GDDR4 is a type of graphics memory designed for high-performance applications, primarily used in graphics cards. It was developed to improve data transfer rates and reduce power consumption compared to its predecessor, GDDR3. This makes it suitable for demanding tasks like gaming and 3D rendering. One of the key features of GDDR4 is its ability to handle larger amounts of data simultaneously, which enhances overall graphics performance. Although it has been largely succeeded by newer memory types like GDDR5 and GDDR6, GDDR4 played a significant role in the evolution of graphics technology.
