We know that AMD will be unveiling its next-gen Ryzen 7000 series "Zen 4" processors on August 29, but previous rumors had a launch that was just two weeks later... but then we started hearing about a new, delayed September 27 release.

VideoCardz reported that NDAs were sent out to reviewers, but AMD needed reviewers to re-sign the NDA as the launch of the Ryzen 7000 series "Zen 4" processors had been delayed. In a post on the Chiphell forums, we're hearing that one of the reviewers on Chiphell confirmed that they were told about the updated NDA, and Zen 4 launch being postponed.

The post continues, asking if we remember how long it took for the BIOS issues ot be solved after AMD's current-gen Zen 3 launched. AMD does have its new AM5 socket, has added DDR5 memory and PCIe 5.0 technology support on its new X670E + X670 motherboards, ready for the world of Ryzen 7000 series "Zen 4" CPUs.

That will make for one of the biggest days in technology history: next-gen AMD and Intel CPUs and motherboards... all in the same week? I can't wait.
