Frequently Asked Questions
How much VRAM does Nemotron Terminal 14B need?
Nemotron Terminal 14B requires 9.5 GB of VRAM at Q4_K_M, or 30.2 GB at BF16. Full 41K context adds up to 6.4 GB (15.9 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 14.8B × 4.8 bits ÷ 8 = 8.9 GB
KV Cache + Overhead ≈ 0.6 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 ≈ 7 GB (at full 41K context)
VRAM usage by quantization
Can NVIDIA GeForce RTX 4090 run Nemotron Terminal 14B?
Yes, at Q8_0 (15.4 GB) or lower. Higher quantizations like BF16 (30.2 GB) exceed the NVIDIA GeForce RTX 4090's 24 GB.
What's the best quantization for Nemotron Terminal 14B?
For Nemotron Terminal 14B, Q4_K_M (9.5 GB) offers the best balance of quality and VRAM usage. Q5_K_M (11.2 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 6.9 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Nemotron Terminal 14B on a Mac?
Yes — Mac Mini M2 Pro (16 GB) and 133 other Macs can run Nemotron Terminal 14B. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 9.5 GB of usable unified memory (RAM minus macOS overhead).
Can I run Nemotron Terminal 14B locally?
Yes — Nemotron Terminal 14B can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Nemotron Terminal 14B?
At Q4_K_M, Nemotron Terminal 14B can reach ~505 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~69 tok/s. 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 ÷ 9.5 × 0.65 = ~547 tok/s
Estimated speed at Q4_K_M (9.5 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of Nemotron Terminal 14B?
At Q4_K_M, the download is about 8.86 GB. The full-precision BF16 version is 29.54 GB. The smallest option (Q2_K) is 6.28 GB.
Which GPUs can run Nemotron Terminal 14B?
40 consumer GPUs can run Nemotron Terminal 14B at Q4_K_M. Top options include AMD Radeon RX 6800, AMD Radeon RX 6800 XT, AMD Radeon RX 6900 XT, AMD Radeon RX 6700 XT. 26 GPUs have plenty of headroom for comfortable inference.
Which devices can run Nemotron Terminal 14B?
150 devices with unified memory can run Nemotron Terminal 14B at Q4_K_M (9.5 GB), including AMD Ryzen AI 9 HX 370 (Strix Point) Laptop, ASUS Ascent GX10, Beelink GTR9 Pro (Ryzen AI Max+ 395, 128 GB), Framework Desktop (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.
