Ryzen 3D Mark Fire Strike scores better with Power Saver profile

Sat Jun 17, 2017 8:01 am

...As opposed to High Performance, Balanced or the AMD provided Ryzen Balanced power settings profiles. Combined score is a pretty dramatic increase, I would normally get ~6,000-6,500 but now it's over 7,500:

Still true if you lower your overclock?

Yep.

CPU at 3.9, GPU at stock:

CPU at 3.7, GPU at 2000/5500:

So while combined score definitely seems to benefit more from CPU OC than GPU OC, it scores higher with Power Saver profile regardless.

For reference, this is OC'ed on both the CPU and GPU, but with High Performance profile enabled:

Come to think of it, does it do the same with Time Spy? I'd expect Time Spy to be far better at using 4-8 cores.

(Ryzen also supposedly learns from what it's been doing or sommat so I'd have to poke around myself.)

Underclock for more performance? I like the sound of that.

Multi-variate equations have multiple answers. The only way to be sure is to test all possible combinations in the exact same test mode and then spend a long time in the data analysis process.

Performance difference with Timespy was negligible between the different power profiles. I guess the theory is right now that in power saver, core parking prevents the CPU from cross shipping threads across the CCX.
