AVIVO for integrated graphics

ATI has officially launched its Radeon Xpress 1250 for Intel Notebooks integrated graphics chipset for Intel Pentium M, Celeron M, Core Solo and Core Duo Yonah and Merom processors. Radeon Xpress 1250 for Intel Notebooks was previously known internally as RS600M. This is ATI’s first integrated graphic chipsets with AVIVO video processing capabilities. Using a Radeon X700 derived graphics core the Radeon Xpress 1250 for Intel Notebooks delivers full DirectX 9.0 compatibility with support for vertex and pixel shader 2.0. ATI doesn’t mention the amount of available pixel or vertex shaders and core clock though.

The integrated AVIVO video processing engine provides hardware acceleration for MPEG-2, MPEG-4, H.264 and WMV9. There’s no mention what H.264 video resolutions the Radeon Xpress 1250 supports, though it may only be limited to 480p like the current Radeon X1300. HDMI 1.1 is supported natively with the Radeon Xpress 1250 for Intel Notebooks while HDCP support requires a separate TMDS transmitter. With the proper TMDS transmitter a Radeon Xpress 1250 for Intel Notebooks solution can support HDMI 1.2. HDMI output capabilities include support for up to 1650Mbps/channel and a 165 MHz pixel clock rate.

In addition to HDMI other video output methods such as VGA and TV-out. There’s also support for dual independent displays for multi-monitor goodness. An integrated TV encoder provides the TV-out capabilities. The internal TV encoder is based on ATI’s Xilleon set top box solution and delivers Macrovision 7.1 copy protection with YPbPr component video output. Resolutions of 480i, 480p, 576i, 576p, 720p and 1080i are supported via component. DVI is also supported with an external TMDS transmitter much like HDMI support.

ATI’s Radeon Xpress 1250 for Intel Notebooks uses a unified memory architecture which allocates some system memory for a video buffer. The minimum amount of allocated memory is 16MB while the maximum is 512MB. As far as system memory goes a maximum of 16GB of DDR2 is supported in 400, 533, 667 and 800 MHz flavors. There’s no mention of dual-channel memory support though.

For manufacturers that wish to implement an external graphics card the Radeon Xpress 1250 for Intel Notebooks has one PCI Express x16 slot that’s fully compliant with PCI Express 1.1a for expansion capabilities. ATI expects manufacturers to pair the Radeon Xpress 1250 with its SB600 south bridge for 10 USB 2.0, four SATA II, one ATA133 ports, high definition audio and PCI.

As the Radeon Xpress 1250 for Intel Notebooks is a notebook chipset it has plenty of power management features. Features such as ATI’s PowerOnDemand, PowerExpress, PowerPlay and new PowerShift features are supported.

Availability of Radeon Xpress 1250 for Intel Notebooks is expected from NEC, though other manufactures might join NEC later on. The Radeon Xpress 1250 for Intel Notebooks is fully compliant with Microsoft’s Windows Vista Premium with aero glass interface. A desktop variant is expected for Intel and AMD processors in the near future.

No one buys motherboards based on their integrated graphics capability. For notebooks, however, I guess this might be slightly worthwhile. I wonder how big the full blown Desktop Replacement crowd is that would even care about graphics power.

The X700 core is an extremely capable core even today. It has more raw power than, say, a GeForce 6200 which is ahead of integrated graphics. I don't deny that integrated graphics are behind and most users looking at cheap notebooks will be in this price range but it would be a good place to start for a budget gaming machine, most users will be happy if they can play the odd game at a reduced detail/resolution setting.

By accident I started Farcry on my Sony SZ1HP which has an Intel GMA950 and a GeForce 7400 (switchable) using the Intel graphics and whilst it didn't look amazing, it was playable at 1024 x 768. The X700 core integrated is a great step to bringing gaming to the masses (of notebook users).

Wrong, we bought mostly NTB's with ATI chipset for last 2 yrs because they have the only useable integrated core.
If someone does not play games does not mean GMA900 is sufficient.
Try some CAD or OGL simulation work and you will understand. Also multi-head support for ATi/NV IGP's is in different league to Intel/SiS IGP's
And no, external GPU is not a solution - it is more expensive, bulkier and sucks more power... while providing pretty little difference for work compared to RS485.
