Intel’s 16-core flagship Alder Lake i9-12900K processor delivers a staggering performance improvement over it's predecessor (+70% 64-core). It features a new hybrid architecture which combines eight hyper-threaded performance cores with eight efficiency cores for a total of 24 threads. Alder Lake CPUs will require a new Z690 chipset which supports DDR5 memory and PCIe 5.0. At an MRSP of $590 USD, the i9-12900K is aimed at power users who demand the best of the best. That said, Intel’s 10-core 12600K matches the 12900K’s performance for the majority of consumer use cases at a 50% price discount. [Nov '21 CPUPro]

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 products. 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. [Apr '23 CPUPro]
