Anandtech published AMD Ryzen 3000 Post-Review BIOS Update Recap: Larger ST Gains, Some Gains, Some Losses A quote from the article:

It’s been a long two weeks following our AMD-review-athon weekend, culminating 7/7 with our extensive coverage of the new Ryzen 3000 series CPUs, the new Radeon RX 5700 series Navi GPUs, as well as our complete overview of X570 chipset based motherboards.

Among the things that didn’t go quite as planned for in the hectic period leading up to Sunday was the matter of launch BIOSes. Always a thorny issue with new platform launches – BIOSes are often under intensive development right up until a new platform ships – we ended up in a situation where some boards had multiple BIOS versions floating around, with performance differences among them. And, while Moores Law may be dead, Murphys Law is alive and well, so of course the BIOS we ended up doing our initial Ryzen 3000 testing on was not the best BIOS for the platform.

So, we want to clarify the timeline of events for how we initially tested, what we’ve re-tested, and if and how the new BIOS behavior might change our original conclusion of the Ryzen 3000 series.
