It's also $1000 USD and the benchmarks AMD released today assumed you're using an AMD 5000 series CPU and new motherboard.
I think the 6800 is going to be the good AMD card for mining as of right now.
the 6900 is 1000.
the 6800 is 649.
if the 6800xt does 100mh and 180 watts it will be a great miner.
if the 6800xt does 90mh and 200 watts it is okay.
It also needs to be available.
I almost got a Nvidia 3080 at Best Buy today. but it locked out of the cart,
I was able to get two 3070 from microcenter this morning.
been playing with one.
I'm getting @59 mh eth at @108 watts from the wall for the card (Kill a watt meter reading)
Not quite sure how you are getting @108 from the wall. but that is better then the 5700xt which will do 52 at 103 which is simple's reading so that is 121 at the wall, if you get a good one.
now one of them costs 500 the other costs 420.
So that is very close in quality to a 5700xt power color red dragon
it would take a while but 7mh is 7 x 2.5 cents or 17.5 cents a day and maybe 2.5 cent in power so for mining eth 20 cents a day better and that is 400 days to make up the price difference. since warranty is for 1000 days. you can say it is a tiny bit better.
the 3080 looks to be a clear cut above the 3070
