I thought AMD will leave RDNA for gaming and continue with CDNA for profesional use. I could be wrong though.

Nope, CDNA is exclusively for compute workloads and e.g. will be used in supercomputers. Radeon Pro's are for (professional) visualization, therefore you need regular GPUs.
And it's about time ... AMDs portfolio is completely outdated. Currently the most "up to date model" is the Radeon Pro VII, a chip from the end of 2018.

The W5700 exists as well -- AMD's pro cards are only one generation behind at this point, fairly common for a pro product since the testing & validation takes a lot more time than a consumer card.

Yes, but the card and GPU is even slower than the 2018-chip. For example in RadeonPro Renderer the VII is significantly faster and there's no debate about FP64 performance. The VII ist still the fastest chip ... and quiet old.

And the validation topic is the same for Nvidia, that's no excuse. AMD is simply not putting enougth efford into their Pro series, therefore they have to compete mainly via a cheaper price.
And current gen Ampere-chips will for example be still be faster in RadeonPro Renderer, because they have more horse power (this time the AMD-chip is simply the consumer-chip).

Actually the VII dates to about a year ago ...
https://www.tomshardware.com/news/AMD-announced-Radeon-Pr
... and offers up 6.5GFLOPS for $2.5K (newegg), while the A100 was introduced sometime in the fall of 2020 offering up 9.7GFLOPS of FP64 for about $10K (nextwarehouse).

So (2.5/6.5)/(10/9.7) = 38% (meaning one gets a GFLOP of FP64 compute on the AMD card for 38% of a similar amount of FP64 on the A100). So, if all you care about is FP64, like myself, then the AMD card is currently a no-brainer.

Oh and this W6800 will very likely have crippled FP64 (1/32 or 1/16 vs 1/2). So we wait for a so-called real FP64 update card from AMD sometime this fall which might be the first to break the 10GFLOPS FP64 barrier AFAIK.

Actually, as I mentioned and still w/o question: the chip is from the end of 2018, This is Vega20, specifically designed for the Instinct MI60 and MI50 models and later reused for the Radeon VII and then for Apple and at the end for the Radeon Pro VII.

And yes, it's cheap, simply because it has to be cheap because otherwise nobody would by it and instead use the market leader's hardware.

And FP64 performance is only a small part of the portion and for example in large scale deployments I have never heard from anyone using Radeon Pro's (maybe in some datacenters). For example there only exists a singular system in the Top500 list, witch uses a (unspecified) Vega20 card, the rest of the list uses nVidia (or is CPU-only).
Additionally your comparison is incomplete, because the (G)A100's FP64 is in the range of about 10 - 20 TFlops. The lower value belongs to the base shader (ALU) performance, the upper value is the preak performance via using the new FP64 Tensor Core v3 functionality with MMA ops, therefore in real world apps, the performace will be somewhere between these two values, depending on the concrete workload.
Additionally the A100 outperforms the Vega20 card in AI workloads by far.
Therefore over all even the latter CDNA hasen't managed to really outperform the A100.

And yes, the Navi21 is crippled according to FP64, because AMD has limited FP64 performance as nVidia does to save transistor space for other purposes (here 1/16 FP32), whereas nVidia even limits it to 1/64 FP32 performance (it is only available for compatibility purposes).

Also, there will be no real FP64 "update" from AMD. AMD has split up its development lines and compute workloads are covered by CDNA (later on this year CDNA2), whereas RDNA will be limited to graphics. And for example a CDNA-chip will never be used in a Radeon Pro because the chip isn't a complete/full-blown GPU any more because AMD has removed certain elements from the render pipeline in the architecture.
