Been gathering / parsing / analyzing data for a bit now in an effort to quantify how much of a difference things like GPU overclock, CPU horsepower, PCIE bandwidth, average gpu boost clocks, gpu memory speeds, etc affect PPD.
Still have a long way to go before I can confidentally make any conclusions, but I feel I have gathered enough data now that it's worth sharing with you all. It has been a lot of work to get it this far as I've been doing most everything manually, so I apologize for some data not being included, but I've been refining my process and significantly reduced the amount of time it takes to parse out the data I'm interested in. I've currently been focusing on getting the average gpu clock speed as high as possible on the single Asus Dual 4070 Super I have in my main rig and comparing those stats. But the main goal is to quantify the impact that the things listed above have so we can squeeze the most PPD out of each card for the least amount of money.
The major variations @KeeperOfTheButch and I have observed between my system, his main system and his dedicated folding rig is really what started this. We were seeing as much as a couple million ppd difference between our two rigs. I recently got a hold of one of @KeeperOfTheButch 's log files from his main computer which has helped tremendously and will be getting one from his folding box tonight. What is nice is that he has 4 of the same 4070 supers (2 in each of his rigs) so it's very easy to see impact things like PCIE / CPU / heat / etc have with the cards being consistant.

System specs related to the data in the spreadsheet:
Gary Main:
Ryzen 7 2700x overclocked to 4ghz
Asrock Taichi Ultimate motherboard PCIE 3.0, card running at x8 currently (have to move my raid cards to a different machine to get x16, but that'll be when i have time)
Asus Dual 4070 Super
Kyle Main:
Ryzen 7 7800x3d
MSI MAG x670e Tomahawk wifi motherboard
2x MSI 4070 Super Gaming X Slims
- Card listed as FS01 under the memory column is in the PCIE 5.0 x16 slot (running at PCIE 4.0)
- Card listed as FS00 under the memory column is in the PCIE 4.0 x4 slot
Both cards were at stock memory speeds for the data I've entered so far. The top slot card (FS01) had some issues with core restarts due to extra heat and that has since been rectified.
I'll update this with our observations thus far and theories later tonight when I have time. Not sure if this data is useful to anyone, but figured I'd share what we have so far. If any of you have any data / insight / observations on this stuff, please chime in.
