Intel’s i3-8100 from their 8th generation of Core processors is a mainstream quad-core CPU. It is the entry model of the latest Coffee Lake line up with a clock speed of 3.6 GHz. Previously, i3 Kaby Lake processors had two cores with hyperthreading, but now, i3 Coffee Lake processors have 4 cores and offer much better value for money in terms of dollars per core. With a performance profile that closely matches last years mid range Kaby Lake i5's (the then go-to mid range gaming choice) and a price tag of just $120, the i3-8100 represents excellent value for money. Unfortunately, like all Coffe Lake processors, the i3-8100 does require a new 300-series motherboard even though it shares the same LGA1151 socket as the previous generation of Kaby Lake 200 motherboards. Intel were clearly mindful of AMD's similarly priced quad core Ryzen 3 1200 which achieves very comparable single, and quad-core benchmarks to the i3-8100. ^{[Oct '17 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 a 2060S to a 2070S. 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]}
