  • May prioritize gaming optimization over raw processing power

Display Comparison

The nubia Z70S Ultra boasts a measured peak brightness of 1395 nits, suggesting a vibrant and easily viewable display in direct sunlight. While the iQOO 12 Pro’s display specifications aren’t provided, iQOO typically employs high-quality AMOLED panels. The key difference lies in the chipset driving the display; the Snapdragon 8 Elite’s integrated display engine may offer slightly smoother rendering, but without detailed panel specs for the iQOO, it’s difficult to quantify. Both devices likely utilize high refresh rate panels, but the nubia’s brightness advantage is a clear win for outdoor visibility.

Camera Comparison

Without detailed camera specifications, a direct comparison is limited. However, both brands are known for delivering competitive camera systems. The nubia Z70S Ultra, given its flagship positioning, likely features a high-resolution main sensor with optical image stabilization (OIS). The iQOO 12 Pro is also expected to have a similar setup. The image processing style will likely differ – nubia often leans towards a more natural look, while iQOO tends to boost saturation and contrast. The absence of information on sensor sizes and lens apertures prevents a definitive judgment.

Performance

The core of this comparison is the chipset battle. The nubia Z70S Ultra features the Qualcomm SM8750-AB Snapdragon 8 Elite (3nm) with a unique octa-core configuration: 2x4.32 GHz Oryon V2 Phoenix L cores and 6x3.53 GHz Oryon V2 Phoenix M cores. This architecture is designed for sustained peak performance. The iQOO 12 Pro, conversely, utilizes the Snapdragon 8 Gen 3 (4nm) with a more conventional octa-core setup: 1x3.3 GHz Cortex-X4, 3x3.2 GHz Cortex-A720, 2x3.0 GHz Cortex-A720, and 2x2.3 GHz Cortex-A520. While the Gen 3’s Cortex-X4 core is powerful, the 8 Elite’s Oryon cores are specifically engineered for higher clock speeds and sustained performance. The 3nm process of the 8 Elite *should* offer better thermal efficiency, but real-world throttling will depend on each phone’s cooling solution. The iQOO 12 Pro benefits from the wider software optimization available for the Snapdragon 8 Gen 3.

Battery Life

The nubia Z70S Ultra achieves an active use battery score of 12:52h, a respectable result. The iQOO 12 Pro’s battery capacity is unknown, but its charging capabilities are a significant advantage. With 120W wired charging, the iQOO 12 Pro can likely achieve a full charge in under 30 minutes, significantly faster than the nubia’s 80W charging. Furthermore, the iQOO 12 Pro adds 50W wireless charging and 10W reverse wireless charging, features absent on the nubia. The Snapdragon 8 Gen 3’s 4nm process also contributes to better power efficiency, potentially offsetting any capacity difference.

Buying Guide

Buy the ZTE nubia Z70S Ultra if you absolutely need the highest possible CPU performance for tasks like video editing or emulation, and are willing to trade off some charging speed and potentially battery life for that power. Buy the vivo iQOO 12 Pro if you prioritize a balanced experience with excellent gaming performance, incredibly fast charging (both wired and wireless), and broader software support.

Frequently Asked Questions

❓ Does the Snapdragon 8 Elite in the nubia Z70S Ultra overheat during prolonged gaming sessions?
While the Snapdragon 8 Elite’s 3nm process *should* improve thermal efficiency, sustained peak performance can still generate heat. The nubia Z70S Ultra’s cooling system will be crucial. Without independent thermal testing, it’s difficult to say definitively, but the Oryon architecture is designed to maintain higher clocks for longer, potentially leading to more heat than the Gen 3 under similar loads.
❓ How much faster is the 120W charging on the iQOO 12 Pro compared to the 80W charging on the nubia Z70S Ultra?
The iQOO 12 Pro’s 120W charging is significantly faster. Expect a full charge in approximately 30-40 minutes, whereas the nubia Z70S Ultra will likely take closer to 60-75 minutes with its 80W charging. The iQOO also offers the convenience of 50W wireless charging, a feature the nubia lacks.
❓ Is the Oryon CPU architecture in the nubia Z70S Ultra noticeably faster in everyday tasks?
For typical everyday tasks like browsing, social media, and email, the difference between the Oryon cores and the Snapdragon 8 Gen 3’s cores will be minimal. The benefits of the Oryon architecture are most apparent in demanding applications like video editing, 3D rendering, and emulation, where sustained high performance is critical.
