In the first part of the FX-8150 review, we only pushed the FX 8150 CPU to new heights under the cooling authority of Corsairs Hydro 80. 4.8-4.9Ghz was doable during the entire test suite. Though for a daily overclock that all in one cooling solution will not be able to cut it at 4.9Ghz with my press CPU. Temperatures during Prime 95 8 thread test were rapidly breaking 92°C just after a few minutes. I hope for AMDs sake the retail silicon will be less of a hothead. And let's pray to the gods of hardware that they can bring both the heatouput and power consumption to more acceptable levels. But time for some daily OC settings in a quick comparative clash.
- 1090T overclocked at 4Ghz at 1.4Vcore, NB speed of 2600Mhz
- FX-8150 overclocked at 4.6Ghz at 1.42Vcore, NB speed 2400mhz
- 2600K overclocked at 4.5Ghz at 1.35Vcore
- i7 990X overclocked at 4.2Ghz at 1.35Vcore, 3200 uncore
Ram speeds were set at 1600mhz CL8-8-8-24 command rate 1T for all competitors. Only multiplier overclocking applied. We used the above speeds as they kept all of the CPUs in safe operating temperatures (sub 75°C) under Prime95 testing. Your mileage can vary ofcourse.
Once the CPUs are overclocked, the Cinebench scores scale accordingly. The gap between the the 6 core and FX "8" core CPU remains tiny. The 2600K@4.5Ghz enlarges the gap significantly. Chess action now. Deep Fritz 12 tells a similar tale then the Cinebench results. the FX CPU pulling away from the predecessor, even if not by a big amount.
Linear scaling with the added clockspeeds in POVRay. The gap between the AMD CPUs remains pretty constant, even at a 600Mhz CPU advantage for the FX CPU. The Gulftown CPU get's a decent boost over the stock setup, where the result was closer to the FX CPU.
Encoding a video into an HD version via the X264 encoder still shows strong pass 2 performance of the FX 8150. Intel being too strong in pass 1 of the 2.0 version.
Winrar is FX territory. Not even the 1100mhz higher clocks of the 2600K can bring it closer to AMDs latest offering. Weirdly enough the Gulftown hardly benefits from the extra speed.
Multithreaded Superpi at 2.42Gb test setting, shows the FX CPU gaining serious ground on the Intels. While at stock there was over half a minute gap, this has been reduced to half the time.
