10. Benchmarks

Our results show how the iPAQ rx3715 with Samsung application processor beats the performance of an XScale-powered model like the Axim X30 from Dell. We also took a look at battery life.

CPU Performance With WmmX

With Sandra Pro we deliberately chose an application containing wireless MMX-optimized program code. Why? Just to show that this application also runs on a system like the iPAQ rx3715, which does not "understand" MMX code.

MMX commands are not used with the Arithmetic Benchmark CPU. Samsung's S3C2440 microcontroller is easily on par with Intel's PXA26X and PXA27X series in this test category and its nearly identical core clock speed.

Everything looks different as soon as typical integer operations for multimedia applications come into play. In this situation both of the CPUs from the Intel camp, the new 312MHz PXA270 and the somewhat older 400MHz PXA263, outdo their Samsung rival.

With floating point operations Samsung's protégé is able to defy Intel's supremacy.
