GCC 4.6 faster than previous GCC, faster than LLVM

Whilst all benchmarks are a bit synthetic, this one is better than most: http://www.phoronix.com/scan.php?pag...gonegg28&num=1 Whilst it doesn't show Intel or other compilers - only GCC, CLang and LLVM variants - and sadly it doesn't do before-and-after profile-guided-generation, it does show hard results with some eye-openers. GCC 4.6 is faster than others in some stuff, whereas for ray-tracing the LLVM wiped the floor with the opposition. And the the 7-zip part showed how the i7 rocked (I was surprised how well the Opterton kept up with the i7 on other benchmarks). So file this under the 'interesting' rather than 'definitive' category, but a good read none-the-less.

Thanks again, read the 1st article the other day and GCC 4.6 is sure looking promising.
