• Memory bandwidth using transfers to/from main registers.
• Memory bandwidth using transfers to/from vector registers.
• Integer math operations.
• Single-precision floating point math operations.
• Double-precision floating point math operations.
• Prime number generation.
On current 64-bit devices iBenchmark currently provides fewer tests:
• Memory bandwidth using transfers to/from main registers.
• Single-precision floating point math operations.
• Prime number generation.
Thus, iBenchmark provides a technical assessment of individual aspects of performance, not just one number.
For reliability, all of iBenchmark's core routines are written in assembly language. This ensures that it is the same measurements being performed across different iOS devices, and over time, removing variability due to changes in the compiler, and eliminating bogus results due to compiler optimization.
