Frequently Asked Questions
How much VRAM does Falcon3 Mamba 7B Base need?
Falcon3 Mamba 7B Base requires 16 GB of VRAM at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 7.3B × 16 bits ÷ 8 = 14.5 GB
KV Cache + Overhead ≈ 1.5 GB (at 2K context + ~0.3 GB framework)
Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.
VRAM usage by quantization
Can I run Falcon3 Mamba 7B Base on a Mac?
Yes — Mac Mini M5 Pro (24 GB) and 106 other Macs can run Falcon3 Mamba 7B Base. Apple Silicon uses unified memory, so the model shares RAM with the system. At BF16 you need at least 16 GB of usable unified memory (RAM minus macOS overhead).
Can I run Falcon3 Mamba 7B Base locally?
Yes — Falcon3 Mamba 7B Base can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Falcon3 Mamba 7B Base?
At BF16, Falcon3 Mamba 7B Base can reach ~300 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~41 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: NVIDIA B200 → 8000 ÷ 16.0 × 0.65 = ~325 tok/s
Estimated speed at BF16 (16 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of Falcon3 Mamba 7B Base?
At BF16, the download is about 14.55 GB.
Which GPUs can run Falcon3 Mamba 7B Base?
26 consumer GPUs can run Falcon3 Mamba 7B Base at BF16. Top options include AMD Radeon RX 7900 XTX, NVIDIA GeForce RTX 3090, NVIDIA GeForce RTX 3090 Ti, AMD Radeon RX 6800. 7 GPUs have plenty of headroom for comfortable inference.
Which devices can run Falcon3 Mamba 7B Base?
122 devices with unified memory can run Falcon3 Mamba 7B Base at BF16 (16 GB), including AMD Ryzen AI 9 HX 370 (Strix Point) Laptop, ASUS Ascent GX10, Beelink GTR9 Pro (Ryzen AI Max+ 395, 128 GB), Framework Desktop (Ryzen AI Max+ 395, 128 GB). Apple Silicon Macs use unified memory shared between CPU and GPU, making them well-suited for local LLM inference.
