GeForce GTX 1080 Ti: Core i7 7700K vs. Ryzen 7 1800X Linux Gaming Performance

There's something wrong with the Tomb Raider Benchmark.
No way the 1080 Ti is pushing 160fps in 4k Ultra.
And no way the fps stays exactly the same between 4k normal and 4k ultra.
Other than that, performance difference between the 1800x and 7700k seems consistent with what I've seen elsewhere.
In gaming, Ryzen is hamstrung by its memory controller and has an IPC ~ 85% of Sandy Bridge which means ~ 70% of SkyLake/KabyLake
Given that the 7700k runs at 4.2Ghz (all core) vs 3.7 Ghz (all core) for the 1800x, that gives a theoretical advantage of ~ 65% to Skylake for gaming workload that don't benefit from more than 4 cores / 8 threads.
And that's pretty much what we see with Deus Ex MD (in 1080p), Dota 2, Civ 6 and Unigine Valley.
The gap is smaller with Unigine Heaven probably because it's taxing the GPU more.
It's also smaller for Metro Last Light because this game can benefit from more than 4 cores as show in a previous phoronix article.

This makes about as much sense as running a 16-thread synthetic benchmark on these two. Ryzen would destroy the 7700k in that scenario.Last edited by torsionbar28; 13 March 2017, 12:22 AM.

There [for Deus Ex], 1800X with SMT on gets 72%, and with SMT off, 85%.
Here, it is 59%. (SMT off not tested).
In many games there, the 1800X, even with SMT on, gets around 80% or more. And SMT on, at least with the current Windows scheduler, is a handicap since the Windows scheduler (and probably the games) don't recognize the SMT cores as virtual (not physical).
Most of the tests in this article are at the GPU-intensive 4K resolution, where the gaps should be smaller than in most reviews, even with the "Ti" version of the 1080.
EDIT:
The 16 game average for the 1080p resolution, in the above Windows test, is 83% with SMT on, 1800X vs 7700K on NVidia Titan Pascal.
For the 1440p resolution, which is closer to 4K, it is 90%. For 4K, it should be even higher.Last edited by indepe; 13 March 2017, 01:07 AM.

@Michael: but you didn't disable the turbo on both systems?
