Video Perspective: Gaming on an Overclocked AMD A10-7850K APU

Overclocking the memory and GPU clock speeds on an AMD APU can greatly improve gaming performance - it is known. With the new AMD A10-7850K in hand I decided to do a quick test and see how much we could improve average frame rates for mainstream gamers with only some minor tweaking of the motherboard BIOS.
Using some high-end G.Skill RipJaws DDR3-2400 memory, we were able to push memory speeds on the Kaveri APU up to 2400 MHz, a 50% increase over the stock 1600 MHz rate. We also increased the clock speed on the GPU portion of the A10-7850K from 720 MHz to 1028 MHz, a 42% boost. Interestingly, as you'll see in the video below, the memory speed had a MUCH more dramatic impact on our average frame rates in-game.
In the three games we tested for this video, GRID 2, Bioshock Infinite and Battlefield 4, total performance gain ranged from 26% to 38%. Clearly that can make the AMD Kaveri APU an even more potent gaming platform if you are willing to shell out for the high speed memory.
