We are considering using an upcoming version of the Intel Atom SoC, I believe the current code name is tunnel creek. Anyway, my boss asked me the other day how we could expect the Intel Atom to perform in comparison to a comparable ARM9(same amount of cache, clock, bus to RAM, amount of RAM). I was a bit stumped, another engineer said he would expect the Atom to blow away a comparable ARM9, he said he would expect it to be two to three times faster. I'm not familiar with the architecture of the Atom, or what tricks Intel has come up with recently. It's been about five years since my computer architecture courses in school. Can anyone done any benchmarks, or could anyone comment from a theoretical point of view?
