I'd expect something under 5W. What's the official TDP for it? For example, here's JtR 1.8.0 built with "gcc version 4.8.2 (Alpine 4.8.2)" running on: model name : Intel(R) Pentium(R) CPU N3530 @ 2.16GHz http://ark.intel.com/products/81074/Intel-Pentium-Processor-N3530-2M-Cache-up-to-2_58-GHz Per Intel, this quad-core x86 CPU has TDP 7.5W, SDP 4.5W.

Surely ARM should be more energy-efficient than x86, especially at the lower clock rate, so perhaps your CPU's TDP is below this one's 7.5W. On the other hand, it's 22nm (Intel) vs. 28nm. > > Can you please add these benchmarks to > > http://openwall.info/wiki/john/benchmarks along with precise JtR version > > info? > > Done. Please let me know if anything is needs to change. Yes: I think you wrongly stated that you ran 8 threads. I think you only ran 4. If so, please correct that little detail. Thanks! Alexander
