FAQ
How large a model can the GeForce RTX 4090D 48GB run?
A single GeForce RTX 4090D 48GB has 48GB of GDDR6X VRAM. At 4-bit quantization and 8K context it fits a dense model of up to about 79B parameters, or about 43B at 8-bit.
Can the GeForce RTX 4090D 48GB run a 70B model?
Yes. At 4-bit with an 8K context a 70B dense model needs about 43GB, which fits in the GeForce RTX 4090D 48GB's 48GB.
What are the best LLMs to run on the GeForce RTX 4090D 48GB?
Among models released in 2026, the largest dense model that fits entirely in VRAM at 4-bit is Gemma 4 31B, at an estimated 37.7 tokens/s. Among MoE models, Qwen3.6 35B A3B is the fastest at about 151.5 tokens/s. The full list is in the table above.
How many tokens per second does the GeForce RTX 4090D 48GB get on LLMs?
Estimated from memory bandwidth at 4-bit and 8K context: 8B dense: about 125.5 tokens/s, 14B dense: about 76.3 tokens/s, 32B dense: about 35.6 tokens/s, and 70B dense: about 16.9 tokens/s. MoE models read only the active parameters for each token, so they run much faster. Real-world results are usually 70%–100% of the estimate.
What LLMs can dual GeForce RTX 4090D 48GB cards run?
With vLLM tensor parallelism at 4-bit and 32K context, two GeForce RTX 4090D 48GB cards cannot fit any model of 50B or larger released in 2026. At 4-bit with 32K context the minimum is 4 cards, which fits Qwen3.8 Flash Next and DeepSeek V4 Flash.
How much does a GeForce RTX 4090D 48GB cost?
As of Sep 29, 2026: Xianyu median $3,526 (9 listings). Figures are medians of live listings, refreshed every 6 hours.
GeForce RTX 4090D 48GB vs RTX 6000 Ada: which is better for LLMs?
The RTX 6000 Ada has 48GB of VRAM and 960 GB/s of bandwidth; the GeForce RTX 4090D 48GB has 48GB and 1,008 GB/s. For 70B dense models at 4-bit, the GeForce RTX 4090D 48GB is estimated at about 16.9 tokens/s and the RTX 6000 Ada at about 16.1 tokens/s.
