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.
