Graphics Double data rate 5(GDDR5) and Graphics DOuble data rate 5X( GDDR5X) are two different types of graphics memory technologies.
GDDR5 RAM can transfer up to 8 GB of data per second. A number of companies, including Samsung, Hynix, ELPIDA, and Micron, make GDDR5 chips. It uses little energy and just needs 1.5 V to run. A new version of the GDDR5 was released in 2016.
The GDDR5x protocol and interface training sequence resemble those of the GDDR5, chip designers should find it relatively simple to adapt their memory controllers to the new type of memory. The use of PLL/DLLs is required for the QDR mode, also known as ultra-high speed in microns materials, hence there will be some design adjustments made to high-end memory chips.
GDDR5 Vs GDDR5x | Difference between GDDR5 and GDDR5X
- When compared to GDDR5X memory, GDDR5 typically provides less bandwidth. On the other hand, GDDR5x provides greater bandwidth.
- Data rates for GDDR5 memory are in the range of Gbps, While GDDR5X memory may have a data rate that is much greater, ranging from 10Gbps to 14 Gbps or even more.
- When compared to GDDR5X, GDDR5 is likely to consume more power, which results in a louder cooling system and higher heat output. In contrast, GDDR4X is used in high-performance graphics cards, It is a more power-efficient design that can result in a cooler and quieter operating environment.
- GDDR5 is suitable for a number of midrange and entry-level graphics cards. but GDDR5X is frequently used in more expensive graphics cards and delivers greater performance.
- GDDR5 has been around for longer and can be used in more graphics cards. Higher-end graphics cards often use the less popular GDDR5X memory type.
