Display Comparison
The Realme 12 Pro+ boasts a significantly brighter display, reaching a measured peak of 802 nits. This is crucial for outdoor visibility, a clear advantage over the Oppo A3x, which lacks published brightness data. While both likely utilize AMOLED panels given their market segment, the Realme’s higher brightness suggests a more premium panel. Bezels are expected to be similar on both devices, but the Realme’s brighter screen will offer a more vibrant viewing experience. Color accuracy is unknown for both, but Realme typically calibrates its displays well.
Camera Comparison
Without detailed camera specs, analysis relies on brand tendencies. Realme typically prioritizes camera performance, often including larger sensors and advanced image processing. The Realme 12 Pro+ likely features a more sophisticated camera system than the Oppo A3x. While both may include a standard wide, ultrawide, and potentially a macro lens, the Realme’s image processing algorithms are likely to deliver more detailed and vibrant photos, especially in challenging lighting conditions. The Oppo A3x will likely offer a competent camera experience, but may not match the Realme’s capabilities.
Performance
The Realme 12 Pro+ utilizes the Qualcomm SM7435-AB Snapdragon 7s Gen 2 (4nm), while the Oppo A3x is powered by the Mediatek Dimensity 6300 (6nm). The Snapdragon 7s Gen 2, built on a smaller 4nm process, offers superior power efficiency and thermal management compared to the 6nm Dimensity 6300. While both CPUs feature octa-core architectures with similar clock speeds (2.4GHz Cortex-A78/A76), the Snapdragon’s Cortex-A78 cores are a generation newer and more efficient. This translates to better sustained performance during demanding tasks like gaming. The Realme 12 Pro+ is also likely to benefit from faster RAM (LPDDR5x is common in this tier) compared to the A3x, further enhancing responsiveness.
Battery Life
The Realme 12 Pro+ shines in battery performance, achieving an impressive 13:24h active use score. Coupled with its 67W wired charging, capable of reaching 50% charge in just 19 minutes, it offers a significantly faster and more convenient charging experience than the Oppo A3x’s 45W charging (50% in 30 minutes). While the Oppo A3x’s battery capacity is unknown, the Realme’s longer active use score suggests a combination of efficient chipset and optimized software. The faster charging of the Realme 12 Pro+ is a major advantage for users who frequently need to top up their battery.
Buying Guide
Buy the Oppo A3x if you need a reliable daily driver with a modern chipset for everyday tasks and light gaming, and prioritize a potentially lower upfront cost. Buy the Realme 12 Pro+ if you prefer a phone that can easily last a full day, charges incredibly quickly, and offers a more refined user experience with its brighter display and potentially better camera system (based on Realme's typical image processing).
Frequently Asked Questions
❓ Does the Dimensity 6300 in the Oppo A3x struggle with graphically intensive games like Genshin Impact?
While the Dimensity 6300 is a capable chipset, Genshin Impact and similar demanding titles will likely require reduced graphics settings for a smooth experience. The Snapdragon 7s Gen 2 in the Realme 12 Pro+ offers a noticeable performance advantage and can handle these games at higher settings without significant frame drops.
❓ How much faster is the 67W charging on the Realme 12 Pro+ compared to the 45W charging on the Oppo A3x in real-world use?
The Realme 12 Pro+ can reach 50% charge in 19 minutes, while the Oppo A3x takes 30 minutes. This 11-minute difference translates to a significant time saving, especially for users who frequently need to quickly top up their battery before leaving the house. Over a full charge, the difference will be even more pronounced.
❓ Is the difference in chipset efficiency between the 6nm Dimensity 6300 and the 4nm Snapdragon 7s Gen 2 noticeable in everyday use?
The difference in efficiency is most noticeable during prolonged, demanding tasks like gaming or video recording. The 4nm Snapdragon 7s Gen 2 will generate less heat and maintain higher performance levels for longer periods, reducing the risk of thermal throttling. For typical daily use, the difference may be less apparent, but the Realme 12 Pro+ will still benefit from improved power efficiency.
