AMD's Capsaicin event at GDC was quite the blast, if not for the reveal of their Radeon Pro Duo dual-GPU, VR-focused monster card, they also took time to show off just how potent Polaris 10 actually was. And someone was lucky enough to get a close-up of its behind. And it looks like any other GPU's derrière.
Looking closely, which is easy here, you can see that the connectors include three DisplayPort (presumably 1.3) one HDMI (likely 2.0) and a DVI-D port. And we get our first peek at the prototype PCB as well. Though it's only a prototype, and this could change. There it is. It is an engineering sample, so things could change in the future. The best part is the small form-factor it happens to be in. AMD is definitely committed to bringing more power to smaller form factors.
This is "Big Polaris", or Polaris 10, that's running the newest Hitman using DX12. It's stuffed in a Cooler Master Elite 110 case, meaning the board is minuscule to be able to fit into that case. The PCB is probably around the size of the R9 Nano and should consume less power than any Fiji based board to date.
