Oppo's mid-range offerings are becoming increasingly competitive, but choosing between the China-market A3x and the globally available K11 requires a deep dive. Both phones target budget-conscious users, but diverge in their core processing power and charging capabilities. This comparison will dissect the key differences to help you determine which device best suits your needs.
🏆 Quick Verdict
For most users, the Oppo K11 emerges as the stronger choice. Its 100W SuperVOOC charging, capable of a full charge in just 26 minutes, significantly outperforms the A3x's 45W charging. While the Dimensity 6300 is efficient, the Snapdragon 782G offers a noticeable performance edge, particularly in demanding applications.

Display Comparison
Neither Oppo provides display specifications beyond resolution in their marketing materials. However, given the price points, both likely utilize LCD panels. The real differentiator will be color calibration and peak brightness, which are currently unknown. Bezels are expected to be similar, typical of this price bracket. Without further data, it's difficult to declare a clear winner; display quality will likely be a matter of subjective preference.
Camera Comparison
Without detailed camera specifications, a direct comparison is challenging. However, Oppo generally focuses on main sensor quality. Assuming both phones feature a similar megapixel count for their primary sensors (a reasonable assumption given the market segment), the image signal processor (ISP) within the Snapdragon 782G will likely provide better image processing, resulting in improved dynamic range and low-light performance. The A3x’s Dimensity 6300 ISP is capable, but the 782G has a proven track record. We can expect both phones to include standard auxiliary lenses, but their quality is unlikely to be a deciding factor.
Performance
The Oppo K11’s Qualcomm Snapdragon 782G represents a significant step up in processing power compared to the A3x’s MediaTek Dimensity 6300. The 782G features a prime Cortex-A78 core clocked at 2.7 GHz, alongside three additional A78 cores at 2.4 GHz, offering superior multi-core performance for tasks like video editing and demanding games. The A3x relies on two Cortex-A76 cores at 2.4 GHz and six A55 cores at 2.0 GHz. While the 6nm fabrication process is shared, the architectural advantages of the Snapdragon 782G translate to a smoother experience. The K11 is the clear choice for gamers and power users.
Battery Life
The charging speed is the most significant difference. The Oppo K11’s 100W SuperVOOC charging is a game-changer, delivering a full charge in a remarkable 26 minutes. The A3x’s 45W charging, while respectable, takes considerably longer. While battery capacity isn't specified, the K11’s faster charging mitigates the impact of a potentially smaller battery. Users who frequently find themselves needing a quick top-up will overwhelmingly benefit from the K11’s charging capabilities.
Buying Guide
Buy the Oppo A3x (China) if you prioritize power efficiency and are comfortable with the China-specific software ecosystem. Its Dimensity 6300 chipset provides solid everyday performance with good battery life. Buy the Oppo K11 if you value fast charging, a more powerful processor for gaming and multitasking, and a globally supported software experience. The K11 is the better all-rounder for users who demand more from their smartphone.
Frequently Asked Questions
❓ Will the Snapdragon 782G in the Oppo K11 handle demanding games like Genshin Impact at high settings?
Yes, the Snapdragon 782G is capable of running Genshin Impact at medium to high settings with playable frame rates. While it won't match the performance of flagship chipsets, it provides a significantly better gaming experience than the Dimensity 6300 in the A3x, especially during prolonged gaming sessions due to its more robust thermal design.
❓ Is the 100W charging on the Oppo K11 safe for the battery's long-term health?
Oppo's SuperVOOC charging technology incorporates multiple safety mechanisms to protect the battery. While fast charging generates more heat, Oppo's algorithms manage the charging process to minimize degradation. The K11's charging system is designed to prioritize battery health while delivering rapid charging speeds.
❓ Does the Oppo A3x (China) support Google Mobile Services (GMS)?
The Oppo A3x, being a China-market device, likely ships with Oppo's ColorOS based on Android, but *without* pre-installed Google Mobile Services (GMS). Users may need to sideload GMS or rely on alternative app stores, which can be a complex process.
