NVIDIA GeForce GTX 1660 Ti 6GB vs NVIDIA Quadro RTX 6000 24GB

The GeForce GTX 1660 Ti is the newer part: Turing, launched in 2019, against the Quadro RTX 6000's Turing from 2018. Newer architectures typically add lower-precision formats and better throughput per watt, so check the precision rows your workload actually uses.

Dense throughput for the GeForce GTX 1660 Ti against the Quadro RTX 6000: FP64 0.2 vs 0.5 TFLOPS, FP32 5.4 vs 16 TFLOPS, FP16 11 vs 131 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.

Memory is 6 GB against 24 GB, fed at 288 GB/s versus 672 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 120 W for the GeForce GTX 1660 Ti and 295 W for the Quadro RTX 6000. 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.
