GDDR5
GDDR6
GDDR5 was the dominant graphics memory standard from its 2008 commercial debut through the mid-to-late 2010s, running a 32-bit bus per chip at data rates that grew from around 3.6 Gbit/s at launch to 8 Gbit/s in later products, before GDDR6 began succeeding it.
GDDR6, standardized by JEDEC in July 2017 and reaching mass production in early 2018, doubled data rates over GDDR5 to as much as 16-18 Gbit/s per pin -- the current mainstream graphics memory standard for most non-flagship cards.
