NVIDIA GeForce RTX 4090 D Review

If you're searching for the NVIDIA GeForce RTX 4090 D, this is the China-only export-compliant version of the RTX 4090 that NVIDIA introduced in late 2023 to comply with tightened US export rules.

It cuts CUDA cores from 16,384 down to 14,592 and lowers TDP from 450W to 425W compared to the global RTX 4090, but keeps the same 24GB of GDDR6X, so real-world gaming performance lands roughly 5-10% behind a standard RTX 4090.

Performance & Use Case

It still handles native 4K gaming with ray tracing and DLSS 3 Frame Generation at high frame rates, and its 24GB frame buffer is plenty for 3D rendering and AI workflows. It was aimed at enthusiasts and creators in mainland China who wanted the fastest GeForce card available there before the RTX 50 series launched.

Comparison to Alternatives

Against the global NVIDIA GeForce RTX 4090 (nvidia-rtx-4090), the 4090 D loses about 11% of its CUDA core count and a small amount of clock headroom, translating to a modest but measurable real-world gap in both rasterization and ray tracing benchmarks. Against the newer NVIDIA GeForce RTX 5090 D (nvidia-rtx-5090-d), which replaced it as NVIDIA's China-market flagship, the 4090 D falls well behind thanks to the jump to Blackwell architecture, GDDR7 memory, and a much larger core count.
