ZTE nubia Z40S Pro

  • Superior chipset (Snapdragon 8+ Gen 1) for sustained performance
  • Significantly faster charging options (up to 120W)
  • Potential for better thermal management

  • Camera specifications currently unknown
  • Display details lacking for direct comparison

Realme GT2 Pro

  • Well-documented camera performance
  • Respectable peak display brightness (778 nits)
  • Solid overall performance with Snapdragon 8 Gen 1

  • Snapdragon 8 Gen 1 prone to thermal throttling
  • Slower charging speed (65W)

Display Comparison

The Realme GT2 Pro boasts a measured peak brightness of 778 nits, a respectable figure, but the nubia Z40S Pro’s display specifications are currently unavailable for direct comparison. However, nubia often prioritizes high refresh rates and color accuracy. The GT2 Pro’s ‘Infinite’ contrast ratio is a marketing term; both phones likely utilize OLED panels with excellent contrast. Without detailed nubia Z40S Pro display specs, it’s difficult to definitively declare a winner, but the GT2 Pro’s brightness is a known quantity.

Camera Comparison

Both devices feature capable camera systems, but detailed sensor information beyond 'Photo / Video' is lacking for the nubia Z40S Pro. The Realme GT2 Pro’s camera performance is well-documented, offering strong image quality in various conditions. Without knowing the main sensor size, aperture, and OIS implementation on the Z40S Pro, it’s impossible to make a definitive camera comparison. We can assume both phones will offer a range of shooting modes, but the GT2 Pro’s established performance gives it a temporary lead until the Z40S Pro’s camera specs are revealed. Ignoring the ubiquitous 2MP macro lenses found on both devices, the primary sensor capabilities will be the deciding factor.

Performance

The nubia Z40S Pro’s Snapdragon 8+ Gen 1 (4nm) represents a significant architectural improvement over the Realme GT2 Pro’s Snapdragon 8 Gen 1 (4nm). The ‘+’ variant features a higher clocked Cortex-X2 prime core (3.19 GHz vs 3.00 GHz) and optimized efficiency. This translates to better sustained performance under load, meaning less throttling during prolonged gaming sessions. While both utilize the same LPDDR5 RAM architecture, the 8+ Gen 1’s improved thermal profile gives the nubia Z40S Pro a clear advantage for power users and gamers. The GT2 Pro’s chipset, while still powerful, is more prone to thermal throttling.

Battery Life

Both phones achieve an endurance rating of 117 hours, suggesting similar overall battery life despite potentially different battery capacities. However, the charging speeds are drastically different. The nubia Z40S Pro offers 80W wired charging (standard version) or a blistering 120W wired charging (special version), alongside 15W magnetic wireless charging. The Realme GT2 Pro is limited to 65W wired charging, taking 33 minutes to reach 100%. This difference in charging speed is substantial; the Z40S Pro can top up significantly faster, minimizing downtime. The faster charging of the Z40S Pro effectively mitigates any potential battery capacity disadvantage.

Buying Guide

Buy the ZTE nubia Z40S Pro if you prioritize sustained gaming performance, ultra-fast charging, and a phone that can handle demanding tasks without significant throttling. Buy the Realme GT2 Pro if you value a slightly more balanced approach, potentially prefer its design aesthetic, and are less concerned with pushing the absolute limits of performance for extended periods.

Frequently Asked Questions

❓ Does the Snapdragon 8+ Gen 1 in the nubia Z40S Pro actually prevent noticeable throttling during extended gaming sessions compared to the GT2 Pro?
Yes, the Snapdragon 8+ Gen 1’s improved 4nm process and architectural optimizations result in significantly better thermal efficiency. This means the Z40S Pro can maintain peak performance for longer periods without experiencing the same level of throttling as the GT2 Pro’s Snapdragon 8 Gen 1, leading to smoother gameplay and more consistent frame rates.
❓ How much faster is the 120W charging on the nubia Z40S Pro compared to the 65W charging on the Realme GT2 Pro in real-world usage?
While the Realme GT2 Pro reaches 100% in 33 minutes, the nubia Z40S Pro with 120W charging can potentially achieve a full charge in under 20 minutes. More importantly, even a short 10-15 minute charge on the Z40S Pro can provide a substantial amount of battery life, making it ideal for users who need a quick power boost.
❓ Is the magnetic wireless charging on the nubia Z40S Pro a practical feature, or is it significantly slower than wired charging?
The 15W magnetic wireless charging on the Z40S Pro is considerably slower than its 80W or 120W wired charging. However, it offers a convenient top-up option for overnight charging or when wired charging isn't readily available. It's a useful addition, but not a replacement for the speed of wired charging.
