Frequently Asked Questions
- How much VRAM does Gemma 3 1B IT ONNX GQA need?
Gemma 3 1B IT ONNX GQA requires 1.0 GB of VRAM at Q4_K_M, or 1.4 GB at Q8_0. Full 33K context adds up to 0.9 GB (1.9 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 1B × 4.8 bits ÷ 8 = 0.6 GB
KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 1.3 GB (at full 33K context)
VRAM usage by quantization
Q4_K_M1.0 GBQ4_K_M + full context1.9 GB- What's the best quantization for Gemma 3 1B IT ONNX GQA?
For Gemma 3 1B IT ONNX GQA, Q4_K_M (1.0 GB) offers the best balance of quality and VRAM usage. Q4_K_L (1.0 GB) provides better quality if you have the VRAM. The smallest option is IQ2_XXS at 0.6 GB.

- Can I run Gemma 3 1B IT ONNX GQA on a Mac?
Gemma 3 1B IT ONNX GQA requires at least 0.6 GB at IQ2_XXS, 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 Gemma 3 1B IT ONNX GQA locally?
Yes — Gemma 3 1B IT ONNX GQA can run locally on consumer hardware. At Q4_K_M quantization it needs 1.0 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Gemma 3 1B IT ONNX GQA?
At Q4_K_M, Gemma 3 1B IT ONNX GQA can reach ~3037 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~683 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 ÷ 1.0 × 0.55 = ~3037 tok/s
