Benchmarks - RealStorm

This tool does realtime raytracing, a very computational intensive application that does software rendering. Thus, it requires high speed processors to do it. The author said "Of course 3D-Accelerators are getting faster too and evolve feature-wise, but beyond a certain level of detail, a polygon has to be smaller than a pixel on the screen. In this case, there is absolutely no reason to use polygon routines. So we decided to use platonic solids combined with boolean algebra and raytracing.

We chose this because it uses very complex mathematic algorithms which takes almost 100% of calculations are done by the main cpu.

There are 5 real time rendering scenes, RCMP, HouseV, HouseR, HouseG and White. The 3 boards with the same CPU and RAM goes through the same benchmark and we found that all three boards gets very close in scores except in the HouseR rendering scene. In fact, for all the scenes, the frame rate in real time hardly exceeds 12fps. That is how CPU intensive this thing can be.

From the chart, we can see that both DDR or DDR2 takes almost the same amount of time to complete the ray tracing.

As this application is not GPU bound, we can safely compare the results to our previous benchmarks of the 965p boards.

For White, we get 1172, for the PX1 which is a dual channel architecture chipset, it scored 1206. For HouseG, P4M800Pro scored 460 whereas PX1 did 473.

In HouseR, we get 5392 and PX1 scored 6864. In HouseV, we get 2540, PX1 scored 2904. In RCMP, we get 2370 while PX1 gets 2633.

From the scoreline, we can gauge the performance difference between a single channel and dual channel chipset. Here is a breakdown :
