SiS launches SiS648MX and SiSM661MX Chipsets for Pentium M

After the announcement that they have obtained a Pentium M license SiS directly launched 2 new chipsets for the mobile Pentium M processor. The SiS648MX and SiSM661MX wil be used in wireless mobile applications.

With 400 MHz System Bus, the SiS648MX supports memory capacity up to DDR 3G and the AGP 8X graphic interface. In conjunction with wireless network chipsets, the SiS648MX is also capable of providing customers with the ideal solution for wireless networks. SiS648MX supports the HyperStreaming™ Engine technology, with emphasis on upgrading the overall performance of PC systems. Through all-inclusive hardware management and system resource distribution, it effectively manages CPU, Front Side Bus, south-/north-bridge chips, memory controller, graphic interface and each I/O peripheral, enhancing PC function to the maximum while fully demonstrating the unparallel efficiency of the Intel® platform. Taking advantages of power management function of the Intel ® Pentium ® M, the SiSM661MX delivers excellent operating environment with low power consumption and high system efficiency. Coupled with SiS963 south bridge chipset, the chipsets provide a transmission bandwidth up to 1G between the north and the south bridges. The SiSM661MX also employs the unique Real256E graphic engine with the exclusive Ultra-AGPII TM technology, which provides lower signal latency and offers greater transmission bandwidth between the built-in graphic engine and the memory controller, which provide excellent operating environment and outstanding display quality for heavy gamers and digital video players. The flexible dual-view application allows the screen to be simultaneously displayed on a CRT, TV or LCD monitor, and supports a maximum resolution of 1600x1200 in the full screen UXGA display. Designed exclusively for wireless broadband, SiS162 is the only wireless LAN (WLAN) chipset currently on the market that supports USB 2.0 interface of 480Mb/s high speed transmission function. It offers data transfer rates of 1, 2, 5.5, and 11 Mb/per second, which is compliant with the 802.11b wireless local network (WLAN) standard. Its minimal size of the wireless communication module achieved through advanced manufacturing process effectively lowers the overall manufacturing cost.

The difference between the 648MX and the M661MX is that the M661MX has an integrated graphics solution and the 648MX not.

The mass production of the SiS648MX and SiSM661MX will start in Q4 2004. The first motherboards based on these chipsets will be available in early 2004.
