Display Comparison
The OnePlus 8T boasts a brighter display, reaching a measured 802 nits, compared to an unspecified brightness for the iQOO Z1x. While both likely utilize AMOLED panels (based on brand history), the 8T’s higher peak brightness translates to better visibility in direct sunlight. The 8T’s ‘Infinite’ contrast ratio (nominal) suggests excellent black levels, typical of AMOLED technology. The iQOO Z1x’s display specs are less defined, suggesting a more cost-optimized panel.
Camera Comparison
Both phones offer photo and video capabilities, but detailed sensor information is lacking for the iQOO Z1x. The OnePlus 8T likely features a more sophisticated camera system, leveraging the processing power of the Snapdragon 865 for improved image quality and features. Without specific sensor details for the Z1x, it’s difficult to make a direct comparison, but the 8T’s flagship chipset provides a clear advantage in image processing and potentially, low-light performance. We can assume the 8T has a more capable main sensor.
Performance
The core difference lies in the chipsets. The OnePlus 8T’s Snapdragon 865 (7nm+) is a significant step up from the iQOO Z1x’s Snapdragon 765G (7nm). The 865 features a more powerful CPU configuration – a 2.84 GHz Cortex-A77 prime core versus the Z1x’s 2.4 GHz Kryo 475 Prime. This, combined with the 865’s superior GPU, results in noticeably faster app loading, smoother multitasking, and a better gaming experience. The 865 also benefits from a more advanced 7nm+ fabrication process, potentially offering better thermal efficiency under sustained load. The Z1x’s 765G is still capable, but will struggle with graphically intensive tasks.
Battery Life
Both devices achieve an endurance rating of 104 hours, suggesting similar overall battery life despite the iQOO Z1x’s unspecified battery capacity. However, the charging speeds are drastically different. The OnePlus 8T’s 65W wired charging can fully charge the phone in just 39 minutes, a massive advantage over the iQOO Z1x’s 33W charging. This faster charging significantly reduces downtime and makes the 8T more convenient for users who frequently need to top up their battery.
Buying Guide
Buy the vivo iQOO Z1x if you prioritize affordability and are willing to compromise on raw processing power and charging speed. It’s ideal for everyday tasks and light gaming. Buy the OnePlus 8T if you demand smoother performance for demanding apps and games, value incredibly fast charging, and appreciate a more polished software experience. It’s the better option for power users and those who want a phone that will last longer.
