Frequently Asked Questions

How much VRAM does Llama 3 3 Nemotron Super 49B V1 need?

Llama 3 3 Nemotron Super 49B V1 requires 32.9 GB of VRAM at Q4_K_M, or 109.7 GB at BF16.

VRAM = Weights + KV Cache + Overhead

Weights = 49.9B × 4.8 bits ÷ 8 = 29.9 GB

KV Cache + Overhead ≈ 3 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.

Can I run Llama 3 3 Nemotron Super 49B V1 on a Mac?

Yes — Mac Mini M5 Pro (24 GB) and 106 other Macs can run Llama 3 3 Nemotron Super 49B V1, the smallest at IQ2_XXS. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 32.9 GB of usable unified memory (RAM minus macOS overhead), from Mac Studio M5 Max (48 GB).

Can I run Llama 3 3 Nemotron Super 49B V1 locally?

Yes — Llama 3 3 Nemotron Super 49B V1 can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Llama 3 3 Nemotron Super 49B V1?

At Q4_K_M, Llama 3 3 Nemotron Super 49B V1 can reach ~146 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 ÷ 32.9 × 0.65 = ~158 tok/s

Estimated speed at Q4_K_M (32.9 GB)
