GPU Ranking

So I have been watching GPU prices drop over the past couple weeks on Newegg ,Best Buy, and other websites (Both Retailer and Manufacturer). I put up a poll a week ago trying to see the community's opinion on prices for cards and it was heavily favored towards RTX 30 Series which is understandable. So I started running some numbers to find the top 5 cards based on $/Mh, payback period, profit margin, change in margin, and efficiency.

To cut to the chase the top 5 cards are:

1-GTX 1650 Super

2-GTX 1660

3-GTX 1660 TI

4-RTX 2060 Super

5-RTX 3090

I will explain my methods along with some flaws that I hope some of you could aid me with.

Method-

To begin with I calculated each card's rank off of a score which is derived via a rank on a specific column. Each group is weighted to a varying degree based on my beliefs i.e.: $/Mh is the most valuable to me so I gave it a weight of 0.5 though this is a heavily volatile variable that change on a minute to minute basis. Margin change is a some what weird variable seeing as it heavily depends on expansion as the compounding of Mh over time ,but there are other variables such as electricity rates among different populations. Profit Margin however builds up Margin Change seeing as other cards like the RTX 30 Series easily beat out any GTX 16 Series by a land slide and this is simply due to efficiency with the chips themselves.

Known Flaws-

Pricing is easily this biggest issue seeing as there have been major drop offs in GPU prices, however I have noticed a couple factors especially on Newegg. To begin GTX 16 Series don't have much room to fall from this has been evident with the two leaders the GTX 1650 and 1650 Super with the GTX 1650 being at or around the $200 price zone. (Note as of writing there seems to have been a buying wave of the GTX 1650 S with only two available both of which are WAY above the price I found previously.) The RTX 30 Series however is seeing sellers trying to sell off inventory by beating their competitor by mere pennies. Yes, I know there could be a major difference between the actual price however I factored in the paid shipping because that is where they are making their margins. I wouldn't be surprised to see them drop another 20-30% over the next 90 days. RTX 2060 however is the most volatile with prices dropping and being bought like hotcakes.

If you made it to the end it would be amazing if you could drop your Hash rates along with Power usage for GTX 16 Series and up (I'm not using GTX 10 Series seeing as there is starting to be a higher failure rate due to age.)
