geekbench scores look impressive because they are very very short bursts to prevent power/thermal throttling on iphones, iphones are able to scale up/down preformance wise very quickly, x86 CPUs less so, so what is really being tested is how fast can a cpu jump from idle to full speed.

Geekbench is not at all a reliable benchmark that tells you anything about real preformance.

Its a total farce to suggest that a CPU with a power budget that is 10x to 20x larger, on a modern process, with modern archtecture is somehow just as fast or slower.
