Display Comparison
Neither device boasts a standout display. While specific display specs (resolution, panel type) are absent, the focus here is on the underlying processing power impacting UI smoothness. The chipset differences will be more noticeable in scrolling and app loading than any minor display variations.
Camera Comparison
Without detailed camera specifications, a direct comparison is limited. However, both phones likely feature similar budget-oriented camera setups. The image signal processor (ISP) within the Dimensity 700 may offer slightly better image processing capabilities, potentially resulting in improved dynamic range and noise reduction. The absence of optical image stabilization (OIS) on either device suggests reliance on software stabilization, where the Dimensity 700’s ISP could again provide an edge.
Performance
The core difference lies in the chipsets. The vivo Y75 5G’s Mediatek Dimensity 700, fabricated on a 7nm process, offers a significant architectural advantage over the Oppo A77 4G’s Mediatek Helio G35 (12nm). The Dimensity 700 utilizes Cortex-A76 performance cores alongside A55 efficiency cores, providing a noticeable boost in CPU performance (2.2GHz vs 2.3GHz peak, but with superior core architecture). This translates to faster app launches, smoother multitasking, and improved performance in demanding applications. While the Helio G35’s Cortex-A53 cores are power-efficient, they lack the performance headroom of the Dimensity 700. The 7nm process also contributes to better thermal efficiency in the Y75 5G, potentially reducing throttling during sustained workloads.
Battery Life
The Oppo A77 4G’s 33W wired charging is a clear advantage over the vivo Y75 5G’s 18W charging. This translates to a significantly faster 0-100% charge time (69 minutes for the A77 4G). While battery capacity isn’t specified, the more efficient Dimensity 700 in the Y75 5G might offset a slightly smaller battery, but the A77 4G will likely offer quicker top-ups when needed.
Buying Guide
Buy the Oppo A77 4G if you prioritize faster charging speeds (33W) and are content with 4G connectivity, focusing on everyday tasks and casual gaming. Buy the vivo Y75 5G if you want access to 5G networks for faster data speeds and are willing to trade off charging speed (18W) for that connectivity and a more modern chipset architecture.
Frequently Asked Questions
❓ Will the vivo Y75 5G actually get significantly faster download speeds in my area?
5G speeds are heavily dependent on network availability and your carrier. While the Y75 5G supports 5G, you'll only experience faster speeds if you're in an area with 5G coverage and have a 5G data plan. Check your carrier's coverage map to determine 5G availability in your location.
❓ Is the Mediatek Helio G35 in the Oppo A77 4G powerful enough for playing games like PUBG Mobile?
The Helio G35 can run PUBG Mobile, but you'll likely need to lower the graphics settings to achieve a smooth frame rate. The Dimensity 700 in the Y75 5G will provide a noticeably better gaming experience with higher settings and more consistent performance.
❓ How much of a difference will the charging speed make in daily use?
The 33W charging on the Oppo A77 4G is a substantial advantage. A quick 30-minute charge can add a significant amount of battery life, making it ideal for users who frequently need to top up their phone throughout the day. The 18W charging on the Y75 5G will take considerably longer to achieve the same level of charge.
