Still weird to me that they continue to give each GPU both low-precision and high-precision silicon. Why not just make two parts, one high-precision and one low

- deepnotderp 8y agoMost ALUs can re-use the components to be relatively easily reconfigured between low and high precision, the overhead cost tends to be single digit percent, which is generally considered worth it for the added flexibility.
- p1esk 8y agoI remember hearing that V100 FP32 cores could be used as pairs of FP16 cores for specific use cases, however I don't think the FP64 cores are decomposable in the same way.
