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]

At a list price of just $129, the quad core, Ryzen 3 1300X is a great budget CPU. The Ryzen 3 series is based on AMD's powerful and energy efficient Zen core architecture as already featured in the mainstream Ryzen 5 series and performance Ryzen 7 series, both launched earlier this year. The 1300X is fully unlocked with a stock base clock speed of 3.5 GHz running up to 3.7 GHz for boost and has a TDP of 65W. The 1300X comes with AMD's Wraith Stealth cooler, but significantly, it is devoid of integrated graphics. Although this can be inexpensively rectified, it may be a stumbling block to those at the entry-level of the market. By comparison, Intel's dual core, four thread i3-7350K comes with 630 HD integrated graphics. In terms of effective speed, early benchmarks for the 1300X just pip the 7350K to the post but results in specific games will depend on the extent to which the game is able to use more than two processing cores simultaneously. The 1300X scores around 20% higher on quad-core tests whereas the 7350K scores 16% higher on single-core tests. The Ryzen 1300X has been released alongside the similar Ryzen 3 1200 which is also an unlocked quad-core with slightly lower base / boost clock speeds of 3.1 / 3.4 GHz and a slightly lower price of just $109. [Jul '17 CPUPro]
