Display Comparison
The Asus ROG Phone 3 boasts a measured peak brightness of 719 nits, providing excellent visibility even in bright outdoor conditions. While the K30 Ultra’s display specs aren’t provided, the ROG Phone 3’s infinite contrast ratio (typical of AMOLED panels) delivers deeper blacks and more vibrant colors. The ROG Phone 3’s larger display size (assumed, based on ROG Phone lineage) likely contributes to a more immersive gaming experience. The K30 Ultra’s display technology is unknown, but given its price point, it likely utilizes an LCD panel, potentially lacking the color accuracy and contrast of the ROG Phone 3’s AMOLED.
Camera Comparison
Both devices feature photo/video capabilities, but detailed camera specifications are limited. The ROG Phone 3, being a flagship, likely incorporates a more sophisticated camera system with larger sensors and advanced image processing algorithms. The K30 Ultra, while capable, likely prioritizes cost-effectiveness in its camera module. Without specific sensor size or aperture information, it’s difficult to make a definitive judgment, but the ROG Phone 3’s overall premium positioning suggests a superior camera experience.
Performance
The Asus ROG Phone 3’s Snapdragon 865 5G+ chipset, with its octa-core configuration (1x3.10 GHz Cortex-A77, 3x2.42 GHz Cortex-A77, and 4x1.80 GHz Cortex-A55), offers a performance advantage over the Redmi K30 Ultra’s Mediatek Dimensity 1000+ (4x2.6 GHz Cortex-A77 & 4x2.0 GHz Cortex-A55). The Snapdragon 865+’s higher clock speeds and more efficient core arrangement translate to smoother gameplay and faster app loading times. While the Dimensity 1000+ is a capable processor, the Snapdragon 865+ benefits from Qualcomm’s optimized gaming software and hardware acceleration. Both utilize a 7nm process, but the Snapdragon 865+ is a refined version, offering better thermal management and sustained performance.
Battery Life
Both phones share an endurance rating of 120 hours, indicating comparable battery life under typical usage. However, the ROG Phone 3’s larger battery capacity (assumed, based on ROG Phone tradition) likely contributes to longer gaming sessions. The K30 Ultra’s 33W wired charging is slightly faster than the ROG Phone 3’s 30W charging, achieving a full charge in 58 minutes. The ROG Phone 3 also offers 10W reverse wired charging, a feature absent on the K30 Ultra, allowing it to charge other devices.
Buying Guide
Buy the Xiaomi Redmi K30 Ultra if you need a powerful gaming phone without breaking the bank, prioritizing a balance of performance and affordability. You'll appreciate its fast charging and capable processor for most mobile games. Buy the Asus ROG Phone 3 if you prefer an uncompromising gaming experience, demanding the highest possible frame rates, extended battery life, and features tailored specifically for competitive gaming, and are willing to pay a premium for it.
