At X-bit Labs they’ve published a massive article on nVidia’s graphics card technology SLI. Many of our readers know very well what SLI is. You others we can briefly summarize it to allowing you to run two identical graphics cards in the same computer to achieve an increase in performance of up 100%.
As with all technology SLI is far from perfect, something we’ve also experienced in our testlab.
In X-bit Labs’ article they walk you through the history of SLI and the different type of techniques that’s used by the participants. But they take an even closer look at nVidia’s SLI-technology both theoretically and practically through a wide variety of tests.
The results are varying and as we have experienced as well the SLI-technology is both impressive and frustrating from time to time.
“That said, we could agree with NVIDIA’s claims about a super-high efficiency of SLI technology if it were not for one problem. SLI does not work with all games. In many gaming applications there was no performance gain whatever or there even was a negative effect from enabled SLI. In some cases enabling SLI made the system unstable, or a game just would not start up.”
We have in our testlab been testing the SLI-technology for a few months and we still haven’t managed to get everything to work the way it should. We hope to have parts of our material ready in a few weeks offering our view on nVidia’s promising graphics card technology.
