9 - Memory | Floating Point | Transcoding performance

Memory test

Lavasys Everest has an excellent tool to measure memory bandwidth. Inside the PC is G.Skill memory and as you can see, it's extremely fast in its write operations.

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.

the FPU Mandel test again is HyperThreaded, multi-processor (SMP) and multi-core aware. Here's where faster clocked Quad core processors always really kick in as you can see.

Multi-threaded Video Transcoding VC-1 to WMV9

Transcoding is a very popular thing to do on PCs. You take a movie and transcode it from format A to B. Example in this test we transcode a high-definition VC1 movie towards a WMV9 format.
