It's neither complex, nor is there an unclear answer. "The performance of a single-core Atom is about half that of a Pentium M of the same clock rate. For example, the Atom N270 (1.60 GHz) found in many netbooks such as the Eee PC can deliver around 3300 MIPS and 2.1 GFLOPS in standard benchmarks,[34] compared to 7400 MIPS and 3.9 GFLOPS for the similarly clocked (1.73 GHz) Pentium M 740." - https://en.wikipedia.org/wiki/Intel_Atom#Performance http://www.intel.com/content/www/us/en/processors/core/core-i7-processor.html https://en.wikipedia.org/wiki/Intel_Core#Core_i7_3 "Core i7 Sandy-Bridge, 3,4 GHz, 4 Kerne 102,5 GFLOPS" - https://de.wikipedia.org/wiki/Floating_Point_Operations_Per_Second#Rechenleistung_von_Computersystemen The German "102,5 GFLOPS" are English "102.5 GFLOPS" If you compare 32 bit Atoms, then better compare them with 64 bit Atoms and not with completely unrelated CPUs, that are way beyond the Atom's processing power.
