Frequently Asked Questions
How much VRAM does Nova 70B Llama 3.3 need?
Nova 70B Llama 3.3 requires 43.3 GB of VRAM at Q4_K_M, or 142.1 GB at BF16. Full 131K context adds up to 42.3 GB (85.6 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 70.6B × 4.8 bits ÷ 8 = 42.3 GB
KV Cache + Overhead ≈ 1 GB (at 2K context + ~0.3 GB framework)
Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.
KV Cache + Overhead ≈ 43.3 GB (at full 131K context)
VRAM usage by quantization
Can NVIDIA GeForce RTX 5090 run Nova 70B Llama 3.3?
Yes, at Q2_K (31.0 GB) or lower. Higher quantizations like Q3_K_M (35.4 GB) exceed the NVIDIA GeForce RTX 5090's 32 GB.
What's the best quantization for Nova 70B Llama 3.3?
For Nova 70B Llama 3.3, Q4_K_M (43.3 GB) offers the best balance of quality and VRAM usage. Q5_K_M (51.2 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 31.0 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Nova 70B Llama 3.3 on a Mac?
Yes — Mac Studio M5 Max (48 GB) and 55 other Macs can run Nova 70B Llama 3.3. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 43.3 GB of usable unified memory (RAM minus macOS overhead).
Can I run Nova 70B Llama 3.3 locally?
Yes — Nova 70B Llama 3.3 can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Nova 70B Llama 3.3?
At Q4_K_M, Nova 70B Llama 3.3 can reach ~111 tok/s on AMD Instinct MI350X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: NVIDIA B200 → 8000 ÷ 43.3 × 0.65 = ~120 tok/s
Estimated speed at Q4_K_M (43.3 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of Nova 70B Llama 3.3?
At Q4_K_M, the download is about 42.33 GB. The full-precision BF16 version is 141.11 GB. The smallest option (Q2_K) is 29.99 GB.
Which GPUs can run Nova 70B Llama 3.3?
No single consumer GPU has enough VRAM to run Nova 70B Llama 3.3 at Q4_K_M (43.3 GB). Multi-GPU or professional hardware is required.
Which devices can run Nova 70B Llama 3.3?
67 devices with unified memory can run Nova 70B Llama 3.3 at Q4_K_M (43.3 GB), including ASUS Ascent GX10, Beelink GTR9 Pro (Ryzen AI Max+ 395, 128 GB), Framework Desktop (Ryzen AI Max+ 395, 128 GB), GMKtec EVO-X2 (Ryzen AI Max+ 395, 128 GB). Apple Silicon Macs use unified memory shared between CPU and GPU, making them well-suited for local LLM inference.
