FLOPS by Precision

What actually differs

The V100 SXM2 32GB is the newer part: Volta (2018) against the V100 PCIe 16GB's Volta (2017).

The V100 SXM2 32GB carries 16 GB more memory (32 GB against 16 GB), so larger models fit on one GPU before you shard. Bandwidth is 900 GB/s against 900 GB/s, which sets the ceiling on decode speed.

Power is 250 W against 300 W, and at FP32 the V100 PCIe 16GB does more work per watt. Weight the FP8 and FP16 rows for LLM work and the FP64 row for HPC.
