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 Intel i5-4200U is a dual core 4th generation Haswell processor. Specifically designed for tablets and ultrabooks it gives the appropriate balance between performance and battery life. The i5-4200U has integrated HD 4400 graphics which are fine for desktop use but not suited to 3D gaming. With an impressive TDP of just 15 Watts, the 4200U will typically give 6 hours of battery life. Despite the low effective speed of 56 which is 70% below the average of the leaders, when coupled with an SSD the 4200U can give a reasonable user experience. Comparing the 4200U and 4500U shows that the 4500U has 20% faster single-core performance but also costs 40% more. [Nov '14 CPUPro]
