Editing DDR SDRAM Memory

GDDR5 to GDDR6

GDDR stands for Graphics Double Data Rate

Graphics Cards (GPUs) 

GDDR6

VRAM (or additional VRAM) 

Moving from GDDR5 to GDDR6 doesn’t change this functionality, but GDDR6 is an upgrade to GDDR5 in nearly every relevant metric.


GDDR6 also boasts higher capacity per module than GDDR5. While a GPU actively makes use of as much VRAM as possible, that VRAM is split into different modules. GDDR5 comes in 5 different sizes: 512 MB, 1GB, 2GB, 4GB, and 8GB.
