GCC 4.8.2 vs. GCC 4.9.0 Benchmarks On Intel's Core i7 Haswell
GCC 4.9 is gearing up for a release likely in April so I spent part of Sunday morning running some fresh benchmarks of GCC 4.8.2. vs. GCC 4.9.0 20140323 on an Ubuntu 14.04 LTS system running Linux 3.13 x86_64. Both of the GNU Compiler Collections were built from source in the same configuration. The CFLAGS/CXXFLAGS remained the same during the testing.
All of the system details and results from this weekend GCC 4.9 compiler benchmarking can be found on OpenBenchmarking.org via 1403300-PL-GCC49LATE47. Testing happened from a Core i7 4770K "Haswell" system with the latest version of the Phoronix Test Suite.
