GCC 4.9 Shows Little Change For AMD's Kaveri

Our latest Linux benchmarks of AMD's new "Kaveri" APU with Steamroller processor cores is comparing the GCC 4.8.2 compiler performance to the very latest GCC 4.9 compiler snapshot to see how the performance is fairing for this next Free Software Foundation compiler release due out within the next few months.

If you're not yet familiar with the features of GCC 4.9, check out our GCC 4.9 feature overview and dozens of other compilers about this major update to the GNU Compiler Collection that will likely come either late this quarter or early next quarter. There's new CPU support, support for new C and C++ language features, initial support for OpenMP 4.0, Intel Cilk Plus multi-threading support, Address Sanitizer improvements, and a whole lot more.

The benchmarks in this article are of GCC 4.8.2 and GCC 4.9.0 20140126 being built fresh from source on an AMD A10-7850K "Kaveri" system with Gigabyte F2A88XM-D3H motherboard and running an Ubuntu 14.04 development operating system with Linux 3.13 kernel.

All benchmarking was handled via the Phoronix Test Suite.
