What actually differs
Both GPUs launched in 2020: the Radeon RX 6800 XT on RDNA 2 and the Radeon RX 6800 on RDNA 2.
Dense throughput for the Radeon RX 6800 XT against the Radeon RX 6800: FP32 21 vs 16 TFLOPS, FP16 41 vs 32 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.
Memory is 16 GB against 16 GB, fed at 512 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 300 W for the Radeon RX 6800 XT and 250 W for the Radeon RX 6800. At FP32 that works out to 0.07 against 0.06 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.
