ATI Mobility Radeon X1700 vs ATI Mobility Radeon X1450 vs ATI Mobility Radeon X1900
ATI Mobility Radeon X1700► remove
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.
ATI Mobility Radeon X1450► remove
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.
ATI Mobility Radeon X1900► remove
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.
