Mandel FPU test
This 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.
FPU Mandel test again is HyperThreading, multi-processor (SMP) and multi-core (CMP) aware. If we focus on the QX9650 & QX9770 we notice a 6% difference. If we measure the floating point performance of the QX 9770 processor between Intel's X38 chipset and the 780i Chipset from NVIDIA the difference is again NIL.
File Encryption & Decompression
Encrypting is becoming more and more popular task with file sharing. Many companies already have a policy where all emails for instance must be encrypted. This test involves encrypting of different kind of files.
File decompression are very popular tasks in todays PC usage, especially files transferred over a network are almost without exception always compressed. These tests use the open source Zlib data compression library.
The amount of operations processed during the 20 second run time is calculated for both tests and the metrics is Megabytes processed per second.
Again the differential between the X38 and the 780i again close to NIL, in real-world situations not noticeable.
WMV Compression & File Decryption
WMV Video Compression - With digital video cameras increasingly gaining popularity, video conversion and editing is becoming a very popular task in home PC usage. This video compression tests measures two different types of video file conversion. In the WMV Video Compression test, a Windows Media format video file is encoded. This test uses the Windows Media Encoder 9. The video source data file used for the encoding is approx. 1.8 MB sized mpg file with a resolution of 320*240. Video compression is done through Windows Media Encoder to same resolution WMV format with video bitrate of 1000kbps.
File decryption - Many companies already have a policy where all emails for instance must be encrypted. The files used for decrypting include 2MB executable, 2MB document, 1.1MB picture and a 1.7MB audio file. The files are en/decrypted in 8 byte padded blocks and the encryption key size is 56 bytes.
Once we compress a WMV file we again see no difference, as well on File Decryption.
