What actually differs
The Radeon VII is the newer part: Vega, launched in 2019, against the Radeon RX Vega 64's Vega from 2017. 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 VII against the Radeon RX Vega 64: FP32 14 vs 13 TFLOPS, FP16 28 vs 25 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.
Memory is 16 GB against 8 GB, fed at 1.0 TB/s versus 484 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 VII and 295 W for the Radeon RX Vega 64. At FP32 that works out to 0.05 against 0.04 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.
