A 384-bit memory bus and 96 CUs may be features of AMD’s next UDNA/RDNA 5 GPU.

AMD’s next UDNA (or RDNA 5) GPU generation will bring back higher-end GPU configurations with up to 96 Compute Units (CUs) in the top-end Navi 5X SKU, along with a 384-bit bus for memory, according to one of the most trustworthy AMD leakers, Kepler_L2. Although the exact type of memory AMD will eventually use is still unknown, it is possible that GDDR7 will be used. AMD intends a GPU with 64 CUs and a 256-bit memory bus at the middle of the stack, with other CU and memory capacity variations centered around that. AMD might provide a 32 CU setup with a 128-bit memory bus for the entry-level versions. Memory capacity are currently unknown and could alter as AMD completes its GPU portfolio.

A UDNA/RDNA 5 will be a welcome boost to AMD’s campaign for the middle-end market share after the RDNA 4 generation left the company without a top-end competitor. We are eager to see what AMD has created in terms of microarchitectural modifications and what UDNA design may accomplish. Since these GPUs are planned to go into mass production in Q2 2026, availability is projected for the second half of 2026. As launch draws nearer, the precise memory type and capacity will become more apparent.
