AMD Radeon RX 7600 XT 16GB vs AMD Radeon RX 7900 GRE 16GB

The Radeon RX 7600 XT is the newer part: RDNA 3, launched in 2024, against the Radeon RX 7900 GRE's RDNA 3 from 2023. 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 7600 XT against the Radeon RX 7900 GRE: FP32 23 vs 46 TFLOPS, FP16 45 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 288 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 190 W for the Radeon RX 7600 XT and 260 W for the Radeon RX 7900 GRE. At FP32 that works out to 0.12 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.
