This week there has been talk about a revision of the AMD Ryzen 5000 desktop processors (Vermeer) on the way to deliver faster turbo clocks. It wasnt very clear, but some expected a B2 revision, spotted in the wild, to refine AMDs current offerings in some way or be instrumental in adding faster XT variants to the lineup. Perhaps to stop the gossip getting out of hand, an AMD official provided a statement to Polish tech news site Benchmark.pl, and to Toms Hardware, hopefully stamping out any mi...

In a recently published whitepaper, titled...
