Frequently Asked Questions
- How much VRAM does Cyber Risk Llama 3 8B need?
Cyber Risk Llama 3 8B requires 16.6 GB of VRAM at FP16. Full 8K context adds up to 0.8 GB (17.4 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 8B × 16 bits ÷ 8 = 16 GB
KV Cache + Overhead ≈ 0.6 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 1.4 GB (at full 8K context)
VRAM usage by quantization
FP1616.6 GBFP16 + full context17.4 GB- Can I run Cyber Risk Llama 3 8B on a Mac?
Cyber Risk Llama 3 8B requires at least 16.6 GB at FP16, 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 Cyber Risk Llama 3 8B locally?
Yes — Cyber Risk Llama 3 8B can run locally on consumer hardware. At FP16 quantization it needs 16.6 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Cyber Risk Llama 3 8B?
At FP16, Cyber Risk Llama 3 8B can reach ~176 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~40 tok/s. 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 ÷ 16.6 × 0.55 = ~176 tok/s
