SiS makes questionable chipset claim

— 12:05 PM on February 23, 2005

SiS is circulating an interesting press release claiming that its SiS756 is the only Athlon 64 chipset that supports both PCI Express x16 graphics and a 1GHz HyperTransport link.

Taipei – February 23, 2005 --- Silicon Integrated Systems (SiS) today announced that a series of tests on the SiS756 PCI Express chipset show that the SiS756 can enable all 16 of its PCI Express lanes and support the powerful and efficient HyperTransport 1GHz high speed transfer capabilities. The SiS756 is currently the only AMD64 platform northbridge chip that fully supports PCI Express x 16 and HyperTransport 1GHz specifications.
SiS backs up its claim with a screenshot of NVIDIA's graphics card driver and SiSoft Sandra's Mainboard Information app, which show PCI Express x16 graphics and a 1GHz HyperTransport link. We can replicate that screenshot on our XPC SN25P test system, which uses NVIDIA's nForce4 chipset, which makes SiS's claim look more than just a little dubious. We'd like to see more proof from SiS than a simple screenshot, especially since we can replicate the screenshot on a competing chipset.
Like what we're doing? Pay what you want to support TR and get nifty extra features.
