Ya it does that. For whatever reason it can't tell the 56 and 64 apart. Same with the 580/570 and 480/470. That's one of the reasons GPUz is required.
One of these days I'll update the scoreboard... travel hasn't been helping.
It's a good question. Generally when I hear "optimizations" I think they mean they cut out unnecessary features. I'd bet that the RDNA architecture has a lot less of the compute/workstation features that makes Vega so versatile. Though with RDNA you get the strong IPC uplifts I guess. AMD did say at one of their last shows that they would still be using the Vega architecture in workstation cards going forward, and that RDNA would be focused on the gaming market. I take that as the support for Vega won't stop for a while.
Hopefully they will enable some of the Vega features that we haven't seen yet (like rapid packed math) whenever the RDNA cards start to show up since they support them as well.
I'm curious how well the 5700 chips will OC too. Tweaking on the VII is fun already and it looks like the regular 5700 will be a strong overclocker. Could be fun just on it's own.
To be fair, I cleaned and restored both so they weren't that nice looking when I originally got them. Generally speaking, unless things are physically broken, these clean up really well.
This is how dirty the barrel plate was originally...
