- my123 6y agoIt isn't at the software level, FP16 goes through the tensor cores on Turing onwards: https://www.anandtech.com/show/13973/nvidia-gtx-1660-ti-review-feat-evga-xc-gaming/2 https://www.anandtech.com/show/13973/nvidia-gtx-1660-ti-revi...)
- dogma1138 6y agoThe ALUs are capable of half precision regardless of the tensor cores and aren’t restricted. For “tensor ops” in GeForce cards FP16 with FP32 accumulate is done at half rate so you don’t get double the performance which you do get in Quadro and Titan cards using the same die.
