Display Comparison
While both phones likely feature LCD panels (data not provided), the core difference lies in the processing power driving them. The Redmi K30 Pro Zoom, benefiting from the Snapdragon 865, can handle higher refresh rates and more complex graphics rendering without strain. The iQOO Z1x’s Snapdragon 765G will be adequate for standard use, but may struggle with graphically intensive games at maximum settings. Without display specs, we can assume the K30 Pro Zoom’s chipset allows for a potentially smoother visual experience.
Camera Comparison
Without detailed camera specifications, it’s difficult to make a definitive judgment. However, the Redmi K30 Pro Zoom, positioned as a more premium device, likely incorporates a superior camera sensor and image processing pipeline. The Snapdragon 865’s ISP (Image Signal Processor) is more advanced, enabling better dynamic range, noise reduction, and overall image quality. While the iQOO Z1x will capture acceptable photos in good lighting, the K30 Pro Zoom is expected to excel in challenging conditions and offer more versatile shooting options.
Performance
The Snapdragon 865 in the Redmi K30 Pro Zoom is the dominant force here. Built on a 7nm+ process, it features a Cortex-A77 prime core clocked at 2.84 GHz, significantly exceeding the 2.4 GHz Kryo 475 Prime core of the iQOO Z1x’s Snapdragon 765G. This translates to approximately 25-30% faster CPU performance in benchmarks and a substantial improvement in GPU capabilities. The K30 Pro Zoom’s Adreno 650 GPU will deliver a far superior gaming experience compared to the Z1x’s Adreno 620. The 765G is still capable, but the 865 offers headroom for future app and game demands.
Battery Life
Both devices feature 33W wired charging, with the Redmi K30 Pro Zoom adding support for PD and QC4, potentially optimizing charging speeds with compatible chargers. Xiaomi claims a 100% charge in 63 minutes, while the iQOO Z1x’s charging time is unspecified. While battery capacity isn’t provided, the more efficient Snapdragon 865 in the K30 Pro Zoom, despite its higher performance, could potentially offset a slightly smaller battery size, resulting in comparable real-world battery life. The added charging protocols on the K30 Pro Zoom offer greater flexibility.
Buying Guide
Buy the vivo iQOO Z1x if you need a reliable 5G phone for everyday tasks, social media, and light gaming, and are on a strict budget. You'll appreciate its efficient processor and fast charging. Buy the Xiaomi Redmi K30 Pro Zoom if you prioritize demanding mobile gaming, content creation, and want a phone that will remain performant for years to come, even with intensive use. The Snapdragon 865 provides a substantial performance advantage.
Frequently Asked Questions
❓ Will the Redmi K30 Pro Zoom get noticeably hot during extended gaming sessions?
The Snapdragon 865 is a powerful chip and can generate heat under sustained load. While Xiaomi likely implemented thermal management solutions, expect some degree of warming during prolonged gaming. The iQOO Z1x, with its less powerful processor, will generally run cooler.
❓ Is the Snapdragon 765G in the iQOO Z1x sufficient for playing PUBG Mobile?
Yes, the Snapdragon 765G can run PUBG Mobile, but you may need to lower graphics settings to achieve a consistently smooth frame rate. The Redmi K30 Pro Zoom will provide a significantly better PUBG experience with higher graphics settings and more stable performance.
❓ Does the Redmi K30 Pro Zoom support Wi-Fi 6?
Given the Snapdragon 865's capabilities and the K30 Pro Zoom's positioning, it almost certainly supports Wi-Fi 6, offering faster and more reliable wireless connectivity when paired with a compatible router. The iQOO Z1x's Wi-Fi capabilities are likely limited to Wi-Fi 5.
