Now, an X user has photos of a purported 16GB version of the Intel Arc A750 graphics card. What makes the card noteworthy is that Intel settled on an 8GB GPU and never brought the 16GB card to market. The graphics card is made by Gunnir and, as its label makes clear, has both 16GB of VRAM and a 512-bit bus. The Gunnir Intel Arc B580 is available in different configurations, including a 12GB model with a 192-bit bus, for example. The Intel Arc B580 made waves when it arrived because it offered solid midrange performance for an MSRP of $250.
