AMD Bulldozer With GCC, Open64, LLVM/Clang Compilers

AMD's Open64 compiler had a setback in the Apache web-server performance compared to the rest.

The MAFFT performance was not too interesting except for LLVM/Clang lagging behind the other compilers.

AMD's Open64 compiler tends to noticeably increase the performance overall for many applications/benchmarks running on their FX-8150 Bulldozer, but it was not the clear winner. Depending upon the workload, GCC and LLVM/Clang can still deliver a competitive advantage. Next up is a look at these compilers with various compiler-tuning options for the first-generation AMD Bulldozer processors.
