Vega 64 Being bottlenecked by i7 4790k @ 4.5ghz ?

[iamcll]

As it says in the title i'm pretty sure my cpu is holding me back hard in some games in some areas by up to 40%, Just want someone to confirm this is the case, i've attached an example

Your cpu is not the bottleneck. 

 

In the first picture your GPU is being fully utilized. In the second, it isn't, but your CPU is still running at around 50-60%... so it isn't the cpu.

 

My guess is you have on vsync or similar which is causing your gpu utilization to be 70%ish

Nope This is v-sync off, I also have no framerate limits in my drivers or anything. the example i showed you is 5secs apart one looking at the sky one at the center of the map where stuffs going on.

 

I also get this in other games like witcher 3 in novigrad, The far cry primal benchmark etc. My pc power settings are also in performance so that's not holding me back too. Reason i think this is cpu related is due to the fact the %used is higher when the frame-rates plummet

Do you get this same issue in other synthetic work loads too? try running a few different benchmarks and seeing if the problem persists.

Have an actual issue with my cpu and a 1080. Wouldn’t seem as easy with that card though, comparing the two.

I've done other benchmark tests before with stuff like Cinibench, Heaven, 3D mark and i tend to not have any issues, This only persists in games with high potential framerates. I've had this issue since putting the vega 64 in my system. like 4-5 months ago when it came out.

It is unusual because with cpu bottlenecking I would expect at least 2 of the cores to be pegged at 99-100% to symbolize it (not necessarily the whole cpu would hit 100% because of how many threads certain games are optimized for.) I personally have a 1080ti matched up with my 4790k and have had no issues at all (but i do use vsync in non benchmarks because I hate screen tearing and play at 4k anyways.) One thing to try is to see if you can bump your overclock up a bit on the cpu (4.5ghz is toward the lower end of overclocks unless your using the stock cooler.) and if the average improves then you know that's whats holding you back. If you need to know my setting to achieve 4.7 daily I can get them for you when I'm back home tonight.

depends . that number is only total cpu usage . He might have half the threads pegged at 100% with the rest being idle. the only way to know for sure is to get per core usage

edit: nvm , i'm tired , didn't see those stats

[pyrojoe34]

A screenshot doesn't give a great idea of overall load since it might not be representative of the actual usage when you took the screenshot. Do you have a tool that will graph per thread use over a period of time? How often are individual threads hitting 100%? Thread 1 looks to be over 75%, is getting to 100% often?

 

How's your drive use during those moments? Is it bottle-necked trying to load assets to RAM?

That's something i've tried already, My cpu simply won't go over 4.5ghz while being stable. I bump it up to 4.6 and my gpu has better usage but i tend to get BOSD's, I can't remember the exact msg but something along the lines of a second core in the processor.... Something Something.. timings

You've got it backwards.  The GPU is maxed out, not the CPU.

Take a look at the 2nd Screenshot, When looking at heavy areas in games the gpu usage goes down while the cpu usage goes up, Most games most of the time my gpu is not reaching 100%

the image shows per core usage as well.

that would be really helpful to have a graph to see if the threads ever hit 100%

what voltage are you running to hit the 4.5 ghz? and what are your temps?

look at the second image where his gpu is sitting at 70% and framerate is lower than first image.

It doesn't matter that it's going up a bit.  If your GPU is hitting 100% at any point, that means it's being stressed to the limit.  You haven't shown any evidence to suggest that the CPU is hitting 100%.

 

From the limited amount of data you've given us, the GPU is the only bottleneck.  A 4790k is also an incredibly good CPU anyway.

If it was a bottleneck it would be at 100%.

1sec going to get some data by playing for a few mins

the overall cpu usage wouldn't show 100% since most games don't utilize all cores and threads. We are trying to figure out if in some situations the cpu has the stressed cores reaching 100% which is holding back the gpu. just because its not happening in one place doesn't mean it cant happen in other places.

[iamcll]

Any other data needed ? Also my temps never go higher than 75, Even during cinibench

50-60%... so it isn't the cpu.

A CPU can bottleneck other components even if it isn't max out at 100% for a matter of facts...

Not a single core got close to 100%.  Bare minimum one of them should be at 100%.  It happens whenever my 4790k starts bottlenecking.  Far more often it's my 1060 though.

 

There is literally ZERO evidence that his CPU is a bottleneck.  There is absolute evidence that his GPU is though.  It's like you're determined not to look at the numbers.

[iamcll]

Could this all be a case of my ram being to weak/slow to feed infomation ?

 

Also may i add if i use VSR to bump my resolution to 4k my gpu does get used up 100% while maintaining a somewhat stable framerate, Going to 1440p i still get like 20% gpu usage loss but maintain the same low fps numbers as in 1080p

doesnt seem to be the cpu hitting limits there but if you did want to hit the 4.6ghz full time you could try raising your voltage to 1.32. I found that is where mine was stable for 4.7 and it might be the difference to get you there. (assuming a normal upgrade rate most people haven't experienced issues running haswell up to 1.35v for daily use assuming you can keep thermals to acceptable limits.)

I'm not ignoring the fact that his gpu is fully utilized sometimes. The op was asking the question of what was causing it to not be fully utilized in other scenarios like the second image in the original post where it shows gpu at 70% where his frame rate isn't limited so you would expect it to force the gpu to hit 100% as it did in the first image unless there is something holding it back.

Thing hashes like a Beast and then you are gonna go tear it up mining with it or some shit. 

[iamcll]

Soo anyone else have any ideas ?

[Mick Naughty]

Could be a setting on the pc, or the game itself. Doubt that card is stong to enough to be a bottle neck unless the game is really using that much recourses and causing an issue.

Have you done any trouble shooting?

I've been trying months to fix this myself, It's not some pc power saving setting, And nothing appears to be wrong except the gpu not pushing out the usage it should, Also it's not just this game, Starwars battlefront 2, But also most others that are somewhat demanding, Crysis 3, Thehunter call of the wild, Witcher 3, Far cry primal, Doom, Total war warhammer 1&2, GTA 5 and dishonored 2.

 

Frankly at a loss here. Maybe i simply have a shit broken GPU.
