This is yet another processor from Intel that demonstrates their total market domination in the high end PC sector. The 4820K isn't really a step forward in any particular direction but rather a variant on what's already been available (performance wise) for a few years. As long as Intel is largely competing with itself they will likely continue with these sorts of incremental releases. The 4820K requires an Intel X79 chipset, which dates back to Sandy Bridge-E and lacks some of the newer features like native USB 3.0 support. An investment in the 4820K only makes sense if you already own an LGA2011 Motherboard and could be seen as good money chasing bad given that the platform is due an upgrade. That said the 4820K is a very capable multi-core processor and it sits amongst the top handful of processors in this regard. For typical consumers a Haswell i3 will offer mostly identical response times, a lower energy footprint and a significantly more competitive price. [Nov '13 CPUPro]

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]
