The i5-8400 is a competitively priced hex-core processor from Intel’s 8th generation of Core processors (Coffee Lake). Along with the release of the unlocked i5-8600K, this is the first time that six-core processors have featured in the i5 line-up. Like the other Coffee Lake processors, the i5-8400 is based upon an improved version of Intel’s 14nm architecture which featured in both Skylake and Kaby Lake. Early benchmarks reveal that for average quad core usage (most games employ a maximum of four cores) the i5-8400 performs way above its pay grade. It achieves quad core mixed speeds close to Intel’s outgoing 2017 flagship the $300, quad-core, 8 thread i7-7700k, which to date has been a strong favourite for high-end gaming setups. On paper, the i5-8400 has a base clock of 2.8 GHz (Intel are significantly downplaying the performance of this SKU by giving it a relatively low nominal base clock), an all core boost of 3.8 GHz (this is the effective base clock figure that counts) and a single core boost of 4 GHz. This compares reasonably well to the i5-8600K which has a base clock of 3.6 GHz, all core boost of 4.1 GHz and a single core boost of 4.3 GHz. The i5-8400 also features 9MB of L3 cache and an energy-thrifty TDP of 65W. Priced at under $190, the i5-8400 offers fantastic value for money. Unfortunately, like the other Coffee Lake processors, the i5-8400 will require a new 300 series motherboard, and at the time of writing, the only available version is Intel’s high-end Z370 which isn't an ideal pairing for the i5-8400. The Z series motherboards are designed to cater for the unlocked and overclockable "K" SKUs. Cheaper 300 series motherboards will be available in 2018 at which time the 8400 will offer even better value for money. [Oct '17 CPUPro]

Intel’s tenth gen, six-core i5-10600K is one of the fastest consumer CPUs currently available. Out of the box, its maximum all core frequency is 4.5 GHz, but a simple overclock allows all 12 threads to hit 5.0 GHz. Although a new Z490 (LGA1200) motherboard is required, Intel have indicated that LGA1200 will remain compatible with Rocket Lake CPUs which are due later this year. The eight-core Ryzen 3700X currently competes in the 10600K’s price bracket. CPU based encoding is akin to using hair clippers on a lawn but If dedicated hardware such as NVENC or QuickSync is not an option, the 3700X can outperform the 10600K in encoding workloads such as UserBenchmark 64-core, Cinebench, Blender-CPU and Handbrake-CPU. Meanwhile, the 10600K is better for almost everything else. Currently, the real problem with the 10600K, and much of the Comet Lake line up, is availability. Whilst there was a paper launch in Q2 2020, at the time of writing, the 10600K is still largely unavailable for purchase. In order to achieve better value for money, without compromising on gaming performance, it is necessary to consider the older generation 9600K which is 26% cheaper and offers similar gaming performance. [Jun '20 CPUPro]
