Any universal benchmark apps?

[Fiann]

Just wondering, has anyone created a universal app capable of running cpu benchmarks on Windows/Phone 8.1 devices? Or even separate apps that use the same methods? I was just thinking that it could make for some interesting comparisons.

GFXBench was recently released and it's a universal app (However the app did crash when I first ran it)
