FLOPS by Precision

What actually differs

The GeForce GTX 1660 is the newer part: Turing (2019) against the Titan RTX's Turing (2018).

The Titan RTX carries 18 GB more memory (24 GB against 6 GB), so larger models fit on one GPU before you shard. Bandwidth is 192 GB/s against 672 GB/s, which sets the ceiling on decode speed.

Power is 120 W against 280 W, and at FP32 the Titan RTX does more work per watt. Weight the FP8 and FP16 rows for LLM work and the FP64 row for HPC.
