3080TI higher temps than 2080TI

[Black Dog]

Just upgraded to a 3080TI from a 2080TI and noticed that the 3080 seems to be running hotter than the 2080. I have the same game with the same res and settings exactly the same as before with a locked frame rate but the 3080 seems to be 5-10°c higher. Surely the 3080 should be running cooler with the same workload as the 2080 did?
Fan curve is exactly the same using MSI and both cards are x3 fans.

2080 was MSI Trio and the new card is Inno Ichill x3.

Probably more down to the increase in power draw and some other variables I'd imagine. (a 250watt last gen card to a 350watt+ current gen etc)

I've just went from a 2080ti to a 3080FE & It was the same, just put it down to the extra power draw too. I've undervolted the 3080 to 850mv @1900mhz. Makes a fair difference to both power/temps tbh

I suppose your right but I would have thought the power draw would be based on workload or would it draw more power in general?

Probably a poor analogy, but my take on it would be comparing a car that has a 2 litre engine and a top speed of 120mph, and a 3 litre engine with a top speed of 140mph.

They both do 70 mph, but the 2 litre engine will consume less petrol than the 3 litre, even though they're doing the same speed.

 

[Blackburn1982]

Have a spy at this, will give an idea of the difference.

But yes workload will affect the draw, the card is still going to be doing a decent amount etc so I would say the draw will tend to be always more than what your previous one was unless you say limit fps, undervolt etc which all kind of reduces the workload the latter coming at the cost of a reduced boost clock.

 

[Black Dog]

Yeah, I get what you mean. The card is taking on more power because it's more powerful.

IChill is 350W v 300W Trio? (MSI better cooling?)

 

[Black Dog]

Could be that yes. They are both monster cards and have 3x fan cooling. Maybe the MSI is better as cooling and the extra 50w pushes the temps up a bit. Still, I would have thought the 3080 would be more efficient considering it's newer and running the same frame rate as the 2080. Maybe the extra processes and transistors on the 3080 contribute the extra heat.

I have purchased every Geforce known to man and have never seen one being hotter than the previous.

the increased transistor count in the 3080 ti vs the 2080ti will make the newer card run a lot warmer plus the amount of cuda cores is more than doubled 10,240 vs 4,352 but the pay off is a fair amount more overall grunt vs your old card, although the power draws are around the same 300-320w the more cores will focus the heat thus making the newer card run hotter.

you need to have a look at case airflow, if setup correctly then you'll get similar results with your old card though at a bit more noise to accomidate the more power hungry card
