You pay the price in locked down fp64 functionality. (Typically quarter or less of fp32 rather than expected half.)

- dragontamer 7y agoMost people don't need double-precision. Similarly, Threadripper loses on RDIMMs, LRDIMMs, and have 1/2 the memory channels and 1/2 the PCIe lanes. Most people don't need that either. Of course consumer products have fewer features than enterprise products. The chip manufacturers need to leave some features for "enterprise". The general idea is to extract more wealth from the people who can afford it, while providing consumers the features they care about at a lower cost. ----- Really, the feature enterprise GPUs need seems to be SR-IOV, or other PCIe-splitting technologies. This allows a singular GPU to be split over many VMs. Double-precision floats is niche to the scientific fields, also "enterprise" but I don't think most enterprise customers use double-precision floats.
