ok so i've noticed that i'm not getting the best fps on some games (rust, escape from tarkov mainly)

here are my system specs -

Radeon Software Version - 17.8.2
Radeon Software Edition - Crimson ReLive
Graphics Chipset - Radeon (TM) RX 480 Graphics
Memory Size - 8192 MB
Memory Type - GDDR5
Core Clock - 1288 MHz
Windows Version - Windows 10 (64 bit)
System Memory - 32 GB
CPU Type - AMD FX(tm)-8350 Eight-Core Processor

Hi,
I wasn't implying he NEEDED a better CPU just that he's losing performance in most games relative to what he COULD be getting.

Now, it's worth noting that while 1080p tends to bottleneck the CPU more, raising the resolution (at same other settings) will always lower the FPS.

I would guess he's comparing his FPS to other people who have an RX-480 or similar and seeing performance is lower than expected.

*You can still have a great experience, for example maybe you run 60FPS instead of 80FPS. Is that bad?

On the other hand, he may struggle in some games to get the FPS he wants.

**also, getting a FREESYNC monitor at some point may be worthwhile (to game in the smoother asynchronous range) and then maybe upgrade the core system...

Yeah, probably the CPU.

It's easy to PROVE. Run a benchmark like Unigine Valley at the highest settings. That should use most of the graphics card.

Use a tool like EVGA Precision, MSI Afterburner as appropriate to monitor BOTH of these:
a) GPU frequency, and
b) GPU usage

The frequency should be near its top end (1400MHz?) and the GPU usage should be 95% or so. (except when switching between scenes)

That proves the GPU is working properly.

*NOW MONITOR BOTH of those in a game. You'll probably see low GPU usage and/or low frequency (not sure how it throttles exactly) which suggests it's waiting on the CPU.

Other:
You can also test the CPU frequency under load which should be roughly 4GHz just to confirm it works properly.

Long story short, it's probably a CPU bottleneck.

Every game is DIFFERENT but the above for Fallout 4 is probably the worst-case, and a good example of CPU bottleneck.

The FX-8350 is only getting about 60% of what the best CPU can do with everything else (GPU etc) being identical.

OTHER GAMES should be better. I couldn't find reliable info for the two games you mention though I do know RUST has severe CPU bottleneck issues.

Actually, that CPU can drop to 60% of what an i7-7700K can do for some games. I'd say closer to 25% loss on average but it just VARIES too much by the game to pin down.

OC the CPU if possible would help, but at best you can get up to the amount you overclock so jumping to a SUSTAINED UNDER LOAD 4.4GHz vs 4.0GHz is 10%.

Which means if you got say 40FPS in a game the best you can do is about 44FPS.

Isn't the 480 much weaker than a 980ti? So then there isn't a direct relation between that graph and the current situation. Since the 480 wouldn't get such high values regardless of GPU. So then the difference between let's say a 7700k and his CPU is smaller.

I don't get this fake idea of "you need a new CPU to run your GPU at maximum efficiency". Unless the game isn't optimized, a good CPU can still run anything, even with the 1080ti. Case and point, me. I have an old 4770k at 4.0 Ghz and I run the same or higher fps on Witcher 3 for example.

Ofc the old AMD is garbage compared to a i7, but you don't need the latest i9 or Ryzen threadripper to run games at maximum performance. Especially when he is barely running a 480 that couldn't achieve the performance of a 1080ti.

And we need the fps values. At the moment you're just speculating poor fps and we don't know how low. Or if they are even low at all.

Don't use a game like Rust, early access, to judge performance. I'd first look to a benchmark like 3dmark. Run that, get your score and compare to others with the same CPU/videocard. It's not exact but you should be in the same ball park.

An FX CPU paired with a 480 means I'd suspect the CPU isn't keeping up. Run a game while using MSI Afterburner or similar to monitor CPU and GPU usage while gaming. You'll probably see high CPU but not so high GPU usage. This means your CPU is holding you back.

You are wrong, it's not a fake idea that you need a certain CPU to run a given GPU effectively, that's a fact. The RX480 is still a fine card performing more or less on par with a GTX 1060 and that CPU simply cannot use it to the max.

It's fake that I need a 7700k to run my AORUS 1080ti. Since my 4770k runs same fps on benchmarks. Unless you take synthetic benchmarks into consideration for gaming, then yes, a 7700k would probably increase my 3dmark score a lot.

His CPU is much weaker than mine. That's different. But you don't need to upgrade every generation of CPU, unless they actually make a huge breakthrough.
And I've already had my CPU with a 780, 980ti and a 1080ti. Your argument is invalid.

There isn't that much performance difference between 7700K and 4770K and the 4770K is still viable today and run those two CPU at same clock speed you would only see like 5-10% difference. But there is a large gap between those I7 and an old AMD FX CPU and that old FX CPU will bottleneck that GPU.

The RX480 is getting old yes, but like i said it still performs almost on par with a GTX 1060 which is considered a good sweet spot for modern 1080p gaming.

Anyway, i agree that we need his FPS values to help him out. I see this a lot, i wish there was like a notice popping up on the screen before creating a thread to remember to post system specs and other relevant info as people seems to forget that over and over again.

THIS one isn't cheap, but it's just an EXAMPLE: https://pcpartpicker.com/product/c298TW/asus-monitor-mg279q

I don't want to confuse the topic so I'll just leave it there.
