GCC 4.9 vs. LLVM Clang 3.5 On Intel's Haswell-E Platform Under Linux
With my Intel Core i7 5960X Haswell-E Linux review out there, one of the quick to be requested extra tests is benchmarking the i7-5960X 16-thread processor with LLVM/Clang against GCC. Here's some initial data comparing the compilers for this $1000+ processor.
From the Core i7 5960X system with Gigabyte X99-UD4-CF motherboard, 16GB DDR4 memory, and 128GB SSD, Ubuntu 14.10 was running on the system with its stock Linux 3.16 kernel. For this quick, one-page testing of the i7-5960X compilers I used the packaged GCC 4.9.1 amnd LLVM Clang 3.5.0 compilers found within the Ubuntu 14.10 package archive.
