S3 Graphics S3FotoPro Quick Review


 S3FotoPro is a GPGPU (General Purpose GPU) acccelerated utility for image processing. S3FotoPro requires Windows XP SP2/3 or Vista SP1 and a Chrome-based S3 graphics card. Geeks3D has such a graphics card (a S3 Chrome 430 GT) so let’s play a little bit with this software.

SIGGRAPH 2008 Presentations: Programming with CUDA

NVIDIA has released two SIGGRAPH 2008 presentations about CUDA. The first one talks about image processing and video algorithms with CUDA and shows some CUDA applications such as image filtering (sobel filter with code sample). This presentation talks also about NVCUVID, the video extension for CUDA. NVCUVID is similar to DXVA API, but is platform OS independent.


The second presentation is more general about CUDA programming and shows how to create high performance code to run on the millions of CUDA-capable GPUs already in use.

GPU benchmark tool for image processing

Here is a small benchmark that try to compare several optimized Intel OpenCV library functions with their GPU analogs, written using OpenGL and GLSL shader language.

More information HERE.

Because I can’t resist, here is my score (Core 2 Duo 6600 default clocks, Radeon HD 3870 Catalyst8.5, WinXP 32-bit) with Resolution multiplier set to 4:

------------ CPU  | GPU
step1:       75.3   21.5
step2:       35.8   22.5
step3:       05.7   00.7
Total Time: 116.9  345.3
