The Intel Core i5-6600K is based on the new "Skylake" 14nm manufacturing process. Sporting 4 physical cores with base/turbo clocks of 3.5/3.9 GHz the 6600K and its predecessor, the 4690K share the same basic configuration and disappointingly, offer similar performance. Comparing the 6600K and 6700K shows that the 6700K has faster multi and single core performance. The improved multi core performance is due to Hyperthreading which is the key differentiator for the i7-6700K. The gap in single core performance can largely be eliminated by overclocking the i5-6600K so although the stock effective speed is significantly higher on the 6700K, this gap diminishes significantly when both processors are overclocked. At a 30% discount, the 6600K is the better value gaming CPU. [Aug '15CPUPro]
The 5800X3D has the same core architecture as the 5800X but it runs at 11% lower base and 4% lower boost clocks. The lower clocks are in exchange for an extra 64MB of cache (96MB up from 32MB) and around 40% more money. For most real-world tasks performance is comparable to the 5800X. Cache sensitive scenarios such as low res. canned game benchmarks with a 3090-Ti ($2,000 USD) benefit at the cost of everything else. Be wary of sponsored reviews with cherry picked games that showcase the wins, conveniently 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. Instead of focusing on real-world performance, AMD’s marketers aim to dupe consumers with bankrolled headlines. The same tactics were used with the Radeon 5000 series GPUs. Zen 4 needs to bring substantial IPC improvements for all workloads, rather than overpriced "3D" marketing gimmicks. New PC builders have little reason to look further than the $260 12600K which, at a fraction of the price, offers better all round performance in gaming, desktop and workstation applications. Users with an existing AM4 build should wait just a few more months for better performance at lower prices with Raptor Lake or even Zen 4. The marketers selling expensive “3D” upgrades today will quickly move onto Zen 4 (3D) leaving unfortunate buyers stuck on an overpriced, 6 year old, dead-end, platform. [Mar '22CPUPro]
We calculate effective speed which measures real world performance for typical users. Effective speed is adjusted by current prices to yield a value for money rating. Our calculated values are checked against thousands of individual user ratings. The customizable table below combines these factors to bring you the definitive list of top CPUs. [CPUPro]
