9 -Video Transcoding | CPU-Bound 3D Rendering | Data compression

Multi-threaded Video Transcoding VC-1 to WMV9

Every now and then you see an anomaly in benchmarks, this was the one for this mainboard. We ran is multiple times, reset the system, checked parameters & settings yet everything was setup equally to the 780G mainboard. The Transcoding results were off the chart, in favor for the GF8200A and new 790 GX mainboardss. Here we clearly see more advantage for the Phenom with it's 4 cores on the 790GX chipsets.

CPU-Bound 3D Rendering

We recently stumbled onto this great little tool called Kribibench. It is a 3D rendering benchmark produced by the people at Adept Development. Kribibench is an SSE aware software renderer where a 3D model is rendered and animated by the host CPU and the average frame rate is reported. Now the great thing is, it therefore bypasses the GPU .. so everything is in direct relation towards your memory and CPU.

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 "City" model that is comprised of over 107 billion polygons.

This is the first time we are implementing this multi-threaded tool. You can see the multiple cores kick in very well. It's still astonishing to see that a higher clocked Core 2 Duo processor can keep up extremely well. On top the mainbaord overclocked to 3080 MHz on all four logical CPU cores.

Data compression

A quick data compression test measured in MB/sec, this test only used two threads though. It utilizes ZLIB and then pushes it over two threads, which will bring the results a bit closer together. The Phenoms based PCs surely love it. The 780G platform is again slightly faster, but the overall difference is so small.

Let's try some games.
