Will upping resolution remove cpu bottleneck?

[kalo]

Hello, 

Im not sure if this is the right place to start this topic, as i am new to this, but here we go.

My current setup is a 6600k, 8gb DDR4 ram, h110 mobo, so no cpu overclocking aaand a Vega 56, upgraded last week from a R9 380 4gb

So i upgraded as i found a great deal on Black Friday, but it seems to me that my CPU is bottlenecking the system, GPu won’t hit max usage, CPU is at constant 100% and lag spikes are killing my enthusiasm in a bunch of games...

So now that i have a bottleneck in CPU after a GPU upgrade, i don’t really want to upgrade my CPU as i dont have that kind of money to spend, but i wanted to upgrade to a 1440p 144hz monitor. As it seems that 1080p is gives me a CPU bottleneck, will the 1440p remove that? I know CPU load doesn’t change but will the Vega 56 be the bottleneck in 1440p? I can also get a Z270 board and a Hyper 212 and overclock my CPU if that can help.

I really want to make the upgrade to 1440p but i just don’t want to spend my money and still have lag spikes and thus degraded performance.

yes but removing the bottleneck dosnt net you any more framerate

It may introduce a GPU bottleneck that is stronger than the CPU bottleneck (i.e. you'll be limited to an even lower framerate than you are now, because the GPU becomes maxed out earlier, before you get to the point where your CPU limits you).

 

So you cannot "remove" or "raise" the CPU bottleneck by increasing the resolution but you can avoid hitting the CPU bottleneck if that is your goal, by introducing a GPU bottleneck that will limit you to an even lower framerate, that is what resolution increase will do if you increase it far enough.

1440p will load off a bit more to the gpu, but I would recommend going and get a second hand z170 or z270 to overclock that chip a bit

Framerate should be good with the vega on 1440p i would assume

Yes. But a GPU bottleneck is to be expected in a gaming system and on higher resolutions, And lower fps when jumping from 1080p to 1440p is expected aswell, but my current monitor is a really bad 1080p so either way im in the market for a new one

Good recommendation, but maybe doing both of these things would be best, so if i can find a good deal on a monitor i’ll get a Z chipset aswell

yah its going to be pretty good, if you tune down settings a bit you can probably reach 144fps in most games

Yes, and no. If the games you are playing are esports titles, it will help a little, but your overall framerate will be lower.

You have a K series and a Z series so you might as well overclock, the 212 will give you a bit of headroom as long as you don't need too much vcore to stay stable. Overclocking will help though.

212? I would rather get a 33 esports one, but that's imo

I do not have a Z mobo yet, i said i could get one if it would help with the CPU bottleneck issue

Ah yes the 33 esports, but the 212 is 50% less expencive where i live

[voiha]

Kinda yes, what's happening is that if you're at 1080p 80FPS for example, and you're setting it to 1440p and you still have around 80FPS, then your CPU is bottlenecking the GPU, the GPU just works harder to maintain the FPS, you will see boost in performance once you pair the GPU with equivalent or more powerful CPU

Well, that's normal. Both are good coolers, but I like the esports one. @seoz might be able to convince you

Well i’ll be pleased with such performance on 1440p

The 212 (or the 212 evo) seems like a pretty good air cooler, and its not all that expencive and if i was to get the 33 why not just jump to a water cooler? I can’t test the coolers side by side and compare temps for myself, so if the temp gain seems reasonable i might consider the 33

Because you can't get a good aio for that price. Those are performing at best on par with the esports one

I run i5 6500 oc to 4.3ghz on a z170 with a gtx 1080 @ 1440p gsync I'm between 100-125 fps in titles like pubg. 

 

I defiantly recommend picking up a z170 mobo or z270 which ever you can get a better deal on. Even small OC to 4 ghz on all cores will help a lot. But a 4.5 ghz OC should be easy to get. 

Going to 1440p should help utilize your gpu more a have a better balanced load in your system with the OC. 

 

Everyone continues to talk about you max fps. Don't worry about that, it will be sold. Controlling your lows will bring you a much better experience. The OC will help with this so much it will be night and day.

 

I also recommend a freesync at 144hz 1440p 24-27 inch as getting bigger sizes start to look pixiled at if you not sitting farther away from the monitor.

 

A 212 cooler is fine. If you want something buffed up get a be quiet cooler

Ah thank you for sharing your setup as it would be pretty close to mine! I’m not concerned with max fps at all, i know those would be solid but the lag spikes and lows destroy my eyes atm... I’m waiting for a discount on a Aoc Egon AG241QX, it seems as a perfectly decent freesync 1440p 144hz panel and it’s the 24 inch  variant, as 27 seems too big and pixel density on the 24 makes it a lot sharper
