DDR Vs GDDR Memory Difference between DDR and GDDR RAM Memory

DDR Ram is widely used in Mobile Devices like Smartphones, laptops, and tablets as well as in Big Gaint machines like Desktops, Servers, and Workstations. DDR stands for Double Data Rate and DDR Rams are used in PCs to store some essential data which is currently in use by the Processor or needs to be used shortly. GDDR memory is located just behind the GPU (Graphics Processing Unit) either in the Graphics card card in case of a Desktop or in the laptop in the case of the laptop. GDDR stands for Graphics Double Data Rate. GDDR memory also known as VRAM where V stands for Video, means Video RAM or we can say Video Random access memory. Before understanding the working of GDDR memory, let's understand 3D Graphics. Gaming is the best example of 3D graphics, in games we see a lot of objects in a frame. Each object has its own Geometry and Texture. Where Geometry means the polygons. To form any shape we have to draw a polygon and any 3D object is a combination of multiple polygons. Also, each object has its own texture file which is actually an image file. Better texture means better Graphics quality and Higher texture size. So we understand each object has its own Geometry and Texture which have sizes between som KBs to 100s of MBs. All these data are stored in GDDR memory, as we move the mouse and move the player in any direction, GPU takes all the texture files from GDDR memory and renders those frames. If GPU does this process 60 times in one second then we gen 60 Frames seconds, which means the powerful the GPU higher the framerates as a result smooth gameplay. Now we understand the working of GDDR memory. Now the question is, why do we can't use DDR memory instead of GDDR, why do we need special memory to store data required for GPU. For that let's get a basic idea of DDR memory. DDR memory is used to store data of active software, background applications running in the operating system, and data of the operating system itself. all those data are very low in size but extremely high in quantity. DDR memory is highly optimized for storing and transferring small but large amounts of data and GDDR memory is highly optimized to store and transfer large sizes but less quantity of amount of data as compared to regular DDR memory. If we use DDR instead of GDDR inside the GPU or GPU directly shares the system's DDR RAM, in this case, DDR ram was unable to deliver all those large chunks of data efficiently, there will be huge latency and higher power consumption as well. as a result, GPU will never perform in its peak because it was unable to get data on time. That's why we are unable to use DDR memory inside the Graphics card and GDDR memory as system memory. Both are experts in their respective work.
