Architecture & Throughput Transparency: Single-user decode speed (~12 tok/s) is memory-bandwidth bound at batch size = 1 on Apple MacBook Pro M4 Pro (24GB Unified Memory) (273 GB/s). Prompt prefill / TTFT (~174 tok/s) is compute-bound and utilizes GPU Tensor cores. Actual latency varies with FlashAttention-2 and runtime engine (Ollama/vLLM/llama.cpp).
MoE Memory vs Speed Architecture: While decode throughput scales with the active parameter count (4.2B parameters streamed per token), all 26.4B parameters must be resident in VRAM so the dynamic router can route tokens to any expert layer.

FAQ & Reference

Frequently Asked Questions: Google Gemma 4 26B MoE on Apple MacBook Pro M4 Pro (24GB Unified Memory)

How much VRAM does Google Gemma 4 26B MoE need on Apple MacBook Pro M4 Pro (24GB Unified Memory)?

At standard 4-bit quantization (Q4_K_M) with 32K context, Google Gemma 4 26B MoE requires 20.23 GB of total VRAM (weights + KV cache + CUDA runtime overhead).

What inference speed will Google Gemma 4 26B MoE achieve on Apple MacBook Pro M4 Pro (24GB Unified Memory)?

Based on Apple MacBook Pro M4 Pro (24GB Unified Memory)'s 273 GB/s memory bandwidth, expected decode speed is approximately 12 tokens per second.

Can I expand context beyond 32K tokens?

Each additional 32K tokens of context requires additional KV cache memory. For longer context windows, consider 8-bit or 4-bit KV cache quantization.
