| SSBENCH Integer Speed Index (SIint) for Unix/Linux |
Back to Stefan's Benchmark page
The computers below are listed in performance order.
Note, the results are for non-parallel compiling only. I.e. the benchmark
is run on a single CPU core also on multi core machines.
Note, CPUs added at the latest updates are marked with blue "Nr" below.

The CPU-time is calculated as the Geometric Mean (GM) of 8 programs.
The Speed Index (SI) is calculated as 1000.0/GM. The Speed Index is
normally NOT proportional to the SPEC benchmark result, but it can
be used in the same way to compare different computers.
See also the commonly used SPEC benchmark.
