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 first game that was tested was Aliens Vs. Predator. The ASUS P8P67 Deluxe was able to scale to 90.7% at 1280×1024 and 92.3% at 1920×1080. The ECS P55H-AK was able to scale to 89.3% at 1280×1024 and 90.6% at 1920×1080. In Aliens Vs. Predator the ASUS P8P67 Deluxe was able to scale better, though the ECS P55H-AK did have slightly better performance. Although, in past reviews I have noticed that there is very little performance difference between processors.
Our second gaming test that we wanted to test NVIDIA SLI performance is Metro 2033. In Metro 2033 the ASUS P8P67 Deluxe was able to scale to 75.1% at 1280×1024 and 70% at 1920×1080. The ECS P55H-AK was able to scale to 31.2% at 1280×1024 and 40.2% at 1920×1080. The ASUS P8P67 Deluxe was able to scale quite a bit better than the ECS P55H-AK at all resolutions.
Our final test for NVIDIA SLI scaling is S.T.A.L.K.E.R.: Call of Pripyat. At 1280×1024 the ASUS P8P67 Deluxe was able to scale to 174.2% of the single card performance and at 1920×1080 we saw scaling of 184.2% of the single card performance. The ECS P55H-AK saw an improvement of 134.7% at 1280×1024 and 158.8% at 1920×1080 when compared to the single card performance numbers.
When it comes to performance scaling with NVIDIA’s SLI technology the ASUS P8P67 Deluxe was a clear winner as it dominated the field in both Metro 2033 and S.T.A.L.K.E.R.: Call of Pripyat. Aliens Vs. Predator was a closer match for the two systems but the ASUS P8P67 Deluxe still came out ahead at both resolutions. Join us on the next page where we are going to add the ASUS P8P67 to the mix for our AMD CrossfireX scaling test.
