SLI Testing - MSI P4N Diamond vs. Asus P5N32-SLI
From the low-quality gaming benchmarks, we're now going to move on to some more demanding tests using a pair of 7800GTs in SLI mode. For these tests, we will only be using the MSI P4N Diamond with the original n4Force-SLI chipset and the Asus P5N32-SLI using the updated n4Force-SLI X16. Basically, what we're looking for here is some evidence that upgrading from 16 to 32 PCI-e lanes for graphics improves performance. We will stick with two of the more demanding graphic engines; Doom3 and Far Cry.
In our testing of two popular games using two 7800GTs in SLI mode, we can see a small, yet favorable increase in frame rates with the P5N32-SLI over the MSI P4N Diamond. It's not quite a monumental improvement, as doubling the number of lanes has only increased performance by 4-11 percent.
