AMD's RDNA 4 high-end GPU with 32GB memory expected to launch by mid-2025.

AMD may be developing an RDNA 4 graphics card equipped with up to 32GB of VRAM, potentially arriving in the first half of 2025. According to a source on Chiphell (as noticed by TechSpot), this high-end RDNA 4 GPU could be an RX 9070 XT variant with doubled-up VRAM to 32GB, though AMD seemingly hasn't made a final decision on that specification. While this would technically make it a gaming graphics card rather than a professional Radeon Pro product, the source claims the GPU is "still set to primarily target the AI market, and will be priced as such," meaning "the value proposition will not make much sense for gamers."

The speculation should be regarded with considerable skepticism. AMD has already indicated in "reasonably clear terms that it won't be running with anything more than mid-range graphics cards with RDNA 4 - although a high-end offering has never been completely ruled out." If a high-end Radeon GPU like an RX 9090 XTX was genuinely in development, it would likely have surfaced through the rumor mill by now, particularly given that the rumored launch window is in the next few months. The most sensible conclusion is that this is "likely to be a heavyweight GPU targeted at the likes of AI usage, not a gaming card."

The source originates from the Chinese forum Chiphell, where such rumors should be "regarded with more skepticism than normal" given the volume of speculation there, though some claims from the forum's users have proven accurate. A high-end gaming GPU arriving in the next few months would certainly be shocking given what AMD has publicly stated about RDNA 4's positioning.

Looking further ahead, gamers may have better prospects with AMD's next generation architecture. AMD is rumored to be unifying RDNA and CDNA with the next generation, likely to be called UDNA rather than RDNA 5, which "would make sense as a clean slate on which to return to the higher-end of the gaming GPU spectrum." Current speculation suggests that a potential UDNA flagship graphics card "won't beat the RTX 5090, though (but perhaps equalling NVIDIA's Blackwell top dog)," though such a release remains far in the distance.
