FLOPS by Precision

What actually differs

Both launched in 2023, the L40 on Ada Lovelace and the RTX 4500 Ada on Ada Lovelace.

The L40 carries 24 GB more memory (48 GB against 24 GB), so larger models fit on one GPU before you shard. Bandwidth is 864 GB/s against 432 GB/s, which sets the ceiling on decode speed.

Power is 300 W against 210 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.
