Frequently Asked Questions
How much VRAM does Gemma 3 4B T1 IT need?
Gemma 3 4B T1 IT requires 3.0 GB of VRAM at Q4_K_M, or 8.4 GB at BF16. Full 131K context adds up to 4.5 GB (7.5 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 3.9B × 4.8 bits ÷ 8 = 2.3 GB
KV Cache + Overhead ≈ 0.7 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.
KV Cache + Overhead ≈ 5.2 GB (at full 131K context)
VRAM usage by quantization
What's the best quantization for Gemma 3 4B T1 IT?
For Gemma 3 4B T1 IT, Q4_K_M (3.0 GB) offers the best balance of quality and VRAM usage. Q5_K_M (3.4 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 2.3 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Gemma 3 4B T1 IT on a Mac?
Yes — Mac Mini M2 (8 GB) and 145 other Macs can run Gemma 3 4B T1 IT. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 3.0 GB of usable unified memory (RAM minus macOS overhead).
Can I run Gemma 3 4B T1 IT locally?
Yes — Gemma 3 4B T1 IT can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Gemma 3 4B T1 IT?
At Q4_K_M, Gemma 3 4B T1 IT can reach ~1611 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~220 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 ÷ 2.98 × 0.65 = ~1745 tok/s
Estimated speed at Q4_K_M (3.0 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of Gemma 3 4B T1 IT?
At Q4_K_M, the download is about 2.33 GB. The full-precision BF16 version is 7.76 GB. The smallest option (Q2_K) is 1.65 GB.
