AMD BIOS update to fix TPM security flaws
It's becoming clear what the 1.2.0.3e BIOS update is all about. While initial speculation pointed towards the addition of support for Ryzen 9000G APUs, it seems the immediate focus is elsewhere. New reports suggest these BIOS updates are laying the groundwork for a different kind of Ryzen 9000 series chip, notably without integrated graphics.
The report originates from Chiphell (via HXL), where it's claimed that the current AGESA 1.2.0.3e introduces support for a new Ryzen 9000 CPU series with the integrated GPU disabled. This explains why Strix Point or Grado is not mentioned in the latest microcode updates, as this new chip is still based on the “Granite Ridge” architecture.
One of the chips belonging to this series (Ryzen 9000F) has already been mentioned by MEGAsizeGPU and Wccftech. According to them, the Ryzen 7 9700F is an 8-core CPU, sharing the same core count and underlying structure as the existing Ryzen 7 9700X. As such, it's expected to feature 40MB of L3 cache and a 65W TDP. Clock speeds are TBC, but expect something closely matching the Ryzen 7 9700X.
AMD has already made the AGESA 1.2.0.3e firmware publicly available for AM5 motherboards. Beyond supporting the upcoming CPU series, this update also addresses a recently reported security flaw, AMD-SB-4011, which impacts systems using AMD's Firmware TPM (via VideoCardz). This vulnerability could allow a local attacker to expose data or impair system availability through an out-of-bounds read. Some motherboard manufacturers, like Asus and MSI, have already begun rolling out BIOS updates with the latest AGESA microcode update.
Given the widespread AGESA and BIOS updates from numerous motherboard manufacturers, the launch of the Ryzen 7 9700F seems to be just a few weeks away.
KitGuru says: For those who don't need an iGPU, a Ryzen 9000F CPU could be a good alternative for those looking to jump to the Ryzen 9000 series, assuming you can get them at a lower price.
