AMD's new RX 9000 GPUs only officially support UEFI systems (www.tomshardware.com)

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.

UEFI has been the norm for well over a decade at this point. If you're trying to run a brand new GPU in a 15+ year-old system, you've already made many mistakes.

Yeah... I was a little confused myself.

Wasn't uefi a must already for windows 10 computers? Atleast for win 11 it is. We are probably talking 10-20% max of global computers that are affected and those also the type of computers that are not generally upgrading to RDNA4.

I believe it's a must for store-bought PCs, but it can be installed on BIOS systems manually

Nope, I've been running Win10 on multiple computers with a BIOS.

Atleast for win 11 it is.

AFAIK, UEFI isn't technically a requirement. However, TPM 2.0 is, and that requires UEFI.

TPM 2.0 does not require UEFI. I have a system here with TPM 2.0 and only legacy boot support. And you can just buy a TPM 2.0 module and connect it with any board, that has a SPI connector.
