vivo Y400 Pro
- Significantly faster 90W charging
- More modern and efficient Dimensity 7300 chipset
- Potentially better sustained performance due to 4nm process
- Display specifications currently unknown
- Brand recognition not as strong as OnePlus
OnePlus 8T
- Proven track record and established software experience
- Good display brightness (802 nits)
- Solid battery endurance (104 hours)
- Older Snapdragon 865 chipset
- Slower 65W charging
Display Comparison
The OnePlus 8T’s display achieves a measured peak brightness of 802 nits, providing good visibility outdoors. However, the vivo Y400 Pro’s display specifications are currently unavailable, making a direct brightness comparison difficult. Given the Y400 Pro’s positioning, it’s likely to offer a comparable, if not slightly lower, peak brightness. Both devices feature an 'infinite' contrast ratio, typical of AMOLED panels, but without knowing the Y400 Pro’s panel technology (LTPO or not), it’s hard to assess potential power savings. The 8T’s established display quality is a known quantity, while the Y400 Pro remains an unknown.
Camera Comparison
Both devices offer photo and video capabilities, but detailed camera specifications are limited. Without knowing sensor sizes, apertures, or image processing algorithms, a direct comparison is challenging. The OnePlus 8T’s camera system is known to be capable, but the Y400 Pro’s potential is unknown. It’s crucial to note that the presence of a 'photo/video' feature on both phones is insufficient for a meaningful comparison; sensor size and image processing are key differentiators. We can assume both phones will include standard features like HDR and night mode, but the quality of these implementations will vary.
Performance
The vivo Y400 Pro’s Mediatek Dimensity 7300 (4nm) represents a significant architectural leap over the OnePlus 8T’s Snapdragon 865 (7nm+). The Dimensity 7300 utilizes newer Cortex-A78 cores clocked at 2.5 GHz, alongside more efficient Cortex-A55 cores, compared to the 8T’s mix of A77 and A55 cores. While the Snapdragon 865’s prime core is clocked higher at 2.84 GHz, the Dimensity 7300’s more modern architecture and smaller process node generally translate to better sustained performance and thermal efficiency. This means the Y400 Pro is less likely to throttle under prolonged load, benefiting gamers and power users. The Y400 Pro’s 4nm process also contributes to improved battery life.
Battery Life
The OnePlus 8T boasts an endurance rating of 104 hours, a testament to its efficient power management. The vivo Y400 Pro’s battery capacity is unknown, but its 90W wired charging significantly outperforms the 8T’s 65W charging. The Y400 Pro can reach 50% charge in just 19 minutes, while the 8T requires 39 minutes for a full charge. This difference in charging speed is a major advantage for the Y400 Pro, especially for users who frequently need to top up their battery. Even if the Y400 Pro has a slightly smaller battery capacity, the faster charging could offset this difference in real-world usage.
Buying Guide
Buy the vivo Y400 Pro if you prioritize fast charging, a modern processor for efficient multitasking and gaming, and are looking for a phone that feels current. Buy the OnePlus 8T if you value a well-established brand with a known software experience, and are comfortable with a slightly older chipset and slower charging speeds, potentially at a lower price point.
