Best AI Models for NVIDIA GeForce RTX 4080 SUPER (16.0GB)

VRAM:16.0 GB GDDR6X·Bandwidth:736.0 GB/s·CUDA Cores:10,240·TDP:320W·MSRP:$999

16 GB is a comfortable mid-range tier for local AI. Most 7B–13B models run smoothly at good quantization levels, and smaller models can run at near-full precision.

This memory tier strikes a nice balance between price and capability. Popular 7B models like Llama 3 8B, Mistral 7B, and Qwen 2.5 7B all run very well at Q4_K_M quantization with fast inference and reasonable context windows. You can also fit some larger 13B models at Q3–Q4, though you'll want to keep context lengths modest. Small models like Phi 3 Mini (3.8B) practically fly at Q8 or even FP16 quality.

Runs Well

  • 7B models at Q4–Q6 quality with good speed
  • Small models (3B–4B) at Q8 or FP16
  • 9B models (Gemma 2 9B) at Q4_K_M

Challenging

  • 13B–14B models need Q3 or lower
  • 30B+ models do not fit in VRAM
  • Long context (>8K tokens) with larger models

Frequently Asked Questions

Can NVIDIA GeForce RTX 4080 SUPER run Phi 4?

Yes, the NVIDIA GeForce RTX 4080 SUPER with 16 GB can run Phi 4, Qwen1.5 14B, GPT OSS 20B, and 1440 other models. 962 models run at excellent quality, and 237 at good quality. Check the compatibility table above for the full list with VRAM usage and estimated speed.

Is NVIDIA GeForce RTX 4080 SUPER good for AI?

The NVIDIA GeForce RTX 4080 SUPER has 16 GB of GDDR6X, making it very good for running local AI models. It supports 1199 models at good quality or better. With 736.0 GB/s memory bandwidth, it delivers solid token generation speeds. This is a solid mid-range card for running 7B–14B parameter models at good quality.

How many parameters can NVIDIA GeForce RTX 4080 SUPER handle?

With 16 GB, the NVIDIA GeForce RTX 4080 SUPER supports models from 3B to 14B parameters depending on quantization level. At Q4_K_M (the recommended sweet spot), you can fit roughly 26B parameters. 7B models run at high quality (Q5/Q6), while 14B models fit comfortably at Q4.

What quantization should I use on NVIDIA GeForce RTX 4080 SUPER?

For the best balance of quality and speed on the NVIDIA GeForce RTX 4080 SUPER, start with Q4_K_M — it preserves ~85% of the original model quality while keeping VRAM usage reasonable. You can step up to Q5_K_M for 7B models to get better quality. For 14B models that just barely fit, Q4_K_M is ideal.

How fast is NVIDIA GeForce RTX 4080 SUPER for AI inference?

With 736.0 GB/s memory bandwidth, the NVIDIA GeForce RTX 4080 SUPER achieves approximately 106 tokens/sec on a 7B model at Q4_K_M — that's very fast, well above conversational speed. A 14B model runs at ~53 tok/s. Token generation speed scales inversely with model size — smaller models are significantly faster.

tok/s = (736 GB/s ÷ model GB) × efficiency

Smaller models = faster inference. Memory bandwidth is the main bottleneck for token generation speed.

Estimated speed on NVIDIA GeForce RTX 4080 SUPER

~50 tok/s
~46 tok/s
~36 tok/s

Real-world results typically within ±20%. Speed depends on quantization kernel, batch size, and software stack.

What's the best model for NVIDIA GeForce RTX 4080 SUPER?

The top-rated models for the NVIDIA GeForce RTX 4080 SUPER are Phi 4, Qwen1.5 14B, GPT OSS 20B. The best choice depends on your use case: coding assistants benefit from code-tuned models, while general chat works well with instruction-tuned models like Llama or Qwen.

What power supply and cooling does NVIDIA GeForce RTX 4080 SUPER need?

The NVIDIA GeForce RTX 4080 SUPER has a TDP of 320 W. A good rule of thumb is to provide at least double the GPU's TDP to cover the rest of the system — that means a 650 W PSU or larger. At this power level, a high-airflow case matters: aim for at least two front intake fans and one rear exhaust, with tidy cabling so hot air isn't trapped around the card. LLM inference sustains full GPU load continuously — longer and more consistently than most gaming workloads — so also make sure your CPU cooler can keep up under combined load.
