Clock speeds will vary given this is a custom edition and not an aftermarket one. It should only be one version, given its performance tier is unlikely to have a 3GB or 9GB variant. Should have decent performance, but the price will be everything, since as we saw with the 5500XT, AMD is not afraid to price cards out of their class.

There is a mistype in the 5600 XT heading, it should read 6G as evidenced by the other shots.
