The Core i7-6700K is Intel's latest "Skylake" flagship processor. It replaces the hugely successful i7-4790K and takes the crown as the fastest mainstream consumer CPU available. Comparing performance and specs between the 4790K and 6700K shows that the configuration is largely unchanged (same base clocks, cores, threads) but the improved manufacturing process (14nm) brings a small reduction in TDP and a performance improvement of 8%; almost exactly the same jump as between the Ivy Bridge 3770K and Haswell 4770K. Owners of any unlocked-K Intel CPU from Sandy Bridge or onwards still have no real reason to upgrade as the performance improvements are largely academic but the i7-6700K will be the CPU of choice for the vast majority of top end PC builds in 2015. [Aug '15 CPUPro]

The i5-10400F is a six-core hyperthreaded CPU from Intel’s latest Comet Lake series of desktop processors. This 65 W CPU has single core and all core boost frequencies of 4.3 GHz and 4.0 GHz, respectively. Whilst the 10400F will require a new LGA1200 motherboard, such as the Z490, Intel have guaranteed that the next generation of Rocket Lake CPUs will also be compatible with this chipset. The 10400F is aimed at mid-tier gaming PC builds, and as such, ships with a cooler but without integrated graphics. Despite being officially launched in Q2 of 2020, at the time of writing, the 10400F is still not widely available. Compared to the similarly priced Ryzen 5 3600, the 10400F’s lower memory latency gives it the lead in gaming and effective speed benchmarks. Since the Ryzen architecture creates a gaming bottleneck, it is necessary to upgrade to a higher tier, Intel CPU for better gaming performance. On the other hand comparing the i5-10400F and the i3-10100 shows that the 10100 offers comparable gaming performance for 22% less money whilst also including integrated graphics. [Jun '20 CPUPro]
