Phoronix: LLVM 2.9 Clang Performance On Intel's Sandy Bridge

Earlier this month benchmarks were published on Phoronix showing the GCC 4.6 compiler performance with AVX support under Intel's new Sandy Bridge processors that are the first to provide Advanced Vector Extensions support. The Core i5 2500K CPU performance is already great under Linux, but once more Linux software supports taking advantage of this latest cross-vendor instruction set, there will be even more speed-ups. While the Low-Level Virtual Machine does not yet have full support for taking advantage of the Advanced Vector Extensions support, in this article we are looking at how the latest development code for LLVM 2.9 and the Clang compiler are performing on Intel's Sandy Bridge in relation to GCC.
