Phoronix have been very busy lately, getting their heads around the functionality of Ivy Bridge on Linux and as these processor are much more compatible than their predecessors it has resulted in a lot of testing.  The majority of the testing focused on the performance of GCC, LLVM/Clang, DragonEgg, PathScale EKOPath, and Open64 on an i7-3770K using a wide variety of programs and benchmarks.  Their initial findings favoured GCC over all other compilers as in general it took top spot, with LLVM having issues with some of their tests.  They then started to play around with the instruction sets the processor was allowed to use, by disabling some of the new features they could emulate how the Ivy Bridge processor would perform if it was from a previous generation of chips, good to judge the improvement of raw processing power.  They finished up by testing its virtualization performance, with BareMetal, the Kernel-based Virtual Machine virtualization and Oracle VM VirtualBox.  You can see how they compared right here.

"From an Intel Core i7 3770K "Ivy Bridge" system here is an 11-way compiler comparison to look at the performance of these popular code compilers on the latest-generation Intel hardware. Among the compilers being compared on Intel's Ivy Bridge platform are multiple releases of GCC, LLVM/Clang, DragonEgg, PathScale EKOPath, and Open64."
