Like most integrated graphics implementations, the X4500HD carves itself a slice of system memory, in this case via the G45 Express’s dual-channel memory controller. You can feed multi-channel LPCM audio over HDMI, too-something even AMD’s beloved 780G can’t hack. The chip can simultaneously drive up to two digital displays via DVI, HDMI, and DisplayPort outputs. One of the more impressive elements of the G45’s graphics component is its robust output capabilities. These necessary evils are essential to protect end users from the dangers of fair use, or something. Those same commercial Blu-ray titles tend to be encrusted with a thick layer of DRM, so it’s no surprise that the X4500HD offers support for both HDCP and the Protected Audio/Video Path. We’re not entirely sure how useful those features will be given the quality of commercial Blu-ray releases, though. Like AMD and Nvidia, Intel also has its own collection of de-interlacing and post-processing schemes to enhance HD video quality. 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. The X4500’s HD moniker actually means something, denoting support for Blu-ray decode acceleration. We’ll find out for sure in a moment.įortunately, there’s more to the G45 Express’ graphics core than added horsepower. The X3500’s gaming performance failed to impress, which doesn’t leave much room for optimism that the X4500HD will be a big improvement. Intel has added a couple of cylinders and slapped on a turbo, but we’re still dealing with the same tired car analogy. 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. While the individual shaders cores haven’t changed much for the X4500HD, there are two more of them, for a grand total of 10. 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. The chipset’s north bridge component houses its graphics core: the Graphics Media Accelerator X4500HD.
Integrating graphics functionality is the G45 Express’ raison d’être, so that’s the best place to start. But can Intel really compete with the graphics specialists on their home turf? There’s only one way to find out. On paper, the G45 Express certainly looks like it should be able to run with the new IGP order.

These graphic cores have also been bestowed with dedicated video processing engines that serve up silky Blu-ray playback with even an Econobox sub-$100 CPU. AMD and Nvidia are using functional blocks ripped from their high-end GPU architectures, assuring not only broad compatibility with games, but surprisingly adequate performance. Lately, however, integrated graphics chipsets have enjoyed a renaissance. Older integrated graphics solutions simply didn’t have the graphics horsepower to run games-not just at acceptable frame rates, but at all-and they didn’t offer much in the way of video playback acceleration.

At best, we only considered the IGPs of yesteryear as platforms for the next PC we’d build our mothers or corporate desktops we’d deploy to the masses of slack-jawed users in our domains. There was a time when enthusiasts had little interest in integrated graphics chipsets.
