The NVIDIA GeForce RTX 4090D is a China-specific variant of the RTX 4090, released in late 2023 to comply with updated US export control regulations. It features 14,592 CUDA cores versus 16,384 on the standard RTX 4090, representing approximately an 11% reduction in shader compute throughput. Memory configuration remains unchanged at 24GB GDDR6X with 1,008 GB/s bandwidth, preserving the full memory subsystem of the standard RTX 4090. The reduction was implemented specifically to bring the chip's performance metrics below the regulatory threshold defined in the October 2023 export rule updates. The RTX 4090D is functionally a high-performance consumer GPU for the Chinese market, supporting the same Ada Lovelace features including 4th-generation Tensor Cores, 3rd-generation RT Cores, and DLSS 3 Frame Generation. It appears in GPU rental markets serving users in China.
