My batch 2 freq rated at freq 575 is outstanding.
It can do as high as freq 631 does 5120 gh at .26 watts per gh.
On the other end if you run it with a titanium evga t2 at freq 575 you get 0 hardware errors and .246 watts per gh.

Wonder what the suposid gain was for making them at 700 out of the box. What are new ones looking at power wise if not .25. I know originally people were running them with evga 1300 watts. Now that won't handle it if I understand correctly.
The gain was to use less chips to attain the same hash or so. So for the Chinese's "Full Volt Full speed" portfolio, cost effective BUILD, they did well, since they take 135 chips now to reach 4.73TH/s instead of 162 or whatever.
So their costs went down and we could argue that the price we pay went down too. But the end result is .29~ efficiency instead of .25, since the chips need to run at a higher voltage. (And very well maybe a higher failure rate, but i can only speculate.)
And the EVGA 1300 watts can do it, albeit at reduced efficiency. I estimate about up to 1480w at the wall.
My EVGA 1600 P2 does 1415 watts which equate to 1295w DC, but i do not have the fan running at full speed.
My B8 stay's at 4.7 almost always. It seems they have done a good job with latest design of getting a product that is pretty consistent on speed. It is cranked up on freq, so OC is pretty much out of question (at least on how far I would push it).
The ones with 5T and or ones with more chips, I don't think we will see again. They are able to use less chips now and this lowers costs, makes profits higher. And hopefully that means they can sell for lower. But I think 4.7T version is here to stay.
