GDDR

(Graphics Double Data Rate) GDDR is double data rate (DDR) memory specialized for fast rendering on graphics cards (GPUs). Introduced in 2000, GDDR is the primary graphics RAM in use today. GDDR is technically "GDDR SDRAM" and supersedes VRAM and WRAM.

Each GDDR generation is faster and includes enhancements; however, although based on DDR memory, GDDR versions do not correspond numerically to DDR. For example, GDDR3 was based on DDR2 chips; GDDR5 on DDR3 and so on.

GDDR6
As of 2020, GDDR6 is the current version providing a 16 Gbps data rate instead of 13 Gbps for GDDR5X and twice that of GDDR5. GDDR6 also supports the same 32-byte read/write access as GDDR5. See GPU, DDR and SGRAM.
