In university, the furthest down we got was C++ and we didn’t spend that much time there, so everything under that has always felt a little like black magic to me. To overcome …https://www.learnopengles.com/a-performance-comparison-redux-java-c-and-renderscript-on-the-nexus-5/Thu, 10 Jul 2014 15:04:44 +0000https://www.learnopengles.com/a-performance-comparison-redux-java-c-and-renderscript-on-the-nexus-5/In my previous post on this topic, A performance comparison between Java and C on the Nexus 5, I compared the performance of an audio low-pass filter in Java and C. The results were clear: The C version outperformed, and by a significant amount.
