since a lot of people in Germany have bought 'cheap i7' xeon e3-1231v3 here's the chart that shows that this cpu is a pretty good option for playing KSP. Especially that you often can find it used for a good price:)

I run this benchmark on a 1.2.2 clean install with my Laptop Lenovo Z50-70 with Intel Core i5-4210u. Isn`t it possible to upload the jpg spreadsheet here in this forums?

 

The performance on this low power cpu is quite bad. It runs at launch with ~13fps and drops to <5fps when staging. Surprisingly at about 100 secs into the flight the fps goes down to ~10fps even though the rocket`s part count is much less while at launch. It seems the high speed cause a lot of heating and aerodynamic pressure and this needs a lot of performace from the cpu. Sadly i can`t prevent the rocket flips over at a high of about 50 km.

The hardware monitor from Windows 10 and a third party program shows cpu workload only 40% at the beginning and goes up to 60% after a few staging events when obviously in a cpu bottleneck the whole time (graphic setting 1280x720 at low details, the GeForce 840m is bored during the benchmark to prevent bottleneck from this side). The cpu is a 2c/4t and KSP seems to use indeed only one core/thread for one vessel. After staging there are a lot of debris and the cpu workload increases so it seems the debris calculation make use of another core/thread.

 

I planning to build a Computer to get better performance a KSP and as cpu i going to take the i3-7350k or the i5-7600k and overclock it, it should be one of the highest possible single core performaces that is currently available. If the time is come i will run this benchmark again :cool:

Please don't get an i3 7350K, it's a $180 DUAL core

Yeah, i'm thinking i'll take the i5 7600k. Dual core, even with Hypertreading, seems getting old, and it's only 70 bucks under the native quad core.

Great choice! And you can overclock it to get even more performance.

By the way where can I get the rocket from the OP? The link doesn't work and I'd like to give it a try.

Yes, i`m going to take this unlocked i5 with an ASRock Z270 Pro4 mainbord and an EKL Alpenföhn Olymp cpu cooler. It should go up to 4.8 GHz or 4.9 GHz.

Just searched on curse forge "cpu performace" and et voila, there it is: https://kerbal.curseforge.com/projects/cpu-performance-rocket-stock?gameCategorySlug=shareables&projectID=220893

I haven't really maintained this since 1.0; they made a lot of changes that make the test not as useful. All of the parts remain loaded for a very long time when you're in the atmosphere, so for most of the flight there are still 600 parts being calculated, and the aero-effects when you start moving faster can really bog down any GPU-limited setups. You can see how the graph from @riocrokite is basically flat for the first half of the test, since all of the parts remain loaded. But the craft from Curse should still work fine, as long as you point straight up, and you might need to turn on RCS to help keep things more stable.

I was putting together a setup that could be tested in space and that would give a better indication of any multi-threaded gains in performance, but then I somehow misplaced the craft files. :o

Great idea, optimizing CPU is essential for surface bases and keeping them stable.
