The Radeon Pro W7900 48GB is AMD's flagship RDNA 3 workstation GPU, offering 48 GB of ECC GDDR6 and full ROCm support through the Navi 31 workstation driver stack. At this VRAM capacity, it can run 70B models at FP16 and compete with the NVIDIA RTX 6000 Ada Generation in the workstation AI segment. It is one of the largest VRAM configurations available in an AMD consumer-accessible workstation card.

Architecture
RDNA 3 is AMD's chiplet-based GPU architecture, combining a 5nm Graphics Compute Die (GCD) with 6nm Memory Cache Dies (MCDs). It introduces AI accelerators and a new unified compute unit design.
AI Relevance
ROCm support for RDNA 3 is maturing but lags behind NVIDIA's CUDA ecosystem. AI accelerator units provide some inference acceleration, but lack the dedicated Tensor Core equivalent found in NVIDIA GPUs.
