SiS offers DDR2-800, PCI Express and no AGP in 2004

Continuing our recent trend of bringing you all the latest in unpublished CPU and Chipset roadmaps we have SiS’ 2004 roadmap.

As usual, we’ll keep it simple and jump straight into the chipsets:

SiS’ P4 chipset roadmap is very similar to Intel’s in that none of their flagship chipsets this year will feature AGP support; SiS is moving very aggressively to PCI Express for graphics. This leaves VIA as the only chipset vendor providing a dual AGP/PCI Express solution for the Pentium 4.

Also unlike VIA, SiS does not include any PCI Express interface other than the x16 slot off of the North Bridge. The SiS South Bridges will initially offer 2 PCI Express x1 slots in April but then by the end of the year we’ll see the 966 South Bridge with support for 4 PCI Express x1 slots.

DDR2-800 support will also be added by the end of the year – assuming memory availability.

For whatever reason, SiS will continue their RDRAM support throughout 2004 and into 2005 with these two chipsets. Other than the memory interface, everything else remains the same as the DDR based chipsets.

SiS’ K8 roadmap is pretty straightforward: we have the 755FX for now and after May the 756 will be the last chipset for Athlon 64/FX/Opteron for 2004. Both of SiS’ 2004 solutions will feature 1GHz HT support, while the 756 will add PCI Express x16 support. Unlike SiS’ P4 chipsets, the 756 will also feature an x4 slot off of the North Bridge – presumably for Gigabit Ethernet PCI Express cards.

What’s interesting to note is that SiS will not have any new Athlon XP chipsets for 2004 – this year will definitely be the year of the Athlon 64.

As we mentioned above, SiS’ 2004 South Bridges will bring PCI Express x1 slots (2 at first, then 4 by the end of the year. In addition to that, starting in March with the 965 South Bridge SiS will offer 4 SATA ports in addition to Gigabit Ethernet support.

SiS does have chipsets with integrated graphics as offerings in addition to all of the aforementioned solutions, if you’d like to read about more mainstream chipsets as well please let us know so we can better tailor the information you.
