GCC 4.9 vs. GCC 5.1 vs. GCC 6.0 SVN Compiler Benchmarks

Here's some new GCC compiler benchmarks on Linux x86_64 for your viewing pleasure this weekend.

The tests I did on an Intel Xeon box were freshly built versions of GCC 4.9.2, GCC 5.1.0, and the latest SVN snapshot of the GCC 6.0 compiler that's under development for release in 2016. The three compilers were built the same way and then they went on to build our many open-source Linux CPU benchmarks via the Phoronix Test Suite automated benchmarking software.

Some of the results are interesting and show change in GCC's performance on this Haswell-based system over the past two years. However, not in all of the tests was there measurable change.

Head on over to this OpenBenchmarking.org result file to take a look at the latest GCC compiler performance comparison. Also be sure to visit LinuxBenchmarking.com for benchmarks of GCC and LLVM Clang done on many systems on a daily basis! Feel free to run your own compiler benchmarks with our industry-leading Phoronix Test Suite benchmarking software.
