GPU at 100%?

[NickHere]

Hi guys,

 

 Recently I have gotten a new desktop, any game I play from low graphic to high graphic. My GPU is always on 100%. Is it normal?

 

Spec Of Desktop:

Intel Core i7 14700KF Processor

AFTERSHOCK Glacier Mirror 360mm Watercooling

Gigabyte Z790 GAMING X AX DDR5

Gigabyte RTX 4080 Super Windforce 16GB

32GB Team T Force Delta RGB 6000mhz (16x2)

2TB Lexar NQ790 Gen4 7000mb/s SSD

850W Deepcool 80+ Gold ATX3.0

Yes, you want to be using 100% of your GPU during games to maximise your FPS. It is only a concern when your CPU is at 100%.

Running 100% on GPU prolong will it shorten its lifespan?

GPU is supposed/designed to work at 100%;, unless it overheats it won't affect its lifespan

What is the most ideal temp for gpu?

anything up to 110C is fine for hotspot

Is it the same for AMD? My 6700 XT in my "Ultimate Death Heat Chamber Case" gets up to 100C hotspot sometimes and it really concerns me

Yes, 100C is fine, you can also up the fan curve if these temps worry you

 

Do you have any case fans/ventilation?

I changed the curve and undervolted, it's much better now

 

I did an ATX mod to a case from a 2005 Mac and the airflow is just BAD in a giant metal cube

This isn't really true. For one, there are many CPU intensive games for which you would expect the CPU to be doing more work than the GPU. For two, either device reaching 100% means you are at the limits of what your PC can achieve in that situation (or in other words "situationally bottlenecked").

 

However, I think what you meant was "There is no issue with your GPU running at 100%, provided you are happy with the performance." which I agree with.

Yeah that's what I meant, thanks for wording it better

not really?

 

you'd always want to avoid a cpu bottleneck,  gpu maxing out is indeed normal though and ideally you'd want nothing fully maxed out, but generally gpu at 100% is very fine *as long the cpu can keep up* .

 

 

what games did you have in mind that use more cpu than gpu?

 

don't doubt that exists,  but it's definitely gonna be the minority. 

 

basically if a cpu bottleneck happens often its seriously recommended to upgrade that cpu.

Up to 75C / 90C hotspot / 90C VRAM is fine

I admit that CPU intensive games are in the vast minority.

I'm of the opinion that it isn't the type of component (GPU/CPU/SSD/RAM) causing the bottleneck that dictates how desperately you require an upgrade, but instead it is just dictated by the performance of the machine and the performance level you want. Therefore imo "if a cpu bottleneck happens often its seriously recommended to upgrade that cpu" and "you'd always want to avoid a cpu bottleneck" are the wrong messages to be giving out.

I'd always go with "if you encounter any bottleneck (GPU/CPU/SSD/RAM), you should consider an upgrade if the performance of your machine isn't as good as you'd like it to be".

I'm not totally sure what you meant here... if the CPU couldn't keep up the GPU wouldn't be running at 100%... did you just mean "but generally gpu at 100% is very fine"?

(I agree that a PC is completely fine to be running flat out)

its exactly the right message,  gpu bottleneck can be alleviated pretty easily with settings,  cpu bottleneck you're most likely screwed and can't improve performance much if at all with settings etc (sometimes an overclock can help but its usually far from a perfect solution) 

 

just to be clear cpu bottleneck needs to be avoided at all costs if you care about performance at all.

same as above.  if the cpu cant keep up, your gpu may run at 100% often, but will stall when the cpu hits also 100%, hence cpu bottlenecks should be avoided,  gpu bottleneck is the normal situation and therefore preferred.  

 

 

 

tldr: basically what op is saying: "my car reaches its advertised speed limit, is that bad?"

 

its a really odd question in my view and the answer is "hell no, you want your car reach its maximum speed, doesn't mean it always has to go that fast but its good to know it can if you need it."

Still confused by your point here (sorry)

imo, while a GPU bottleneck can be alleviated with lower settings, it dosn't mean it is automatically less of an issue than a CPU bottleneck, as for me the severity of the bottleneck is measured by the difference between the systems performance and minimum the performance the user will accept.

I think we'll have to agree to disagree on this bit

well, look what im saying is that "generally" its better to not be cpu bottlenecked because its just a horrible experience. that there are circumstances where its acceptable doesn't really change that. its fine if you disagree but I'll keep avoiding running into a cpu bottleneck (because i already know how shitty it is) and will advocate for the same, simply because it's "generally" more preferable to not max out a cpu, especially while gaming and a maxed out gpu is just the norm in most cases (typically it means your cpu can keep up which is good)
