Hi!

So a quick question.

I have been gaming on a PS5
I was going to upgrade to the pro, but for the crazy price I moved back over to PC gaming


I'm currently running a 4080. It's great, but honestly I can do fine with something less powerful.

This summer my apartment is like a sauna, it was honestly overwhelming


Gaming on the PS5 was doable, although it definitely added to the heat.

The 4080 is crazy hot, I'm actually holding off from turning on the radiator as it serves the same purpose.

When summer comes around again it won't be doable.

So it got me thinking.

The 5070 will launch early next year, I would sell the 4080 and still get a fair price, then get a 5070

To get an idea of things I started looking at the 4070.

What kind of temperature do you think I would hit, if I undervolted and underclocked it?

I think the PS5 draws on average 150w and hits a temp of around 50 Celsius max ( I might be totally wrong.

The 4070 draws an average of 180w max, and I'm unsure of temps.

I also run a i5-13600k, I would undervolt this

Would it be viable to have system draw the same if not less then the PS5, be cooler than the PS5 and also have a lot more performance?

Thanks for any input

Just use MSI afterburner and power limit the 4080. Doubt you will get whole system power less than 150w though.

It's got more cores so could theoretically have the 4080 performing better than the 4070 at the same power. 4080's also tend to have big coolers so better temps.

Also room heating up like that suggests ventilation issues. Worth looking into that as adequate fresh air has other health benefits.
 
Thanks for the reply.

I would get the 5070 rather than the 4070.

I'm pretty sure the 5070 will offer 4080 performance, with better power efficiency

I didn't think to undervolt the 4080 right down.

I'm also thinking longer term, so each time I sell a component I get a better price, as il sell just before the release of the next series.

Yeah I think a portable air conditioner next year

I'm not sure if you're aware of this already, but just for clarity.., the temperature really doesn't matter at all in reference to your primary concern of the conditions in your room.

In reference to power draw, from what I'm aware there are different versions of the PS5 so they might be different to what the reviews say, but 200 odd seems an oft-quoted number.

With the 5070, possibly, but the PC is going to have to account for the CPU, motherboard and the GPU, whereas those PS5 numbers I believe are quoted at the wall rather than just the GPU.
 
I figured if the PC is pumping out a lot of heat, it's basically a electric heater blasting away in the middle of summer

Ok, so with the PS5. The temperature there is for the whole thing.

Where as with the PC. There will be an undervolt CPU, still hot though.

Then the GPU, at whatever temperature. Then also the MoBo ( I hadn't thought of this component )

So the reality is that it will be creating more heat than a PS5. I bit more I can deal with. Just not a electric heater level of heat.

Just to clarify. I would be adding the CPU temp and GPU temp for the total temperature? How does it work?

See the post above me ^^

To give you an example:
- A CPU that produces 35 watts of heat but runs at 90c will still give you a cooler room than a CPU that produces 300 watts of heat but runs at 30c.

This here is exactly right.
Also, from experience with a 4070, it's very easy to underclock and get same as stick performance at around 110-130w for just the GPU
