GPU working harder with new CPU?

[beany_bot]

I've noticed my GPU working much harder (read running hotter) since I upgraded my 4690k to the 3700x.

Does this make sense?

Yes, it's no longer the bottleneck and waiting for frames, it is now the bottleneck My 1080 is the same going from a 2600k to a 3900x. 1080 runs at 100% in everything now!

It's a lot louder!

It's the sound of needing a new GPU

***Also your sig has a slight typo, it's an R7

Well spotted! Had made that up before I cancelled my 3900x pre-order lol.

 

[Yaayuh!]

Yes, that's normal Your old CPU would have held your GTX 1080 back, now it can stretch it's legs and has become the bottleneck.

You have to factor in that it’s been fantastically hot outside in the last few days as well.My pc is running a good 10 to 12 degrees higher than it normally would .

True. But not so bad up here. House is usually 18, think it's about 24 now.

Your PC is like a doughnut conveyor belt. The CPU makes the rings and the GPU puts all the nice (eye) candy on.

Now that your CPU can make more doughnuts per second, your GPU need to step up the pace to keep up.

It's normal. If you put a framerate limit on to reduce unnecessary frames, it should help a little (ie if your screen is 60/120/144Hz, you don't need to be producing 250+ really for the vast majority of games).

 

[Terrorfirmer]

Perfect sense. It's like removing a limiter from an engine. Before this, with your old i5, the card was being heavily limited by CPU ceiling.

 

[Glanza]

You've taken the restriction off your GPU now so it's running at full speed now.

Time to get a 2080ti

Lol, I'll give Nvidia my money when they sort out their treatment of their customers. And their greed. I.e. not Turing!

5700 XT with custom cooler then Seems that's a pretty decent card and very energy efficient, for far less money than nvidia's 2070 super.

I would. But not a decent enough upgrade. I'll wait till AMD's card next year.

Yeah it's not a massive upgrade, but it'd definitely reduce the noise a lot. You could probably sell your 1080 for a decent price if you did decide to.

 

[theoneofgod]

Yes, as mentioned, you've unleached the GPU. Be happy about it (if you can).

If it's not in warranty or close to expiry, I can recommend changing the paste. Kryo dropped mine at load by 5c minimum. The benefit being fractionally better boost holding but mainly less noise.

I don’t think any card maxes out the new ryzen chips. My 3900 sits on about 7% utilisation when gaming with a Vega 64. Most of the time it’s just chilling on a sun lounger sipping a daiquiri.
