Intel Core 2 Extreme QX6850
KribiBench v1.1
Next we ran Kribibench v1.1, a 3D rendering benchmark produced by Adept Development. Kribibench is an SSE aware software renderer in which a 3D model is rendered and animated by the host CPU rather than the GPU, then the average frame rate is reported.

We used two of the included models with this benchmark: a "Sponge Explode" model consisting of over 19.2 million polygons and the test suite's "Ultra" model that is comprised of over 16 billion polys.
In both the medium complexity polygon count and high complexity/high polygon count tests, the QX6850 showed only a minor gain versus the QX6800. Clearly the quad-core CPUs took a huge lead in this test at nearly 2X the fastest dual-core score we recorded. However, the QX6850 offered a less than 1% performance advantage in this test versus the QX6800. The scores here are indicative of the 70MHz clock speed advantage the 3GHz QX6850 has over the 2.93GHz QX6800. Front Side Bus speed doesn't even enter into the equation.
