I already published some CoreMark results for ARM processors found in high end smartphones (e.g. iPhone 3G/3GS and iPhone 4) as well as netbooks.
After the Apple iPad revolution a number of tablet clones is invading the market and there is a lot of confusion with the used processors. Very ofter you only hear something like 600MHz or 1GHz processor, this can be misleading since there is a huge difference between different cores even though they are running at the same clock!
ARM Cortex A8 and A9 are way more powerful than ARM9 and ARM11 cores!
Below CoreMark benchmark results for ARM9, ARM11, Cortex A8, Cortex A9 and Intel Atom processors.
I also created a summary table reporting which ARM core you find in different SoCs.
