Overclocking the FX-8150 from its base 3.6GHz clock to 4.4GHz boosted Dirt 3's performance at 1680x1050 by 4%. The 1920x1200 performance didn't budge a single frame.
The 4.4GHz overclock delivered just under 3% more performance in the Pass 1 test and 12% more in Pass 2. This allowed the FX-8150 to overtake the Phenom II X6 1100T, but it was still much slower than the i5-2500K and i7-2600K.
CINEBENCH R11.5 OpenGL saw no performance gain when overclocking the FX-8150, though the CPU score increased 17%.
