While still playing the CUDA card, Nvidia continues to show OpenCL more love than AMD, and the latest move to prove that is the Green Goblin's release of a OpenCL performance profiler for the GPU. Set to provide developers precious info regarding performance bottlenecks in their OpenCL software, Nvidia's Visual Profiler includes the following key features:

- Profiling of actual hardware signals, kernel efficiency, and instruction issue rate
- Timing of memory copies between system memory and GPU dedicated memory
- Customizable graphs to help developers focus in on problem areas
- Basic auto-analysis to reveal warp serialization problems
- Easy import/export to CSV for custom analysis

According to the Santa Clara-based Tegra maker, the OpenCL Visual Profiler is now available to all Nvidia GPU Computing Registered developers, and is set to be added to the next version of the CUDA Toolkit.
