Can I run Falcon Mamba 7B on a Mac?

Falcon Mamba 7B requires at least 2.7 GB at IQ2_M, 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 Falcon Mamba 7B locally?

Yes — Falcon Mamba 7B can run locally on consumer hardware. At Q4_K_M quantization it needs 4.8 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Falcon Mamba 7B?

At Q4_K_M, Falcon Mamba 7B can reach ~607 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~137 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 MI300X5300 ÷ 4.8 × 0.55 = ~607 tok/s

Estimated speed at Q4_K_M (4.8 GB)

~607 tok/s
~137 tok/s
~454 tok/s
~376 tok/s

Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
