Gigabyte K8S760M (SiS760)
Review
(6)
Benchmarking SiS 760 chipset has something different from the previous integrated chipset. As we know the older SiS 740/741/650 only share the on board memory for video. SiS 760 chipset, which the board is based on allows the system to tap the memory either from the on board DDR ram and/or integrated video chips on the mainboard itself. We call this two technology UMA (shared) and LFB (local frame buffer - the chips soldered on the mainbaord-see gallery). You can have 64M UMA, 64 LFB or 64M of LFB + 64M UMA giving you 128M. In this section, we check out various benchmarks using the integrated video. The benchmarks run are CCWS2002, Quake 3, 3Dmark2001 and 3DMark2003 and observe the impact with local frame buffer. On Business Winstone 2002, the difference is not as apparent as CCWs2002 do not require too much of 3D but more on 2D. We see that the results are pretty close with a minor difference of 2 points. It also seems that using the on board video with LFB scored better than using an external VGA card or using UMA mode (integrated).
As for 3Dmark2001SE, the scores doubled when we used the LFB. In fact, with another 64M UMA, it doesn't seem to boost the results but scored a drop of 3 points. Well, it seems that LFB itself would be good enough.
Again, we see that if we use LFB or LFB+UMA, the score is the same. The fact is that with LFB, the performance is much better than using UMA.
In Quake 3, we see the score almost doubled with LFB. Again LFB+UMA doesn't seem to boost it further.
