AMD Ryzen 7000 “Zen 4” Desktop Processors and AM5 Platform Delayed as BIOS Issues Attached
While AMD has confirmed that it will host the official unveiling on August 29th, the actual sales won’t open for a few weeks or even a month later. Earlier we reported in our own exclusive that the launch might be pushed back to September 27th, the same day as the unveiling of the Intel Raptor Lake 13th Gen CPU. Now there are more rumors (I don’t know if it’s appropriate to call them rumors now, considering that these reports come from real reviewers and also several insiders who work closely with motherboard manufacturers who know what’s going on) that the launch has indeed been delayed and AMD has asked to sign a new NDA, pretty much confirming the new release date. The following was posted by nApoleon, Chiphell’s technical reviewer and forum editor: One thing I want to make clear is that the August 29th event will be a “Reveal” and not an actual “Launch” that was always meant to be in September. The launch was previously scheduled for September 15th, but was just recently moved to September 27th. We now know that the main reason behind this delay is BIOS related. Like every Zen generation, the BIOS has been a critical part that sees various revisions for improved CPU and memory support. This time, just like the AM4 platform, there will be several revisions before and after the launch. So far, we have heard that there have been at least 7 revisions of the AGESA 1.0.0.1 BIOS in total, starting from Patch A to Patch G. The latest BIOS was released this month, and things aren’t going smoothly with this one either. Gigabyte has listed AGESA 1.0.0.1 Patch D (older BIOS) for the X670E AORUS Master motherboard. Previously, motherboard vendors were expected to release AGESA BIOS v1.0.0.1 Patch D with their motherboards at launch, but this no longer seems to be the case as the older BIOS is not optimized enough for AMD Ryzen 7000 processors and the AM5 motherboard platform that also supports EXPO DDR5 memory. As such, there are reports that the official BIOS at launch will be v1.0.0.2 and we will also see future BIOS revisions moving forward. For those wondering what these BIOS issues are related to, 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 one added better OC capabilities for DDR5 memory. The list goes on, but it’s not just about memory or CPUs. As mentioned earlier, the AGESA BIOS firmware will be updated in priority before and after the release of the AM5 platform, so instead of sales starting now and users going through a cumbersome BIOS update process, AMD has rescheduled the release to a later date. date for a smoother and better first-time experience for users on their next-generation platform.
