Second-generation PCI Express slot for discrete graphics upgrades? Check.Proven south bridge with all the feature boxes, er, checked? Check.Front-side bus that hooks into the spoils of Intel’s Core 2 processor lineup? Bonus!.On paper, the G45 Express certainly looks like it should be able to run with the new IGP order. Integrating graphics functionality is the G45 Express’ raison d’être, so that’s the best place to start.īut can Intel really compete with the graphics specialists on their home turf? There’s only one way to find out. The chipset’s north bridge component houses its graphics core: the Graphics Media Accelerator X4500HD. This GPU is an extension of the GMA X3500 architecture found in Intel’s older G35 Express chipset, bringing the X4500HD DirectX 10-class unified shaders with support for Shader Model 4.0 and OpenGL 2.0. While the individual shaders cores haven’t changed much for the X4500HD, there are two more of them, for a grand total of 10.
These cores are running faster, too, with Intel cranking their clock speed from 667MHz in the X3500 to 800MHz in the X4500HD.Īs far as the 3D pipeline is concerned, the X4500HD is a mildly hopped-up X3500. Intel has added a couple of cylinders and slapped on a turbo, but we’re still dealing with the same tired car analogy. The X3500’s gaming performance failed to impress, which doesn’t leave much room for optimism that the X4500HD will be a big improvement. We’ll find out for sure in a moment.įortunately, there’s more to the G45 Express’ graphics core than added horsepower. The X4500’s HD moniker actually means something, denoting support for Blu-ray decode acceleration. Intel makes use of both fixed-function logic and the X4500’s shader processors here, assisting with nearly every step in the decode process for the MPEG2, VC-1, and AVC/H.264 video formats. Like AMD and Nvidia, Intel also has its own collection of de-interlacing and post-processing schemes to enhance HD video quality. #Intel g45 g43 express chipset caracteristicas windows#.#Intel g45 g43 express chipset caracteristicas Pc#.
