Can I run Llama-3.3-Nemotron-Super-49B-v1 on Nvidia GeForce RTX 4070 (12GB)?
No. Llama-3.3-Nemotron-Super-49B-v1 needs ~30.6 GB even at Q4_K_M, but Nvidia GeForce RTX 4070 (12GB) only has ~11 GB usable.
Needs ~30.6 GB even at Q4_K_M, but only ~11 GB is usable.
That figure is at a 4k context and moves about ±15% as context length changes.
The gap is about 19.6 GB: Llama-3.3-Nemotron-Super-49B-v1 needs roughly 30.6 GB at Q4_K_M and Nvidia GeForce RTX 4070 (12GB) leaves only about 11 GB usable for a model. The lightest tracked hardware that runs Llama-3.3-Nemotron-Super-49B-v1 is the Nvidia GeForce RTX 5090 (32GB) at 32 GB. See Llama-3.3-Nemotron-Super-49B-v1 on Nvidia GeForce RTX 5090 (32GB).
Too big for Nvidia GeForce RTX 4070 (12GB)'s VRAM, but you could offload some layers to system RAM and still run it at roughly ~2 tok/s, far slower than a model that fits. How this is estimated.

FAQ
Can Nvidia GeForce RTX 4070 (12GB) run Llama-3.3-Nemotron-Super-49B-v1?
No. Llama-3.3-Nemotron-Super-49B-v1 needs ~30.6 GB even at Q4_K_M, but Nvidia GeForce RTX 4070 (12GB) only has ~11 GB usable.
How much memory does Llama-3.3-Nemotron-Super-49B-v1 need?
Nvidia GeForce RTX 4070 (12GB) does not have enough memory. At Q4_K_M the weights are ~28.14 GB; with KV cache and runtime overhead, budget ~30.6 GB at a 4k context.
What is the best tool to run Llama-3.3-Nemotron-Super-49B-v1 on Windows?
LM Studio for a simple setup; Ollama (CUDA) for the most speed. AMD GPUs run via Vulkan/ROCm at roughly half CUDA throughput. NVIDIA is the smooth path on Windows.

Weights are measured from GGUF files; KV cache and overhead are computed, so totals can vary ~15% with context and runtime. Any tok/s is a bandwidth estimate. See methodology.
