Samsung’s New GDDR6W Graphics Memory Doubles Performance and Capacity

Samsung announced its next-generation memory technology (opens in a new tab) for high performance graphics cards: GDDR6W. Claiming to offer twice the capacity and performance of conventional GDDR6 memory, GDDR6W would be comparable to HBM2E for absolute performance and will allow for an overall graphics memory bandwidth of 1.4TB/s. For reference, Nvidia’s beastly GeForce RTX 4090 (opens in a new tab) currently achieves 1 TB/s with GDDR6X.

Samsung sees new technology as key to enabling “immersive metaverse experiences”. (opens in a new tab) However, the new technology is unlikely to allow for more memory bandwidth or faster graphics cards in the short term. But more on that in a moment.
