Conclusions

SiS 672FX is simply a joke. This is probably the worst chipset for the Intel platform available today.

Not only its graphics engine provides a very low performance: you won’t achieve the same performance level of mainstream motherboards by installing an add-on video card on it. For example, on Quake 4 a MSI P35 Platinum with a GeForce 8800 GTS installed was 36% faster than the reviewed board with the same video card installed. This is simply unheard of.

The major flaw of this chipset is its memory controller, as it does not work under dual channel mode and seems to be badly designed.

SiS chipsets are the cheapest around, making motherboards based on their chipsets also the cheapest. But due to the low performance offered by SiS 672FX we strongly recommend you against buying a motherboard based on SiS 672FX. Pay a little extra and buy any other motherboard.

Just to put things into perspective with SiS 672FX our Core 2 Duo E6700 with 1 GB DDR2 achieved a performance WORSE than a Pentium 4 2.4 GHz with a low-end motherboard with on-board video (VIA P4MA Pro 533 motherboard, VIA P4M266A chipset) with 512 MB DDR on Quake III (53 FPS vs 46 FPS). On 3DMark2001 SiS 672FX was faster than this Pentium 4 configuration, however on this program the same Pentium 4 2.4 GHz using an Intel 865G-based motherboard was 18% faster. This is simply ridiculous: what is the point of buying a Core 2 Duo and install it on such lousy motherboard that will make your computer to run like an old Pentium 4 2.4 GHz? In other words, you will buy a new computer and will get a performance level worse than the performance level provided by computers with on-board video from four years ago.
