Since the Intel P67 is a brand new chipset, we decided to change a few things up in our testing. The next two pages are all about the scaling of multiple GPU’s in our systems. First off, we are going to test how well the P67 chipset scales multiple NVIDIA cards. In order to do this we contacted our friends over at GALAXY and they were kind enough to send over a pair of NVIDIA GeForce GTX 460 1Gb graphics cards that are available in a two card SLI kit.
The GIGABYTE P67A-UD4 put its game face on in Aliens Vs. Predator. At both resolutions that we test, the GIGABYTE P67A-UD4 outperformed all of our other boards. At 1280×1024 the P67A-UD4 was able to hit 69.9FPS which is 1.7% faster than the ECS P55H-AK system and 2.9% faster than the ASUS P8P67 Deluxe. Cranking the resolution up to 1920×1080 we see very similar results. As far as the SLI scaling goes, at 1280×1024 we saw a gain of 92% and at 1920×1080 we saw a gain of 93.6%.
The GIGABYTE P67A-UD4 is putting on a solid show in Metro 2033, though it did slip slightly and was edged out for the top spot in overall performance by the MSI P67A-GD65. The MSI P67A-GD65 saw a gain of 78% compared to the 74.2% gain of the GIGABYTE P67A-UD4. The ASUS P8P67 Deluxe fell between the two boards with a gain of 75.8% at 1280×1024. At 1920×1080 the MSI P67A-GD65 saw a gain of 72%, the GIGABYTE P67A-UD4 improved by 70.7% while the ASUS P8P67 Deluxe is sitting at 70%.
Our final test for NVIDIA SLI scaling is S.T.A.L.K.E.R.: Call of Pripyat. The GIGABYTE P67A-UD4 dropped down another spot in S.T.A.L.K.E.R.: Call of Pripyat. When running the benchmark at 1280×1024 the GIGABYTE P67A-UD4 improved by 67.7% while the MSI P67A-GD65 gained 71.6% and the ASUS P8P67 Deluxe improved by 74.2%. Increasing the resolution of the benchmark to 1920×1080 yields similar results. The GIGABYTE P67A-UD4 saw an improvement of 76.2% while the MSI P67A-GD65 improved by 84.4% and the ASUS P8P67 Deluxe jumped up by 84.1%.
