- Older 7nm+ Snapdragon 865 chipset
- Larger and heavier form factor
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.
