Most in order architectures approximately double their performance per clock whe they switch to out-of-order.<p>Examples include cortex-a57 vs a53.  Alpha 21264 vs alpha 21164.  As well as many of the atoms until very recently vs core2 and similar chips.<p>With the various arm derivatives from qualcomm, samsung, and apple a under 2 GHz in order CPU doesn&#x27;t sound particularly impressive.  Especially when they talk about &quot;under 30 watts&quot;, that&#x27;s intel territory, not tablets let alone smart phones.<p>Trying to emulate arm and beat arm on price&#x2F;perf or perf&#x2F;watt seems like a long shot with an in-order mips64.  Similarly beating intel at price&#x2F;perf or perf&#x2F;watt seems exceedingly unlikely with lower IPC and a MUCH slower clock.<p>The only thing that makes these mips64 look good is the even slower previous generation mips.
