NVIDIA GeForce GTX 1660 Ti 6GB

The GeForce GTX 1660 Ti is Turing with the Turing removed: the same 12 nm generation and the same SM design as the RTX 20 series, but on a TU116 die that ships with no Tensor Cores and no RT Cores at all. What survives is the part that matters for cheap compute, a full-rate half-precision shader path, so its 1,536 CUDA cores at a 1,770 MHz boost give 5.44 TFLOPS FP32 and 10.87 TFLOPS FP16, twice the single-precision rate rather than the fraction every Pascal card manages. Against an RTX 2060 of the same era that is a real loss, since the 2060's Tensor Cores take FP16 to four times the shader rate and add an INT8 path entirely, but against a GTX 1070 it is the first NVIDIA consumer card below the RTX line where running a model in half precision is actually faster. It pairs that with 6 GB of GDDR6 at 12 Gbps for 288 GB/s inside 120 W, which is the frame buffer that decides most of what it can do.
