I assume rev 2.0 came after the regular version.
Newer one is AD102-301-A1 vs AD102-300-A1

Has anyone done any extensive research on the difference of these cards (Power draw, voltage, cooling changes, etc...?)
 
google search says 301 has reduced voltage, 1.07 compared to 1.1 on 300
I looked more and just found a VideoCardz article on this, does it mean a higher quality chip or less power draw? (some reddit user mentioned it does)

Or is just just Nvidia flashing a new bios into it with lower voltage
