Intel's GMA 3100 and 3500 were not too impressive at the time, but
the company promises big improvements in the GMA X4500 HD, debuting in the G45 Express chipset. The G45 Express chipset is a step up from older Intel-based budget chipsets. It
supports front-side bus speeds up to 1333 MHz,
PCIe 2.0,
DDR2 800 or DDR3 1066, and a whole mess of SATA ports through the ICH10 controller hub. The DG45ID in particular is a DDR2 motherboard, so that somewhat limits our memory bandwidth. It's pretty small as MicroATX boards go. Note that this motherboard does not support the really high-wattage Intel processors;
the fastest supported chips are the quad-core Q9550 or the dual-core E8500.
The
GMA X4500 HD graphics in the G45 chipset
is a relatively minor upgrade to the old GMA 3100/3500 in previous boards. It's a very similar part, only with 10 unified shader processors instead of 8, running at a higher clock speed. Intel claims that the GMA X4500 HD supports DirectX 10. It's far too slow to be usable even in the most forgiving of DX10 titles, and even with all the details turned way down. So, a big part of the GMA X4500 HD integrated graphics processor is supposed to be it's great video engine -
full 1080p and acceleration for Blu-ray codec standards like MPEG-2, VC1, and H.264 (also known as AVC in some circles).
- Hardware video acceleration worked on titles that used MPEG-2 or VC1, with CPU utilization usually in the 20–35% range.
- Hardware AVC decoding works and CPU utilization in AVC-encoded Blu-ray titles dropped to around 20–40%.

Čipset, čiji IGP je prema pompoznim najavama, trebal (baš kao Intel G35 vs. AMD 690G slučaj) slomiti AMD HD 3200/3300, te GeForce 8200/8300 rješenja u svakom pogledu.
