AMD Radeon PRO W7900 48GB

The Radeon PRO W7900 is the top of AMD's RDNA 3 workstation line and, at 48 GB of ECC GDDR6 on a 384-bit bus at 864 GB/s, it was for two years the largest frame buffer you could buy from AMD outside the Instinct line. Its 96 compute units and 192 AI accelerators deliver 61.3 TFLOPS of FP32 vector and 123 TFLOPS of FP16 matrix, with 96 MB of Infinity Cache behind them, in a 295 W triple-slot card. RDNA 3 has no FP8 path and no structured sparsity, so 123 TFLOPS is the honest ceiling; the newer 32 GB Radeon AI PRO R9700 beats it by more than three times on matrix throughput while giving up a third of the capacity. AMD publishes no FP64 or BF16 rate for this card.
