    Difference between single score and multi score benchmarks on geekbench 3?

    Difference between 32 bits and 64 bits scores?

    32 bit scores can only take into account of memory performance with a maximum of 4GB RAM.

    The difference between single and multi core is self-explanatory. Single core tests just use one core to test, while multi core tests use all cores available to test.

    To add to this, not all programs are designed to use multi-core, so single-core benchmarks are also important.

    What is probably more relevant is that the code generated in the 32 bit mode is often less efficient (hence slower) because it does not have the access to extended registers and new instructions.

    Then again, if Geekbench would properly utilise the modern CPU's features, it would show rather different results. I would certainly take the geekbench scores with a (huge) grain of salt.

    What is a good CPU benchmark application utilizing modern CPU features for multiple platforms then?

    I am not aware of one, unfortunately.
