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 budget Ryzen 5 2400G is a four core, eight thread APU (accelerated processing unit: combined CPU and GPU) from AMD’s Raven Ridge product line. It has a base clock of 3.6 GHz which boosts to 3.9 GHz. Its RX Vega 11 graphics scores an average bench of 20% which is at the forefront of performance from integrated graphics and is 34% faster than the RX Vega 8 graphics found in the Ryzen 3 2200G (the 2400G’s ultra budget sister APU). The 2400G currently retails at $162 and includes a Wraith Stealth cooler. This puts it in direct competition with Intel’s quad core Coffee Lake i3-8350K at $167, which does have a 26% faster effective speed. However, the 2400G’s integrated graphics are far stronger (137%) than the 8350K’s, making the 2400G a great choice for those looking for an economical multimedia PC or a super budget gaming PC. [Apr '18 CPUPro]
