Average Bench: 80.1% (230th of 1439)

Based on 28,524 user benchmarks.  Devices: BFEBFBFF00050654, 0F8BFBFF00050654, , 1FABFBFF00050654, 1F8BFBFF00050654 Model: Intel(R) Core(TM) i7-7820X CPU @ 3.60GHz

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]

Not the ideal price/perf, but gets both gaming and work done with room to spare, make sure to use 3600Mhz Memory and OC your mesh to 3,2Ghz
