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 a 6-core, 12-threaded processor which succeeds the Ryzen 5 2600 improving upon it by 13% in terms of overclocked performance. The 3600 is in competition with Intel’s 6-core i5-9600K. AMD continues to push the multi-core performance envelope: benchmarks show that the 3600 has a 27% overclocked 64-core lead over the 9600K but that the i5-9600K leads by 14% on single to hex core workloads which translates to 10% higher EFps in most of the today’s top games (e.g. PUBG, GTAV and CSGO). Additionally, the 3600's memory controller, although significantly improved over previous Ryzen iterations, still has limited bandwidth and high latency which adversely impacts gaming. Weaknesses in memory architecture are not readily picked up by CPU benchmarks but they are apparent whilst gaming. Cheaper CPUs such as the 9400F deliver better gaming performance in nearly all of today’s popular games. At $190 USD, the 3600 offers good value for purely workstation tasks such as film production but streamers should look elsewhere. Streaming with dedicated hardware such as NVENC or a separate stream PC will nearly always result in fewer dropped frames. The masterfully hyped Ryzen 3600 may well be the best CPU for multimedia producers on a tight budget but in today's market there are faster and less expensive alternatives for gamers, streamers and general desktop users. [Jun '19 CPUPro]
