Intel Atom D525 Compiler Testing
Intel Atom D525 testing with GCC 4.7 and LLVM/Clang 3.0 from the Ubuntu Quantal repository. Benchmarking by Michael Larabel for a future article on Phoronix.com just looking at GCC vs. Clang on low-end low-power x86 hardware.

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.
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.
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.
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.
