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 Ryzen 5 1600 is one of four new Ryzen 5 processors released this month. Based on the AMD Zen architecture, which is comparable to Intel in terms of IPC, the Ryzen 5 1600 has six cores which is more than the vast majority of games are able to use (most games cannot use more than four cores). Ryzen 5 CPUs offer gamers better value for money than the eight core Ryzen 7 models released last month. With six cores the 1600 is approximately 75% better at multi-threaded tasks than Intel's quad core i5 flagship – the similarly priced i5-7600K, the 1600 however, has 25% lower single and 33% lower quad core scores. The 1600 has stock base/boost clock speeds of 3.2/3.6 GHz and its price tag of $219 includes a cooler. Assuming a modest overclock of 10% brings the 1600 within striking range of the 1600X which is the Ryzen 5 flagship. The 1600X sports stock base/boost clocks of 3.6/4.0 GHz but costs $30 more than the 1600 and ships without a cooler included in the box. The Ryzen 5 1600 is the best value for money six core CPU we have seen to date. [Apr '17 CPUPro]
