What actually differs
Dense throughput for the R200 against the R200-8F: FP32 32 vs 32 TFLOPS, FP16 128 vs 128 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.
Memory is 16 GB against 32 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 150 W for the R200 and 160 W for the R200-8F. At FP32 that works out to 0.21 against 0.20 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.
