We test how Dual GPU configuration work out for Nvidia’s famous GTX460 cards.
Today we would be reviewing Nvidia’s ever so famous mid-range card that is the GTX 460 but in SLI configuration. Many people nowadays are going towards the SLI way since it’s relatively a cheaper solution to counter the many high end cards out there. Many gamers now prefer to invest in two mid range cards in SLI setup rather than investing in single high end card to get maximum performance. We will be using a Gigabyte and a Sparkle Calibre card to check how good this SLI setup is.
NVidia launched the 460 to cater the mid-range gamers section and it definitely succeeded in that by launching the 460 which had an excellent price to performance ratio. The 460 has 336 shaders and an effective memory speed of 3600 MHz on most of the cards. Obviously when you put 2 of these babies in SLI have the advantage of extra memory and extra performance enough to take out the 480.
The Multi-GPU concept was initiated by Nvidia under name of “SLI”, but same technology is available in ATi cards too under the name of “Crossfire”. The methodology allows you to combine/add a second or even third similar generation to the one you already have in GPUs. By doing this you effectively try to double, triple or even quadruple your raw rendering gaming performance (in theory). However, it is not essential that adding in more GPUs will always increase performance as they don’t scale linearly. Plus it also depends a lot on the drivers. Ideally though 2 cards scale the best when they are same as is the case with the 460s in discussion.
