Display Comparison
Neither Oppo nor vivo provide display specifications beyond the basic existence of a display. Assuming both utilize IPS LCD panels common in this price bracket, the display experience will likely be similar. Color accuracy and peak brightness will be key differentiators, but without data, we can only speculate. Bezels are likely comparable, focusing on maximizing screen real estate within the budget constraints.
Camera Comparison
Camera details are absent, making a direct comparison difficult. However, given the price point, both phones likely feature a primary sensor paired with depth or macro lenses. Without megapixel counts or aperture information, it's impossible to assess image quality. Image processing will be a key differentiator, with Oppo and vivo employing different algorithms for color science and dynamic range. The absence of OIS on either device suggests reliance on software stabilization.
Performance
The core difference lies in the chipsets. The Oppo A3x (China) features the Mediatek Dimensity 6300, built on a 6nm process, with an octa-core configuration peaking at 2.4 GHz Cortex-A76 cores. This architecture generally offers better single-core performance than the Qualcomm Snapdragon 695 in the vivo Y78+. The Snapdragon 695, also 6nm, utilizes 2x2.2 GHz Kryo 660 Gold cores. While both are 6nm, the Cortex-A76 cores in the Dimensity 6300 are a generation newer and more efficient. This translates to snappier app launches and smoother multitasking on the Oppo. The Dimensity 6300's GPU will also likely provide a more capable gaming experience. RAM speed (LPDDR4X vs LPDDR5) is unknown, but would further impact performance.
Battery Life
Battery capacity is not specified for either device. However, the charging speeds are known: 45W wired for the Oppo A3x (China) with PD support, and 44W for the vivo Y78+. The slight advantage in charging wattage for the Oppo suggests a potentially faster 0-100% charge time, especially with PD support enabling optimized charging profiles. Real-world battery life will depend heavily on the battery capacity, but the more efficient Dimensity 6300 in the Oppo A3x could contribute to longer runtimes.
Buying Guide
Buy the Oppo A3x (China) if you need a phone that can handle multitasking and moderate gaming with a bit more headroom. Its Dimensity 6300 provides a noticeable performance boost. Buy the vivo Y78+ if you prioritize a well-rounded experience with a focus on reliable performance for everyday tasks and a potentially more refined software experience, given vivo's established software optimization.
Frequently Asked Questions
❓ Will the Snapdragon 695 in the vivo Y78+ struggle with graphically intensive games like PUBG Mobile?
The Snapdragon 695 is capable of running PUBG Mobile, but you'll likely need to lower the graphics settings to achieve a consistently smooth frame rate. The Dimensity 6300 in the Oppo A3x (China) will offer a more comfortable gaming experience at higher settings due to its more powerful GPU.
❓ Does the Oppo A3x (China) support widevine L1 for HD streaming on platforms like Netflix and Amazon Prime Video?
This information is not readily available. However, Oppo typically includes Widevine L1 support in their devices, even in the mid-range segment. It's advisable to check user reports or official specifications after purchase to confirm HD streaming compatibility.
❓ How does the software experience differ between Oppo's ColorOS and vivo's Funtouch OS?
ColorOS and Funtouch OS are both based on Android, but offer distinct user interfaces and features. Funtouch OS has historically been criticized for being heavily customized, but recent iterations have become more refined. ColorOS is known for its customization options and feature-richness. The preferred experience is subjective, but vivo generally focuses on a cleaner, more streamlined approach.
