The I7-7820X is the second of three new Skylake-X HEDT (high end desktop processors) released by Intel as part of their core X series (the others being the flagship 10-core i9-7900X and the 6-core i7-7800X). The 7820X is an 8-core, 16-thread CPU which will amply satisfy all but the heaviest of multi-threaded use cases. The 7820X requires a relatively expensive X299 (Basin Falls) motherboard, which costs upwards of $250. The 7820X is listed at $599 which is about $200 more than AMD's current flagship 8-core, 16 thread Ryzen 7 1800X. In addition to better IPC, the 7820X is higher clocked with base and max boost clocks of 3.6/4.5 GHz respectively, compared to 3.6G/4.0 GHz for the Ryzen 7 1800X. The additional $200 (50%) buys you around 20% more performance in both single and multi core workloads. Intel have also released several Kabylake-X HEDT CPUs: the 4-thread i5-7640X and the 8-thread i7-7740X and will shortly release of even higher spec Skylake-X processors. It's probably wise to hold off purchasing until the eagerly anticipated 16-core, 32-thread Ryzen Threadripper CPUs are launched later this month. [Jul '17 CPUPro]

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]
