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]

The AMD FX-8150 is the earliest eight core variant in AMD's flagship FX series. The FX-8150 was released in October 2011 and at that time it superseded the Phenom 1100T. Comparing the 1100T and FX-8150 shows that the newer FX-8150 has roughly the same single and dual core speed but, thanks to its extra two cores, pulled ahead of its predecessor by 15% in multi-core tests. The performance improvements over the 1100T are accompanied by an improved manufacturing process which reduced lithography from 45 to 32 nanometres; consequently both processors have the same maximum TDP of 125 Watts. Thanks to its eight cores the FX-8150 has strong multi-core performance but its single-core core speeds are still relatively weak compared to similarly priced Intel chips. [Mar '14 CPUPro]
