Display Comparison

The Asus ROG Phone 3 boasts a 719 nits max brightness, a respectable figure for its time, but the vivo Y400 Pro’s display specifications are currently unavailable. While the ROG Phone 3’s ‘infinite’ contrast ratio is a marketing term, it indicates a good quality AMOLED panel. The ROG Phone 3’s larger display size is geared towards immersive gaming, while the Y400 Pro’s display size remains unknown, potentially offering a more compact form factor. Without knowing the Y400 Pro’s panel technology (OLED vs LCD) and refresh rate, it’s difficult to definitively declare a winner, but the ROG Phone 3’s established brightness level provides a baseline.

Camera Comparison

Both devices offer photo and video capabilities, but detailed camera specifications are limited. Without knowing sensor sizes, apertures, or image processing algorithms, a direct comparison is challenging. The ROG Phone 3’s camera system was adequate for its time, but not a primary selling point. The Y400 Pro’s camera performance will likely depend heavily on its image processing software and sensor quality, which are currently unknown. We can assume neither phone will compete with current flagship camera systems.

Performance

The core difference lies in the chipsets: the Asus ROG Phone 3 utilizes the Qualcomm Snapdragon 865 5G+ (7nm+), while the vivo Y400 Pro features the MediaTek Dimensity 7300 (4nm). The Dimensity 7300’s 4nm process offers superior power efficiency compared to the 7nm+ Snapdragon 865, potentially leading to less thermal throttling during sustained workloads. The ROG Phone 3’s CPU configuration – 1x3.10 GHz Cortex-A77, 3x2.42 GHz Cortex-A77, and 4x1.80 GHz Cortex-A55 – is a powerful setup, but the Dimensity 7300’s Octa-core (4x2.5 GHz Cortex-A78 & 4x2.0 GHz Cortex-A55) architecture, while different, aims for comparable performance with improved efficiency. The ROG Phone 3 benefits from its dedicated gaming optimizations, but the Y400 Pro’s newer architecture should provide a competitive experience.

Battery Life

The Asus ROG Phone 3 boasts an impressive endurance rating of 120 hours, indicative of a large battery capacity and efficient power management. However, its 30W wired charging, while supporting PD3.0 and QC4, is significantly slower than the vivo Y400 Pro’s 90W wired charging, capable of reaching 50% charge in just 19 minutes. The Y400 Pro also offers 6W reverse wired charging. While the ROG Phone 3’s larger battery provides longer runtime, the Y400 Pro’s charging speed offers a vastly superior convenience factor. The ROG Phone 3’s 10W reverse wired charging is also slower.

Buying Guide

Buy the vivo Y400 Pro if you need a versatile smartphone with a modern processor, incredibly fast charging, and a balanced feature set for daily use. Buy the Asus ROG Phone 3 if you prioritize a dedicated gaming experience, long battery life, and are willing to accept slower charging speeds and an older chipset. The ROG Phone 3 is best suited for users who heavily utilize gaming-specific features and don't mind a larger, heavier device.

Frequently Asked Questions

❓ Will the Dimensity 7300 in the vivo Y400 Pro be able to handle demanding games like Genshin Impact?
The Dimensity 7300 is a capable mid-range chipset that should handle Genshin Impact at medium to high settings. While it won't match the raw power of the Snapdragon 865 in the ROG Phone 3, the 4nm process and optimized architecture should provide a smooth gaming experience, especially considering the ROG Phone 3 may experience more thermal throttling over time.
❓ How much faster is the 90W charging on the vivo Y400 Pro compared to the 30W charging on the ROG Phone 3 in real-world use?
The 90W charging on the Y400 Pro is dramatically faster. While the ROG Phone 3 takes well over an hour to fully charge, the Y400 Pro can reach 50% charge in just 19 minutes. A full charge on the Y400 Pro will likely take under 40 minutes, offering a significant convenience advantage for users who frequently need to top up their battery.
❓ Does the Asus ROG Phone 3 still receive software updates?
Software update support for the Asus ROG Phone 3 is limited. While it may have received some updates in the past, it's unlikely to receive major Android version updates or frequent security patches at this point. The vivo Y400 Pro, being a newer device, will benefit from a longer software support lifecycle.
