50% Jump! – AMD’s RDNA 5/UDNA flagship may be much bigger than RDNA 4

Leaker expect AMD’s RDNA 5/UDNA flagship to be much bigger than today’s Radeon RX 9070 XT

According to Kepler_L2, a reliable PC hardware leaker, has unveiled their expectation of AMD’s next-generation Radeon GPU lineup. With their upcoming RDNA 5/UDNA architecture, the leaker expects AMD to create a new RX 7900 XTX-style graphics card with 96 Compute Units (CUs) and a 384-bit memory bus. If this is true, AMD’s returning to the ultra-high-end GPU market.

Smaller GPUs with 64 CUs and 32 CUs are expected, with each featuring the same memory bus sizes as their RDNA 4 counterparts. Essentially, AMD is maintaining the same CU counts and memory bus sizes while introducing a new high-end silicon. AMD will continue to focus on delivering per Compute Unit performance gains, with their new 96 CU model giving Nvidia competition in the high-end GPU space.

With RDNA 5/UDNA, AMD are likely to continue focusing on AI and ray tracing performance. However, we should also expect increases in performance for standard, rasterised, and gaming workloads. Furthermore, we expect AMD to deliver higher levels of memory bandwidth by using GDDR7 memory. Remember, AMD’s RDNA 4 GPUs still use GDDR6 memory.

Graphics that will power the next generation of consoles

AMD has been working with Sony PlayStation on “Project Amethyst“. This collaboration has seen both companies work on next-generation GPU hardware and software. This research isn’t just for Sony’s next-generation PlayStation console; AMD can use it for its other GPU chips. As such, AMD’s RDNA 5/UDNA graphics architecture will be used to define the next generation of console and PC graphics.

Sony’s Mark Cerny has personally worked on AMD’s RDNA 5 graphics architecture. Furthermore, AMD will be working with Microsoft on its plans for DirectX. The feature set of AMD’s RDNA 5 graphics architecture will define how games are developed for years to come. This is great news for AMD, especially if their recent engineering efforts yield a significant leap in gaming performance. Sony should know what developers want from GPUs, and they are helping AMD to deliver that.

While AMD’s 96 CU 384-bit GPU will be significantly faster than today’s RX 9070 XT, it is AMD’s architectural changes that will define RDNA 5/UDNA. Can AMD deliver an RDNA 4-like performance leap with RDNA 5/UDNA? Will this be enough to push AMD past Nvidia’s next-generation GPU offerings?
