A tech site in China is reporting that the supply of Micron GDDR6X VRAM is currently in short supply. So much so that to meet the demand for the most popular GPU to use that memory, the GeForce RTX 4070, Nvidia may release a variant with slower, and cheaper, GDDR6 chips.
When it comes to VRAM and Nvidia's GeForce RTX 40-series, there's mostly only one choice: GDDR6X. The RTX 4070, 4080, and 4090 graphics cards, as well as all the Super variants, use high-speed memory that's exclusive to Micron. It also makes GDDR6 but so do other vendors, such as Samsung and SK Hynix, which helps keep the price down, though it's not quite as fast.
