FLOPS by Precision

What actually differs

The GeForce RTX 4080 Super is the newer part: Ada Lovelace (2024) against the L40's Ada Lovelace (2023).

The L40 carries 32 GB more memory (48 GB against 16 GB), so larger models fit on one GPU before you shard. Bandwidth is 736 GB/s against 864 GB/s, which sets the ceiling on decode speed.

Power is 320 W against 300 W, and at FP32 the L40 does more work per watt. Weight the FP8 and FP16 rows for LLM work and the FP64 row for HPC.
