We have run some tests to check the vector performance of Pentium with SSE/SSE2 and vectorizing compilers. The Portland and the Intel compilers has been used to generate vector code. Two cpus, Pentium III and 4, at 800 MHz and 1.5 GHz has been used. We conclude that for overall performance of the vector benchmark the vector code is performing better than scalar code. The speedup with the vector benchmark is significant, but less than expected. Results are published at http://computational-battery.org/Maskinvare/ "Vector performance for Pentiums with different compilers ". The benchmark is a modified version of : http://www.netlib.org/benchmark/vectors and vectord -- Ole W. Saastad Scali A/S.
