IPP on Pentium M

IPP on Pentium M

The IPP webpage and documentation don't really mention Pentium M.
I am working on a project where we are considering using Pentium M (Dothan) 755 (2 GHz) processors instead of Pentium 4 3 GHz processors to reduce power consumption.
How does the performance of IPP compare on the two architectures?

For more complete information about compiler optimizations, see our Optimization Notice.

Intel IPP also supports Intel Pentium M processors, it will detect such a processor as Intel Pentium 4 processors as we do not have specific optimization for Pentium M processor.

For compare the performance between Pentium M (Dothan) 755 (2 GHz) processors and Pentium 4 3.0 GHz, I would recommend you to run the Intel IPP performance tool on those two target systems. This tool is located in the directory..IPP41ia32_itanium oolsperfsys,you can run each executable filebased onthe domains tomeasure each IPP function on various Intel-based systems.Please checkthe readme file in this directory for details.

Hope it helps.

That's interesting. I've read a number of things suggesting the Pentium M core is more similiar to the Pentium III architecture than the Pentium 4.
Also, the stuff I've read about the Intel compiler says that the Pentium M has some limitations with decoding SSE instructions and therefore prefers a different mix of instructions than the Pentium 4.


you can find more details about Intel Pentium M processors family and optimization technology for them here
