The Intel i9-9900K is an 8 core, 16 thread, unlocked 9th generation Coffee Lake processor. It has a base / boost clocks of 3.6 / 4.7 GHz and a single-core boost of 5.0 GHz (the highest frequency achieved yet from this class of Intel CPU). It features 16 MB of cache, a 95W TDP and Intel UHD 630 graphics. The 9900K is compatible with the new Z390 chipset, and subject to a BIOS update, is also compatible with the older Z370 chipset. Aimed at users who do not wish to compromise, the i9-9900K offers the best gaming and desktop experience available at any price. Heavy workstation users should consider the Ryzen 9 3900X which is similarly priced. Comparing the overclocked 3900X shows that it is just 10% worse for gaming and desktop (sub octa-core) but around 40% better for 64-core computations. Gamers should consider the 9700K which offers identical overclocked gaming performance at a $100 USD discount. [Oct '18 CPUPro]

MORE DETAILS

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]
