What is the difference between GDDR5 and GDDR6
What are the differences between GDDR5 and GDDR6 memory? As most of you know, graphics processors are of great importance in all kinds of devices, whether you are using a smartphone, tablet or PC. In fact, in a way, it can be called the backbone of your screen or how you see things on the screen.
Graphics memory or video card RAM is a very important component that accompanies graphics processors and has a direct impact on their performance. In these articles, we examine the latest graphics memory technologies.
GDDR5 and GDDR6 memories
One of the most common and most used graphics memory is still GDDR5, but it is increasingly being replaced by the more advanced GDDR6. Graphics cards are available in multiple price options including low range, mid range and high range. The latest development in the field of graphics cards is the launch of GDDR6 chips. So what is the difference between GDDR5 and GDDR6? What is the difference between GDDR5 and GDDR6?
The following table summarizes the most important features of GDDR5 and GDDR6 memory:
| Specifications | GDDR5/5X | GDDR6 |
|---|---|---|
| Voltage | 1.5V | 1.3V |
| Transfer Speeds | 8Gbps GDDR5 and 14Gbps GDDR5X | 16Gbps GDDR6 |
| Format | FBGA190, 0.65mm pitch, 14x10mm | FBGA180, 0.75mm pitch, 14×12mm |
| I/O Configuration | x16/x32 | x8/x16 |
| Channels | 1 | 2 |
GDDR5 features
GDDR5 is undoubtedly the fastest among graphics card memories. In fact, many graphics card manufacturers, including Nvidia, benefit from this technology. AMD’s GTX 1060, GTX 1070 and RX 580 models are some of the best examples that use GDDR5 memory modules. Some features that will make it a good option is that it comes with high bandwidth memory performance. Additionally, it has low energy consumption, which is one of the most remarkable aspects that makes it an outstanding option. GDDR5 memory can deliver speeds of up to 9 Gbps.
GDDR5 has a new enhanced version: GDDR5X. This GDDR5X memory is a new evolutionary step with the ability to reach speeds of up to 14 Gbps and high bandwidth, making it an excellent option for use in high-performance graphics cards such as the GeForce GTX 1080 Ti.
GDDR6 features
The current voltage of the memory standard is 1.3 volts and is capable of delivering transfer speeds of up to 16 Gbps with supported bandwidth of up to 72 GB/s per chip. These features currently put GDDR6 memory at a level similar to GDDR5X in terms of performance, but let’s not be fooled by this, as it is a completely new standard the potential for it to continue to improve is huge, so in the next few years we will see much faster chips reaching 20 Gbps or so in a few years Let’s not be surprised if we see it reach more.
