. Kind of makes you doubt whether single-threaded performance is just a mask for wider execution pipe underneath.
