With power use remember too that a proportion of the wu runtime is not with GPU under any load so again that is less cost.


I've yet to see any power use figures for 6000's but looking at jspace's results the 6970 should fall near the 7770 for performance


I was making an estimation based off of this: http://www.anandtech.com/bench/Product/536?vs=518

At the bottom it shows load temps with OCCT on both GPUs. A 2700k @ 4.7GHz and GTX 570 load is right at 400W - sometimes just under or over. The 7770 looks to be right around 200W. I'm guessing HCC GPU isn't as stressful as OCCT, but the power consumption numbers still should be relative to the HCC GPU tasks. I have an APC UPS that tells me current power draw. Of course, that is from the wall and I'm not certain of the PSU Efficiency @ 400W with a Corsair TX750.

I have no idea what the manufacturer's power rating are.

I just finished a HCC GPU WU on my A-3650 APU with Radeon 6530D (320SPs) @ a total of 13:27. It takes quite awhile and the UPS on that PC says 90W with a HCC GPU task and 3 HCMD 2 tasks running.

It is a bummer. The iGPU on my A6 3650 works but not on this 2700k.
