NVIDIA RTX 4070

The NVIDIA RTX 4070 has 12 GB VRAM and 504 GB/s memory bandwidth. It can run 28 of our 70 tracked models natively in VRAM at 8k context.

With 12 GB GDDR6X, the NVIDIA RTX 4070 is a consumer-tier GPU that can run 28 models natively. It handles 13B-class models comfortably.

NVIDIA RTX 4070: 12GB GDDR6X at 504 GB/s — same VRAM as Ti but lower clocks.

Same model compatibility as 4070 Ti with ~10-15% lower tokens/sec.

Full CUDA support. Value 12GB option.

Frequently asked questions

How much VRAM does the NVIDIA RTX 4070 have?
The NVIDIA RTX 4070 has 12 GB of GDDR6X with 504 GB/s memory bandwidth.
What is the NVIDIA RTX 4070 best for?
With 12 GB of VRAM, the NVIDIA RTX 4070 is best for running compact models (1B–8B) at low quantization, suitable for edge inference, prototyping, and lightweight tasks.
What LLMs can the NVIDIA RTX 4070 run locally?
The NVIDIA RTX 4070 can run 28 of the 70 open-weight models tracked by CanItRun natively in VRAM at 8k context. Top options include: Llama 3.1 8B Instruct at NVFP4, Llama 3.2 3B Instruct at BF16, Llama 3.2 1B Instruct at FP32.
Can the NVIDIA RTX 4070 run Llama 3.3 70B Instruct?
The NVIDIA RTX 4070 can run Llama 3.3 70B Instruct with CPU offload at Q3_K_M quantization, but inference will be slower than native VRAM execution.
Can the NVIDIA RTX 4070 run Qwen 3.6 27B?
The NVIDIA RTX 4070 can run Qwen 3.6 27B with CPU offload at NVFP4 quantization, but inference will be slower than native VRAM execution.
Can the NVIDIA RTX 4070 run Llama 3.1 8B Instruct?
Yes. The NVIDIA RTX 4070 runs Llama 3.1 8B Instruct natively in VRAM at NVFP4 quantization, achieving approximately 126 tokens per second.
