What’s the Difference Between RTX 4090D and RTX 4090?

Q: What are the differences between RTX 4090D and RTX 4090?

The RTX 4090D is a China-market variant of the RTX 4090: both feature 24 GB GDDR6X VRAM, but public specs indicate reduced CUDA core count and memory bandwidth (≈725 GB/s vs. ≈1 TB/s for the RTX 4090). Daily inference and image generation show negligible difference; under heavy training or high-frame rendering loads, performance gap is roughly 10%–20%. Pricing (as of 2026-11-12): RTX 4090D starts at ¥1.14/hour; RTX 4090 starts at ¥1.15/hour — domestic platforms offer more RTX 4090D inventory, so renting the cheaper option suffices for most use cases.

Direct answer: The RTX 4090D is the China-market variant of the RTX 4090: same 24GB GDDR6X memory, but public data indicates reduced CUDA core count and memory bandwidth (~725GB/s vs. ~1TB/s on the 4090). Daily inference and image generation show almost no perceptible difference; under heavy training loads or high-FPS rendering, performance gaps range from 10% to 20%. Pricing (as of 2026-11-12): 4090D starts at ¥1.14/hr; 4090 starts at ¥1.15/hr—domestic platforms offer more 4090D inventory, so renting the cheaper option suffices for most use cases.

Special Edition Logic

Domestic-market models released under the same export control regime as A800/H800/H20: minor spec adjustments to comply with regulatory definitions, while maintaining full ecosystem and driver compatibility. Domestic platforms mainly offer RTX 4090D; overseas platforms mainly offer RTX 4090 — both are tracked daily on this site.

When RTX 4090 is mandatory

Suitable for throughput-sensitive batch inference, video generation, and scenarios requiring co-deployment with other RTX 4090 nodes. When price differences are small, choose the RTX 4090 directly.
