Kopite7kimi has confirmed that the flagship Nvidia graphics processor GB202 will be released with a 512-bit bus. Nvidia is preparing to release a new flagship GPU GB202, which, as renowned insider Kopite7kimi claims, will have a 512-bit bus. This promises to increase the video memory capacity to 32GB on the GeForce RTX 5090 due to the use of GDDR7 memory.
The new card will not follow AMD's path with MCM design and will remain true to the monolithic architecture. There have been conflicting rumors about the specifications of the next generation of Nvidia RTX 50 series graphics cards, but Kopite7kimi confirmed the initial data about the 512-bit bus, noting the differences from the previous model GeForce RTX 4090, which had a 384-bit bus. This puts the GeForce RTX 5090 on a new level of performance and capabilities.
It is also reported that the GPU GB203, which is likely to be used in the GeForce RTX 5080, may be half the size of GB202. This could lead to a significant performance gap between the xx90 and xx80 models. GeForce RTX 5090 is expected to have 192 SM (streaming multiprocessors), but the exact number of CUDA cores is currently unknown due to the planned reconsideration of the core design.
