In terms of raw single-core performance the flagship AMD FX-8350 is lagging behind intel's processor line-up by over two generations. The PassMark Single Thread scores for the i5-2500K vs the FX-8350 are 1863 to 1520 which shows that in terms of raw per-core processing the FX-8350 is lagging the two year old i5 by 23%. Where the AMD FX makes up is on multi-core performance, with a score of 9156 vs 6745, the AMD leads the Intel 2500K by 36% making it the far more capable multi-threaded server orientated performer. The 8350 is also cheaper but significantly more power hungry which counts strongly against it as a server proposition. The FX-8350 could be a good fit for specific server use cases but for general consumer use, which is single and dual core intensive, Intel's two year old i5-2500K delivers better performance.

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]
