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 Ryzen 5 1400 is the entry-level chip from AMD's latest Ryzen 5 series which is aimed at the mainstream market. The 1400 is a budget quad core, 8 threaded CPU with base/boost clocks of 3.2/3.4 GHz. Like most the other non-X Ryzen CPUs the 1400 comes with a decent cooler included in the box (Wraith Stealth in this case). Modestly priced at $169 the 1400 is in direct competition with Intel's recent Kaby Lake dual core, four threaded i3-7350k which runs at a base clock of 4.2GHz. The 1400's 8 threads allow a near 40% lead in multi-core processing, but for single-core tasks the 7350K is 45% faster. The Ryzen 5 1500X commands a $20 premium and offers a 25% increase in effective speed over the 1400. Although the 1400 only has a base clock of 3.2 GHz it should more or less match the 1500X when overclocked. Provided it is overclocked, the 1400 joins the other non-X Ryzen models in offering the best bang for your buck. Users not keen on overclocking would probably do better to consider the 1500X at this price point. [Apr '17 CPUPro]
