BENCHMARK REPORT
Can I Run Llama 3.3 70B Instruct on NVIDIA GeForce RTX 4070 Super?
Comprehensive technical verdict based on static weights, dynamic KV Cache (8k baseline context window), and CUDA runtime overhead.
Official Verdict
NO — CUDA OOM
Executive Hardware Compatibility Summary: Llama 3.3 70B Instruct on NVIDIA GeForce RTX 4070 Super
Authoritative verdict, memory allocation, and token generation performance:
Direct Answer: CUDA OOM — Deficit of 35.6 GBLlama 3.3 70B Instruct exceeds dedicated physical VRAM and triggers PCIe layer offloading on NVIDIA GeForce RTX 4070 Super (12GB). At standard Q4_K_M 4-bit quantization and an 8,192-token context window, total memory demand is 47.60 GB (43.00 GB weights + 2.65 GB dynamic KV cache + 1.15 GB OS & CUDA buffers). Physical VRAM is exceeded by 35.60 GB, forcing 67 transformer layers to offload across the PCIe bus to host DDR RAM. Estimated generation throughput is ~0.7 tokens/sec (~1428.6 ms per token) with prompt prefill processing reaching ~544 tok/s.

Why does your generation speed collapse to ~0.7 tok/s? Because for every single generated token, model weights across the 67 offloaded layers must be transferred across the 31.5 GB/s PCIe slot from host system RAM.

Hardware Compatibility Q&A: Llama 3.3 70B Instruct on NVIDIA GeForce RTX 4070 Super
Technical answers for memory allocation, CUDA overhead, and execution parameters.
Can NVIDIA GeForce RTX 4070 Super run Llama 3.3 70B Instruct?
CUDA OOM — Deficit of 35.6 GB. 67/80 layers will spill to CPU RAM, causing severe PCIe bandwidth throttling (est. 0.7 tok/s). At an 8k context window, total VRAM demand is 47.6 GB compared to NVIDIA GeForce RTX 4070 Super's 12 GB frame buffer.
How much VRAM does Llama 3.3 70B Instruct require?
At standard Q4_K_M quantization and 8k context, Llama 3.3 70B Instruct requires approximately 47.6 GB of VRAM. This includes 43 GB for model weights, 2.65 GB for dynamic KV cache (Grouped-Query Attention (GQA)), 0.8 GB for activation buffers, and 1.15 GB for OS display and CUDA runtime overhead.
What generation speed (tokens/sec) can I expect on NVIDIA GeForce RTX 4070 Super?
Estimated autoregressive token generation speed is ~0.7 tokens per second with a per-token latency of ~1428.6 ms, powered by 504 GB/s memory bandwidth. Prompt prefill processing reaches ~544 tok/s (TTFT ~15059 ms).
What causes CUDA Out-of-Memory (OOM) when running Llama 3.3 70B Instruct?
CUDA OOM occurs when total memory consumption exceeds NVIDIA GeForce RTX 4070 Super's 12 GB physical VRAM. While model weights stay static, the KV cache grows with every conversation token. When VRAM fills up, inference engines (like Ollama or llama.cpp) must offload remaining layers across the PCIe bus (31.5 GB/s) to host system RAM, causing generation speed to drop sharply.
How do I run Llama 3.3 70B Instruct locally on NVIDIA GeForce RTX 4070 Super?
You can run Llama 3.3 70B Instruct directly with Ollama using "ollama run llama-3-3-70b-instruct". For advanced serving with vLLM or llama.cpp, copy the ready-to-run CLI commands in the CLI Commands section above with optimal context, quantization, and GPU layer offload parameters.

Frequently Asked Questions (FAQ)
Model weights are only one part of total VRAM consumption. When you prompt a model, the KV Cache (Key-Value Cache) stores all historical tokens. At 32k or 64k context, standard GQA attention can demand an additional 4GB to 12GB of VRAM! Combined with activation buffers and OS background consumption (0.8GB on Windows), total memory spikes beyond hardware capacity.
