In terms of raw single-core performance the flagship AMD FX-8350 is lagging behind intel's processor line-up by over two generations. The PassMark Single Thread scores for the i5-2500K vs the FX-8350 are 1863 to 1520 which shows that in terms of raw per-core processing the FX-8350 is lagging the two year old i5 by 23%. Where the AMD FX makes up is on multi-core performance, with a score of 9156 vs 6745, the AMD leads the Intel 2500K by 36% making it the far more capable multi-threaded server orientated performer. The AMD is also cheaper but significantly more power hungry which counts strongly against it as a sever proposition. The FX-8350 could be a good fit for specific server use cases but for general consumer use, which is single and dual core intensive, Intel's two year old i5-2500K delivers better performance. [May '13 CPUPro]

MORE DETAILS

The AMD FX-8320 has the same architecture and specs as the FX-8350, the only difference being the base/turbo clocks of 3.5/4.0 GHz for the 8320 vs 4.0/4.2 GHz for the 8350. Comparing the two models shows that the 8320 lags the 8350 at stock speeds by around 10% but broadly matches it when both processors are overclocked. This combined with the 8320's considerably lower price tag makes the 8320 the better value proposition. In terms of outright performance, as with all AMD CPUs, the FX series have very strong multi-core performance but lag Intel considerably in terms of single and dual-core throughput. [Mar '14 CPUPro]

Welcome to our desktop CPU comparison. We calculate effective speed which measures real world performance for typical consumers. Effective speed is adjusted by price to yield a value for money rating which is geared towards gamers. Calculated values don't always paint the whole picture so we check them against hundreds of individual user ratings. The customizable table below combines these factors and more to bring you the definitive list of top CPUs. [CPUPro]
