Please elaborate on drivers used. I also would like to see how Mantle works in crossfire setups.
Great Review @Steve!
I've been with AMD ever since. I love underdogs.
Crossfire doesn't work?! Unless I am blind every benchmark showed a single GPU with an iCore 5 as superior. Yawn
@Steve I got an odd question for ya, when you were testing im curious about the core clocks on the R7 250 and A10's R7. Now in CFX and SLI normally it goes with the lower clock speed and hits the GPU's down to those levels. Just curious if you noticed anything like that as im curious if playing with the clock speeds in the Bios like I did (I bumped my friends one up to 960mhz) would make a difference in CFX (At least a noticeable one).You might be blind then. The Crossfire setup was faster in three of the six games tested as stated in the conclusion.
In your article you implied that you should chose the faster GDDR 5 memory over the slower DDR 3 memory. Did you do any performance comparisons between r7 250 DDR 3 and the GDDR 5 memory when in crossfire with the Kaveri?
Thanks

Ah ok, was curious if the 7850k would actually while still improving performance in CFX was holding back the power by forcing downclocking. Good to note, thanks for the response.No that wasn't happening, both GPU's were running at full speed when Crossfire was working. I didn't try and match the clock speeds through overclocking though.
