Update | RTX 5090 beware: AMD reportedly working on an RDNA 4 GPU with 32 GB VRAM

February 13, 2025 7:42 PM GMT update: AMD's Frank Azor has denied the existence of a 32 GB RX 9070 XT variant via a new X post. That said, it is common for OEMs to not acknowledge unreleased products, and there's still a chance it could launch later this year.

Original post:

So far, AMD's promotional material suggests the Radeon RX 9070 XT will be top-spec RDNA 4 GPU this generation with 16 GB of VRAM. A higher-end card with a Navi 4c GPU was scrapped for a myriad of reasons. But, Team Red still has yet another trick up its sleeve, if a rumour from Chiphell is accurate.

Apparently, the company plans to launch another high-end RDNA 4 GPU sometime in H1, 2025. While the VRAM capacity hasn't been decided, it could be as high as 32 GB. Essentially, this will act as AMD's RTX 5090 counter this generation. But there is some doubt if this is a gaming GPU or one for data centres, which could legitimately benefit from the extra video memory. And, it will probably cost a pretty penny unlike the RX 9070 XT.

32 GB of VRAM implies the GPU memory bus will be either 256-bit or 512-bit. There has been no information about AMD working on a GPU with latter. Hence, there's a good chance it could be a higher binned Navi 48 GPU with some AI chops thrown on top. But, if it launches under the Radeon branding, you might be able to play some games on it. Not very well, but still.
