Can MacBook Neo A18 Pro 8GB run gemma-4-E4B-it?

Apple · 8 GB LPDDR5X · 60 GB/s bandwidth · Google · 8.0B · model ctx up to 128K

✅ Yes — MacBook Neo A18 Pro 8GB (8 GB) can run gemma-4-E4B-it at Q4 (8K)
VRAM: 5.59 GB needed of 8 GB
Speed: ~9.4 tok/s (estimated)
TT · Tight FitComposite score: VRAM headroom × 0.5 + tok/s speed × 0.5. Q4 @ 8K context.
