AMD's Radeon VII Packs A Lot More FP64 Performance Than Expected

When AMD first announced their Radeon VII graphics card, they stated that the graphics card would feature throttled FP64 performance, a downgrade that would prevent their gaming-oriented graphics card from cannibalising the sales of their enterprise-grade Radeon Instinct M50 and M60 offerings.  

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.

Your source is KO, any comparison to Nvidia for the FP64 compute ?Quote

NVidia only really has one (sort of almost) consumer card (Titan V) that comes anywhere near comparing since Kepler when they started building their gaming cards on distinct silicon.
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

Hmm, for whatever reason the website didn't like how the link was originally formatted. Strange.

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

While this won't give exact real world figures we can take the allocation of compute units on the architectures to get a maximum theoretical figure, with Pascal (Excluding GP100) at 1/32 double precision vs single precision (Or 1/64 half precision). Turing also has 1/32 max theoretical FP64 but of course moves to x2 FP16 like GP100 & Vega.
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
