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 2600, from AMD’s second generation (Zen+) of high-end desktop Ryzen processors, supersedes the first generation Ryzen 5 1600. The newer generation sees a lithography reduction from 14nm to 12nm, but no increase in the number of cores and threads (6 and 12 respectively) over the ground-breaking first generation which continues to surpass similarly priced Intel CPUs in terms of multi-core performance. In other words, progress between generations is predominantly driven by power efficiency and therefore higher attainable clock speeds. The 2600 appears to have a stock base/boost clock of 3.4 / 3.9 GHz compared to the 1600’s 3.2 / 3.6 GHz which is expected to result in a modest increase in effective speed that said, early benchmarks are inconclusive. Included in the expected retail price of about $200 is a Wraith Stealth cooler, so the 2600, like the 1600 before it, represents great value for money, especially for workstation users. The 2600 compliments the new 400 series motherboards and is also backwards compatible with the 300 series following a bios update. [Apr '18 CPUPro]
