SiS today announced the launch of its newest North Bridge for the Intel®
Pentium® 4 CPU, the SiS656. The SiS656 is the first SiS P4 North Bridge to
support the new PCI-E standard and will offer vendors the option of pairing it
with the new SiS965 South Bridge that also supports PCI-E. With a complete
lineup of next-generation ready chipsets for PC and notebooks, SiS offers
vendors a complete PCI-E solution.

Memory-intensive digital multimedia applications will also benefit from the
support for dual channel DDR2-667 and DDR400 offered with the SiS656 chipset. 4
DIMMS are supported, with a huge 1 GB per DIMM of RAM, for a total of 4GB of
system memory supported. The SiS656 employs an extremely flexible dual-channel
memory architecture that supports all types and capacities of memory modules
while retaining full dual-channel functions at a memory bandwidth up to 10.6GB/s
with DDR2-667 modules and 6.4 GB/s with DDR400 modules. The SiS656 also supports
the new PCI Express x16 interface, which provides an 8GB/s bi-direction transfer
rate, compared with the current AGP 8x standard of 2.1GB/s. Game developers,
graphics card manufacturers and gamers themselves see this move to PCIE 16x as
the next evolutionary step for PC gaming, which will revolutionize the gaming
industry.

Combined with SiS latest South Bridge Chipset SiS965, the SiS656 offers
buyers a formidable combination that is ready for the next generation of
peripheral devices thanks to PCI-E support. The SiS965 supports PCI-E x1,
gigabit LAN, 8 USB 2.0 ports, AC 97 7.1 channel sound, 4 SATA and 4 PATA. The
SiS965 also supports Multiple RAID disk array modes in RAID0, 1, 0+1 and JBOD.
Vendor samples are available now, with motherboards based on the SiS656 due to
hit the market in May.

The new PCI Express hardware interface standard promises to revolutionize
personal computing. PCI Express replaces the old PCI interface, which has been
in place for the past decade, in favor of a higher bandwidth PCI Express
interface which will be used by the next generation of graphic cards and WLAN
cards. The main advantage of PCI Express is that it provides up to nearly 2
times the bandwidth compared with the current PCI slots, with data transmission
possible at 2.5 GHz. Particularly exciting is the PCI Express graphic interface,
with twice the available bandwidth of the current AGP 8x interface, promising an
entirely new standard in 3D applications.

The SiS656 is ready for tomorrows bandwidth-intensive applications today:
Advanced HyperStreaming™ technology, delivering even higher overall performance
in comparison with HyperStreaming™ technology, offers more advanced data
processing that maintains the best resource utilization across multiple
operating environments. Moreover, SiS MuTIOL® 1G technology, embedded in SiS656
chipset, ensures the smoothest data transfer between South and North Bridges and
the fastest bus architecture available on a desktop PC chipset.

support for dual channel DDR2-667 and DDR400 offered with the SiS656 chipset. 4

When combined with the raw processing might of the Intel® Pentium® processor
with Hyper-Threading technology, the SiS656 makes a formidable platform for
digital and home entertainment. With Hyper-Threading technology, the processor
is able to execute two threads of a program at the same time, making it the
ideal choice for a digital multimedia entertainment hub, where demanding
applications such as streaming audio and video require an advanced processor.

SiS is proud to offer our customers a Pentium 4 PCI Express solution, said
Michael Chen, President and CEO of SiS. With the SiS656, SiS gives Pentium 4
users the benefits of advanced PCI Express technology. Vendor samples are
available now, with motherboards based on the SiS656 due to hit the market in
May.
