SiS672FX - Budget for Budget's Sake

Results - SPECviewperf 9.0

There is really nothing that needs to be said about these SPECviewperf 9.0 scores either way since none of the IGP cores and their drivers are optimized for OpenGL performance. Even so, we can see the direct effects of IGP architecture, drivers and memory subsystem on overall performance in these tests. Here, the Intel G965 was actually slower than the 945G probably because of its CAS 5 timing, compared to CAS 4 for the 945G. However the real crux of the outcome is due to the different IGP architecture of the GMA X3000 and that of GMA X950 whereby Intel has yet to capitalize on the GMA X3000's hardware potential with good drivers - something which they don't seem to be very good at this point of time, more so because it's an OpenGL API. This is not the first time we've encountered this, thus the scores are quite normal and expected.

That aside, again we noted that the G965 did not really lose much performance between single and dual channel modes. The SiS672FX on the other hand, can be considered quite dismal, in both the graphics and memory subsystem performance.
