We have spent quite a bit of time with AMD's latest processor, the A-series of APUs previously known as Llano, but something we didn't cover in the initial review was how overclocking the A8-3850 APU affected gaming performance for the budget-minded gamer. Wonder no more!
In this short video we took the A8-3850 and pushed the base clock frequency from 100 MHz to 133 MHz and overclocked the CPU clock rate from 2.9 GHz to 3.6 GHz while also pushing the GPU frequency from 600 MHz up to 798 MHz. All of the clock rates (including CPU, GPU, memory and north bridge) are based on that base frequency so overclocking on the AMD A-series can be pretty simple provided the motherboard vendors provide the multiplier options to go with it. We tested a system based on a Gigabyte and an ASRock motherboard both with very good results to say the least.
We tested 3DMark11, Bad Company 2, Lost Planet 2, Left 4 Dead 2 and Dirt 3 to give us a quick overall view of performance increases. We ran the games at 1680x1050 resolutions and "Medium"-ish quality settings to find a base frame rate on the APU of about 30 FPS. Then we applied our overclocked settings to see what gains we got. Honestly, I was surprised by the results.
While overclocking a Llano-based gaming rig won't make it compete against $200 graphics cards, getting a nice 30% boost in performance for a budget minded gamer is basically a no-brainer if you are any kind of self respecting PC enthusiast.
