AMD Phenom II X6 1090T And 890FX Platform Review: Hello, Leo

Power Consumption

At idle, the Phenom II X6 1090T results in slightly higher system power than the Phenom II X4 965. Under the load of Prime95, we also see somewhat higher energy usage numbers.

Compare those figures to Intel’s, though. Under load, the Phenom IIs generate comparable system power draw. But at idle, AMD’s Phenom II CPUs use quite a bit less.

Of course, these are snapshots at the top and bottom of each processor’s range. The more realistic measure of consumption comes from our exploration into Turbo CORE on page three, where we determined that, despite its additional complexity and Turbo CORE technology, the Phenom II X6 1090T only averages a few watts higher power use in a logged PCMark Vantage run.
