CPU upgrading from i9-12900K worth it?

[jollyjack]

Hi. Got a DDR5 MSI Edge 790 MB (not the i version). 64GB DDR5, 3080ti RTX.

Was just wondering if upgrading my CPU from a i9-12900K to a 14900K or KF is worth it.

Test comparison sites show about 12% general speed CPU improvement. 24 cores versus 16 on the 12900K.

 

One reason might be that complex missions can usually only be played up to 2x, maybe 4x, hate long nothing to do "virtual flights"

What does your core utilization rate look like with the current CPU? If you're not currently maxed out, then your data bus or the game code itself may be the limitation, not your CPU.

Hi, you mean this?, only 6% while IL2 is running with heavy load of planes:

 

 

How can you improve that BTW?

I turned on windows game mode again (was advised to turn it off with DCS). CPU use improved 'till about 14%

It does not look like any part of your current system is being challenged by BOX. You may want to upgrade your hardware for other reasons, but IL2 performance improvement probably isn't a valid one.

How about this usage rate?  Have good fps and no issues really.

GPU use is around 90% with IL2 running, 3080ti Aorus extreme. I set fps high and 144Hz 4k monitor.

The important number for IL-2 CPU performance is the SingleThread index:

The CPU% utilization reported by Windows is meaningless, since it is just the average load of all cores. Your CPU could be the bottleneck I you might still see low numbers around 5-20%. IL-2 run in several threads but there is one thread which is the heavy one and it can not use the multicore capability of most of CPUs.

 

 

 

 

Why do you want to run it at 144Hz?  is there any other lower freq on that monitor?

[jollyjack]

144Hz, could try lower, but it seems a nice and non-flickery display that way. A fast Acer Predator 4k monitor.

PS i just bought a better class Displayport cable than the one that came with it, really makes a difference on flickers i had especially running IL2.

Going from 12 gen Intel to 14 is not worth imho. What is worth is going to AMD Ryzen 7 7800X3D. It's best value for money. Then performance in games also is phenomenal for half the price. I'm Intel guy but pragmatical. 

[jollyjack]

Pricewise a good tip. But i still don't trust AMD after a 3 year old laptop with it blew up in my face ... no warranties, sorry sir.

And on top comes anew MB lol ...

For sure new mb is additional cost, if you don't have to buy to upgrade, I understand that it's better to stay with Intel.

I have same issue with trust but how do I know if that change if I don't try.

Is the OS graph by Logical Processors useless?  I'm not seeing any one core much higher than any other while in IL-2.

This was an offline quick mission dogfight with 16 aircraft with clouds.  Probably not the highest strain on the system but I expected to see one core higher.

Yes, that per core graphic is as useless as the CPU% utilization number.

The tricky thing is that the heavy thread is jumping from core to core (Windows manage that) and it is not represented there.

 

Look at this post and the sublink in the post:

 

 

In VR we have the fpsVR tool to provide the CPU frametimes and GPU frametimes. But I have never seen a similar tool for monitors. Does it exist?

[LLv34_Flanker]

S!

 

Would not upgrade your CPU, still eats games for breakfast. And the new Intels require a hefty cooling solution plus a beefy PSU. If upgrading anything a 4000 series nVidia GPU maybe.

 

I am still using "old tech" aka AMD 5800X3D CPU. No issues in any games and more than enough FPS with the Radeon 6950XT card. Was looking for 7800X3D CPU but investment required vs performance gained was not worth the hassle.

I wouldn't put any stock in userbenchmark.com, its notorious for skewing to Intel. Some anti-AMD bias for some reason. 

 

That's not the only topic, just an example.

 

I went to AMD for current CPU back in 2021, 5800x, after being on Intel since 2003. Its been a great platform. May upgrade to Zen5 when it drops.

 

With Intel and the P+E cores, may want to look into Win11 as it has a better scheduler to make better use of that core layout.

[LLv34_Flanker]

S!

 

Noticed same about Userbenchmark site. Horrendous anti-AMD sentiment in everything. Biased heavily on praising Intel and nVidia. Shame really. Therefore I have read mostly Guru3D for tests etc. No favor to any brand and uses wide range of software in testing.

 

Regarding gaming and CPU. While fully understandable VR needs a beefy setup it sometimes feels like games have just become bloatware and developers(in general) too lazy to do the slightest of optimisation or utilizing more than one Core etc. We have CPUs with 6-16+ cores and yet games run on one core screaming at high GHz..while rest of cores basically idle. Why?

 

End of rant. Basically you need only the latest and greatest hardware for 4K, RT and VR aka enthusiast level. For 1440p you need less investment yet it still looks good and in flight sims 1440p with a 32" screen is quite nice combo(dot visibility etc).

 

Happy holidays everyone?‍?
