AMDs Ryzen 7000 “Zen 4” Processor and the related AM5 platform doesn’t seem to be going through a smooth launch plan. Before the August 29 announcement, several rumors surfaced indicating that the chips may face a short delay.

AMD Ryzen 7000 “Zen 4” Desktop CPUs and AM5 Platform Experience Lagging As BIOS Issues Increase

with AMD approved It will host the official launch on August 29, the actual sales will not open for a few weeks or even a month. before we reported We privately announced to ourselves that the launch could be delayed to September 27, the day Intel’s 13th Gen Raptor Lake CPU was announced.

Now there are more rumors (I don’t know if it’s even appropriate to call them rumors, considering where these reports came from. real reviewers and also one of the few insiders who are working closely with motherboard manufacturers and are aware of what’s going on) that the launch was indeed delayed and asked AMD to sign a new NDA, more or less confirming the new launch date.

Posted by below nApoleon, Chiphell’s resident technology reviewer and editor on the forums:

One thing I’d like to clarify is that the August 29 event will always be a “Reveal”, not an actual “Launch” that should be in September. this The launch was previously scheduled for September 15. but this was moved to September 27 more recently. We now know that the main reason behind this delay is BIOS related. Like every Zen generation, the BIOS has been a crucial part that has seen several revisions for improved CPU and memory support. This time around, just like the AM4 platform, there will be several pre- and post-launch revisions.

So far, we’ve heard of at least 7 AGESA BIOS revisions in total, from Patch A to Patch G. The latest BIOS was released this month and things are not going well with that either.

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

Previously, motherboard manufacturers were expected to release the AGESA BIOS v1.0.0.1 Patch D with their motherboards at launch, but that doesn’t seem to be the case anymore as the old BIOS is not sufficiently optimized for AMD Ryzen 7000 CPUs. AM5 motherboard platform that also supports EXPO DDR5 memory. Therefore, there are reports that the official BIOS will be v1.0.0.2 when it is released, and we will also see future revisions of the BIOS progress.

For those wondering what these BIOS issues are all about, there are several revisions, 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 SMU added better OC capabilities for DDR5 memory.

The list goes on and on, but it’s not just memory or CPU specific. As previously stated, the AGESA BIOS firmware will be updated prior to and after the AM5 platform launch, so instead of starting sales now and users going through a cumbersome BIOS update process, AMD has rescheduled the launch for later. history for a smoother and better first experience for users on next-gen platforms.
