Intel’s Core i5-9400F is a hex-core 9th generation Coffee Lake desktop processor. It features base / boost clocks of 2.9 / 4.1 GHz, 9 MB of cache, a 65W TDP and it ships with a cooler but it does not have integrated graphics like the “non-F” variants. Although the 9400F is compatible with the enthusiast grade Z390 chipset it is normally paired with a better value for money B360 motherboard. At its launch the i5-9400F retailed for $180 but prices have dropped to the point ($135) that it now represents an excellent value proposition to gamers. Comparing the i5-9400F to the Ryzen 3600 shows that the 3600 is 8% better for quad-core processing but it costs 40% ($50) more than the 9400F. Ordinarily higher quad-core performance would result in better gaming but the Ryzen 3000 memory controller, although significantly improved over previous Ryzen iterations, still has limited bandwidth and high latency. Gamers can invest the $50 savings in a better GPU, for example by upgrading from an AMD RX 570 to an RX 580. Since the GPU makes the most difference to gaming, the end result is a system which offers far superior real world gaming performance for similar money. For those gamers who demand the best of the best, it is necessary to jump to one of the higher frequency SKUs such as the 9600K but for everyone else the i5-9400F offers unparalleled value. [Aug '19 CPUPro]

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]
