AMD's Radeon VII Packs A Lot More FP64 Performance Than Expected
Early on AMD said that the Radeon VII would provide 0.88 TFLOPS of FP64 performance, a sixteenth of the GPU's FP32 performance and around an eighth of what is offered on the Radeon Instinct MI50.
Since CES AMD has had a change of heart, deciding that their Radeon VII users deserved a little more FP64 performance from their new gaming flagship, making the graphics card more appealing to professional users while maintaining the performance advantages of their Radeon Instinct Lineup. Not the Radeon V offers 4x more FP64 performance (3.5 TFLOP) than what AMD originally planned, making the graphics card an FP64 monster given its £649.99 price point.
While FP64 is not useful for gaming applications, professional users will know that FP64 compute is a useful tool for a range of calculations, making the Radeon VII extremely appealing to some workstation users.
Our graphics cards are gaming focused, so you the addition of extra FP32 performance has no impact on our performance data, though workstation and pro users will certainly appreciate this hardware upgrade from team Radeon. AMD meant it when they said the Radeon VII is for both gamers and professional users alike.

That card can pump out over 7TFLOPs, while their gamer silicon like the RTX Titan can barely reach 0.5 TFLOPs.
Before Titan V, the HD7990 was still the top performing consumer card for double precision compute.Quote
Anyways, right now none of Nvidia's consumer-grade GPUs offers FP64 compute that is this high, aside from the Titan V, which is the only current-gen Nvidia consumer GPU that delivers half-rate Double Precision Compute.
Nvidia doesn't officially publish numbers for half precision compute for a lot of their graphics cards, so it is hard to make a proper comparison.Quote
The double precision side just comes down to core count, a fully enabled TU102(RTX) has 2 DP units per SM for 144 total, GV100(Volta) has 32 DP units per SM for 2688 total.Quote
