Nvidia took advantage of the mass of press descending on Las Vegas for CES to hold a pre-show briefing unveiling Hybrid SLI. This Windows Vista-only technology seeks to exploit systems running Nvidia integrated graphics chipsets and discrete GPUs, allowing the two to work more closely together to improve performance and lower power consumption. Integrated graphics processors (IGPs) have traditionally been confined to budget chipsets, but that won't be the case any longer. Starting this quarter, all new Nvidia chipsets for AMD processors will include an embedded graphics processor. All new chipsets for Intel processors will start getting integrated GPUs in the second quarter of this year.
