i had stock as well, 6ghz. and also your feature test 1 is really low, did another feature 1 and 2 test with 6.6 ghz and i get 169.64 at feature test 1 and 17.23 at feature test 2. Thats with 1163mhz / 6.6 ghz. edit: At 1228mhz with 6.6ghz i get 175.43 and 17.90 , and with 1241mhz i get 18.something, i doubt its because of unstable overclock now because my card 101% isnt stable at 1241mhz only at this tests because they're too short for it to fail. Something must be hogging your resources or you have another version. What version are you using? i have 1.1.2.

well idk, I had a bunch of stuff open there could be something eating few cycles.. I saw Steam can, also firefox and I had both open 🤓 ok found one older screen at 1215mhz, guess yeah its those extra things in background conflicting.. 🙂 http://abload.de/thumb/vantamemaxoc4.7disln.png And I see you're using windows7 this can be faster by some 3dmarks, I know 3dmark2011 cpu physics test scores almost 1000points more at same cpu freq. vs win8., while 3dmark2013 physics the opposite and runs faster in win8, esp. win8.1.

Yea, who knows,doesnt matter if your games run properly, but i was just curious. Even so, we'd need to overclock the 780 a lot to reach that 285 in color fill, i know that almost equals 0 in games but still,its interesting. Whats more interesting about tonga is its tesselation performance. Can't wait to see the highend models.

Actually 285 only scores so high cause of some compression technique and this isnt always possible, look here "Remember how we spoke about the benefits of the Tonga architecture that may not be evident when looking at a spec sheet? Here's an example of where the spec sheet doesn't lie. Reduced memory bandwidth and lack of available compression optimisations open to the R9 285 means poorer performance than the outgoing R9 280." JustCause2 example http://hexus.net/tech/reviews/graphics/74033-sapphire-radeon-r9-285-dual-x-oc-28nm-tonga/?page=9

$50 more, worse OC-er and 50% less VRAM and bandwidth than ancient 7950(280) They have basically tied with 30-something month old GK104, on virtually every metrics. The most underwhelming gpu launch since I can remember.
