NVIDIA GeForce GTX 1660 Super 6GB

The GeForce GTX 1660 SUPER is the plain GTX 1660 with its memory replaced. The silicon is untouched, 1,408 CUDA cores at a 1,785 MHz boost for 5.03 TFLOPS FP32 and 10.05 TFLOPS FP16 on a TU116 die with no Tensor Cores and no RT Cores, but the 6 GB of GDDR5 becomes 6 GB of GDDR6 at 14 Gbps, taking bandwidth from 192 to 336 GB/s for five more watts. That is a strange-looking product and a sensible one: on this class of card almost nothing is arithmetic-bound, so buying bandwidth rather than shaders was the cheaper way to make it faster. For compute it means the SUPER and the plain 1660 will show identical peak throughput and behave quite differently on anything that streams weights, which is most inference. Its half-precision path runs at twice single precision, unlike every Pascal card, which is the one genuinely modern thing about it.
