Looks like I am a little to the party. I have been pestering you for the last week and your results have been on here for the past two days I really appreciate the time you spent on theses benchmarks and even measuring the power usage at the wall when running them. That is a great idea, and something I will more than likely incorporate in to my future tests.
I am not too surprised by the outcome giving the Lightning is clocked so high. I am surprised by the amount of power the lightning consumes when @ 1400Mhz+. I am seeing a whole lot more power being consumed and not much of a performance benefit. Like Balla mentioned, I think this has something to do with the low clocking Elpida memory holding the card back at that core clock. In my own tests I didn't notice much of an increase when cranking her up to close to 1400Mhz as well. I do see your Bioshock frame rates are higher than mine in the same test, assuming the settings are the exact same. This is more than likely because you are on high clocking Haswell setup? Crysis 3 finally broke my 1333Mhz stable overclock @ 1.2v. It's now fully stable @ 1320/1650 @ 1.2v. I will say even @ 1440P, this card is fast. I even recorded some videos using shadowplay showing the performance @ 1440P
Metro LL
Crysis 3
Modded Skyrim
I don't think I am going to shoot for 1400Mhz+ on this card when the NZXT G10 gets here. I may just go for silent gaming setup with a decently clocked card @ 1320/1650 or put it on another card?
Awesome job Elfear and thanks for doing this :thumbsup:
