With the Bullet Physics tests, the race was close.

Clang was slightly slower with the LAME MP3 encoding test.

Clang trailed GCC with HINT.

The rest of the race was fairly close between GCC and Clang.

Well, those are the latest numbers to share of this GCC and Clang C/C++ compiler benchmarking for those interested in how they compare on Linux x86_64. Stay tuned for some ARM Linux tests and other compiler optimization tests forthcoming on Phoronix.
