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]

AMD’s Ryzen 5 3600 is one of five new processors based on the latest Zen 2 7nm microarchitecture. Although the 3600 is at the bottom of the 3000 line-up, it is no less innocuous to the competition. This 6-core, 12-threaded processor is expected to be priced at 199 USD and succeeds the Zen+ Ryzen 5 2600 improving upon it by 20% in terms of effective speed. In fact the 3600 base and boost clocks of 3.6 Ghz and 4.2 GHz respectively, match the previous generation hex-core Ryzen 5 2600X and therefore indicate an 11% clock for clock improvement over the previous generation. At this price point, the Ryzen 5 3600 only has to compete with Intel’s 6-core i5-9400. Whilst single and quad core speeds are comparable, AMD continues to excel at multi-core performance, with early benchmarks showing a 63% multi core advantage over the 9400. If that was not enough to tempt Intel loyalists to defect, the Ryzen 3000 processors all include coolers and although they will be launched alongside the new mainstream X570 chipset (which is PCIe 4.0 enabled), they are backwards compatible with 400 and even the 300 series motherboards. [Jun '19 CPUPro]
