Understanding GDDR RAM versus DDR RAM
Before delving into complexities, let's grasp the fundamental concepts of these two components. GDDR stands for Graphics Double Data Rate, while DDR stands for Double Data Rate, meaning data speed is doubled.

How are GDDR RAM and DDR RAM applied in real life?
Fundamentally, the main difference between GDDR RAM and DDR RAM lies in their different usage scenarios. In every computer, both the CPU (Central Processing Unit) and GPU (Graphics Processing Unit) require memory to perform their functions and tasks. And these two positions are also where RAM and GDDR RAM come into play.
CPU (Central Processing Unit) and GPU (Graphics Processing Unit) serve as platforms for RAM and GDDR RAM to exert their effects. Source: Technotification.GDDR RAM is used in graphics cards while your computer's CPU requires the assistance of RAM. The reason for the specialization of these components is due to the different nature of tasks performed on the GPU and CPU, ultimately serving the end user. As graphic processing demands higher data transmission, GDDR RAM is specially optimized for high-bandwidth needs to ensure optimal performance.

However, RAM can transmit small data portions with very low latency to ensure smooth operation of your regular computer tasks, such as opening Word documents, web browsing, or other tasks. (For those who don't know, a bus is a system that supports data transmission between internal components of a computer or between computers).
Distinguishing the Technology Gap between GDDR RAM and DDR RAM
The disparity between GDDR RAM and DDR RAM stems from core technology. Essentially, GDDR RAM utilizes a wider memory bus, ensuring that large data blocks can pass through at once.

This is crucial when considering the type of tasks GPUs perform, such as rendering graphics or ensuring seamless experiences in your favorite RPG games. On the other hand, RAM is optimized for lower latency rather than high bandwidth data transmission.

However, RAM is ideal for handling multiple tasks simultaneously. That's why you can open different applications on your computer and seamlessly switch between tasks. Apart from bandwidth, GDDR RAM and DDR RAM also differ in other areas such as power consumption and latency (GDDR RAM tends to have higher latency due to less strict timing than DDR RAM).
GDDR RAM and DDR RAM also differ in other areas such as power consumption and latency.It's also worth noting that there are different versions of GDDR RAM and DDR RAM with distinct systems, specifically DDR RAM being introduced much later than GDDR RAM due to control and governance by JEDEC (Joint Electron Device Engineering Council - Developing open standards for the semiconductor industry) along with many other manufacturers. For RAM, we have versions: DDR1, DDR2, DDR3, DDR4, and DDR5. GDDR RAM follows similar naming conventions but with some tweaks. Versions of GDDR RAM include: GDDR, GDDR2, GDDR3, GDDR4, GDDR5, GDDR5X, GDDR6, and GDDR6X.

Each type of RAM serves different purposes
GDDR and DDR RAM are both short-term computer memories with differences lying in their primary functions. GDDR RAM is integrated into GPUs for graphics-related tasks, while system RAM is connected to the CPU for regular computer tasks. However, both CPU and GPU communicate through the PCI Express bus.
