The conditional GeForce RTX 5070 will allegedly receive a 192-bit bus.
Insider kopite7kimi clarified his words about the same memory configuration for video cards of the GeForce RTX 50 and RTX 40 families. It was assumed that the configurations would be the same throughout the family; according to an insider, this is wrong.
Memory configuration supposedly will be the same at least for pre-top video cards, the GeForce RTX 5070 and RTX 5080. At the same time, the top card, the GeForce RTX 5090, will supposedly have a wider memory bus than the GeForce RTX 4090.
Estimated memory buses for GeForce RTX 50 video cards
GeForce RTX 5090: 512 bits (384 bits for RTX 4090). GeForce RTX 5080: 256 bits (256 bits for RTX 4080). GeForce RTX 5070: 192 bits (192 bits for RTX 4070).
It is expected that the GeForce RTX 50 family of video cards will use GDDR7 memory operating at 32 Gbps. This means that the memory bandwidth of the GeForce RTX 5090 will be much higher than that of the GeForce RTX 4090, which is equipped with slower memory with a narrower bus.
It is expected that video cards of the GeForce RTX 50 family will be released either at the end of 2024 or in 2025.
