Motherboard Testing

Testing a motherboard is one of the most difficult tasks I've had as a product analyst. There are several different methods to compare one product to another, but even when you try to measure one against another the features don't always stack up. Benchmark Reviews hasn't been around long enough to have a wide variety of same or past-generation chipset motherboards on hand to test against, which shifts the role of our testing away from who makes the best whatever-chipset motherboard to more of a comparison between this product and other previously-released chipset versions for the same processor and memory.


There is a benefit to being "new" to the review industry however, and this is that we can learn from the mistakes of others and not repeat them ourselves. Additionally, we are able to come up with new idea's of our own and introduce them here. One example of this is how Benchmark Reviews introduced the cost-per-frame analysis of video cards, which showed the price you'll pay for each frame of performance in your favorite video game. In this review, Benchmark Reviews will add to this ingenuity and introduce power consumption results for the motherboards tested.

Testing MethodologyIntel-P45-OCH10-Chipsets.jpg

The Gigabyte GA-EP45T-EXTREME motherboard features two of Intel's latest chipset technologies: the ICH10 Southbridge and P45 Express Northbridge. While testing could have easily be left to a simple "this vs. that" routine, we here at Benchmark Reviews think that this is less than educating. For our tests, each motherboard was overclocked as far as safe limits would allow utilizing the exact same supplemental components. Benchmarks are recorded after each test, and a system shut down and restart followed thereafter. Because the NF790i and X48 also offer PCI-Express 2,0, we also spent considerable time testing the "real-world" difference between the two motherboards with the exact same video card and drivers.
