Performance Tests
The performance of the X48 and X38 chipsets should really be close to identical, especially when using the same memory technology.  For our testing we’ll be comparing the new Gigabyte X48-DQ6 to the XFX nForce 780i SLI and ASUS P5E3 Deluxe motherboard that uses the X38 chipset.

First, let’s take a look at our more synthetic CPU and memory tests:

The Gigabyte X48-DQ6 is the fastest of the three motherboards shown here, though the gaps are relatively small in terms of real world results.  For a DDR2 memory configuration, the raw memory performance is actually much better than I expected as well.
