RTX 4070 + Core i5 8600K low fps

[lil_nap]

Good evening!

I seem to be have some low fps issues from when I upgraded to my new GPU ( RTX 2060 -> RTX 4070).
When I play Dota 2 (Max graphics) my performance seems very similar to what I got on my RTX 2060. 150 fps down to 80 fps in fights.
In World of Warcraft (Max graphics) when I'm in the main city I seem to average around 40fps where my task manager indicate that the GPU util is around 17% and my CPU is around 70%

When I installed the new GPU I ran DDU in safe mode and uninstalled / reinstalled all the drivers, I think either my PSU might be the culprit or I'm having some sort of CPU bottleneck.

PC specs:
GPU: RTX 4070 12gb
CPU: Core i5 8600k (stock) with AIO cooler
RAM: 16gb DDR4 2666Mhz (2x 8GB)
PSU: Thermaltake TR2 600W Bronze
Windows 11
2x 1440p screen connected

Any input or advice would be much appreciated!

99% sure its your cpu.

 

[Jaco52222]

got a 9900k cpu for you lol, or even i7 8700. can send me a pm if interested

 

[ChinaNum#1]

8600k getting choked -_-

I had a similar issue with a 4th gen I7 setup. I upgraded the GPU and didn't see much of an improvement in performance. My GPU usage was hovering around 80, 85% and my CPU was in the 60's and 70's iirc. I then enabled monitoring of each CPU thread in Afterburner and noticed that at least one thread was always pegged at 100% while another was consistently in the 90's. My overall CPU usage was only showing 60's to 70's but the CPU was bottlenecking the system. I upgraded the CPU and the GPU usage jumped to 100% and yielded much better performance in the same games.

Your GPU is awesome but your CPU is from the before times. I was there. I remember.

But yes, your GPU is literally napping while it waits for your CPU.

Thanks for all the replies and info, I feared the worst, ah well guess it was time for an upgrade anyway.
Looking at the Ryzen 7800X3D as a possibility then and it will probably be worth going to ddr5 when spending that much.
Thanks again!

If you go 7800X3D you'll have to go DDR5, there is no DDR4 option on AM5. But you won't regret it, it's a beast and apparently people who own one have massive dongs and people who don't are sterile. I don't know, that's the rumour.

Seems like I will have a massive dong in the Asian community going forward

When I play Dota 2 (Max graphics) my performance seems very similar to what I got on my RTX 2060. 150 fps down to 80 fps in fights.
In World of Warcraft

Sigh.

The lack of understanding with bottlenecking drives me fucking mad. (not angry, just insane).

Firstly, dota2 (source) and wow are both very dated engines.
I get similar FPS/dips playing on my 4080 vs my 3070 in dota2. its just a kak engine which hasnt kept up with optimization.

If you want to test actual performance, something like Doom Eternal is properly optimized. Not only is it a tad more modern than those games, its actually excellently optimized (unlike 50% games out there).

Secondly. Which motherboard do you have? What does your 8600k (assuming 4.3ghz at stock) boost to on all cores during more modern gaming titles? You'll likely get incremental increase if you are running Z board with a bit faster ram (wont see much difference past 3400 CL18). But again, a couple of single digit % add up.

FYI. I am running an 8700 with my 4080. Out of curiosity I "upgraded" to a 5950X, top end board, 4000mhz ram. Guess the performance difference?
1%. Only a single game showed a boost nearing 10% and that was F1 2020. All other games had zero improvement.

So no, at 1440p, your 4070 wouldnt be holding your CPU back unless you're playing on ultra low and a dated engine.

Run 3dmark and compare it to their database. You will easily see if its a normal score or not

Thanks for you advice, let me run Doom eternal to see what is happening.
My motherboard is the: MSI B360 A Pro and yes it;s stock so on boost I assume 4.3ghz, I don't think I can go for faster RAM speed due to my mobo

Yeah, unfortunately not. It might still be a cheaper upgrade (if at all) than going for a whole new platform instead.
So, if you had the extra cash, I would look at grabbing a Z370/390 and 3200Mhz CL1`6 (although...ram speed can sometimes be sus..) and you'll most likely benefit from those incremental upgrades without breaking the bank.

Also, if you have access to something like 3DMarks, at least Timespy (which runs at 1440p by default, and there is a 4k test) will give some indication of where your graphics score lands you (not the entire score / cpu; just compare fps to fps between the different existing results and your own).

@lil_nap

Something like this is decent
https://carbonite.co.za/index.php?threads/i7-9700k-gaming-pc.496174/ (I'd probably upgrade the ram, even if you dont need it immediately - might not even benefit from faster ram at all, but its still worth considering)

Sell your stuff for about R3500-4000 (Cpu, mobo, ram, psu/ case - really rough guesstimate)

Pop GPU and Storage in

??????

Profit.

 

[Areola Grande]

To add anecdotal evidence to this, I upgrade from a Ryzen 3700X to a 7800X3D and saw about a 30% performance increase in some titles at 1440p. Don't discount the CPU.

 

[lil_nap]

Thanks for everyone's input, waiting for Doom eternal to download to check what is happening. I tested with the Witcher 3 on Ultra and I got around 60fps with my GPU util hanging around 2%. I appreciate the advice to upgrade in a more cost effective manner, but I might as well save a little bit and get myself the AM5 kit with the 7800X3D then I will probably not have to upgrade that for a while, well hopefully xD

 

[Oops!!!]

Dota is as well optimised as the Post office. It doesn’t care too much about GPU but loves high clock speeds more than cores and loves fast memory even more.

The biggest performance boost I’ve gotten is from overclocking my CPU and swapping out my memory to the fastest my board could support.
With the faster memory it also alleviated that gradual FPS drop you get as a game goes on, where I would start off with 240FPS and after a 60min game it would be running around 100FPS.

The BP’s and treasures on the loading screen also seem to drag the FPS down while they active.

 

[lil_nap]

I can try and overclock my CPU to like 4.5ghz , but unfortunately I can't go for faster RAM with my current motherboard.

 

[aiccc]

Look for my posts about overclocking a 8600K

I think I got it past 5 Ghz with minor tweaking. dont remember if it was on air or water cooling.

Newer cpu with newer GPU is better, but one can tweak the older gen to achieve gaming perf on a budget.

 

[dash09]

Ditto on the cpu upgrade. My old cpu was a 7700k, paired with a 3080. Gpu was not breaking a sweat at all, I mean games worked fine but I switched to 13th gen i5 and fps skyrocketed up and remained up constantly, no more random dips. Not saying get an intel cpu, just that upgrading to a newer platform will be well worth it

 

[lil_nap]

I spoke with 0jo from Progenix, within my budget he advised on some upgrades that I will be purchasing from him.
Look forward to the new system. I also think upgrading to the latest platform will be worth it and even word on the street is I'll get a massive dong (maybe change my nickname to lil_tripod), so it's a win win for me.

AMD Inception Mitigations Can Lower Performance of CPUs By Up To 54%

The AMD Inception mitigations are now available which lead to major performance loses across various CPUs in a range of workloads.

Note there is limited quantitative real data that one can use to make a proper determination atm

So to add to the already stated facts above.
Last week I had to retire my wife's 7700k in a cheap mobo (Hogwarts ran at about 50 fps and Farming sim 22 at 48 fps @ 1440p) with a 3060ti

Enter AM4 setup.
5700x and a decent mobo (Hogwarts now sitting at 70fps and farming at 65ish)

What I really noticed was the random micro stutter is gone, so I'm guessing its that 7th gen that didn't want to play well with the 3060ti.
Honestly I'm a jealous cunt now because her stuff is better, but that's life.

Surely Farming Sim only requires a few FPW (frames per week) so you can check on growth? Never in my life have I checked on a plant 60x per second.

Have you tried to drive those unruly combine harvesters with stutter??
I will however contact you in Dec so that we can look at upgrading my system so that I don't feel left out.

 

[lil_nap]

Just want to say thanks again to everyone. Thanks @Oj0 for helping me out with the good stuff that I need!

frame timing can cause that micro stutter when your CPU or GPU are bottlenecking each other. I'd actually prefer a low FPS with better frame timing than deal with that micro stutter.

Definitely agree. It's why consoles are playable even though they're shit. Low, but consistently low, frame rate instead of spikes.

How is the PC performing post upgrade?
