A desktop CPU probably has about an order of magnitude more power per cycle than a mobile chip.
They have bigger caches (less time spent waiting for memory), more logic units, deeper pipelines, and can handle far more 'in-flight' instructions.
That said, the smart phones of today probably do have more power than desktop computers of about 10 years ago.
edit: now that I think about it, a order of magnitude is probably generous, but I would still guess that it's at least a factor > 2.
- ypcx 15y agoI don't have time to get better data, i.e. I couldn't find any MFLOPS data for a mobile CPU (not GPU), so just quickly unscientifically: Texas Instruments OMAP4460 (in Galaxy Nexus at 1,2 GHz): 2047.7 BogoMIPS 1.7 GHz Xeon from 2006 (the small EC2 instance, single-core): 5203.55 BogoMIPS Would be interesting to see some real benchmarks though..
- justincormack 15y agoYou dont want flops figures - no floating point is used to compile. Bogomips lives up to its name. I suspect that compiling has fairly poor locality and is quite cache dependent, so you might be better off just benchmarking on a mobile cpu.
- xal 15y agoNot a great test either but better then the above: Geekbench 2 on iPhone 4S: 617 Geekbench 2 32bit on iMac i7 @ 2.80GHz: 8557
