AMD slyly reveals Radeon RX 7800M official with 12 GB VRAM

[Redaktion]

AMD has stealthily announced a new laptop GPU, the AMD Radeon RX 7800M. It features 12 GB VRAM, a Navi 32 GPU, 60 CUs and a max TDP of up to 180 Watts.

It would be nice if they actually appeared in products. The 7900M is nowhere to be seen.

Hopefully saving the trouble for some of you: if you intend on using the GPU with ROCm (ML or what have you) and you don't author all your code yourself, steer clear of this GPU. 1st party support doesn't list mobile GPUs whatsoever; even if you stretch the list of support based on graphics IP family (which may or may not mean anything when you file bugs/issues) on Linux is limited to Radeon 7900 series (gfx1100), gfx1032 is only supported in the PRO series anymore and on Windows you don't get library support with gfx1032, so you have to build all the libraries yourself (and don't get support if BLAS gives you wrong results).

On the internet you will see things like "it works, don't worry", which in 99% of the cases is true, that's why it's mindboggling that there's no official support. What's also 99% sure is that new features won't ever get backported to HW, such as WSL2 support which again is exclusive to gfx1100.

7900M would be a different thing, that being Navi31 so sharing the same die as desktop 7900 GRE and getting the same support, but even then support is listed for a limited set of SKUs, not a generic statement such as "all gfx1100". BTW, should you want to cross-check whether the product page lists support for ROCm, AMD does you a favor and doesn't confuse you with potentially conflicting information, because the product pages no longer lists supported APIs neither for 7800M or 7800 XT alike. (And believe it or not, this is a step forward from previous state of affairs, truly.)

Wow... That is underwhelming.
