...featuring ATI Radeon Xpress 1250 graphics

HKEPC has revealed further details on the upcoming AMD RS690 chipset. The new chipset has been named AMD 690G and falls in line with AMD’s new chipset naming scheme. RS690 was previously expected to be named Radeon Xpress 1200 before AMD and ATI merged. It appears the AMD 690G is nearly finished with the latest stepping being A12. Manufacturing of the AMD 690G will be done by TSMC on an 80nm fabrication process.

The upcoming AMD 690G is expected to feature a Radeon X700 derived graphics core that’s been renamed ATI Radeon X1250. Features of the integrated ATI Radeon X1250 include full support for DirectX9, shader model 2.0 support and AVIVO. The AVIVO video engine of the Radeon X1250 supports hardware accelerated H.264 and VC1 video processing for Blu-ray and HD DVD playback.

In addition to the standard RS690 there are four other variants including the RS690C, RS690T, RS690M and RS690MC.The RS690C will be the base chipset and lacks an integrated TMDS transmitter while the RS690T is the high-end variant with support for external video memory which is referred to as Sideport Memory. The RS690M and RS690MC will be targeted towards AMD Turion powered notebooks.

Other notable features of the AMD 690G include support for one PCIe x16 and four PCIe x1. The AMD 690G is expected to pair up with AMD’s SB600 south bridge for SATA 3.0Gbps and high definition audio support. According to the article, the AMD 690G will be pin compatible with the previous Radeon Xpress 1100 and may possibly be able to use the same PCB.

Expect AMD 690G based motherboards to arrive in early 2007 with varied pricing depending on which RS690 variant is employed.

Yeah, but basically the Radeon® Xpress 1250 for Intel Notebooks is the same chipset this is, just for Intel instead of AMD.

If RS690 is really pin compatible with RS48x (already AM2 boards out on this chipset), and ATI already has had Radeon® Xpress 1250 for Intel Notebooks out in production systems (which they do), then really how hard could it have been to put out RS690???

Don't get me wrong, I'm really happy the info is starting to flow on the major sites, as I'm taking that to mean I can finally buy about 4 of these things to complete some builds (one of which is my own), but Man, one's got to start wondering just what the heck the ATI folks were thinking on delaying this SO LONG?!?!?

Looking at all the 61x0 series PC's in the store this holiday season, that's a whole heck of a lot of lost sales there......too bad they couldn't have been RS690 systems... :(

Sorry, here's the link to the spec page for the Intel version of this:
