I don't care about benchmark. I don't want to disagree with you. But can u define "runs it beautifully" it maybe because good tegra gpu or something else but '64bit' '4gb' 'benchmark' in Mobile device is just marketing gimmick. If they really want so give something good just give good battery lifeFew softwares- and the benchmarking software is Google Earth Pro.
Tegra K1 64 bit runs it beautifully compared to its Snapdragon comparatives.
