Overclocking on the Xabre reference card was surprisingly impressive. Being clocked at a default speed of 250MHz core and 250MHz memory clock we managed to run a maximum speed of 308MHz core and 295MHz (590MHz DDR) memory clock through the latest version of PowerStrip. We found this rather surprising since this is a reference card which we don't usually see good overclocking results from.
In the past we have seen that SiS 3D chipsets have been something that should have been placed in a wood heater rather than a PC, to be perfectly honest. The new strategy from the R&D team at SiS has turned a few heads, not only with the Xabre but with their new AMD and P4 chipset offerings...That's what first made me think "Have they done it?"...The answer is Yes.
Hardware wise the Xabre exceeds the limits normally set for a value based 3D accelerator, and while being able to keep within relatively close proximity of the Geforce MX460 (its main competitor, SiS tells us), with these early drivers competing against nVidia's mature drivers, is quite impressive.
SiS needs to now divert a bit more effort into researching their drivers, as they still need some tweaking and patches for games to allow the pixel shader technology to be fully optimized, as well as ironing the bugs out that we saw and others have seen.
Summing it up SiS have done an excellent job to produce a very well rounded video card that could be the next biggest vale card that the Geforce 2 MX originally was, only time will tell
