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 3300X is a 4-core Ryzen CPU. Priced at just $120 USD, it offers far better value to gamers than all the previous Ryzen CPUs. This is great news for potential buyers, but bad luck for gamers that recently spent nearly three times more on the 8-core 3700X. The reduction from eight to four cores results in more efficient caching and higher boost clocks. AMD’s marketing has abruptly broken from the firmly established “moar cores” mantra to a conveniently realistic: four cores are actually okay. Shifting goalposts this quickly reveals an unhealthy focus on first time buyers and a brazen disregard for existing customers. Sales tactics aside, unfortunately the 3300X remains constrained by architectural latency and the associated gaming bottleneck (frame drops). Comparing an overclocked 3300X pegged at 4425 MHz to a stock Intel Core i3-10100 running at 4100 MHz shows that the i3-10100 delivers better gaming performance in four out of five games. The 10100 also includes an iGPU with QuickSync hardware encoding. Since additional cores make little difference to gamers, there are no significant upgrades beyond the 3300X in the Ryzen product stack. In order to achieve better gaming performance, it is necessary to upgrade to a higher tier Intel CPU. Despite the barrage of anonymous hearsay pushed on social media, users will be hard pressed to find actual use cases that favor the 3300X over the i3-10100, especially when the 10100 is not handicapped by 2666 MHz RAM. Gamers are bottlenecked by the Ryzen architecture and desktop users need integrated graphics. [Jun '20 CPUPro]
