GCC 4.8 Snapshot Intel Ivy Bridge Benchmarking of a GCC 4.8 snapshot from 2012-06-17 on an Intel Core i7 3770K Ivy Bridge system at Phoronix.com. Benchmarking for a future article. GCC 4.8 snapshot was compared to the latest of the GCC 4.6 and GCC 4.7 compilers when being built with the same compiler options. CFLAGS/CXXFLAGS of -O3 and -march=native were set each time prior to test profile installation.
