AMD Radeon RX 6700 XT 12GB vs AMD Radeon PRO W6800 32GB

Both GPUs launched in 2021: the Radeon RX 6700 XT on RDNA 2 and the Radeon PRO W6800 on RDNA 2.

Dense throughput for the Radeon RX 6700 XT against the Radeon PRO W6800: FP32 13 vs 18 TFLOPS, FP16 26 vs 36 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.

Memory is 12 GB against 32 GB, fed at 384 GB/s versus 512 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 230 W for the Radeon RX 6700 XT and 250 W for the Radeon PRO W6800. At FP32 that works out to 0.06 against 0.07 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.
