When it comes to FFmpeg and other multimedia applications that rely upon highly-tuned Assembly, there isn't much difference between GCC and Clang.

With the Hierarchical Integration test, Clang 3.5 is trailing a ways behind GCC.

The Apache web-server performance was close between GCC and Clang of the tested versions.

There you have it for a brief look at GCC 4.8/4.9 against LLVM Clang 3.5 SVN. More extensive benchmarks will come in the following days in looking at GCC 4.9, which should be officially released next week, while LLVM Clang 3.5 will likely be released around June of this year. See our many other GCC 4.9 articles for those interested in next week's release of the Free Software Foundation compiler.
