AMD Phenom X4 B3 Stepping Analysed - Power Consumption Tests

AMD's Phenom has recently undergone modifications to make it more competitive. Can it now hold a candle to Intel?

Power Consumption

 

We are now able to find out what kind of power is being used by our test system and the associated graphics cards installed. Keep in mind; it tests the complete system (minus LCD monitor, which is plugged directly into an AC wall socket).

 

There are a few important notes to remember though; while our maximum power is taken in 3DMark06 at the same exact point, we have seen in particular tests the power being drawn as much as 10% more. We test at the exact same stage every time; therefore tests should be very consistent and accurate.

 

The other thing to remember is that our test system is bare minimum - only a 7,200RPM SATA-II single hard drive is used without CD-ROM or many cooling fans.

 

So while the system might draw 400 watts in our test system, placing it into your own PC with a number of other items, the draw is going to be higher.

 

 

The power usage of both setups are actually pretty close. However, AMD's SOI approach has been better than Intel's strained silicon. This however is done with the Intel 65nm CPU; we didn't have any 45nm CPUs on hand so we can expect to see Intel's power usage at 45nm drop below the AMD limit.
