If you're planning on purchasing an Intel system with onboard video, you'll soon have an extra choice. nVidia will launch two new chipsets shortly, the 9300 and 9400 series. The chipsets are designed for socket 775 and compatible with all Intel processors featuring an FSB of up to 1333 MHz, this includes the current 45nm generation. Where Intel utilizes a seperate north- and southbridge, nVidia has integrated everything with the 9300 and 9400 series.
Overview of the 9400 chipset, image source: Computerbase
Apart from a PCI-Express 16x 2.0 connector and support for DDR2-800 and DDR3-1066, the chipset also has all functionality of the southbridge. It's able to handle 6x SATA, 5x PCI and up to 12x USB. Most interesting are the graphics improvements: apart from DX10 and Hybrid SLI, the chipset's integrated GPU is also compatible with CUDA, the software that allows the shaders to be used for multiple calculative tasks other than processing graphics.The graphics chip in the 9300 and 9400 chipset features 16 shader units. The difference between the two is the clock frequency: the 9300 is clocked at 450/1200 MHz for the core and shaders, the 9400 at 580/1400 MHz, again for the core/shaders.
The chipset also supports outputs such as VGA, DVI, HDMI and Displayport. 7.1 audio and Gigabit LAN are also part of the features. The first motherboards based on the new 9300/9400 chipsets have already been announced by ECS, MSI and ASUS. The new S775 motherboards should become available shortly.
