AMD’s upcoming RDNA 5 / UDNA GPUs are set to feature a significant boost in compute units, with the flagship die potentially sporting up to 96 compute units, a 50% increase over the top RDNA 4 GPU’s 64 compute units. Leaker Kepler_L2 has hinted at several potential configurations for the next-gen architecture, including three distinct die options:
- Navi 5X (Top): 96 CUs + 384-bit memory bus
- Navi 5X (Mid): 64 CUs + 256-bit memory bus
- Navi 5X (Low): 32 CUs + 128-bit memory bus
For the flagship model, the RDNA 5 GPU could feature a 384-bit memory bus, leading to higher memory capacities and potentially denser VRAM modules, which could offer unprecedented amounts of VRAM. The performance of AMD’s current Radeon RX 9070 XT, which is already close to matching the RTX 5080 with its 64 CUs, suggests that the next-gen 96 CU die could deliver even better performance, potentially rivaling or surpassing NVIDIA’s next 80-tier GPU. While not aimed at the ultra-enthusiast or NVIDIA 90-class market, the RDNA 5 will offer great value for enthusiasts.
Looking at the mid-tier model, the 64 CU die with a 256-bit memory bus is similar to the 9070 XT’s configuration but will feature updated CUs, RT cores, and AI engines for a significant performance boost. The entry-level 32 CU die with a 128-bit memory bus might raise concerns, especially with the 2026-2027 timeline, but denser VRAM modules will likely be available, addressing the 8GB VRAM dilemma for entry-level cards.
While these configurations are still speculative, the RDNA 5 / UDNA lineup is expected to enter mass production by Q2 2026, around the same time as NVIDIA’s “SUPER” series and Intel’s BMG-G31 “Big Battlemage” GPUs. The early months of 2026 will be a thrilling time for PC gamers, with major players in the GPU market releasing their new offerings.
