Intel Core 2 Evolves- QX9650 45nm Penryn - Power Consumption Tests

We've got our first 45nm Intel processor in hand, this in the form of the Yorkfield quad core QX9650.

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.

 

 

This was the most impressive test. Using the new 45nm process has reduced the amount of power the system uses under load and especially idle with its sleep state. The new 45nm CPU is the most efficient desktop CPU from Intel yet.
