The vivo Y77 (China) and OnePlus Ace 2V represent compelling options in the increasingly competitive mid-range smartphone market. While both leverage Mediatek's Dimensity series, they target slightly different priorities. The Y77 focuses on delivering a solid experience at a more accessible price point, while the Ace 2V aims for near-flagship performance without the flagship price tag. This comparison dissects the key differences to help you determine which device best suits your needs.
🏆 Quick Verdict
For most users, the OnePlus Ace 2V is the superior choice. Its Dimensity 9000 chipset, built on a more efficient 4nm process, delivers significantly better performance and thermal management than the Y77’s Dimensity 930. While both offer 80W charging, the Ace 2V’s faster chipset justifies the price difference.

Display Comparison
Detailed display specifications are unavailable for the vivo Y77. However, given its market positioning, it likely features an LCD panel with a standard refresh rate. The OnePlus Ace 2V, while also lacking detailed display specs, benefits from the more powerful Dimensity 9000, which can drive higher resolution and refresh rate panels. The difference in chipset architecture suggests the Ace 2V is better equipped to handle demanding visual tasks. The absence of LTPO technology in either device suggests both will rely on adaptive refresh rate scaling rather than variable refresh rates for power efficiency.
Camera Comparison
Camera details for both phones are limited. However, the focus should be on the primary sensor capabilities. Without specific sensor sizes, it’s difficult to make a definitive judgment. The Ace 2V, being positioned higher, likely incorporates a more advanced image signal processor (ISP) within the Dimensity 9000, leading to better image processing, noise reduction, and dynamic range. The Y77 will likely rely on software optimization to compensate for a potentially less capable sensor. The prevalence of 2MP macro lenses on both devices suggests they are largely marketing features and offer limited practical benefit.
Performance
The core difference lies in the chipsets. The OnePlus Ace 2V’s Dimensity 9000 (4nm) boasts a Cortex-X2 prime core clocked at 3.05 GHz, alongside three Cortex-A710 performance cores and four Cortex-A510 efficiency cores. This configuration significantly outperforms the vivo Y77’s Dimensity 930 (6nm), which uses two Cortex-A78 cores and six Cortex-A55 cores. The 4nm fabrication process of the Dimensity 9000 translates to improved power efficiency and reduced thermal throttling under sustained load. This means the Ace 2V will maintain higher clock speeds for longer periods, resulting in smoother gaming and faster rendering times. The Y77’s Dimensity 930 is still a capable chip, but it’s a generation behind and lacks the raw power of its counterpart.
Battery Life
Both devices feature 80W wired charging, with the OnePlus Ace 2V claiming a full charge in 32 minutes. While battery capacity is unknown for both, the Dimensity 9000’s superior efficiency in the Ace 2V means it will likely consume less power during typical usage, potentially offsetting a smaller battery capacity. The 80W charging on both devices is a significant advantage, providing a quick top-up when needed. The Ace 2V’s faster chipset will also reduce idle power draw, further extending battery life.
Buying Guide
Buy the vivo Y77 (China) if you prioritize affordability and a balanced everyday experience. It’s a strong contender for users who primarily browse, use social media, and occasionally game. Buy the OnePlus Ace 2V if you demand smoother multitasking, faster app loading times, and a more capable gaming experience. It’s ideal for power users and mobile gamers who want flagship-level performance without breaking the bank.
Frequently Asked Questions
❓ Will the Dimensity 9000 in the OnePlus Ace 2V overheat during prolonged gaming sessions?
The Dimensity 9000’s 4nm process and improved thermal design in the Ace 2V significantly mitigate overheating. While some throttling is inevitable, it will be less pronounced than on the vivo Y77’s Dimensity 930, allowing for longer, more consistent gaming performance.
❓ Is the 80W charging on both phones equally effective, or does one charge faster?
The OnePlus Ace 2V explicitly states a 0-100% charge time of 32 minutes with its 80W charging. While the Y77 also supports 80W, its less efficient chipset may result in a slightly longer charging time. The Ace 2V’s charging is demonstrably faster.
❓ How much of a performance difference will I notice between the Dimensity 930 and Dimensity 9000 in everyday tasks like browsing and social media?
For basic tasks, the difference will be minimal. Both chips are capable of handling everyday usage smoothly. However, you’ll notice a significant difference when multitasking, opening demanding apps, or switching between them. The Dimensity 9000’s superior processing power will result in a snappier and more responsive experience.
