Performance Megathread

[CPR]

5800X3D owners probably wouldn't get much benefit (10-15%) but who knows until it's benchmarked.

I'm not sure how the various Zen 4 models of X3D will compare. My guess would be that the difference in games specifically will be marginal.

ISSUE FIXED:

I was able to fix the framerate drop issue by changing the renderer to DIrectX 11. This causes the game to start in the wrong resolution, but alt-tabbing to the desktop and back fixes it.


I've been playing Stellaris for a few years now. Recently I built a new secondary computer with a Ryzen 5600G and I've noticed that if a window is open for example looking at a planets details if I zoom in a level or two while the window is open the frame rate goes from ~40 PFS to ~10 FPS and stays at the low frame rate until the windows is closed. When the windows get closed the frame rate goes back to the 40's. This is happens every time and is easy for me to reproduce. Is there a setting that will make this go away? I am using the iGPU of the Ryzen. I have a computer with an Nvidia 2070 and it does not display this behavior.

I watched this review of the 7950X3D and the reviewer mentioned it's by far the fastest CPU for stellaris. 5days per second in the late late game. from the screen: 2.5k pops in his empire alone

Interesting. Hopefully we can get someone who does a direct comparison to the 5800X3D. Very interested to see how the 7900X3D and 7950X3D stack up against it. Also the upcoming 7800X3D since it has less cache.

yes. i want to know so badly. ive got the choice between my mbp with an M1Pro APU or my pc with a R5 2600 and im kinda tempted to upgrade to the 7800X3D + 6000Mhz RAM once that one is available

I posted this https://forum.paradoxplaza.com/forum/threads/bencharks.1571249/ in the general pdx forum because pdx must be doing internal testing and they might as well help us out with our purchasing decisions.

And btw; the 7800X3D does not practically have less cache than the 7950X3D - in gaming mode the entire game is scheduled exclusively on the v-cache CCD for a 7950X3D, i.e. as if it were a 7800X3D.

Ah ok. Thanks for the explanation about the cache. I had read a bit about it but was confused as to exactly how it worked. So basically there isn't much reason NOT to wait for the 7800X3D if you're only focused on gaming?

if all you do is game then there's no reason to invest the premium into a 7950X3D at least for now since the current scheduling implementation cant dynamically take advantage of the faster clock speeds available on the normal CCD and as i said, the v-Cache ccd behaves probably exactly like a 7800X3D. If your workload includes applications that can take advantage of 16cores / 32 threads then it looks different. that could be streaming, that could be productivity related work.

The other thing that matters is picking 6000Mhz RAM since that's the magical integer 2:1 ration to the infinity fabric and offers the best latency vs throughput tradeoff; i.e. should run the best.

So yes, i'd wait

You may want to look into getting a 5800X3D, it should work in your motherboard with a BIOS update. I saw them yesterday for <$300.

yeah it's a pretty good deal at that price and i think it'd even work on my mainboard x470 mainboard but i expect a 7800X3D + 6000Mhz Ram to beat a 5800X3D + 3200MHz Ram by a quite considerable margin.

It should work. I have a B450 that originally had a 2700X that I upgraded to a 5600X. Tomshardware says the 7950X3D is on average 16% faster than the 5800X3D in gaming benchmarks . That's not much faster for a lot more money.

Level1 techs specifically mentioned that no other cpu runs stellaris remotely as well as the 7800X3D, but sadly no benchmarks. I'd expect the performance delta to be more along the lines of 30% from clock speed, IPC and faster RAM since stellaris is the kinda game which apparently benefits a ton from all that extra V-cache. the map games are very different in that regard from other games

 

[KarroK]

It's amazing that, after all this time, stellaris doesn't have an inbuilt benchmark like so many other games have, it makes it impossible to include the game in reviewers test suites.

Correct. For most games, 7800X3D with a cheap cooler and DDR5 memory is just fine. I suspect in late game Stellaris starts to push memory bandwidth more so probably don't get the cheapest DDR5 memory - AMD recommend DDR5-6000 as the sweet spot and that's all you should need.

Hmm. Good point.

Maybe we should raise this as a feature request?

I second this, I’d love to see a built in benchmark.

Dudes talking utra-advanced latest processors and here I am, playing Stellaris for the last three years with a Thinkpad T430.

Anyone else running Stellaris on a low-tier setup or are you all super rich gringos playing on your gringoputers?

He can upgrade to a 5800X3D for less than $300, how is that expensive?

Almost certainly, and I find it somewhat amusing how you called those using somewhat modern computer as "gringoes".

ThinkPad T430 at the time of release was a high price business laptop, but obviously it has dated over the last 10-11 years or so, though I assume you bought it used. Depending on when you bought it and how much you paid for it it might have been relatively poor choice even for a cheap laptop for any sort of gaming as T430 was not designed for gaming. Assuming you bought it around 2020, at the time, if my memory serves right, Intel was forced to respond to increasing AMD performance in laptops which resulted in huge performance increased compared to the older laptop generations.

From what I understand AI for Stellaris (and other PDS titles) is not deterministic so even with the identical start conditions the results are likely to be slightly different (eg. worst case is probably a huge war happening only in some of the runs). At best the benchmark mode would give approximation when repeated multiple times but there would potentially be far more variation than compared to 100% identical benchmarks. Obviously some sort of in-built benchmark would make it easier to repeat the tests as when I did my quick tests of 3800X vs 5800X3D I probably spent most of the tiem spent on reloading and restarting the game.
