    In most tests/reviews I've read, there's almost no difference between using DDR3 2400 and DDR3 1600 for gaming. Does this APU benefit more than a regular CPU + discrete GPU combo from having a higher memory MHz? At first glance, it seems a bit overkill using DDR3 2400 on what I'd consider a budget-friendly system, but I have no hands-on experience with APUs yet. Thanks for the info on dual graphics compatibility, btw.

    Did you look at the A10-6800K results in this review, we tested it with both 1600MHz and 2400MHz memory.

    I actually only checked the game-graphs on my first read and you didn't test 1600MHz memory with games, but now I checked some of the other graphs and it seems the 1600MHz memory beats 2133MHz in some of them. I'm still curious to see the impact on games. :)

    The A10-6800K was indeed tested with 1600MHz and 2400MHz memory in the gaming benchmarks.

    Ah, I see now, you were talking about the 6800K. My confusion is that I was just looking for the Kaveri results and ignoring the previous generation chips.

    It does make a difference to have that higher speed ram when equipped with an APU. One of my friends bought an A10 6800k with an gigabyte A88X Micro Board and for the first month till he got another paycheck had 8gb of DDR3 1333 in it (He had this memory sitting around from an old machine) and used it to play League with me and a few friends which it gave a decent amount of performance though he could only run it on high with shadows on low to keep around 60FPS. He recently grabbed some DDR3 2133 (8gb) and started league up and now he can play it on ultra 1080p with 60fps with shadows on medium (A few drops in big team fights into the 50s). There is some improvement to be had with higher ram when using the iGPU on an APU, it does make a difference at times (Albeit depends on what ram your comparing it to) especially once you start going from something like 1600x900p to 1920x1080p.

    Without that dedicated 1gb of GDDR5 ram like on the HD 7750 (Which the 7850k is most closely resembled with in terms of performance) you would get a loss in performance. So the faster the memory it has access to, the closer the performance will be to that 7750 (If you compared clock to clock results). The DDR3 2400mhz is not the GDDR5 ram that the GPU would get, but its closer than DDR3 1600 which does make a noted difference in gaming tests. Its not like "ZOMG NIGHT AND DAY BABY" but if you want the best performance from it thats how your going to do it.

    That's good info, thanks! :)
