SuomeksiPOWER CONSUMPTION & TEMPERATURES
When not loaded, all of the CPUs down-clocked themselves to mere 800 MHz, which explains the very similar idle power consumptions and temperatures. When looking at the idle power, please keep in mind that the setup also featured the Ati HD4870 graphic card, which alone make for over 70 W of the idle consumption. With all the CPUs being very similar, it's no surprise that the loaded results became a game of which has the most cores and highest clock speed. The 965 BE C3 really tops the charts, and when clocked to 4 GHz the power consumption really shoots through the roof. At stock speeds the rest of the bunch remain under the 300 W mark.
For the temperature results the same Zalman CNPS-10X Extreme cooler with the Zalman thermal paste were used, the fan was manually set to run at full speed throughout the testing. Also in this test the 965 BE really stands out from the crowd, but the rest scored very close to each other with idle temperatures being around 20°C and loaded ranging from 35 to 40°C.
ConclusionAt the time being, AMD can't really compete with the overwhelming performance of the Intel i7-platform, but in the very popular, and so in sense also way more important mid- and lower range markets the competition is very close. AMD really has offerings in all price gaps and one can also build a very affordable quad-core setup using the offerings in the Athlon product range. This time we had a nice cross-section of the Athlons, as well as a single Black Edition Phenom processor. This combined with the earlier results from the current flagship Phenom 2 X4 965 BE gave some really nice look at what kind of performance one can expect in different price stops. Starting off with the overclocking results. For enthusiast overclockers the Phenom is the way to go, but the Athlons proved to be pretty decent as well - 400 Mhz add across the board is a nice gain over the stock speeds. The clocking didn't run the power consumption and temperatures berzerk either, so I can suggest every buyer out there to at least try pushing the FSB for some extra performance. It's hard to tell any particular winner from this roundup as it's really just a sample showing what you can get at different prices. Depending on how much multi-threaded apps you're going to use, even the cheapest Athlon II X2 255 may cut it. |
