Overclocking

Being an AMD CPU with unlocked multiplier the overclocking is very similar to the earlier Phenom II processors we’ve reviewed. Just launch the AMD Overdrive and crank up the multiplier and voltage until you hit stability issues or the core temperature gets too high for your liking.

To keep the temperature in check we used the Antec Kühler 920 water cooler, which also happens to be almost identical with the FX water cooler that AMD ships with some of the FX-chips. With the help of the Kühler we managed to push the sample chip up to 4,7 GHz (23,5 x 200) using 1,4125 V (measured) core voltage. 1,1 GHz over the reference clock speed on all eight cores is pretty impressive.

Performance

• CPU: AMD FX-8150
• CPU-cooler: Antec Kühler H20 920 (+ fan for the voltage regulation)
• Motherboard: Asus Crosshair V
• Memory: G.Skill Ripjaws 2*2 GB DDR3 2000 CL9
• Graphic card: HIS HD5870 iCooler Turbo
• Power supply: Silverstone DA700

To see how the new architecture performs we put the FX-8150 through the usual CPU-test suite, which includes a variety of benchmarks that test both single- and multi threaded performance. All the tests were ran three times; first with the CPU at stock speed and with the turbo-mode enabled or disabled and of course also at the overclocked 4,7 GHz speed.

3DMark Vantage

In 3Dmark Vantage the FX-8150 isn't off to a great start, as it falls between the 6-core 1090 and 1100 Phenoms. Enabling the Turbo-feature does make it the fastest AMD chip we've ever seen, but the margin to the X6 1100 isn't huge. Overclocking gives the FX a really nice boost, but it still can't compete with the overclocked i7 870.
