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 16 core, 32 thread Ryzen Threadripper 1950X is finally here to seize the throne for high end desktop processors. The 1950X is the flagship of the Zen based Threadripper series which also includes the 12 core 1920X and the 8 core 1900X. The 1950X has a stock clock of 3.4 GHz increasing to a maximum single core boost of 4.0 GHz and features quad channel DDR4 and 64 PCI Express lanes. This processor is effectively two Ryzen 7 1800Xs glued together with Infinity Fabric (AMD’s scalable interconnecting technology), making the 1950X one of the physically largest CPUs on the consumer market. If you are considering this CPU, you will need a new X399 motherboard with a TR4 socket. Early benchmarks show the 1950X competing with Intel’s similarly priced i9-7900X. Whilst the 7900X has slightly higher single and quad core scores (10%-15%), the 1950X is around 35% faster for multi-core workloads. Content creators, and other core intensive task masters will not be disappointed. [Aug '17 CPUPro]
