VRAM, also known as graphics memory, is one of the most important parts that make up today’s graphics solutions. This component is used store data and items that the GPU needs so that we can work efficiently and without it, it could not work as we all know it. Its evolution is the key to face new challenges, and Samsung showed us the short-term future with a performance GDDR6W memory.

This new type of memory is the South Korean company’s answer to the challenges posed by virtual reality and metaversion. To create a detailed world in a virtual environment and reproduce it in real time, you need huge amount of graphics memoryand also high computing capacity. With this in mind, it’s easy to understand the role played by GDDR6W memory, an important innovation that allows doubling the capacity and increasing performance, and which is based on the encapsulation technology “Fan-Out Wafer-Level Packaging”, also known as FOWLP.

The attached image shows us the distribution that GDDR6W memory uses and perfectly illustrates the differences it presents compared to traditional GDDR6 memory. As we can see, we have a stack that allows us to increase the chip density from two to four, and we also have a reduction in height and footprint. This new type of memory allows 36% thinner configuration, and despite his multi-layer design offers the same thermal characteristics as GDDR6 memory.

With GDDR6W memory, it is possible to create configurations with a bandwidth of up to 1.4 TB/s its maximum speed is 22 GHz (22 Gbps). Considering that the Micron-developed GDDR6X memory used by the GeForce RTX 4090 and GeForce RTX 4080 it already works at 21 GHz we can clarify that what is really interesting about this new type of memory from Samsung lies in the encapsulation technology it uses and the fact that twice the total capacity.

In theory, GDDR6W memory reduces the amount of I/O (input and output) to about one-eighth compared to HBM2E memory, eliminating the need to use “microbumps” (microgaps) and also Eliminates the need for a middle layer. Production of this new type of graphics memory will begin in the coming months, and it could certainly have a significant impact on next-generation graphics cards.
