noob question-rx480-openCL-EthereumBF

is open cl, embedded within standard AMD GPU driver package?
cant find details on AMD site.

something about SDK 2.0...but looks like a really old link.

current driver.
Adrenalin Edition 17.12.1
CARD-Gigabyte RX480
Win10/64

also.....which has the steepest learning curve?
1. learning hashcat GUI (or is this even recommended as a first step into learning HC?) 
2. learning hashcat native:   Win cmd line

also....
is  KECCAK-256 version (hashcat) compatible with ethereum algo?
or should i be using SHA-3  or other variant?

thanks for getting me over this speed bump.....!

HC noob wishes all a Happy new year!

Thanks people!
