Difference Between GDDR3 and DDR3

Difference Between GDDR3 and DDR3

At a breakneck pace, our world is transitioning to a digital one. Nowadays, everything is controlled by computers and technological devices. Everything, from a document to an individual’s identity, is now accessible in digital format. When it comes to document creation, everything is done on a computer via the use of the internet.

However, in order to operate efficiently, it is necessary to ensure that all of the work completed is correctly saved. In order to do this, several businesses are developing various types of storage and dynamic memory, the most prevalent of which being GDDR3 and DDR3 respectively. Both of them are incredibly similar, yet they are also very distinct in their own ways. They vary not just in terms of components, but also in terms of their intended uses.


Because DDR3 is used for CPUs, while GDDR3 is utilized for graphics, the distinction between the two is important. They are also distinct in terms of cost and speed of response time. Although GDDR3 outperforms DDR3 in terms of speed, DDR3 outperforms GDDR3 in terms of price by a significant margin.

GDDR3 is an abbreviation for graphics double data rate. In this case, G stands for graphics, which indicates that it is exclusively used for high-performance graphics cards. It is much quicker and more costly than DDR3 and is utilized in the Xbox 360 and PlayStation 3. It manifests itself in the form of chips that are not readily replaceable.

DDR3 (Double Data Rate 3) is a form of synchronous dynamic random-access memory that operates at a higher data rate than DDR2. It has been in use since 2007 and features an interface with high bandwidth. It is a kind of memory that is utilized by the system’s CPU and is quite inexpensive. It is delivered in modules that may be readily swapped and updated as needed. It is available at a reasonable price.

What exactly is GDDR3?

Graphical Double Data Rate 3 (GDDR3) is the computer memory that is used for visual processing. It has all of the characteristics of DDR2 as well as some advanced features not seen in DDR2. Among these sophisticated characteristics is a decrease in the amount of heat and power dispersion that is necessary. It was originally offered to the public in 1998. It is created by ATI, which is also known as the Radeon Technologies Group and is available for purchase. Additionally, Sony selected the Graphical Double Data Rate 3 (GDDR3) for the graphics memory of the PlayStation 3 game system.

The following are the advantages of Graphical double data rate 3:

  • It has the ability to reset the device. In other terms, it is referred to as the capacity to do a hardware reset. This will allow for the complete deletion of all data from memory and the creation of a fresh start.
  • It consumes relatively less power when compared to DDR2, which results in reduced heat dissipation overall.
  • It has higher stealth frequencies, which are advantageous in that they provide more accurate timing and boost throughput, among other things.
  • Graphical double data rate 3 is a simple device to construct.
  • Low pricing is always encouraged and taken into consideration, which is also true for this GDDR3, which can be purchased for an affordable price.
  • It is more responsive in terms of reading to writing ratio as compared to other models since its strobe is unidirectional and single-ended.

What exactly is DDR3?

If we look at the classifications, Double Data Rate 3 is a dynamic random-access memory that is synchronous, and it is also a kind of SDRAM (synchronous dynamic random-access memory) if we look at the types of memory. It is both quicker and more feature-rich than DDR and DDR2, and it is more expensive. According to the standard, it is a DRAM (Dynamic Random-Access Memory) interface. It has been in use since the year 2007. It is of the third generation and operates at a clock rate ranging from 400 to 1066MHz.

When compared to its immediate predecessor, DDR2 SDRAM, it is capable of transferring data at double the speed (Double Data Rate 3-synchronous dynamic random-access memory). PC3L is a label that has been applied to its modules, and it has a standard voltage of 1.35 V. It also features dual-inline memory modules with 240 pins, which makes it electrically compatible with DDR2 in terms of performance and efficiency.

It has the following characteristics:

  • It provides flight-time compensations at the system level.
  • It results in the introduction of CWL, which is CAS write latency, as defined by the cloak bin protocol.
  • Three, it incorporates calibration resistance that is quite precise.
  • It offers superior performance in terms of bandwidth, with a maximum speed of 2133 MT/s at industry standards.
  • When compared to DDR2, it also performs effectively at reduced power consumption.
  • It is calibrated for both READ and WRITE operations.

Difference Between GDDR3 and DDR3

  • GDDR3 is an abbreviation for Global Double Data Rate 3, whereas DDR3 is an abbreviation for Double Data Rate 3.
  • System storage is mostly DDR3 (Double Data Rate 3), with GDDR3 (Graphics Data Rate 3) being utilized only for graphics.
  • The Global Double Data Rate 3 (GDDR3), in comparison to the Double Data Rate 3 (DDR3), is much quicker. The reason for this might be that the graphics card’s storage requirements are greater than the processor’s requirements.
  • Due to the quicker characteristics, GDDR3 (Global Double Data Rate 3) is a bit more costly than DDR3 (Double Data Rate 3) and is thus considered to be a premium memory.
  • In contrast to replacing or upgrading a DDR3 (Double Data Rate 3), replacing or upgrading a GDDR3 (Global Double Data Rate 3) is extremely simple and may be completed at home by anybody.
  • DDR3 (Double Data Rate 3) is available in the form of modules, whilst GDDR3 (Global Double Data Rate 3) is available in the form of discrete chips.
  • Although GDDR3 (Global Double Data Rate 3) addresses may be written and read simultaneously, this is not the case with DDR3 (Double Data Rate 3).


The explanation for both of them being memory for keeping their respective objects in the system and creating programs that are appropriate for their capabilities is provided. Because the requirements for graphics and CPU memory are varied, distinct kinds of memory are employed for each in accordance with the requirements. GDDR3 provides far more sophisticated capabilities and requires significantly less time to operate, however it is not cheap to everyone.

DDR3 memory, on the other hand, is quite economical. As a result, it is mostly dependent on the user and what they desire or needs. GDDR5 and DDR5 memory modules have also been released to the market, bringing even more advantages and capabilities to the table.
