AMD may be able install faster GDDR6 memory in future Radeon RX7900 graphics cards based upon Navi 31 GPUs with RDNA 3 architecture. They have 20Gbps per pin. The current generation is faster than the previous generation, which was only 16 Gb/s.
Greymon55, a well-known insider, reported this data. Greymon55 claims that memory bandwidth can reach 24 Gb/s in certain cases, which is comparable to the “red” cards of the Nvidia GeForce RTX3090 Ti or models from the RTX 40. This will result in a bandwidth total of 960 Gb/s or higher. . Rumours claim that this figure could reach 7 TB/s. However, this is not confirmed.
Infinity Cache will be increased to 384MB on the new cards, instead of the current 192MB. The MCM layout will be used to build the graphics chip. This means that there will be multiple chips on one substrate. However, their specific specifications are not yet known.
Greymon55 revealed previously that AMD is developing new processors using 3D V-Cache technology
