What actually differs
Both GPUs launched in 2017: the V100 SXM2 16GB on Volta and the V100 PCIe 16GB on Volta.
Dense throughput for the V100 SXM2 16GB against the V100 PCIe 16GB: FP64 7.8 vs 7 TFLOPS, FP32 16 vs 14 TFLOPS, FP16 125 vs 112 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 900 GB/s versus 900 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 V100 SXM2 16GB and 250 W for the V100 PCIe 16GB. At FP32 that works out to 0.05 against 0.06 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.
