I would expect the Non XT to run at around 48MHs (36 CU vs 40 CU), don't know much about power usage in that case.
Nah Im running plain 5700...extra cores dont do anything for eth, and it will matter even less when miners are running wave32 code.
Yes, both 5700XT and 5700 have the same hashrate.
this is good to know
what is the best memory chip for this cards? elpida, samsung, hynix, micron?
or there is no difference in hashrate?
