Low fps Rx 470

[jordansocos]

I have a problem, I usually play minecraft, valorant, cs go, roblox and all these have the same problem, my fps is fluctuating or is only low, less than 60 fps, from what I read, my gpu can run many games with 60 fps, but mine reaches 15 fps has time.
My Settings:

CPU: AMD FX-8320
Memory: 8 gb
GPU: Rx 470 Graphics

yes you are right that only 4 cores are visible, but in principle there should be 8, but he may not have chosen to display them by turning on the after burner

but if we are talking about better performance, in my opinion, RAM should be fixed first, it should be able to work on a dual channel, XMP or D.O.C.P function should be included in the BIOS

An easy test you van do is look at what percentage both the GPU and the CPU are running at. I would suspect your CPU is bottle necking your system if your CPU is running at 100% an GPU is only say 20% that's the problem. Not much you can do about it other than close as many background processes as possible or an upgrade of course . FX series CPU's were not that great when new they are around 9 years old and not really up to the task>. Even low end Ryzens are way more productive or an i5 10600k.

As for the cores, from what I looked, everything was fine, I just didn't check the MSI.
So to sum up I must purchase a dual-channel RAM, and change the cpu?
Should I buy a Core i5-10400? Just to remind you that I want something more affordable ...

Adding the CPU frequency too might help, but we already can see a problem. FX-8320 is a CPU using CMT - it has 4 modules with 2 cores each, and cores within each module share FPUs and cache. For Windows it doesn't matter if it's a virtual core from SMT, a core with shared stuff from CMT, or whatnot. However, your screenshot only shows CPUs from 1 to 4, which isn't right for FX-8320 - it should report all 8 cores. So, apart from the other potential issues, we also have this - CPU is working only at half if its potential capabilities. I'm not sure how exactly this happened, but I'd start with checking out how many cores Device Manager and Task Manager report, and then I'll check if it's possible to enable all 8 cores from within the BIOS menu.
By all means, it sure is an old CPU, but it's not THAT bad. It should handle your games. Also the dual channel memory advice from other person is a good one - any CPU benefits from dual channel when it comes to gaming. This is even more important than usual for FX CPUs - one of their main bottlenecks is the memory bandwidth, which in your case is crippled even more. Installing a pack of modules of the same capacity in the corresponding slots (it's 1+3 and 2+4 on pretty much any mobo, but can differ in some models, so confirm with the manual) will definitely help your performance. It's a DDR3, so you're likely to easily find some nice deals locally - don't be afraid to buy used given you're checking before buying, as DIMMs fail quire rarely.
The third solution to your performance issues also comes from the memory bandwidth, only for this one you don't have to buy anything. Just overclock CPU-NB and RAM from the BIOS and that's it. FX with overclocked CPU-NB and RAM frequencies can outperform FX overclocked to 5GHz, as there's no point in OCing the cores if the data doesn't flow to those cores as fast as it should. Be aware that a lot of AM3+ mobos have issues with multiplier overclocking, so you might have to overclock the bus, and then scale down multipliers you don't really want to push, like CPU cores.

It's a shame most people here just go like "oh, that's an old one, throw it away". Not every problem can be solved with just throwing more money at it, and it certainly isn't the way the PC enthusiast should think. Should you invest some time in OCing - your CPU can run Cyberpunk 2077 better than last-gen consoles (8350 is basically the same model with slightly higher freq). https://www.youtube.com/watch?v=GQrXt_LA4f0

So it does recognise all 8 cores. Then it's all about memory.

Dual channel memory - yes, for any desktop PC it's a must.
Changing to a new CPU tho isn't that easy. Your motherboard only supports those old CPUs, so if you want to get a new one - you'll have to buy new mobo, new RAM, and likely new PSU as well. i5-10400 is an overall decent option, i5-10400F since you've got a graphics card already. You can also try Ryzen 1600AF - slightly worse and slightly cheaper. Both will provide decent performance for any game out there. Or you can scale down to i3-10300/Ryzen 3100 - they definitely will play the games you play just fine, but might get overwhelmed by a next-gen games of years to come. I'd definitely go with 6-core once since the price difference is not that significant.

The issue is the lower end FX8320 and its very low core speed, combined with Single Chanel RAM and only 8GB.

First, if you can, get an OC on the CPU. At such low core speeds anything you increase will be felt. Try to get to an all core of 3.8-4.0 or better. If you can pull an all core of 4.0 you will be up to sock 8350 speeds... I know that doesnt sound like much, but, for FX you can and will feel and see massive uplift from 3.5 to 4.0 all core. There is a reason why anyone who reviews FX8 chips, even lower end ones, goes for a minimum 4.0 all core and its because its more or less needed for anywhere near 60fps averages.

Getting another stick of ram for DC and 16GB total would be the next thing to look into after the OC.

Your GPU sits between the 1050ti and 1060, splitting the differenece between them on average. With a 4Ghz OC your CPU is close to a locked i5 6400 in performance. So if you cannot find an apples to apples FX8/470 combination you can get *very rough* ideas on performance from a "comparably" equipped 6400/1050ti combo...

But without a CPU overclock to 4.0+ and without DC RAM you wont get near that in real world performance.

If you move to modern games ^ but again the FX8xxx is more than enough to run csgo.

just to let you know all these years later. openGL has massive driver overhead issues with any architecture prior to RDNA2. i get 51fps dips on a vega56 in A.W.O.L. eDuke32, openGL Gzdoom games. thats just how AMD ran, poorly. when gpu bound it runs good, but even on vulkan, occassionally, since its not native vulkan code, the way AMD drivers interact on certain architectures with certain game engines causes insane issues. if you want decent openGL performance from AMD you simply gotta upgrade, or go nvidia. i run a 5800x3d and it cant get a vega56 past 50%, being cpu bottlenecked due to opengl driver overhead. while in others where drawcalls and such are optimized more, the driver has little issue and the cpu can push the gpu to the limit. the issue here is amd´s drivers. plain and simple. but also you overburdening your cpu in the first place with too high a render distance. and then there are occassional amd opengl renderbugs.
