1) Message boards : News : OpenCL for Nvidia available for testing (Message 44638) Posted 3 Dec 2010 by One World, One Dream Post: I have tested the new OpenCL app with a Geforce GT 420m notebook GPU. When I used Crunch3er's optimized app in the past, my work units took either 49 or 73 minutes to complete. With the new OpenCL app, work units need either 51 or 75 minutes to complete. I do not know why the new app is actually a bit slower, maybe it is because I was surfing on the web and displaying some images while running the work units? (though simple tasks like this never seemed to affect the work units of the old app by Crunch3er) Furthermore, there is a significant difference in system responsiveness and a slight difference in GPU temperature between the two apps. While Crunch3er's app did not cause any negative effects regarding system responsiveness, the new OpenCL app causes the system to react very sluggishly, so that comfortably writing something or surfing the web is not possible anymore. Lastly, GPU temperature with the OpenCL app is about 3 degrees celsius higher than with Crunch3er's app. That is why I have now switched back to the old app for the time being. I hope my information gathered about the performance of the new app is helpful.
