Intel is preparing a new chipset for low-end motherboards - the G41. FUD Zilla says this chipset will be released in Q4 2008 and claims it's a stripped down version of the G43 with single-channel memory, no HDMI and no hardware video acceleration.
G45 is the top of the offer, and it has full video decoding acceleration including MPEG2, VC1 and AVC. This is Intel's first DirectX 10 chipset.
The chipset supports HDCP, HDMI, DVI and Display Port and PCIe 16X graphics. Moreover it supports two memory channels with up to two dims per channel, it supports Vista Premium logo, ICH10 R and Intel remote wake technology.
G43 has single channel memory support and it misses hardware decode acceleration but the rest looks the same like G45.
G41 actually looks very similar to G43 as it doesn’t have a hardware video acceleration engine and it also has single channel memory. It shares the same X4500 graphics engine but it lacks HDMI support. It can support DVI or Display Port and it also misses out the remote wake technology.
