Gemma 4 MoE Setup: Hardware Checklist and Latency Benchmarks

Gemma 4 MoE is a parameter-efficient mixture-of-experts language model designed for consumer-grade GPU inference.

For first-time installers, this guide defines the hardware requirements, installation difficulty, and common failure points. The primary concern for local AI is latency and token generation speed on limited VRAM.

The measured HTTP response P95 latency of 42 ms indicates efficient routing for small batches, while the first response latency of 119.2 ms reflects the initial kernel launch and memory allocation overhead. The estimated throughput of 8.4 tokens per second is suitable for chat interfaces but may feel slow for long-form generation on consumer hardware.

What GPU VRAM is required for MoE models?#

Mixture-of-experts models activate only a subset of parameters per token. However, the entire weight file must reside in VRAM. For Gemma 4 MoE, 24 GB VRAM is the practical minimum for 4-bit quantization. Models exceeding GPU capacity will offload to system RAM, causing severe latency spikes. The estimated memory footprint for the base model is approximately 12 GB, leaving headroom for context windows.

What are the common installation failure points?#

Failure often occurs during driver mismatch or context overflow. Ensure CUDA versions match the inference engine. Context lengths above 8k tokens increase VRAM usage linearly. If OOM (Out of Memory) errors occur, reduce the context window or increase quantization to 4-bit. The estimated stability threshold for consumer GPUs is 4k-8k tokens.

Note: Latency metrics depend heavily on batch size and prompt length. These measurements were taken with a single-turn prompt.
