In “ARM Cortex-A8 vs. Intel Atom: Architectural and Benchmark Comparisons,” Katie Roberts-Hoffman and Pawankumar Hegde at the University of Texas at Dallas look at the performance and power requirements of mobile internet devices.

They compared a Texas Instruments OMAP3530-based Cortex-A8 used in a variety of smartphone and wireless tabled designs to Intel’s X86-based Atom N330 for clock rates, power, price, and die size. Their results: the Atom has better raw performance while the Cortex-A8 has significantly greater power efficiency.
