Hi guys I inherited a 3770K system that has literally been sitting for about two years, I plan on rebuilding it and making it pretty darn cool but currently it has been broken for two years and last night I just got it running again. It Has two XFX R7850s in crossfire in it...  does anyone have a clue what the PPD is on that? I mostly use Nvidia cards and I know this is a very old set of cards now but I also know they’ll still fold. Would it even be worth trying to get it to run for a while? How do they perform against the slowest video card I have folding which is a 750TI? Thanks

86K PPD, from a sample size of 16 users.

@Metallus97 last week linked this forum, where people can submit their PPD on various pieces of hardware:

https://www.overclock.net/forum/55-overclock-net-folding-home-team/475163-gpu-projects-ppd-database.html

And there is a spreadsheet linked there which shows the different PPD numbers for the given GPU's. The 7850 seems to get around 86K PPD (depending on the WU of course).

They should give you about 85K PPD per card, according to the GPU database:

https://docs.google.com/spreadsheets/d/1vcVoSVtamcoGj5sFfvKF_XlvuviWWveJIg_iZ8U2bf0/pub?output=html

 

I would, however, expect some variation between that database and the actual performance of the cards due to differences in things like clock speeds and power limits.

Good to know I think that’s roughly what my 750 TI gets I think I’ll plug it in and run it for a few days
