Can I run Meta Llama 3 70B on a Mac?

Meta Llama 3 70B requires at least 33.0 GB at Q2_K, 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 Meta Llama 3 70B locally?

Yes — Meta Llama 3 70B can run locally on consumer hardware. At Q4_K_M quantization it needs 46.6 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Meta Llama 3 70B?

At Q4_K_M, Meta Llama 3 70B can reach ~95 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 B2008000 ÷ 46.6 × 0.65 = ~112 tok/s
