Ubuntu 12.04 x86_64 64-bit vs. 32-bit performance on Intel Core i7 notebook. 32-bit Ubuntu Linux benchmarking was with the 32-bit and 32-bit PAE (Physical Address Extensions) kernels. Testing of 8 February Precise Pangolin development snapshot, all other software versions/configurations remained the same besides swapping the kernels. Testing for a future article on Phoronix.com by Michael Larabel.

The Himeno benchmark is a linear solver of pressure Poisson using a point-Jacobi method. Learn more via the OpenBenchmarking.org test page.
This test searches through the Pfam database of profile hidden markov models. The search finds the domain structure of Drosophila Sevenless protein. Learn more via the OpenBenchmarking.org test page.
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.
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.
This is a test of OpenArena, a popular open-source first-person shooter. This game is based upon ioquake3, which in turn uses the GPL version of id Software's Quake 3 engine. Learn more via the OpenBenchmarking.org test page.
