It looks like it will replace the Mobile X1800XT.The Amilo Xi 1554 powered by Intel Core 2 Duo T7200 (2.0GHz/4MB Cache), Intel 945PM, and support for RAID. The desktop replacement notebook features 17-inch WUXGA display with 1920x1200 resolution and of course, ATI Mobility Radeon X1900 with 256MB GDDR3 graphics card.
I think they're going to use an X1900GT structure from the sounds of it or possibly an X1900XT 256MB. They say "X1900" so I doubt we'll see some of the "X1950" 256MB derivatives, but, who knows.The Mobility Radeon X1900 it said to have 48 or 36 pixel shader processors and 8 vertex shader processor to outperform the NVIDIA Go 7950 GTX.
