AMD Radeon PRO W7900

Product Overview​

AMD Radeon PRO W7900 is AMD's flagship professional workstation graphics card based on the RDNA 3 architecture, released in 2023, and the first GPU to support DisplayPort 2.1. With 48GB GDDR6 ECC memory, 864 GB/s bandwidth, and 61.3 TFLOPS FP32, it is AMD's main product for competing against the NVIDIA RTX series in AI workstations and local large-model inference (vendors such as Gigabyte offer an AI TOP 48G variant targeting LLM fine-tuning).

Strategic position: thanks to its large 48GB memory and ECC error correction, the W7900 is a low-cost option for running 70B-class models locally (four cards reach 192GB), competitive in domestic-substitution and budget-sensitive scenarios.
