HOW TO CHOOSE
RTX 4090D vs RTX 4090
The D variant loses a few percent of compute and nothing else that matters for LLM work. Rent whichever is cheaper on the panel.
Workload fit
RTX 4090: small-model inference, fine-tuning 7b-13b, image generation. RTX 4090D: llm inference to ~13b, fine-tuning.
RTX 4090 VS RTX 4090D - FAQ
Which is cheaper to rent, RTX 4090 or RTX 4090D?
By today's published on-demand rates: RTX 4090 starts at $0.090/GPU/hr (median $0.48, 38 providers) and RTX 4090D starts at $0.294/GPU/hr (median $0.31, 2 providers). The cheapest live listing is the RTX 4090 at SpotGPUs. Figures recompute from the panel on every refresh.
RTX 4090 or RTX 4090D - which should I rent?
RTX 4090: The RTX 4090 is the consumer card that built the budget GPU-cloud market: L40S-class FP16 throughput at a fraction of the price, limited by 24 GB of memory, no ECC, and no datacenter software features. RTX 4090D: The 4090D is the export-compliant variant of the RTX 4090 sold in restricted markets: slightly reduced compute, the same 24 GB of fast GDDR6X. The side-by-side spec table and live price rows above give the full picture.
