They did a mild segmentation with that one, by reducing the throughput from 1:2 to 1:4 in the consumer variant, with the hope of forcing people to buy the "professional" version.

Even with the throughput reduction, Radeon VII had a performance somewhat better than the previous best FP64 product, AMD Hawaii, due to the large and fast memory. Most later consumer GPUs from NVIDIA and AMD have never approached again such a high memory interface throughput.

Radeon VII has remained for many years the champion of FP64 performance per dollar. I am still using one bought in 2019, 7 years ago.

Last year was the first time when a GPU with good FP64 performance per dollar has appeared again after Radeon VII: Intel Battlemage B580. Unfortunately it is a small GPU, but nonetheless the performance per dollar is excellent.
