Intel today at Computex revealed four series chipsets for its desktop processor lineup. The four chipsets introduced are G43 Express, G45 Express, P43 Express and P45 Express. The G45 chipset will include the new integrated graphics accelerator X4500HD, which will make the chipset capable of full hardware acceleration of most HD video formats up to 1080p. The X4500HD will also improve 3D graphics and will add support for DirectX 10 and OpenGL 2.0. The chipset will have support for the DisplayPort and HDMI outputs. The G43 Express chipset is basically a scaled down version of G45 chipset, most of the features will remain same on both the chipsets. The P43 Express and P45 Express will come without integrated graphics card and will support dedicated graphics cards. The major difference between the two chipsets is that the P45 will support two PCI Express 2.0 slots for dual video cards (for high-end gaming) where as P43 will support single PCI Express slot. All the new chipset are designed to support DDR3 memory of up to 1,066MHZ and will have a low-power mode that significantly drops power use when paired with the new 45nm processors. The chipsets should start shipping in Q3 2008.
