Totally depends on the workload, well threaded workloads with a desktop ARM clock speed of 3Ghz~ or so could perform quite well for say PostgreSQL if properly deployed, but yes - for an interpreted language with a strict GIL like Python it may not perform so well; having said that, Xeon professors are dropping in clock speed each iteration, where we used to see 3+Ghz perform, it's now common to see those processors replaces with 2.2Gjz max clock speed - yes the cache can be larger, there might be more cores etc but with languages such as python you quickly run into the single core maxed out problem pretty quickly regardless.

*edit: would be interesting to see an elasticsearch cluster running on a high clock speed arm cluster... I wonder how it'd run... (and yes I know it's not that simple)
