In a new post by Chiphell member ZhanZhanHao, AMD's flagship RDNA 5 gaming GPUs would feature up to 128 cores per compute unit, which is a huge upgrade (double) over the current flagship RDNA 4 GPU inside of the Radeon RX 9700 XTX which has 64 CUs.

AMD is expected to launch at least four different GPU die configurations for RDNA 5 according to leaks, in both the gaming-focused Radeon RX series and workstation-based Radeon PRO series GPUs. We should expect the higher-end RDNA 5 die with 96 CUs (12,288 cores), while the mid-tier card would sport 40 CUs, low-end die with 24 CUs, and the entry-level die with 12 CUs. Here's how the RDNA 5 stack would look:

• RDNA 5 high-end die: 96 CUs (12,288 cores)
• RDNA 5 mid-range die: 40 CUs (5120 cores)
• RDNA 5 low-end die: 24 CUs (3072 cores)
• RDNA 5 entry-level die: 12 CUs (1536 cores)

In recent rumors, we've heard that AMD's next-gen RDNA 5 cards would feature LPDDR6 laptop memory, which would be an interesting choice given that NVIDIA has rolled out its GeForce RTX 50 series "Blackwell" GPUs with GDDR7. However, from an economic perspective, LPDDR6 memory is much cheaper than GDDR7, and would usher in next-gen RDNA 5 cards at cheaper price points (if those rumors are correct).

In other rumors, we heard that AMD's next-gen Radeon RX series "RDNA 5" GPUs would feature up to 36GB of GDDR7 and would be an "RTX 6090 killer" with more on that in the links above.
