What are the main differences between the 915GMS Express Chipset used on the L-Series Tablets PCs 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). 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 LS800, while the older 855GME chipset supports the previous-generation 333MHz DDR memory. The 915GMS chipset includes the IntelĀ® 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.
