ATI Mobility Radeon X1800 vs ATI Mobility Radeon X1900 vs ATI Mobility Radeon X1400
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 X1400► remove from comparison
ATI Mobility Radeon X1400 is part of the lower middle class. The performance can be compared with an elder X600, but technically it is a X1300, which is scarcely 100 Mhz higher clocked.
For not very demanding DirectX 9 games the card is sufficient.
Because of the AVIVO video technology the card can help the CPU decode MPEG-2, MPEG-4, DivX, WMV9 and VC-1 video formats.
