According to the results of our performance tests, Phenom II X6 1055T may become quite a worthy base for an overclocker system. However, before you draw the final conclusion, let’s take a look at its energy-efficiency and see if it proves to be as efficient as Intel processors. In order to get a more detailed picture we tested total power consumption of our Phenom II X6 1055T based system (without the monitor) in nominal and overclocked modes and compared it against the power consumption of similar platforms based on competing Intel CPUs from the same price range. The power consumption was taken “past” the power supply unit and this value represents the total power consumption of all system components. In this case we do not take into account the efficiency of the PSU itself.
During our tests we used 64-bit LinX 0.6.3 utility to load the systems to the utmost extent. Moreover, to ensure that we estimate the power consumption in idle mode correctly we activated all power-saving technologies, such as C1E, AMD Cool'nQuiet and Enhanced Intel SpeedStep.
I have to remind you that we overclocked our processors by raising their core voltages. Overclocking like that is known to increase the power consumption, as you can clearly see from the obtained results. The power consumption of our Phenom II X6 1055T processor doubles when the CPU is overclocked and loaded to the utmost extent. As a result, it is the most energy-hungry overclocker CPU of all our today’s testing participants, which is, in fact, quite logical because this processor has the largest number of cores. So, while the performance of the AMD six-core processor didn’t deserve any serious criticism from us, now we have to state that it can only be used in overclocker systems when power consumption doesn’t really matter.
