What actually differs
The Radeon RX 6950 XT is the newer part: RDNA 2, launched in 2022, against the Radeon RX 6800 XT's RDNA 2 from 2020. Newer architectures typically add lower-precision formats and better throughput per watt, so check the precision rows your workload actually uses.
Dense throughput for the Radeon RX 6800 XT against the Radeon RX 6950 XT: FP32 21 vs 24 TFLOPS, FP16 41 vs 47 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 576 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 335 W for the Radeon RX 6950 XT. At FP32 that works out to 0.07 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.
