Can I run it?

Can I run gemma 4 E2B it on Apple M4 Max (40-core GPU)?

Runs great

Runs great fully in unified memory on your Apple M4 Max (40-core GPU) at BF16, 8K context, about 31–43 tok/s. Weights 8.67 GB plus 0.07 GB of KV cache — 9.13 GB of 36.0 GB usable. Up to 128K context still fits.

Assumptions

• Estimate, not a benchmark. Decode speed uses a memory-bandwidth model at 55–75% of peak.
• KV cache is FP16. Engine overhead assumes llama.cpp (0.3 GB + 1% of the weights). Ollama is closer to 0.9 GB + 3%, LM Studio closer to 1 GB + 3%.
• BF16 size is the real GGUF file size from Hugging Face.
• Unified memory uses 75% for the GPU by default, and always leaves about 5 GB for the OS.
• Speed is quoted at 8K context, not at the maximum context that still fits.
