Firstly: GPU-Z doesn't get the number of shaders by looking at the core itself, it just looks up data added by the developer (whom I assume isn't a staff member at ATi), their guess is as good as ours.
That and, yeah, the shot is clearly a joke, 52GHz memory? Yeah, I wouldn't hold your breath for that.
Yep, this is what w1zzard said in the last hour.
