According to wccftech reports, there is news that AMD’s next-generation RDNA 2-based graphics cards, including Big Navi GPU-based Radeon RX 6900 XT, may adopt a new technology called infinite cache. According to Videocardz, the latest news they received has confirmed that the Radeon RX 6000 series supports unlimited cache technology .
Previously, RedGamingTech speculated that, given that the RX 6000 series is expected to adopt a smaller bus interface, AMD may launch its new Infinity Cache technology to assist bandwidth.
Videocardz not only received the confirmation message, but also discovered the technology’s trademark, which was registered a few days ago . AMD’s Infinity cache may help provide higher bandwidth to the GPU, and it is reported that AMD’s flagship product Radeon RX 6900 XT will be equipped with Big Navi “Navi 21” GPU, which will use a 256-bit bus interface. The card can utilize 16 Gbps memory dies to provide a total bandwidth of 512 GB/s. In contrast, the NVIDIA GA102 GPU has a die up to 19.5 Gbps on a 384-bit bus interface, which can provide a bandwidth close to 1 TB/s.
Considering the scale of AMD Big Navi GPU, 512 GB/s may not be enough, but it does save a lot of manufacturing costs. At the same time, an auxiliary cache in the form of an infinite cache can help provide higher bandwidth, thereby providing more powerful performance in high-resolution games.
IT Home learned that AMD will officially launch the Radeon RX 6000 series graphics card series on October 28.
