Performance – A20 Pro 2nm vs A19 Pro 3nm
The biggest leap is the chip. The iPhone 18 Pro Max features the A20 Pro built on TSMC’s 2nm process. The iPhone 17 Pro Max uses the A19 Pro (3nm). According to PhoneArena, the A20 Pro delivers:
- 15% faster CPU performance
- 30% better energy efficiency
In addition, the new model packs 12GB of LPDDR6 RAM, up from 8GB. As a result, multitasking and on‑device AI will feel noticeably snappier.

Camera – 200MP Variable Aperture vs 48MP Fixed
The camera system sees a major upgrade. The iPhone 18 Pro Max is rumored to feature a 200MP main sensor with a variable aperture (f/1.4 to f/2.4). This allows you to control depth of field like a DSLR. The iPhone 17 Pro Max has a fixed 48MP main lens.
Other camera differences:
| Component | iPhone 17 Pro Max | iPhone 18 Pro Max |
|---|---|---|
| Main sensor | 48MP fixed | 200MP variable (f/1.4‑f/2.4) |
| Telephoto | 12MP, 5x optical | 48MP, 6x optical |
| Ultra‑wide | 12MP | 48MP |
| Front camera | 18MP | 32MP |
Therefore, photography enthusiasts will appreciate the flexibility and detail of the new system.

Battery and Charging – Bigger Capacity, Faster Wired
The iPhone 18 Pro Max packs a 5,100mAh to 5,200mAh battery – the largest ever in an iPhone. The iPhone 17 Pro Max has roughly 4,700mAh. Charging speeds also improve:
- Wired: 45W vs 35W
- MagSafe: 25W vs 15W (with appropriate adapter)
Thus, the new model charges faster and lasts longer.
