Okay, for those of you interested: Ryzen scaling with frequency is all over the place.
Some apps don't really scale at all, despite scaling linearly with Sandy Bridge (Cinebench king amongst these). Interestingly, the scaling issues are all related to multi-threaded apps. I've seen some weirdness in Windows 7 with multi-threaded scaling, so this may be a Windows 7 issue - changing to Windows 10 to find out.
AIDA64 skyrockets with higher clocks - showing ~25%+ higher scaling than anticipated... as in, they're showing that AIDA64 is useless for benchmarking Ryzen... and, yes, I'm using the latest beta.
One thing that does scale, in the real world, with frequency that is unexpected: memory performance. Usually changing the core frequency doesn't have much of an impact on memory reads and writes - maybe 500MB/s or so. I'm seeing 35GB/s changing to 43GB/s going from 3GHz to 3.8GHz - and Geekbench memory scores jumping from 3500 @ 3Ghz to 4000 at 3.8GHz.
All my results are with no SMT and only one CCX enabled.
Frankly, the results are bloody confusing.
EDIT: Results make sense on Windows 10 - positive scaling is still seen, but only in memory-sensitive apps. Further, multi-threaded scaling is as predicted. Don't use Ryzen + Windows 7 - the grass is not greener.
