More CUDA cores = more PPD...yes?

[WhitehawkEQ]

I was going to say the GPU core frequency, there is about 1GHZ speed difference between the 3080 and 4070.

4070Ti vs 3080Ti ppd. Suspect most of the difference is related to the GPU core frequency.

When there are sufficient cores to load the entire wu, the extra cores are idle.

The 4070Ti boost frequency is more than 50% higher than the 3080Ti.

Most of the ppd comes from the Quick Return Bonus, which is not linear.


Just checked a few of my GPUs (values will vary depend on the project)


3070Ti (MSI Suprim) folding at 2025 MHz, 68C, 230w (power limit set 230w)

3080Ti (EVGA FTW3) folding at 1845 Mhz, 71C, 280w (power limit set 280w)

4070Ti (MSI Suprim) folding at 2955 MHz, 64C, 218w (powerlimit set 235w)

Thanks @HayesK , those are the answers I was looking for!


Gotta 4070Ti sitting in my shopping cart!

I may let this purchase sit until after this CC billing period, our upcoming trip to Vermont is costing a bit north of $3K...

You can tell the truth Tim....The wife got to you...

Dave, Actually there's a method to my madness, goes like this: since the $3K trip to Vermont is the wife's idea, there will be no room for disparaging my measly little expenditure for the 4070ti.

So, you and your wife work the same as me and mine, though usually in revers: 'well hunny, since you just blew nearly 10 grand on GPUs, do i get my new car now?'

Exactly!
