Right, even single CPU performance of mainstream Intel chips has more than doubled in 7 years (Nehalem to Skylake).
Many important things which affect performance have been stagnant for a very long time, especially cache size and RAM latency. But there's been steady progress in raw CPU power, coupled with a significant reduction in TDP.
- gpderetta 10y agoDo you have a reference for the doubling? How much does the boost from AVX affect the score? I'm asking because I recently "upgraded" my desktop to a cheap westmere 6 core xeon [1] as in most benchmarks it is competitive with recent i7s. [1] x5670 @3ghz, but should easily overclock well into the 4ghz range. Edit: autocorrect

Note that their usage of the word browser is nothing to do with www browsers.
- gpderetta 10y agoOh, Geekbench which can be 'won' by implementing a single encryption instruction in hardware. Still, even looking at the scores for less broken sub benchmarks, like (possibly) lua and dijkstra show a %50 increase in performance from Westmere to Skylake for the same frequency, which is more than I was expecting. And skylake should potentially clock much higher although I believe the top is currently still 4ghz. Of course for anything that can take advantage AVX2 (or AVX3 for xeons) skylake would smoke the old xeon. edit: reword
