What is GDDR; An important feature to consider when buying a graphics card is video memory or VRAM. Today, almost any graphics card you want to get uses GDDR memory. If you want to get acquainted with this type of memory, be sure to read this article to the end. Join us at Wironal.
What is GDDR?
GDDR is a type of memory. Its full name is GDDR SDRAM, which stands for Graphics Double Data Rate Synchronous Dynamic Random-Access Memory. If you have read our article about DDR5 RAMs, you will be very familiar with this term, because GDDR is also a memory designed for graphics processing.
Over the years, several different versions of GDDR memory have been developed. The first version was called DDR SGRAM or Double Data Rate Synchronous Graphics RAM, which was later renamed GDDR SDRAM.
Gradually we saw the development of more advanced versions of memory and now we have reached GDDR6 and GDD6X. Each version of the technology brought with it increased capabilities, higher clock speeds, and higher data transfer rates, which allowed the memory to store more data, process it faster and thus improve graphical performance.
Which version of gddr should we get?
Today, almost all modern graphics cards use GDDR6, while high-end models such as the RTX 3080 include GDDR6X. This type of memory has higher bandwidth and is a little less expensive.
Until recently, it was the GDDR5 that was found on graphics cards, but today you can find it on older cards and some cheaper cards. However, you can only find a GDDR5 memory if you have a limited budget and are thinking of buying an older graphics card.
Recently, GPU performance has always been more important than its VRAM type. So if you want to get an old card equipped with GDDR5, check a few benchmarks and compare your card with new models to make sure your card is worth buying.
How much vram is good to play game?
Another obvious question is how much VRAM is needed to play at all.
In this article, we will explain more about this issue, but in short, the answer to this question depends on the resolution you want to play. In general, at least 4 GB for 1080p, between 6 and 8 GB for 1440p, and at least 8 GB for 4K are required to run modern games at the highest settings.
Are there other types of vram?
GDDR is the most common type of graphics memory found on most graphics cards, but are there other types?
One type of memory that you can find in some models is called HBM or High Bandwidth Memory. HBM (or more precisely HBM2) is more commonly found in professional graphics cards today. This is because the cost of producing this type of memory is high and modern games can not take advantage of the huge HBM bandwidth.
Apart from this, there is no other type of memory and it is unlikely that we will see the production of completely new technology right now.
