AMD released the FX-9590 back in July 2013 but it's not until recently that these processors have started hitting the shelves and even now prices are still extremely high. This is the first mainstream 5GHz processor but clock speed isn't the key performance indicator it once was. Comparing the 9590 to the 8350 shows that the 9590 has 16% better overall performance which is almost exactly in line with its base clock increase from 4.0 to 4.7 GHz. Despite this performance boost the 9590 still lags Intel's most recent 4770K Haswell processor by 26% and that's despite the AMD's 27% higher base clock. In terms of relative performance the AMD's strong point is Integer processing where it has 8 processing units vs just four (one per core) in the 4770K. Overall, especially at current prices, the 9590 doesn't represent good value for money. [Jan '14CPUPro]
The FX-9370 is the slightly lower clocked (4.4 GHz) version of AMD's flagship FX-9 range of desktop processors. The FX-9590 comes clocked at 4.7 GHz with a staggering turbo clock of 5 GHz. Comparing the 9370 and 9590 versions shows that there is only 3% between the two processors at stock clocks but when overclocked they both have an identical performance profile. Given that the 9590 costs nearly 25% more the 9370 should be the obvious choice. Both of these processors have superb multi-core performance but they both lag Intel when it comes to single and dual-core workloads. Until AMD can improve single core performance they will continue to struggle in the high end PC market. [Mar '14CPUPro]
