Grand Central Dispatch and Open CL Bring Significant Performance Improvements for Optimized Applications
Christophe Ducommun who keeps optimizing Snow Leopard for his application MovieGate just sent us results to illustrate how Snow Leopard can improve performance when one can make use of Grand Central and Open CL. Tests below have been performed with a Mac Pro 2007 (Quad Core 2.66 GHz with a GeForce 8800 GT).The results include an approximately 50% increase in video encoding speed when compared to Leopard, while also reducing the CPU load during video decoding by passing some of the work to the graphics processing unit.
150 frame/s for encoding in MPEG-2
70% CPU load for decoding
130% CPU load for MPEG-2 encoding (ffmpeg)
104 frame/s for encoding in MPEG-2
165% CPU load for decoding
100% CPU load for MPEG-2 encoding (ffmpeg)
