YOU CANNOT COMPARE CPUs simply by comparing the system clock!!!!!!!!!

Totally agree that CPUs can't be compared solely by system clock, but given a comparable instruction set (i.e. both the systems takes x cycles for a divide operation) you can compare CPU speeds. For instance two CPUs on a x86 architecture using let's say, intel instruction set, one at 1.4GHz and one at 2GHz. The 2GHz would surely be faster in processing the same piece of information than the 1.4GHz.

CPU speed isn't a pure marketing hogwash. I do agree that it should not be the only metric to look at when comparing system performance.

Anyways, coming back to the point :

Are you saying that a 1.4GHz ARM Cortex A7 quad core android dongle does not have enough processing capability to transcode on the fly ??


Would love to hear views from some other experts too.
