From a high-end processor like MIPS P5600 to a mid-range CPU such as MIPS InterAptive CPU and a microcontroller CPU like MIPS M51, Imagination boasts that each MIPS core consistently scores higher CoreMark/MHz across the board, when each CPU is compared to its competitors' equivalent offerings. (These are "apple-to-apple" comparisons, according to Imagination, as it compares each at the same process node, the same L1/L2 cache, etc.)
As you can see in the bar graph above, the difference in performance is about 10 percent at the same frequency between MIPS's P5600 vs. ARM's apps processor CPU. Where MIPS sets itself apart further is in its performance in power consumption (CoreMark/mW) and area (CoreMark/mm2), according to Imagination.
