LLVM Clang 3.4 Is Running Very Well On AMD's High-End APU

After earlier this week running GCC 4.8.2 vs. GCC 4.9 development snapshot benchmarks on the AMD A10-7850K Kaveri APU, up for testing today are new compiler tests from this new high-end APU comparing GCC 4.9 in its current development form to LLVM Clang 3.4. This GCC 4.9 vs. LLVM Clang 3.4 compiler performance comparison is more competitive than some of the past compiler comparisons and does hold a few surprises.

Intel Haswell Might Have Regressed Hard On Linux

For your viewing pleasure this weekend are some extra benchmarks of various Intel Sandy Bridge, Ivy Bridge, and Haswell HD Graphics when using an Ubuntu 14.04 Linux development snapshot with the Linux 3.13 kernel and Mesa 10.0.1. The processors tested included the Core i3 2120, Core i5 2500K, Core i5 3470, Core i7 3770K, Core i3 4130, and Core i7 4770K. These tests appear to represent a huge drawback in performance for Intel Haswell on Linux compared to earlier results.

Linux 3.13 Kernel HDD File-System Benchmarks

The Christmas benchmarks we have to share on Phoronix today are of testing the XFS, Btrfs, and EXT4 file-systems on the Linux 3.13 development kernel compared to Linux 3.12 from a high-performance hard drive. Earlier this month results were shared on Phoronix that indicated file-systems on a solid-state drive slowing down with this new Linux kernel, but is that also the case for HDDs?

GCC 4.9 Compiler Benchmarks On A Dual-Core Haswell

While extensive benchmarks of the GCC 4.9 development compiler are currently ongoing, here's a preview of the performance that the GNU Compiler Collection is set to offer in 2014 with its next major update. For this article an Intel Pentium "Haswell" dual-core processor was tested on a GCC 4.9 development snapshot and compared to GCC 4.8.2 and GCC 4.7.3 in a wide variety of C/C++ workloads. New LLVM Clang 3.4 benchmarks are also happening.
