AMD Radeon PRO W7600 8GB vs AMD Radeon RX 7900 XT 20GB

The Radeon PRO W7600 is the newer part: RDNA 3, launched in 2023, against the Radeon RX 7900 XT's RDNA 3 from 2022. 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 PRO W7600 against the Radeon RX 7900 XT: FP32 20 vs 52 TFLOPS, FP16 40 vs 103 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.

Memory is 8 GB against 20 GB, fed at 288 GB/s versus 800 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 130 W for the Radeon PRO W7600 and 315 W for the Radeon RX 7900 XT. At FP32 that works out to 0.15 against 0.16 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.
