Cpu Causing Bottleneck?

Hello Guys, My system seems to be dropping a few frames in games recently (Alot in some) and I was wondering if it was down to my Cpu Bottlenecking. I've noticed that in games the Cpu is only using 50% of what it is capable of. I'm pretty sure this is down to my Gpu which is a very powerful card.

Specs:
CPU: Amd 8350 With Hyper 212 evo cooler
GPU: Gigabyte G1 gaming 980ti
RAM: 8GB Adata Ram and 8GB Hyper x. 16GB overall
PSU: 750 watt power supply

Also, If that is the case, Is there anyway to stop it happening without forking out money on new
parts? (Such as clocking down Gpu?)

Thanks :)
 
Solution
Clocking down the GPU wouldn't change a thing.

Can you list the games your having issues with please? (Also most games aren't very well optimized)

The CPU was released in October 2012 and that is old architecture...

AMD have really fallen behind in the CPU market, all the AMD people are waiting for ZEN but no one has any idea when they are coming

Intel is domination the CPU market for this present gen of hardware at the moment with their Skylake line, their Haswell architecture is still going strong (its only like 5-10% less powerful than Skylake really).

I am about to install an i7 4790K today as my i5 4460 is becoming CPU limited in games such as Fallout 4 and Witcher 3 as these games require high clock speed and 8 threads to...

I'm pretty sure in most games the Cpu is not fully utilised.

Assetto Corsa said my Cpu was only using 59% but that dropped to 52% by the end of the benchmark?

Gta V is a big one, Cpu runs at 48%

Just cause 3 Is probably a contender as well.

Cs:go sometimes seems to be Juddery sometimes (Probably between changing frame rates).

Your probably becoming CPU limited in some games now due to the old architecture, you may want to research into ZEN to see if maybe you will have a chance of keeping ur current board with ZEN or you may want to look into changing to Intel as they actually have new CPU's out that can handle any of the games out now which are mostly the i5 and i7 lines.

Hope this insight helped.

No it's because most games only use 4 threads to a high degree so half of your 8 core CPU is twiddling thumbs.

Thanks, I might try and upgrade at some point to an Intel Chip. Is an 4790k Ok? Or should I maybe get a skylake?
 


I just installed my i7 4790K last night and it is an absolute beast of a CPU!.

I loaded up Witcher 3 the moment I got to my desktop and I was getting across all cores and threads 40-50% (it was literally just sitting back while my old i5 4460 would be gagging) at around 60C with my cooler master TX3( this cpu requires and after market cooler otherwise it will throttle). I was getting a clean 60fps vysnced with GPU at high settings with ultra textures getting around 60% usage and I wasn't getting a single bit of stutter.

I tested all the games I have had trouble with such as:
-Borderlands 2 multiplayer 4 player match (ultra constant 60fps)
-Fallout 4 (high settings ultra textures constant 60fps with CPU cores at around 40%, either while overlooking diamond city)
-Witcher 3 (high settings ultra textures constant 60fps with CPU cores at 50%, played 3 hours so far)
-Overwatch Multiplayer (Maxed constant 60fps with CPU cores at like 40%)
 
Well why is it then that my i5 4460 is more powerful than his and was fine in practically 75% of games thou when I played the games I listed before I was getting 100% across the board on all cores, the moment I put the i7 in was getting clean CPU usage with no limitations.

Get an i7 and you will wonder how you even got on with your AMD CPU (I'm no Intel fan boy, Intel just seems to be the most powerful at the moment till ZEN finally comes out)

I should try and upload a video at some point

 


Well I don't think the person could really notice if they use the pc lightly, my old CPU could max my GTX 970 GPU usage in many new games without issues but when it came to big big games that's when I got into the issue.

Also I did ask for the poster to list the games he was having issues with, which he has yet to do so.

If he is getting sudden drops he could try reinstalling his CPU cooler and use new thermal paste as well just to be sure.

Also he hasn't really given any temps for us to go on.

The max temp of your current CPU is ~61C, if you hit that then your going to seriously degrade its life spam.

Hope this helps

I tried running Gta V online to see what temperatures I get whilst playing that (Gta V is quite choppy for me) but the Temperatures seem to be fine.

The Cpu topping out at 40 degrees.

One thing that seems strange there though is that It says my 980ti only has 2048mb of memory? I swapped out a R9 285x for this 980ti some time ago now... The R9 had 2048mb of memory.

And yes, It's mostly on big Titles such as:
Gta V (Cpu runs at 48%)
Just Cause 3
Etc.

But for some reason I also drop frames in:
Payday 2
Sometimes in Cs:Go (Probably jumping between frame rates...)

Also, The Cpu cooler got reinstalled a couple of weeks ago. (Hyper 212 Evo)

Sorry, Just to add, There seems to be a weird buzzing noise coming from inside my case somewhere but ONLY when I play intensive games.... I thought at first it was the Gpu fans but I turned them off just to test if it was them making the noise and it wasn't. Is there anything else on the Gpu that can make that noise? I'm pretty sure it's the Gpu making the noise...

When you say it only has X amount of VRAM di you mean while your monitoring the game? As the VRAM amount used will constantly change depending on what the game requires, the most I have ever seen a game use was Far Cry 4 at very high settings with 3.1Gb VRAM being used.

Or are you looking as some kind of hardware statistic software and it is showing less VRAM than you should have?

It's some hardware statistic software and I says I have 2Gb when it should be around 6Gb of Vram. I don't know if that's a possible problem...

And It says I have 2Gb all the Time.
