Frequently Asked Questions
- How much VRAM does Moonlight 16B A3B Instruct GGUF need?
Moonlight 16B A3B Instruct GGUF requires 35.2 GB of VRAM at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 16B × 16 bits ÷ 8 = 32 GB
KV Cache + Overhead ≈ 3.2 GB (at 2K context + ~0.3 GB framework)
VRAM usage by quantization
BF1635.2 GB- Can NVIDIA GeForce RTX 5090 run Moonlight 16B A3B Instruct GGUF?
No — Moonlight 16B A3B Instruct GGUF requires at least 35.2 GB at BF16, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.
- Can I run Moonlight 16B A3B Instruct GGUF on a Mac?
Moonlight 16B A3B Instruct GGUF requires at least 35.2 GB at BF16, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.
- Can I run Moonlight 16B A3B Instruct GGUF locally?
Yes — Moonlight 16B A3B Instruct GGUF can run locally on consumer hardware. At BF16 quantization it needs 35.2 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Moonlight 16B A3B Instruct GGUF?
At BF16, Moonlight 16B A3B Instruct GGUF can reach ~83 tok/s on AMD Instinct MI300X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: AMD Instinct MI300X → 5300 ÷ 35.2 × 0.55 = ~83 tok/s
Estimated speed at BF16 (35.2 GB)
AMD Instinct MI300X~83 tok/sNVIDIA H100 SXM~62 tok/sAMD Instinct MI250X~51 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
