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.

This is going to be interesting
The diagnostic software environment I use to test graphics card VRAM only boots in legacy mode. TServer and Memtune are both internal AMD Tools that have leaked. So far, older boards that support Legacy / CSM have been the ideal platform as a test bench for graphics card repair.
Probably going to be quite the shakeup in the graphics card repair community’s toolkit if the updated version of Memtune for 9xxx cards ever leaks.
Can someone eli5 why the graphics card cares about UEFI?
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.
I can only think about those performance profile options you have in your BIOS/UEFI menus
Your guess is as good as mine.
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.
UEFI came out in like 2005 and was standard on basically all new PC motherboards from around 2012
Tbh I’m shocked generations before this still had official BIOS support
Imagine buying a PCIE 5 card to use in a crusty old PCIE 3 or 2 board >.>
Would you notice that big of a performance difference from PCIE3? Usually for gaming the bandwidth is nowhere near close enough to being saturated and sure, PCIE5 will have 4x the throughput of PCIE3, but I imagine the performance loss would be more due to the CPU than the PCIE bandwidth.

Huh, the 7000G series already required uefi, surprised it took them this long to require that for their dedicated gpus
