Core i7 7700K vs. Ryzen 7 1800X With Ubuntu 17.04 + Linux 4.12

[aufkrawall]

acpi-cpufreq ondemand butchered fps in some 3D applications like Unigine Valley compared to intel pstate powersave on my 2500k. So it's very likely that the Ryzen CPU runs very disadvantaged in games.
If you want a fair test, please set every CPU to acpi-cpufreq performance instead.
(Intel likely would still be quite faster in those tested games though, they are no multithread jewels.)

I notice the exact same thing. ondemand kills FPS. I asked about this earlier in the thread but have not received a response from Michael about how he tested.

It's acpi-cpufreq ondemand for AMD according to the first page of the article.

pointless comparison. 1800x's competition is $1100 6950
if you feel urge to compare 7700, compare it against 6950, not against two times cheaper ryzen

[pal666]

I bought a 1090T with the expectation that all games would fully utilize 6 or more cores in the future and I was wrong. Now I am looking at getting a 4 core CPU to replace it

lol, you want to be wrong two times in a row

Just rebench Tomb Raider on nvidia again, AFAIR on nvidia hardware and driver Ryzen was much faster, while on amdgpu driver Kaby is much faster.

And it seems both times we are famous 60% alcoholic at FullHD and on bigger res diff is even worse

Performance per core still matters as some of these benchmarks show.

Only some of them. Considering how threaded software is becoming more common and my needs Ryzen still looks like the ideal solution.

[wizard69]

Exactly. Even multi-threaded applications will have their threads limited to the performance of a single core. The I7-7700K and I7-4790K still rule in single thread performance. It doesn't fit well into 'more is better' marketing though.

More often is better. You can easily see this where AMD wins, sometimes by a large margin. this doesn't even consider users with a lot of processes running at the same time.

[carewolf]

AMD needs a better prefetcher.

Well, and a proper 256bit-wide AVX unit. I am guessing that is also a pain point for games that are likely to try to use any vectorization they can get.

Michael Can you please do another bench on the 1800X with the Performance governor rather than OnDemand - It might yield some rather interesting results - might not. Either way, it'll be good to know
