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]

The 6 core, 12 thread Ryzen 5 2600X is one of four new AMD second generation of high-end desktop Ryzen processors (codenamed Pinnacle Ridge) renowned for excellent value multi-core performance. The 2600X is set to replace the also 6 core, 12 thread 1600X as AMD’s new mid-range Ryzen 5 flagship. The latest generation of CPUs features a matured Zen+ chip architecture with 12nm lithography, increased clock speeds and Precision Boost 2 technology designed to leverage more CPU power than per the first generation. The 2600X appears to have stock base / boost clock speeds of 3.6 / 4.2 GHz. This is only marginally faster than the 1600X’s 3.6 / 4.0 GHz. Modest effective speed improvements are expected, although further benchmarks are necessary to draw firm conclusions. The 2600X ships with a Wraith Spire cooler and is priced reasonably at an expected $250. However, for most use cases, the new lower clocked Ryzen 5 2600 at $200 represents better value for money. Pinnacle Ridge processors are designed to work with the new 400 series motherboards, which allow for greater overclocking head room, and they are also backwards compatible with the 300 series motherboard following a bios update. [Apr '18 CPUPro]
