GDDR6 vs GDDR6X : Understanding the Differences in Graphics Memory
GDDR6 is a type of DDR memory under the RAM category. Specifically, GDDR (Graphics Double Data Rate) is a type of DDR memory used for graphics rather than general computing. Unlike regular PC memory which is used to access data quickly through low latency, GDDR6 is developed to shift chunks of data at great speed which is vital in handling graphics and images in videos and games. This design helps graphics cards move a lot of data simultaneously, which is needed in order for rendering complex visuals.
GDDR6 vs GDDR6X - Explaining GDDR6X
GDDR6X is a more advanced version of GDDR6 engineered to enhance memory performance much further. While GDDR6 consists of high bandwidth for handling complex graphics in videos and games, GDDR6X uses PAM4, a faster signalling method to move more data per cycle. As compared to gddr6, gddr6x can move even larger chunks of data at the same time which is vital for even higher resolution graphics, faster frame rates and advanced features like ray tracing. GDDR6X provides significantly more bandwidth which makes it much more compatible for high-level gaming as well as professional and intensive graphic tasks.
