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...?)

 

[kerberos_20]

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
