AMD's next-generation RDNA 2 based graphics cards including the Big Navi GPU-based Radeon RX 6900 XT might feature a new technology known as Infinity Cache. The technology has been part of rumors for a while now but Videocardz states that they have received confirmation regarding the implementation of the said feature in the upcoming Radeon RX 6000 series cards.

Speculation regarding Infinity Cache began a while ago when the first specifications started to leak out for the Radeon RX 6000 series lineup. RedGamingTech speculated that AMD could introduce its new Infinity Cache technology to assist with bandwidth given the smaller bus interfaces that the RX 6000 series are expected to adopt.
