Everest has an excellent tool to measure memory bandwidth, surprisingly the GA-X48-DQ6 is performing pretty much on par. On all platforms the memory was locked at the same frequency, voltage and timings.

Mandel FPU test

The Mandel FPU benchmark measures double precision (also known as 64-bit) floating-point performance through the computation of several frames of the popular "Mandelbrot" fractal. The code behind this benchmark method is written in Assembly, and it is extremely optimized for every popular AMD and Intel processor core variants by utilizing the appropriate x86 or SSE2 instruction set extension.

Now if you come from the Commodore 64 / Amiga era like me, you can probably remember rendering Mandelbrot graphics, and it took a full day to complete an image. Amazing where we are right now as the same set of calculations can be done in seconds & even real-time.

FPU Mandel test again is HyperThreading, multi-processor (SMP) and multi-core aware. Here's where the Quad core processors really kick in. The Intel X48 based GA-X48-DQ6 is showing leading performance here.

Multi-threaded Video Transcoding VC-1 to WMV9

We ran is multiple times, reset the system, checked parameters & settings yet the GA-X48-DQ6 was just faster than the 680i. No clue as to why. Then again e have seen more small anomalies with this benchmark. We might ditch it in the near future if results remain inconsistent.
