NVIDIA SLI: Linux vs. Windows

Posted on Thursday, Sep 27 2007 @ 07:20 CEST by Thomas De Maesschalck
It is going on two years since support for Scalable Link Interface (SLI) was introduced into NVIDIA's Linux binary display driver. This support had come a year after it was officially launched and supported by the Windows ForceWare display driver. As we had seen at the end of 2005 with two GeForce 6 graphics cards in SLI, its performance was very sluggish, and there were a number of problems to be found with Linux SLI. While we have routinely tested new NVIDIA graphics cards under Linux SLI internally, there hasn't been much to report on as the experience has been very foul.

However, things have changed recently and with the recent NVIDIA 100.14.19 display driver release using GeForce 8 hardware -- we finally have some modest numbers to report on in a Linux SLI configuration. Linux SLI is still far from perfect, but in this article we've used two GeForce 8600GT graphics cards in an SLI configuration under both Linux and Windows to compare the single and dual GPU performance under both operating systems.
