Short-term AMD IGP chipset roadmap
ATI RX690, RS690T/DC and NVIDIA MCP61

DailyTech has received an AMD roadmap that highlights upcoming Socket AM2 chipsets from ATI and NVIDIA. According to AMD’s June 2006 roadmap ATI has a new discrete graphics solution that should arrive in Q3’06. Currently known as RX690, the new chipset will have one PCI Express x16 graphics slot. RX690 lacks the capability to divide the 16 PCI Express lanes to two PCI Express x8 slots. There’s no mention if CrossFire will be supported with RX690 but it seems very unlikely. Nevertheless the RX690 supports six PCI Express lanes instead of the four lanes supported by current Radeon Xpress 1100/1200, CrossFire Xpress 1600 and CrossFire Xpress 3200 chipsets. RX690 based motherboards will have access to a variety of PCI Express based south bridges including ATI’s SB460 and SB600.

There has been plenty of news regarding ATI’s next generation RS600 integrated graphics core-logic for Intel processors but not much has been published on the AMD variant—RS690. Roadmaps show ATI will offer two RS690 variants to motherboard manufacturers. The plain RS690 will use shared memory architecture and support DirectX9 and SM 2.0 with its Radeon X700 derived graphics core. Other notable features include one PCI Express x16 slot, six additional PCI Express lanes and integrated HDMI with HDCP compatibility. Although AMD K8-based processors have integrated memory controllers that drastically reduce memory access latency, it reduces integrated graphics performance. ATI will have a second RS690 variant that addressed shared video memory latency issues. The RS690T/DC will support a local-frame buffer which is essentially dedicated video memory attached directly to the integrated graphics core, removing shared memory latency issues.

Last on the AMD roadmap is the upcoming NVIDIA MCP61 integrated graphics chipset. The single-chip core-logic will have a GeForce 7 series graphics processor with support for PureVideo. PureVideo acceleration will be limited to standard definition video playback which leads us to believe the MCP61 is the GeForce 6100 successor. The integrated graphics core will also support VGA and HDMI video outputs, though there’s no mention of HDCP compliancy. MCP61 will not have an integrated TV encoder for S-Video, composite and component video outputs. Additional supported features include 10 USB 2.0, four SATA II ports, one Gigabit and high definition audio.

NIce IGP's

I am currently running the Nvidia 6100 IGP for the AMD 939 Platform and I love it. I love how I do not need an extra video card in order to display video. I just wish the video capabilities were stronger so I could use it for mild gaming (not so good at UT2004). The new chipset from ATI sounds nice as it has a stronger IGP and also addresses the memory latency issue by providing integrated memory for the IGP.
Nvidia's also sounds nice, but my next IGP will have to come with a DVI port as it improves the image quality of my LCD monitor. I guess I will just wait awhile until I get to upgrade again...by that time AM2 won't be around much longer I am guessing.

If you have even a "mild" interest in gameing, you should have "zero" interest in IGP...save the money for your next "upgrade, and get a basic discreet graphics card instead.

IGP is not designed for gaming. It's designed for oem (ie office work, and casual home users, etc...). I've found the cutting edge IGPs are usually great for playing 5yr old games, unless you're into that sort of thing :D

Perhaps "mild" was not a proper description of my PC gaming experience. I used to have a 7800GT but needed the money for school, that card was a huge upgrade from my 9800 Pro. You are correct that the IGP's are not for gaming, but I wish that they would create a board with a mid-range IGP, even a last generation example would be sufficient...like sticking a 6600GT on board or something. Too bad that won't likely happen.
I spend the majority of my time catching up on games I have missed out on for my PS2 as it is still fun to play. My PC gaming days are pretty much non-existent because I would prefer playing with real people in the room and I don't have friends that want to create a LAN, although I did do FFXI with some friends and partying with them was fun in the same room. But my PS2 gives me plenty of fun for now.

Exodus220, you are not alone. I am definitely noticing a trend of people heading back to the console for gaming. Doesn't it make like so much easier and headache-free. No driver issues, no video issues. I true like not having to worry if my graphics card will support the game. I know when I buy a ps2/xbox game it will just play.

I totally agree with the idea of adding a mid-range IGP. While I am not a gamer, it would help create more value in the budget lane. I like the fact that with mid-range IGP, you get better video performance (I am not talking gaming here). Usually they add a little high-definition acceleration, some color correcting and a host of other stuff. It sure would be nice to totally bypass a discrete graphics card and have an all-in-one solution.

I was just checking and Asus is very close with their M2NPV-VM Geforce 6150 motherboard. This board is fully loaded with everything except native HDMI. But that is easily fixed with with a DVI-to-HDMI dongle/cable. Only if they would bump up the graphics core to a 7600 and there you have, no holds bared PureVideo support. Not only that, it has headers for coaxial and digital SPDIF output.
