AMD Confirms B2 Ryzen 5000 Stepping Brings No Performance Improvements

AMD has recently confirmed that the upcoming B2 stepping for Ryzen 5000 processors will only improve production and availability with no impact on performance. The new stepping will be deployed within the next 6 months and will be fully compatible with existing motherboards without the need for a BIOS update. We initially believed that the new revisions may bring small performance improvements similar to existing Ryzen XT products however with this recent confirmation from AMD we now know that this is not the case. AMD has not confirmed if they are preparing a potential Ryzen 5000XT series which would likely be the final release on the AM4 platform.
AMDAs part of our continued effort to expand our manufacturing and logistics capabilities, AMD will gradually move AMD Ryzen 5000 Series Desktop Processors to B2 Revision over the next 6 months. The revision does not bring improvements in terms of functionality or performance, furthermore, no BIOS update will be required.

watzupkenAlder Lake may likely result in improved single core performance, but multicore performance is not going to catch up with Zen 3 when their top SKU is expected to only have 8 performance cores with 8 efficient cores.
Well multi-threaded performance is going up by 100% over Skylake, if you can believe the Intel sources talking to guys like Moore's Law is Dead. Single thread IPC is 19% uplift

damricRemember the C3 Phenom II also did not bring a performance improvement, same stock clocks.

But oh boy they overclocked so much better than C2.
Very good point. Probably this time it's the same kind of thing.

tabascosauzOh, I don't doubt that AMD makes behind the scene changes. The previous gens didn't outwardly advertise multiple steppings, and Matisse went from 3.9@1.3V to 4.5@1.25V on the original stepping. Just curious that AMD's choosing to do this now on Vermeer, had to be something at least somewhat worth noting.
Reminds me of the socket 462 days, when a 04xx T'bred 2400+ KIXJB OC'ed better than a 03xx T'bred 2400+ AIUHB, IIRC.

Wonder if it's a silent actual-proper-USB-stability-fix stepping instead of the current AGESA fix lottery (completely resolves issue for some, mitigates but remains intermittent for others, or doesn't help at all).

theGryphonFar from it.
It's been a new process node for AMD (and TSMC for that matter) and a new core, so process improvements to reduce defects and increase yield, along with some bugfixing are all expected.
Maybe lack of competition from Alder Late did not force their hand to eek out minor performance increases (at the expense of power/temps) or maybe the manufacturing process just didn't have it in it. In any case, it's a win for the consumer if thanks to this stepping availability will increase at/below MSRP and system stability will improve.
we have no competition RN so lets just up the prices and slow the releases of new and improved SKU's...
sounds just like intel tbh

This is BS talk. What release are they slowing down, or delaying?

5000 series prices went above MSRP because of supply issues.

Other than that, of course they will try to milk it as much as they can with a product. That's just being business. Has nothing to do with "being like INTEL".

Plus, who said increased prices?? For all we know, this is a stepping progression. Meaning, most likely these will replace existing products. For all we know, they will come at same price points, with higher availability.

People start assuming, then talking BS based on their on assumptions. Sheesh...
