GCC 4.9 vs. LLVM Clang 3.5 Linux Compiler Benchmarks
Some early compiler benchmarks of LLVM Clang 3.5 SVN against GCC 4.9.0 RC1 on Ubuntu 14.04 LTS with the Linux 3.13 kernel and using an Intel Core i7 4770K Haswell system. Benchmarks by Michael Larabel for a future article on Phoronix.com.

Hierarchical INTegration
This test runs the U.S. Department of Energy's Ames Laboratory Hierarchical INTegration (HINT) benchmark. Learn more via the OpenBenchmarking.org test page.
FLAC Audio Encoding
LAME MP3 Encoding
LAME is an MP3 encoder licensed under the LGPL. This test measures the time required to encode a WAV file to MP3 format. Learn more via the OpenBenchmarking.org test page.
Himeno Benchmark
The Himeno benchmark is a linear solver of pressure Poisson using a point-Jacobi method. Learn more via the OpenBenchmarking.org test page.
Timed ImageMagick Compilation
Timed Apache Compilation
Timed PHP Compilation
GraphicsMagick
This is a test of GraphicsMagick with its OpenMP implementation that performs various imaging tests to stress the system's CPU. Learn more via the OpenBenchmarking.org test page.
C-Ray
This is a test of C-Ray, a simple raytracer designed to test the floating-point CPU performance. This test is multi-threaded (16 threads per core), will shoot 8 rays per pixel for anti-aliasing, and will generate a 1600 x 1200 image. Learn more via the OpenBenchmarking.org test page.
FFmpeg
Smallpt
Smallpt is a C++ global illumination renderer written in less than 100 lines of code. Global illumination is done via unbiased Monte Carlo path tracing and there is multi-threading support via the OpenMP library. Learn more via the OpenBenchmarking.org test page.
Apache Benchmark
This is a test of ab, which is the Apache benchmark program. This test profile measures how many requests per second a given system can sustain when carrying out 1,000,000 requests with 100 requests being carried out concurrently. Learn more via the OpenBenchmarking.org test page.
