5700xt varies highly on hashrate and power consumption depending on whether the vram is samsung or micron. most are micron.
They get more hashrate but also consume more power. The samsung ones run cooler, but their hashrate isn't as high, also they consume less power.
I suggest finding out what type of memory you have before doing overclocks. Also they are really annoying cards as stressing the vram will make them hard crash the computer. and you will need to perform a hard reset to get it working again. No remote restarts unless you have a smart plug. I'd suggest running any new overclock for like 24 hours to see if there's a crash.
They absolutely suck in the current gpu mining meta, but they used to be great during ethereum days, especially with TRM's r-mode. They were efficiency kings at some point
