Frequently Asked Questions
How much VRAM does Shieldgemma 9B need?
Shieldgemma 9B requires 6.1 GB of VRAM at Q4_K_M, or 20.3 GB at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 9.2B × 4.8 bits ÷ 8 = 5.5 GB
KV Cache + Overhead ≈ 0.6 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
What's the best quantization for Shieldgemma 9B?
For Shieldgemma 9B, Q4_K_M (6.1 GB) offers the best balance of quality and VRAM usage. Q5_K_S (7.0 GB) provides better quality if you have the VRAM. The smallest option is IQ2_XXS at 2.8 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Shieldgemma 9B on a Mac?
Yes — Mac Mini M2 Pro (16 GB) and 133 other Macs can run Shieldgemma 9B. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 6.1 GB of usable unified memory (RAM minus macOS overhead).
Can I run Shieldgemma 9B locally?
Yes — Shieldgemma 9B can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Shieldgemma 9B?
At Q4_K_M, Shieldgemma 9B can reach ~787 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~107 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 ÷ 6.1000 × 0.65 = ~852 tok/s
Estimated speed at Q4_K_M (6.1 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of Shieldgemma 9B?
At Q4_K_M, the download is about 5.55 GB. The full-precision BF16 version is 18.48 GB. The smallest option (IQ2_XXS) is 2.54 GB.
Which GPUs can run Shieldgemma 9B?
52 consumer GPUs can run Shieldgemma 9B at Q4_K_M. Top options include AMD Radeon RX 6700 XT, AMD Radeon RX 6800, AMD Radeon RX 6800 XT, AMD Radeon RX 7600. 40 GPUs have plenty of headroom for comfortable inference.
Which devices can run Shieldgemma 9B?
151 devices with unified memory can run Shieldgemma 9B at Q4_K_M (6.1 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.
