What are the main differences between the 915GMS Express Chipset used on the LE1600 and the 855GME Chipset used on the M1400 Tablet PC?
A. The 915GMS chipset offers a vast improvement in video performance (41% improvement in 3DMark score in one Intel benchmark analysis) and is equipped to support Microsoft’s Longhorn operating system when it launches in the future. The 915GMS chipset was designed to support the new Sonoma architecture and a higher-performance memory interface, while the 855GME chipset was designed at the time that the previous-generation Dothan CPU architecture was introduced. The newer 915GMS chipset supports the new faster 400MHz DDRII memory available on the LE1600, while the older 855GME chipset supports the previous-generation 333MHz DDR memory. The 915GMS chipset includes the Intel® GMA 900 Integrated Graphics controller with 128MB of video RAM, whereas the 855GME uses the Intel Direct AGP Integrated Graphics controller which includes only 64MB of video RAM.
