It's also funny that on Linux, with fully open benchmarks on phoronix, the AMD chips trade blows with the Intel ones and the top end ones of each are actually pretty close, with AMD being a bit slower on average than the top intel ones, but not far off.
For liberal amounts of "pretty close", sure. One of the things to remember is that AMD's CPU's are now several process shrinks behind Intels latest, so its not a surprise that they could be significantly behind in performance. What is surprising is that they are not, and this tells us exactly what Intel is doing. Intel is not throwing most of the advantage of the process shrinks into performance. What they are doing is throwing those advantages into efficiency (power/heat) because the guerrilla in the room is the ARM designs that are dominating much larger markets than the desktop market and doing it with the same process size as AMD is using.
Intel isn't afraid of ARM, but they are afraid that the foundries that are running 24/7 making ARM designs will put together enough money to jump several process sizes which is a danger to what Intel really is, which is a foundry company.
