So 170watts at the system level to pull in an extra 10MH/s over a 5700XT that can do the same with 100-110watts. Looks like the miners are going to need some tweaking to get anywhere near 70MH without melting the memory. No stock on Amazon and Microcenter had low amounts so meh thus far.
it was running at 880mV and there was only a small overclock on the memory. 70MH @ 150w might be achievable
