The M770S also sports an SiS M672 graphics processor instead of the M770K's ATI Radeon X1270. Otherwise, the two laptops are nearly identical as both sport a 17" LCD display, support for up to 4GB of DDR2 RAM and a 7-in-1 media card reader.
The M770S' Intel Celeron and Core 2 Duo processors offer competent everyday and media performance while offering better battery efficiency than more powerful processors. Its SiS M672 graphics processor provides the M770S with the ability to handle high definition media files at 720p. Meanwhile, the M770S' 7-in-1 media card reader allows it to interface directly with most popular media card types without the need for an external adapter.
