Just to add in something I wasn't sure at that point, Vega 10 FP64 can only can reach 1/16th of FP32 while Vega 20 can do 1/2, so the chip must have changed quite a bit under the hood. Double Precision is also something that cost quite a lot of energy, hence why it got cut down in modern GPUs both by AMD and NVidia. NVidia nowadays mostly uses 1/32th, and all RTX cards, including the Quadro, do so. The original Titan had 1/4, while the Volta-based Titan V has 1/2 like the Vega 20, making the latter the probable target if the FP64 capability of the Radeon VII hasn't been cut down. |
