3DMark Time Spy
3DMark is the latest version of this hugely-popular synthetic benchmark. Making use of DX11 features such as tessellation, compute shaders and multi-threading, it provides modern-day results and is available as a free download.
Maybe the conservative real-world clock frequencies are the main reason why the Asus Strix has an almost-perfect record in the stability test, which evaluates the differences in performance between 20 runs of the benchmark.
