The AMD 7000X3D CPUs have the same core architecture as the rest of the 7000 series but they have one group of eight "3D" cores with extra cache. The “3D” cores are priced higher but run at 10% lower clocks. For most real-world tasks performance is comparable to the 7000X variant. Cache sensitive scenarios such as low res. canned game benchmarks with an RTX 4090 ($2,000) benefit at the cost of everything else. Be wary of sponsored reviews with cherry picked games that showcase the wins, ignore frame drops and gloss over the losses. Also watch out for AMD’s army of Neanderthal social media accounts on reddit, forums and youtube, they will be singing their own praises as usual. AMD continue to develop “Advanced Marketing” relationships with select youtubers with the obvious aim of compensating for second tier products with first tier marketing. PC gamers considering a 7000X3D CPU need to work on their critical thinking skills: Influencers are paid handsomely to promote overpriced niche products (X3D, EPYC, Threadripper etc.). Rational gamers have little reason to look further than the $300 13600K which offers comparable real-world gaming and better desktop performance at a fraction of the price. Workstation users (and RTX 4080+ gamers) may find value in higher core CPUs such as the 16-core $400 13700K. Despite offering better performance at lower prices, as long as Intel continues to sample and sponsor marketers that are mostly funded by AMD, they will struggle to win market share. [Mar '23 CPUPro]

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]
