Cinebench
We used the ‘CPU’ test built into Cinebench R15 .
Handbrake Conversion
We measured the average frame rate achieved for a task of converting a 1.23GB 1080P game recording using the High Profile setting and MP4 container.
7-Zip
We manually archive a 1.23GB MP4 game recording to test the performance in 7-Zip.
Asus' Sabertooth Z170 Mark 1 shows solid performance in our range of CPU-intensive tests. There's nothing to show that the Sabertooth has ground-breaking performance, but it isn't noticeably trailing its competitors either.
That's about as much as we could realistically wish for.
