What actually differs
Both GPUs launched in 2023: the Radeon PRO W7700 on RDNA 3 and the Radeon PRO W7900 on RDNA 3.
Dense throughput for the Radeon PRO W7700 against the Radeon PRO W7900: FP32 28 vs 61 TFLOPS, FP16 57 vs 123 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.
Memory is 16 GB against 48 GB, fed at 576 GB/s versus 864 GB/s. More memory per GPU means larger models fit before you have to shard across cards, which often matters more than raw TFLOPS for inference.
Power budgets are 190 W for the Radeon PRO W7700 and 295 W for the Radeon PRO W7900. At FP32 that works out to 0.15 against 0.21 TFLOPS per watt.
For LLM training and inference, weight the FP8 and FP16 rows and memory capacity most heavily. For scientific and HPC workloads, the FP64 row is the one to read.
