The Ryzen 7 3800X is an 8-core, 16-thread high end desktop Zen 2 processor, built on AMD’s seminal 7nm manufacturing process. It has a boost clock speed of 4.5 GHz, overtaking the previous Zen+ flagship, the Ryzen 7 2700X, by 200 MHz and around 16% in terms of effective speed. The 3800X is available at launch for $399 USD alongside four other new Zen 2 processors, including the similarly specified Ryzen 7 3700X. The main differences between the 3800X and 3700X being an extra 100 MHz of boost clock frequency on the 3800X and extra TDP headroom (105W for the 3800X versus 65W for the 3700X) for a $70 USD premium. The 21% higher release price translates to just a 2% higher effective speed over the 3700X. The 3800X is in direct competition with Intel’s i7-9700K, benchmarks show that, when overclocked, the 3800X is 10% worse for gaming but 30% faster for 64-core processing. The 3800X is also 15% ($50 USD) more expensive than the i7-9700K. Additionally, the 3800X's memory controller, although significantly improved over previous Ryzen iterations, still has limited bandwidth and high latency which can also impact gaming. Like the other third generation Ryzen processors, the 3800X is compatible with the new PCIe 4.0 enabled X570 chipset as well as the 400 and 300 series motherboards. At $380 USD, the 3800X offers reasonable value for purely workstation tasks such as film production but streamers should look elsewhere. Streaming with dedicated hardware such as NVENC or a separate stream PC will nearly always result in fewer dropped frames. ^{[Jul '19 CPUPro]}

The i5-8400 is a competitively priced hex-core processor from Intel’s 8th generation of Core processors (Coffee Lake). Along with the release of the unlocked i5-8600K, this is the first time that six-core processors have featured in the i5 line-up. Like the other Coffee Lake processors, the i5-8400 is based upon an improved version of Intel’s 14nm architecture which featured in both Skylake and Kaby Lake. Early benchmarks reveal that for average quad core usage (most games employ a maximum of four cores) the i5-8400 performs way above its pay grade. It achieves quad core mixed speeds close to Intel’s outgoing 2017 flagship the $300, quad-core, 8 thread i7-7700k, which to date has been a strong favourite for high-end gaming setups. On paper, the i5-8400 has a base clock of 2.8 GHz (Intel are significantly downplaying the performance of this SKU by giving it a relatively low nominal base clock), an all core boost of 3.8 GHz (this is the effective base clock figure that counts) and a single core boost of 4 GHz. This compares reasonably well to the i5-8600K which has a base clock of 3.6 GHz, all core boost of 4.1 GHz and a single core boost of 4.3 GHz. The i5-8400 also features 9MB of L3 cache and an energy-thrifty TDP of 65W. Priced at under $190, the i5-8400 offers fantastic value for money. Unfortunately, like the other Coffee Lake processors, the i5-8400 will require a new 300 series motherboard, and at the time of writing, the only available version is Intel’s high-end Z370 which isn't an ideal pairing for the i5-8400. The Z series motherboards are designed to cater for the unlocked and overclockable "K" SKUs. Cheaper 300 series motherboards will be available in 2018 at which time the 8400 will offer even better value for money. ^{[Oct '17 CPUPro]}
