Mobility Radeon 9100 IGP

RS300M, or Mobility Radeon 9100 IGP, is the version of chipset that will be aimed as a mobile platform. There is not too much more that can be said about RS300M that hasn't been said about RS300 since essentially they are the same - in fact, some might say that physically they are exactly the same chip.

If RS300 and RS300M were the same chip, they will of course have slightly different properties for their respective target markets. For starters, the RS300M is not just a chipset for Pentium4-M, but also the newer Pentium M laptop CPU. There is also integrated support for LVDS displays up to 2048x1536, on top of the display types already mentioned from RS300. Also the chipset integrates Intel's Speedstep CPU clocking functionality with ATI's own PowerPlay features for full power control management.

RS300M's similarity to RS300 is far from any bad thing though, since all the elements present in RS300 are present in RS300M. Not only is the integrated video performance and features still there, but also the full dual channel DDR400 memory interface and AGP8X support, meaning this is the first mobile chipset to support these features and clearly the system performance could easily approach that of a desktop system. ATI's Flexfit system is still in place so that higher end ATI mobile video chips can be utilised with this chipset -- a system such as this utilised in conjunction with an M10, Mobility Radeon 9600 PRO could make for exceptional gaming performance on a laptop system.

Conclusion

ATI's emphasis with RS300 is still very much of low cost. Clearly, though, the chipset configuration signals itself as a much higher performer than IGP340 and one that might appeal to a broader range of consumers, especially if ATI gain an 800MHZ FSB license for the chipset. Despite the higher performance credentials though, ATI expect the very low end boards, with minimal features, to be introduced at as little as $65.

From the quick performance numbers we took the integrated graphics performance seems to be quite capable of playing current titles at reasonably low resolutions even with Pixel Shaders enabled - certainly this will be a big step up from Intel's i845 or i865 gaming performance. We'll have a more complete integrated graphics and system performance review once samples are readily available.
