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.
The ATI Mobility Radeon X1450 dedicated graphic card for laptops has an improved relation of performance to current consumption compared with its predecessor ATI Mobility Radeon X1400. Both are part of the lower middle class. The performance can be compared with an elder X600, but technically it is a X1350.
Because of the AVIVO engine the card can support the CPU in decoding MPEG-2, MPEG-4, DivX, WMV9 und VC-1 videos.
