Display Comparison
Neither device's display specifications are provided, so a direct comparison is limited. However, given their price points, we can expect both to feature LCD panels with FHD+ resolution. The absence of details like refresh rate or peak brightness suggests neither phone is aiming for display excellence. Users prioritizing vibrant colors and high refresh rates should consider alternatives.
Camera Comparison
Without detailed camera specifications, a meaningful comparison is difficult. Both phones likely feature a multi-camera setup, but the quality will heavily depend on sensor size, aperture, and image processing algorithms. It's reasonable to assume both will include a primary sensor, an ultrawide, and potentially a macro lens. Given the market segment, image quality will likely be adequate for social media sharing but won't compete with flagship devices. The absence of OIS information suggests neither phone will excel in low-light photography.
Performance
The core difference lies in the chipsets. The vivo Y78's MediaTek Dimensity 7020 (6nm) utilizes a dual-cluster configuration with 2x 2.2 GHz Cortex-A78 cores and 6x 2.0 GHz Cortex-A55 cores. The Oppo K11x, powered by the Qualcomm Snapdragon 695 5G (6nm), employs 2x 2.2 GHz Kryo 660 Gold cores and 6x 1.7 GHz Kryo 660 Silver cores. While both CPUs peak at 2.2 GHz, the Cortex-A78 architecture in the Dimensity 7020 generally offers slightly better single-core performance than the Kryo 660 Gold. However, the Snapdragon 695 benefits from Qualcomm's optimized software and modem integration, potentially leading to more consistent 5G connectivity and overall system stability. The lower clock speed of the Silver cores on the K11x may impact multi-threaded performance compared to the Y78.
Battery Life
The Oppo K11x takes a clear lead in charging speed with its 67W wired charging, capable of reaching 80% charge in just 33 minutes. The vivo Y78 is limited to 44W wired charging, meaning a significantly longer time to full charge. While battery capacity isn't specified for either device, the faster charging of the K11x mitigates the impact of a potentially smaller battery. Users who frequently need to quickly top up their phone will greatly benefit from the K11x's charging capabilities.
Buying Guide
Buy the vivo Y78 (China) if you prioritize a potentially more efficient CPU architecture for sustained workloads and are comfortable with slower charging speeds. Buy the Oppo K11x if you value faster charging, a more established Qualcomm ecosystem, and a generally more responsive user interface for common tasks. The K11x is ideal for users who frequently top up their battery throughout the day.
Frequently Asked Questions
❓ Is the Snapdragon 695 in the Oppo K11x powerful enough for demanding games like PUBG Mobile?
The Snapdragon 695 can run PUBG Mobile, but you'll likely need to lower graphics settings to achieve a consistently smooth frame rate. It's not a gaming powerhouse, but it's capable of handling less demanding titles without issue. The Dimensity 7020 in the Y78 might offer slightly better sustained performance, but both phones are best suited for casual gaming.
❓ How much faster is the 67W charging on the Oppo K11x compared to the 44W charging on the vivo Y78 in real-world usage?
The 67W charging on the K11x will significantly reduce your charging time. While a full 0-100% time isn't specified, the K11x reaching 80% in 33 minutes demonstrates a substantial advantage. The Y78's 44W charging will likely take over an hour to reach full charge, making the K11x a much more convenient option for users who need a quick power boost.
❓ Does either phone support expandable storage via microSD card?
This information is not provided in the specifications. However, given the target market, it's possible that one or both phones offer microSD card support. Checking the official product pages or user reviews is recommended to confirm.
