Frequently Asked Questions
- How much VRAM does Dorna Llama3 8B Instruct need?
Dorna Llama3 8B Instruct requires 17.6 GB of VRAM at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 8B × 16 bits ÷ 8 = 16 GB
KV Cache + Overhead ≈ 1.6 GB (at 2K context + ~0.3 GB framework)
VRAM usage by quantization
BF1617.6 GB- Can I run Dorna Llama3 8B Instruct on a Mac?
Dorna Llama3 8B Instruct requires at least 17.6 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 Dorna Llama3 8B Instruct locally?
Yes — Dorna Llama3 8B Instruct can run locally on consumer hardware. At BF16 quantization it needs 17.6 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Dorna Llama3 8B Instruct?
At BF16, Dorna Llama3 8B Instruct can reach ~166 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~37 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 ÷ 17.6 × 0.55 = ~166 tok/s
