Something is seriously off here—either with this specific sample, the drivers, or something else entirely (maybe just the architecture itself)
PC Gamer measured power draw directly at the card using specialized gear, and it turns out the thing is pulling 150W the whole time.
As far as I know, the reference card only has a single 6-pin connector, so we're looking at some aggressive power throttling here. (The GTX 970 in the test doesn't have this issue, presumably because it has at least an 8-pin, whereas this thing draws power similar to an AMD RX 480)
Also, trying to overclock a card that’s already power-throttling at stock boost frequencies is insane. No wonder the OC results are pathetic. Honestly, it's a miracle they even hit nearly 200W with just one 6-pin connector; that flies in the face of all standard specs.
Bottom line: something is wrong with this card. Either the scaling is abysmal, or Polaris has efficiency levels similar to Maxwell, which I find hard (read: refuse) to believe.
After all the massive hype surrounding Polaris's performance-per-watt and the speculation that the card would only pull 90W, it turns out the reference model starts power-throttling right out of the gate.
