Videocardz said:In a technology brief, Micron has confirmed that GeForce RTX 3090 will sport memory based GDDR6X technology. Micron has supplied memory modules for GeForce graphics cards for years now, the GDDR6X partnership takes it to the next step.
NVIDIA GeForce RTX 3090 graphics card is listed on the Micron website with 12GB GDDR6X memory. Micron estimates that GeForce RTX 3090 will be able to break the 1 TB/s barrier with a bandwidth expected between 912 to 1008 GB/s. In order to achieve 1TB/s bandwidth, the graphics card would require a clock speed of 21 Gbps and a memory bus of 384-bit (21*384/8). The speed is clearly not yet set for the NVIDIA SKU, but it should be between 19 and 21 Gbps.
