More than one article with this sort of headline:

AMD Radeon VII Won’t Offer Full-Speed Double Precision [Compute function]
These sorts of headline make it seem like a "fault". Thing is, double precision compute is not used in games -- and Radeon VII is for games.
Games that use compute will use single precision Compute -- Radion VII is blazingly fast at single precision:

Radeon VII — ... 13.8TFLOPs [single precision]..
the recent focus on AI and ML, .. tend to prioritize lower types of mathematical precision [i.e. single precision compute]
Radeon VII "gaming relevant" FP32 (float) performance is 13.8TFLOPs.
Nvidia RTX 2080 Ti is 13.5TFLOPs.
Nvidia RTX 2080 (what Radeon VII competes with pricewise) is only 10.0TFLOPs.
Then, the article above continues:
Quote
the Radeon VII will offer 862GFLOPS [of FP64 double precision]
RTX 2080 Ti only offers 420GFLOPs and RTX 2080 only offers 315GFLOPs. But the article doesn't mention that.
Compute is not yet a big deal in games. However, AMD has traditionally lead in "compute" (why it was favored for cryptocurrency mining) and it continues to lead gaming GPUs in that function.
