Intel Core i7 CPU Scaling with HD 6850 in Crossfire - Test System Setup and 3DMark Vantage

You're not running 4.2GHz on a $1,000 CPU? That's cool - Let's see how this $400 VGA setup runs at different clock speeds.

We would like to thank the following companies for supplying and supporting us with our test system hardware and equipment: Intel, ASRock, Kingston, Mittoni, Noctua and Corsair.

 

What we've done today is clock our 980X to different speeds while disabling cores at times to simulate low priced and lower clocked CPUs. For example, we leave the BCLK at 133MHz, disable two cores and drop the multiplier down to 23 to give us a clock speed of 3.06GHz. This will help us simulate the performance of an i7 950.

 

While it's not perfect, as we've got a bit more L3 Cache on our 980X, the speed is going to be one of the most important factors in helping us judge the scaling benefits of higher end CPUs.

 

Apart from the highest clock speed, the BCLK has been left at 133 and only the Multiplier has been adjusted from 23 - 29.

 

Due to the amount of testing that had to be done, we've cut our benchmarks down slightly, but we've included all the important stuff including all the resolutions that we normally test at.

 

Let's get started!

3DMark Vantage is the new industry standard PC gaming performance benchmark from Futuremark, newly designed for Windows Vista and DirectX10. It includes two new graphics tests, two new CPU tests, several new feature tests, and support for the latest hardware.

 

3DMark Vantage is based on a completely new rendering engine, developed specifically to take full advantage of DirectX10, the new graphics API from Microsoft.

As we move the clocks up we see a little positive movement, but nothing major. The biggest gains are seen at 4.2GHz with all our cores enabled.
