AMD Ryzen 7000 “Zen 4” CPU Delay confirmed!

BIOS issues to be blamed

AMD’s Ryzen 7000 “Zen 4” CPU and the respective AM5 platform are encountering some severe turbulences ahead of launch. Numerous rumors have sprung up prior to the 29th August unveil which claim the chips will most certainly face some (short) delay.

AMD Ryzen 7000 “Zen 4” Desktop CPUs & AM5 Platform Faces Delay As BIOS Issues Mount Up

Despite AMD confirming it will be hosting the official unveiling on the 29th of August, the actual sales won’t open up for a few weeks or even a month later. Earlier WCCFTech had reported in their own exclusive that the launch might be postponed to the 27th of September, the same day as Intel’s 13th Gen Raptor Lake CPU unveil.

Tech insiders and actual reviewers are now confirming that the launch has indeed been delayed and AMD has asked to sign a new NDA, more or less confirming the new launch date.

The following was published by nApoleon, Chiphell’s resident tech reviewer and editor in the forums:

To clarify, the 19th of August will be the Ryzen 7000 official “Unveil”. The product launch itself was scheduled to be on the 15th of September, but that is now been move to be on the 27th of September.
We already know that the reason behind this delay is linked to the BIOS which is a central part to the new CPU functionalities and performance improvements.

So far, there have been at least 7 AGESA BIOS revisions in total, starting with Patch A to Patch G. The latest BIOS was issued this month and things aren’t going smooth with that one either.

Gigabyte has listed the AGESA Patch D (older BIOS) for its X670E AORUS Master motherboard.

Previously, it was expected that the motherboard vendors will release AGESA BIOS v1.0.0.1 Patch D with their motherboards on launch but that doesn’t seem to be the case anymore since the older BIOS is not optimized enough for AMD Ryzen 7000 CPUs and the AM5 motherboard platform which also supports EXPO DDR5 memory. As such, there are reports that the official BIOS at launch would be v1.0.0.2 and we will also see future revisions of the BIOS moving forward.

For those wondering what these BIOS issues are related to, there are several revisions, with each focusing on various optimizations, fixes, and support. The current SMU has been updated to 84.73 and supports AMD Ryzen 7000 16-core and 12-core CPUs while the previous one added better OC capabilities for DDR5 memory.


The list goes on but it’s not specific to just memory or the CPUs. As mentioned earlier, the AGESA BIOS firmware will be updated on a priority basis prior to and after the launch of the AM5 platform so rather than having sales commence now and have users go through a cumbersome BIOS update process, AMD rescheduled the launch to a later date for a smoother and better first-time experience for users on their next-gen platform.
