Our first look at the GeForce GTX 460 showed it to be an impressive product with excellent all-around performance for the price. But what about SLI performance? How does GTX 460 SLI performance compare with a single GTX 480 or GTX 470 in real world gaming? Two 460 cards are now only $80 more than a single GTX 470.

After our first look at the GeForce GTX 460 went live this morning, a great deal of interest was expressed in our excellent forums regarding SLI performance of the new GPU. Of particular interest to our readers are comparisons to a single GeForce GTX 480, and a single GeForce GTX 470.
We did not have enough time to include this in our initial evaluation, but due to demand we decided to roll on and provide some SLI performance evaluation pronto. These are a bit scaled down compared to our normal real world gaming tests, but we think we have what you are looking for.
These tests were performed on the same test system used for our GeForce GTX 460 evaluation.

We have decided to go ahead and use the newly released NVIDIA ForceWare drivers as of 7/12/2010. Our first evaluation used the ForceWare 258.80 Beta driver that NVIDIA made available for us during testing. This morning, NVIDIA made their ForceWare 258.96 WHQL-Candidate driver available for the GPU’s launch, so we used the new driver for these tests.

For the following apples-to-apples performance tests, we used a pair of GeForce GTX 460 1GB video cards in SLI, including one reference card from NVIDIA, and a non-standard design from Galaxy. The galaxy card has a high overclock out of the box, but both video cards were run at reference clock speeds for these tests, which is 675MHz core, 1350MHz shader and 3.6GHz memory. We used a standard-clocked GeForce GTX 480, and a standard-clocked GeForce GTX 470 in all of these tests.
