vivo X51 5G
- More affordable price point
- Balanced performance for everyday tasks
- Potentially better camera image quality (depending on sensor)
- Sleeker, more conventional design
- Significantly weaker gaming performance
- Slower charging speed
- Less future-proof chipset
Asus ROG Phone 5s
- Exceptional gaming performance with Snapdragon 888+
- Faster 65W charging
- Likely higher refresh rate display
- Optimized thermal management for sustained gaming
- Higher price tag
- Bulky design geared towards gaming
- Potentially less balanced camera performance
Display Comparison
While both phones feature capable displays, the specifics aren't provided. However, given the ROG Phone 5s's gaming focus, it likely boasts a higher refresh rate (120Hz or 144Hz) and potentially a higher peak brightness compared to the X51 5G. The ROG Phone 5s likely utilizes AMOLED technology for vibrant colors, while the X51 5G may employ a Super AMOLED panel. Bezels are expected to be minimal on both, but the ROG Phone 5s may prioritize screen real estate over a compact form factor.
Camera Comparison
Without detailed camera specs, a direct comparison is limited. However, the ROG Phone 5s, despite its gaming focus, often includes a capable camera system. The X51 5G, positioned as a more balanced device, likely prioritizes camera quality. The X51 5G may feature a larger main sensor and more sophisticated image processing algorithms. The ROG Phone 5s may lean towards a more saturated, vibrant image profile, while the X51 5G could aim for more natural color reproduction. The absence of details on OIS and lens apertures makes a definitive assessment impossible.
Performance
The performance gap is substantial. The Asus ROG Phone 5s, powered by the Qualcomm SM8350 Snapdragon 888+ 5G (5 nm), offers a significant leap in processing power over the vivo X51 5G’s Snapdragon 765G (7 nm). The 888+ features a Cortex-X1 prime core clocked at 2.99 GHz, compared to the X51’s Kryo 475 Prime at 2.4 GHz. This translates to faster app loading, smoother multitasking, and significantly improved gaming performance. The 5nm process node of the 888+ also contributes to better thermal efficiency, reducing throttling during extended gaming sessions. The ROG Phone 5s’s likely inclusion of LPDDR5 RAM further enhances performance compared to the X51’s 8GB of RAM.
Battery Life
The Asus ROG Phone 5s boasts a 65W wired charging capability, achieving 70% charge in 30 minutes and 100% in 52 minutes, a significant advantage over the vivo X51 5G’s 33W charging, which reaches 57% in 30 minutes. While battery capacity isn't specified, the ROG Phone 5s typically features a larger battery to support its power-hungry processor and gaming demands. The ROG Phone 5s also includes 10W reverse wired charging, a feature absent in the X51 5G. The faster charging speed of the ROG Phone 5s mitigates the potential impact of a larger battery, offering quicker top-ups.
Buying Guide
Buy the vivo X51 5G if you need a well-rounded 5G smartphone with a good camera, reliable performance for everyday tasks, and a more manageable price. Buy the Asus ROG Phone 5s if you prioritize uncompromising gaming performance, fast charging, and are willing to invest in a device specifically engineered for mobile gaming.
