AMD Radeon RX 9000 UDNA details leak
AMD’s UDNA GPU architecture will reportedly succeed RDNA 4, powering PlayStation 6 and the RX 9000 series
According to a leak from the leaker Zhangzhonghao (via Wccftech), AMD’s RDNA series of graphical architectures will end with RDNA 4. The future of AMD’s GPU ambitions lies in UDNA. Rumour has it that AMD will use UDNA to power their RX 9000 series GPUs and Sony’s PlayStation 6 console.
Based on this information, AMD has no plans to release a GPU architecture called RDNA 5. UDNA will become AMD’s new graphics architecture for both the gaming and enterprise GPU markets. This combines RDNA and CDNA, creating a unified future for AMD’s graphics hardware.
AMD has already confirmed the existence of UDNA. While the company has not revealed when UDNA will come to market, it has now been claimed that AMD’s first UDNA GPUs are scheduled for mass production in Q2 2026. This new architecture will reportedly simplify GPU development for AMD, and allow consumers and enterprise users to benefit from a unified feature set, at least for the most part.
Below is what Zhangzhonghao had to say about UDNA:
- There is no RDNA 5 codename, UDNA will be RDNA 4’s successor
- AMD’s MI400 and RX 9000 series GPUs will use UDNA. These GPUs will reportedly have a similar ALU design to GCN, AMD’s last unified GPU architecture.
- Sony’s PlayStation 6 will reportedly use UDNA graphics. The console’s CPU reportedly remains undecided, with Zen 4 and Zen 5 being options. Sony’s planned handheld will also use AMD hardware.
- Microsoft is reportedly choosing between AMD and Qualcomm hardware for their upcoming handheld.
- This information comes from the supply chain. No detailed specifications or performance figures are known.
UDNA is a rapid departure from what AMD attempted with RDNA. AMD split its gaming and datacenter GPU architectures when it made sense to do so. Now that AMD has gained a foothold in the data center market, the lack of commonality between its desktop and enterprise GPUs is a problem. Reunifying both GPU architectures will help AMD deliver stronger mainstream GPUs for workstations and productivity use. It also combines AMD’s development resources into a single graphics architecture. Will this be good for gamers? Who knows… The combined architecture approach certainly works for Nvidia, but will UDNA be the step forward that gamers want to see from AMD?
