What is GDDR?

GDDR (Graphics Double Data Rate) is a type of high-performance synchronous graphics random-access memory (SGRAM) designed for use in graphics cards, game consoles, and high-performance computing. It is specifically tailored for memory-intensive tasks like rendering textures, framebuffers, and other graphical data. GDDR memory achieves high bandwidth by transferring data on both the rising and falling edges of the clock signal, effectively doubling the data transfer rate compared to single data rate (SDR) memory. Several versions exist, with successive generations providing increased bandwidth and improved power efficiency (e.g., GDDR5, GDDR6, GDDR6X).
