Intel Core i3/i5/i7 Ubuntu Linux Performance Update

Earlier today on Phoronix I delivered benchmarks showing Intel's Haswell graphics falling behind Ivy Bridge on Linux, something not seen previously and certainly not what's expected. Curious to see whether this likely Intel Haswell Linux performance regression was limited to just the HD Graphics or the processor performance overall, here's the complementary set of Sandy Bridge, Ivy Bridge, and Haswell benchmarks. These tests span the Core i3/i5/i7 series when using the latest Ubuntu 14.04 packages and the Linux 3.13 kernel with these benchmarks focusing upon the processor performance.

For this latest Intel CPU performance update are the results from the Core i3 2120, Core i5 2500K, Core i5 3470, Core i7 3770K, Core i3 4130, and Core i7 4770K. All processors were with their stock settings and all the components were maintained the same where possible (sans switching out the motherboard between Haswell and Sandy/Ivy Bridge).

The software stack included Ubuntu 14.04 in its daily ISO state while using the mainline Linux 3.13 development kernel, GCC 4.8.2 compiler, and the EXT4 file-system. All benchmarks were facilitated in a fully automated and reproducible fashion using the open-source Phoronix Test Suite software; simply run phoronix-test-suite benchmark 1401120-PL-INTELCORE39 on your own system to see how these Intel Core i3/i5/i7 CPUs on the latest Ubuntu Linux software compare to your own system.
