GeForce RTX 5090 with a powerful core, but one thing will not change
A well-known informant provided interesting and important information about the GeForce RTX 5090 card, and specifically the GB202 graphics core that it will use.
We already know quite a lot about the new GeForce RTX 50 graphics cards. If the current rumors are true, the GeForce RTX 5080 model will debut this year, followed by the GeForce RTX 5090. The latter is to be equipped with a very powerful GB202 core, which will still have a monolithic structure.
GeForce RTX 5090 with a monolithic core
The GeForce RTX 5090 card will probably be equipped with the GB202 core. This one, in its full glory, will offer, among others, 192 SM units. If NVIDIA maintains the Ada Lovelace series (RTX 40) specification, i.e. 128 cores for each SM, this should translate into as many as 24,567 CUDA units. For comparison, the RTX 4090 has “only” 16,384 CUDA cores.
With such a huge increase, some people began to wonder whether the GB202 core would have an MCM (multi-chip module) structure. This seemed likely, given that this type of design is already used by NVIDIA for AI chips, such as the B100 and B200. However, @kopite7kimi, well known in the industry, denied this. According to his knowledge, GeForce RTX 5090 will use a core with a monolithic structure.

In addition, GeForce RTX 5090 can be equipped with up to a 512-bit memory interface. The rumors also mention a completely new PCB structure and, therefore, a significantly refreshed cooling system, at least in the Founders Edition models.
