ATI Mobility Radeon X1400► remove
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.

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.
