I always thought that higher frequency is better and more cores helps with media encoding, but from what I have heard the Intel Core i5-2500K 3.3GHz quad core is better than the AMD FX-8150 3.6GHz 8-Core at everything but media encoding. http://www.anandtech.com/show/4955/the-bulldozer-review-amd-fx8150-tested/8http://www.anandtech.com/show/4955/the-bulldozer-review-amd-fx8150-tested/7
My question is, why is the Bulldozer worse if it has a higher frequency?
1) Sandy bridge does more work per clock cycle.
2) Bulldozer cores are not truly 8 independent cores, each pair shares resources which hurts in some types of workloads.
3) A "K" chip can be overclocked. A 2500K will happily spend it's life at 4.5 or better.
