GDDR6X memory is a type of graphics memory designed for high-performance applications, particularly in graphics cards used for gaming and professional graphics work. It offers faster data transfer rates compared to its predecessor, GDDR6, allowing for improved performance in rendering complex graphics and handling large datasets. This memory type utilizes PAM4 signaling, which enables it to transmit more data per clock cycle. As a result, GDDR6X can achieve higher bandwidth, making it suitable for demanding tasks like real-time ray tracing and high-resolution gaming. Its efficiency helps enhance overall system performance in modern computing environments.
