Apparent revisions of some of AMD’s Zen 3 Vermeer chips have appeared on the controversial UserBenchmark site, with the potential for a serious upset in the works. The B2 stepping SKU of the Ryzen 9 5900X raced through the core tests to produce an average bench that would break into the Intel-dominated top 10 rankings if more samples had been benched.

Few sites are accused of Intel bias as much as UserBenchmark, and it is hardly surprising the benchmark has this reputation when the top 18 places in its current average bench chart are occupied by Intel processors (even the i5-11600 benches higher than the Ryzen 5950X here). There have been signs of a B2 stepping revision of some Zen 3 Vermeer chips for a few months and now APISAK has spotted updated variants of the Ryzen 9 5900, Ryzen 9 5900X, and Ryzen 9 5950X on UserBenchmark. The records for the Ryzen 9 5900 are a few months old, but the latter two chips have new entries. While the 16-core Ryzen 9 5950X (B2) chip didn’t really perform well this time around, the Ryzen 9 5900X (B2) has really rocked the boat.

The B2 stepping version of the Ryzen 9 5900 has a strong average bench of 103% at the moment based on two samples. This score would place it in a reasonable 14th place; but the Ryzen 9 5950X (B2) struggles at 96% based on three samples, with an average turbo rate reaching 4.5 GHz (up to 5 GHz has been suggested for a potential Ryzen 9 5950XT model). However, the single sample of the Ryzen 9 5900X (B2) racks up enough core-testing points to achieve an average bench of 106%, which would give it 8th place in the UserBenchmark chart, ahead of Intel's Rocket Lake chips but still behind the Alder Lake collection. An AMD processor achieving a relatively high position in UserBenchmark’s tables would be quite the upset.

A release schedule of Q4 2021 is also listed, and this has been further corroborated in the past by known leaker Greymon55. The tipster recently claimed that Zen 3 B2 has already been shipped and should be ready for purchase by December. While the B2 revision might simply be a change in the manufacturing process, there are hopes for performance enhancements, including the previously mentioned clock rate boost for the Ryzen 9 processors. It’s possible these high-end Vermeer parts will also be joined by a B2 revision of the AMD Ryzen 5 5600X, which could be redesignated as the Ryzen 5 5600XT. Further refinements could result in Vermeer B2 chips peppering the higher ranks of UserBenchmark, arguably giving the site some much-needed credibility with AMD fans.
