I'm surprised the gap isn't much larger.

I'm surprised the gap isn't much larger.
- wmf 17y agoWhy? 2.66 GHz / 1 GHz is only 2.66x; that means there's a factor of ten difference due to software and processor architecture.
- chime 17y agoThose are the max. speeds. In power-saving mode, I highly doubt the iPad runs at 1Ghz for anything.
- wmf 17y agoWhat's the point of having a 1 GHz processor if you never run it at that speed?
- cma 17y agoIt could be that for short bursts (which usually come immediately after user interaction), they use the full clock speed, but for long running computations, they throttle down.
- tdmackey 17y agoIt's a very common process to reduce heat and power consumption. For instance all the previous iphone and ipod touch underclocked their processor and the new HTC incredible underclocks. Just about every embedded device underclocks as a higher speed processor often runs more efficiently at a lower speed than a processor designed to run at that speed.
- wmf 17y agoIf the iPad never runs at 1 GHz then we have a case of false advertising. If the iPad sometimes runs at 1 GHz, just not when executing JavaScript, that still sounds like a mistake given the complaints in this thread about sluggish performance. (Disclaimer: I do power management for a living but I haven't used an iPad.)
