Well, looks like according to OCWorkbench the launch date for AMD 690G will be Feb. 9th, 2007:
Official launch date of AMD 690G (ATi RS690)
I'm probably wrong on this, but the more I think about this, I'm thinking this chipset was intentionally delayed. The reason I say this is because, other than using an X700 core and supporting HDMI and HDCP, and also using the SB600 southbridge, this chipset appears to be pretty much the same as the ATI RS48x.
Knowing that this chipset if it was released (at least) 4+ months ago when it was supposed to have been, nVidia would have taken a beating in the integrated video AMD segment, I've got to think nVidia went to AMD and said, Look, we've been doing business for a long time, you have nothing for your 4x4, and we've got tons of nForce 61x0 out there...
...you get ATi - who you're about to aquire - to hold off on RS690 until our 61x0 inventory is consumed and we're close to being able to release a competing part (and they are close to having their new integrated DX9 and DX10 chipsets ready now), and we'll help you out on 4x4 (and who knows what else).
I mean we're talking millions of dollars on all sides, not to mention priorities...I just cannot imagine that it would take someone like ATI (and then AMD) so rediculously long to take their current chipset, upgrade it to X700 level, have it support HDMI and HDCP (RS48x already supported DVI, so come on, not that hard), and have it talk to their new SB600 southbridge (again, should be very easy)...truly, while this is going to be a great integrated video chipset - the best out if it ever actually gets here - there's just no reasonable way it could have taken this long.
Really makes me wonder now, What does nVidia have up its sleave for the integrated video AMD world....
