What actually differs
Both GPUs launched in 2023: the Radeon RX 7800 XT on RDNA 3 and the Radeon RX 7900 GRE on RDNA 3.
Dense throughput for the Radeon RX 7800 XT against the Radeon RX 7900 GRE: FP32 37 vs 46 TFLOPS, FP16 75 vs 92 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 624 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 263 W for the Radeon RX 7800 XT and 260 W for the Radeon RX 7900 GRE. At FP32 that works out to 0.14 against 0.18 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.
