GCC 4.5 Through 4.8 For AMD's Bulldozer
Written by Michael Larabel in Compiler on 28 September 2012 at 03:09 AM EDT. 1 Comment
While the new AMD Trinity APUs are what's exciting and being benchmarked at the moment, here are some updated compiler tests from earlier this month on an AMD FX-8150 Bulldozer system.

To complement the recent GCC 4.7 AMD Bulldozer Compiler Tuning results, here are results when benchmarking GCC 4.5.4, 4.6.3, 4.7.1, and 4.8.0 20120909 (development snapshot) from the FX-8150 system while maintaining the same compiler flags. The tested GCC releases were also built the same throughout from this system running Ubuntu 12.10 x86_64.

All benchmarking was handled by the Phoronix Test Suite and the results in full are hosted on OpenBenchmarking.org.

While succeeding GNU Compiler Collection releases haven't always improved the performance of the resulting binaries, in a majority of the cases for these common open-source computational benchmarks it has improved with time. Only in a select number of cases has the GCC performance regressed. Find the results in full on OpenBenchmarking.org.
