ATI Mobility Radeon X1800 vs ATI Mobility Radeon X1900 vs ATI Mobility Radeon X1700
ATI Mobility Radeon X1800► remove from comparison
The ATI Mobility Radeon X1800 is a reduced version of the X1800XT. The performance was at the time of arrival still very good. The card was constructed for big laptops (DTR) as it had a high current consumption and heat emission. All games of 2006 were fully playable in high details with the X1800.

At the moment, the ATI Mobility Radeon X1900 is the top video card from ATI for notebooks. The performance is better than X1800 / 7900GS. Due to heat problems the marketing was delayed but now this problem seems to be fixed. According first reports it is about 12% faster than a X1800 (Alienware configurator). The performance in our tests was about as fast as the Nvidia 7900 GS.
The X1900 is a enhanced X1800 produced in 80nm. The 36 Pixel Shader count like 12 pipelines from Nvidia cards.
The AVIVO technology allows the chip to accelerate H.264, DivX, MPEG-2, MPEG-4, WMV9, and VC-1 videos.
ATI Mobility Radeon X1700► remove from comparison
The graphic card ATI Mobility Radeon X1700 for notebooks is the successor of the ATI Mobility Radeon X1600. It achieves a higher performance with same current consumption due to strained Silicon. Due to additional pixel- and vertex-pipelines the performance is clearly above the X1600 and therefore sufficient for all games in 2006 with medium and high settings. The direct competitor ought to be NVIDIA GeForce Go 7700 but the performance was compareable to the 7600.
Also a XT variant with a probably higher clock (codename M66-XT) was planned but did never arrive.
The Avivo video engine helps the cpu in decoding (HD) videos.
