Several custom RX5700 cards from several manufacturers are said to be going on sale during August. Release begins next week.
Primarily, they have custom cooling for overclocking and interesting visual appearances. Some are said to have custom circuit boards.
As previously noted, my "stock" RX5700XT 50th Anniversary "reference card" actually runs up to 2040MHz during benchmarks with no added overclock. Its factory overclocked relative to the standard RX5700XT -- the overclock is not large. Its quiet in normal gaming use. I understand AMD purposely made it that way. During benchmarking, when running over 1950MHz, I can barely hear it over case fans -- just the sound of air moving to my ears -- not fan-whine. But, my hearing is substandard. Just reference info FWIW.
The linked site has some articles with pictures and preliminary descriptions. Test reports should be coming later this month.
