When it comes to graphics cards, one important factor to consider is the type of VRAM used. HBM2 and GDDR5 are the two most common types of VRAM, but what’s the difference between them? HBM2 is faster and uses less power than GDDR5, but it’s also more expensive. GDDR5 is the more common type of VRAM, and it’s used in most graphics cards.

VRAM, or Video RAM, is a type of RAM designed specifically for use with graphics processors. VRAM is typically faster than regular RAM, and offers higher bandwidth, which is important for applications that require a lot of graphics processing, such as video games.

VRAM is an important factor to consider when choosing a graphics card, as it can impact performance. Cards with more VRAM tend to be able to handle higher resolutions and more demanding games.

HBM2: The New Standard for VRAM?

The video RAM (VRAM) is the high-speed memory used to store image data for a graphics card. The higher the capacity and speed of the VRAM, the better the graphics quality of the card. For many years, the standard VRAM was GDDR5. However, a new type of VRAM, HBM2, has been developed and is now becoming the new standard.

HBM2 is short for high-bandwidth memory 2. It is a type of RAM that is faster and has more capacity than GDDR5. HBM2 uses a new technology called stacked DRAM, which allows for more data to be stored in a smaller space. This means that HBM2 VRAM can be smaller and use less power than GDDR5 VRAM.

HBM2 is also faster than GDDR5. It has a higher data transfer rate, which means that it can handle more data per second. This is important for graphics-intensive applications, such as video games, where data is constantly being read and written to the VRAM.

There are a few disadvantages to HBM2 VRAM, however. First, it is more expensive than GDDR5 VRAM. This is because the manufacturing process is more complex and the chips are smaller. Second, HBM2 VRAM is not compatible with all graphics cards. Only the newest cards, such as the NVIDIA GeForce RTX 2080, support HBM2.

Overall, HBM2 is the new standard for VRAM. It is faster and has more capacity than GDDR5, and it is slowly becoming more affordable. If you are looking to buy a new graphics card, make sure that it supports HBM2.

GDDR5: The current standard for VRAM

In terms of video RAM, or VRAM, GDDR5 is currently the standard for high-performance graphics cards. But what is GDDR5 and how does it differ from its predecessor, GDDR4?

GDDR5 is a type of synchronous dynamic random-access memory (SDRAM), which means that it is synchronized with the graphics processing unit (GPU) and can provide high bandwidth (64-bit data bus). It is also a double data rate (DDR) memory, meaning that it can transfer data on both the rising and falling edge of the clock signal. This gives GDDR5 a significant speed advantage over GDDR4, which is only single data rate (SDRAM).

The main difference between GDDR5 and GDDR4, however, is in the way that data is stored. GDDR5 uses a technology called pseudo-open drain (POD), which allows for a higher density of data storage. This means that more data can be stored on a single chip, which results in higher performance.

GDDR5 is also more power efficient than GDDR4, due to its use of POD. This means that it can run at higher speeds with less power consumption, which is important for graphics cards that are often pushed to their limits.

Overall, GDDR5 is the superior choice for VRAM, offering higher performance, higher density, and lower power consumption.

The Pros and Cons of HBM2 and GDDR5

GDDR5 is the most common type of VRAM used in graphics cards today. It is fast and has a high capacity, making it ideal for high-end gaming and other demanding applications. However, it is also relatively expensive to produce, so graphics cards with GDDR5 tend to be more expensive than those with other types of VRAM.

HBM2 is a newer type of VRAM that offers several advantages over GDDR5. It is faster, has a higher capacity, and is more power efficient. However, it is also more expensive to produce, so graphics cards with HBM2 tend to be more expensive than those with GDDR5.

Which is better for you?

There are two main types of VRAM: HBM2 and GDDR5. Both have their own advantages and disadvantages. So, which is better for you?


HBM2 is the newer type of VRAM and is faster than GDDR5. It is also more power efficient. However, it is more expensive and is not compatible with all GPUs.


GDDR5 is the older type of VRAM and is not as fast as HBM2. It is also less power efficient. However, it is less expensive and is compatible with all GPUs.

It is clear that HBM2 offers several advantages over GDDR5 in terms of speed, capacity, and power efficiency. However, GDDR5 is still the standard for most graphics cards and will likely remain so for the foreseeable future. The main reason for this is cost. HBM2 is still relatively new and expensive, so it will take some time for it to become more widespread. In the meantime, GDDR5 will continue to be the go-to choice for budget-conscious gamers.
