According to Chiphell’s forum member ZhanZhao, AMD’s upcoming RDNA 5 GPUs are expected to feature a total of 128 cores per compute unit. This is a significant increase from the existing RDNA 4 GPUs, which have 64 cores per compute unit.
AMD plans to launch at least four GPU die configurations based on its RDNA 5 graphics architecture within the Radeon and Radeon PRO families. These include:
– A top-tier die with 96 compute units (12,288 cores)
– A mid-tier die with 40 compute units (5,120 cores)
– A low-end die with 24 compute units (3,072 cores)
– An entry-level die with 12 compute units (1,536 cores)
Currently, AMD’s RDNA 4 GPUs come in two dies: the Navi 48 and Navi 44. The top Navi 48 packs up to 64 compute units, scaling down to 48. The Navi 44 is an entry-level SKU with a total of 32 compute units.
AMD made significant changes with its RDNA 4 series market positioning, offering only two dies in a monolithic design for better manufacturing and supply. In contrast, the RDNA 5 architecture will double the core count of Navi 31, which had 6,144 cores, making it a 3x increase over the Navi 48 (RDNA 4) GPU.
AMD’s RDNA 5 GPUs are expected to bring improvements in areas such as ray tracing and AI. They may also help AMD reestablish its position in the high-end market against NVIDIA’s RTX series.
Here is a summary of potential RDNA 5 GPU configurations:
– **Flagship-Tier**: 96 CUs (12,288 cores), up to 512-384-bit memory bus, 24-32 GB VRAM
– **Mid-Tier**: 40 CUs (5,120 cores), 384-192-bit memory bus, 12-24 GB VRAM
– **Low-Tier**: 24 CUs (3,072 cores), 256-128-bit memory bus, 8-16 GB VRAM
– **Entry-Tier**: 12 CUs (1,536 cores), 128-64-bit memory bus, 8-16 GB VRAM
These configurations aim to provide a range of performance options for different market segments.
