Graphics cards use chips, which we call GPUs, which often operate on large amounts of data at the same time. So much so that special memories are needed to transmit this amount of information in a short time. For a long time, the memories we mount in RAM sockets weren’t good enough not to be a bottleneck for parts designed by NVIDIA, AMD, and recently Intel. This is why its development is linked to that of VRAM memory chips. Samsung’s latest invention could completely change the way we think about graphics cards. So let’s see what’s so special about it.
Samsung presents its GDDR6W video memory
Under the name of GDDR6Wwhere W stands for Wide, Samsung released a new type of GDDR6 RAM that we might see in future graphics cards from NVIDIA and AMD. The idea is to stack on top of each other, but without using the vias through the silicon., two GDDR6 memory chips. Which inside the package go two by two, due to the fact that it is a dual channel memory and requires a dual interface.
Thanks to the application of new manufacturing nodes, it has reached an even lower height than GDDR6, but with twice as many chips inside the package. However, this is not only a doubling of storage capacity, but Samsung will mount its GDDR6W using its FOWLP package, which allows it to have twice as many communication pins. In short:
- GDDR6W has twice the bandwidth of GDDR6, with 64 data transmission pins instead of 32.
- Twice the capacity of GDDR6.
However, it should be specified that this is not a new memory standard,
Faster than current GDDR6
GDDR6W, using a more advanced fabrication node, can achieve much higher clock speeds than current GDDR6, reaching up to 22 Gbps transfer rate per pin. Which is better than the 20 Gbps GDDR6 of AMD’s soon-to-be-available RX 7900. It is therefore very likely that we will see its use in future models of graphics cards that will be released in 2023.
