NVIDIA GRAPHICS CHIPS CONTAIN UP TO 40 TINY PROCESSORS FOR HOUSEKEEPING

Summary from the TLDR Hardware newsletter

The shader cores that do actual graphics work aren't where the RISC-V lives - it's in a collective of small management processors handling clocking, memory, security, and other housekeeping, with Nvidia VP Frans Sijstermans confirming each GPU packs 10 to 40 of them depending on the model. Users can't program these cores directly, and they're cryptographically locked down so tightly the GPU firmware won't even boot if they've been tampered with.
