AMD has announced that its upcoming RX 9070 series (RDNA 4) GPUs will require a UEFI system for optimal compatibility. Put simply, it has dropped support for the older BIOS and CSM standards, requiring users to make the necessary shift to UEFI. While this doesn’t mean RDNA 4 GPUs will cease to function with legacy firmware, AMD offers no assurance.

      All graphics cards interface with BIOS/UEFI when the system initializes - every piece of non-hotswap hardware has to or it won’t be initialized and cannot be used.

      The question is really why should a graphics card maker care to dedicate time to make their card compatible with BIOS when 99.999% of the systems running their cards will use UEFI, and they said ‘hey actually we don’t care’ as far back as 2023 in the 7000 series but for some reason (clickbait) this is being dug up again.

        I mean, yes, but that’s the Bios/uefi asking “what type of hardware are you, what are your capabilities, etc” and not the other way around.
