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]

The AMD Ryzen 7 1700X isn't due for release until next week but two of our users has already submitted benchmarks. Comparing the quad and single core scores from our samples shows a relative 4.3% boost on the single core score so it’s possible that turbo wasn’t fully engaged (12% turbo boost expected). These preliminary results are seriously impressive as they put Zen’s IPC between 0% and 9% below Intel’s Kaby Lake. Even in the worst case scenario these results are still impressive. Comparing Intel’s $1,000 6900K and the 1700X shows that AMD delivers comparable performance for half the price! A shake-up of the CPU market will unfold as Zen rolls out. If Ryzen CPUs can overclock to 4.6+ GHz they will likely dominate the entire market putting a very welcome end to the monotonous tick-tock of recent years. [Feb '17 CPUPro]
