vivo X100s
- Potentially higher peak CPU performance in multi-threaded tasks.
- Faster initial charging speed (50% in 11 minutes).
- Dimensity 9300+ may offer better thermal efficiency under sustained load.
- Lack of detailed display specifications.
- Uncertain camera performance compared to Xiaomi’s Ultra series.
Xiaomi 14 Ultra
- Brighter display (1281 nits) for better outdoor visibility.
- More balanced CPU architecture for sustained performance.
- Excellent battery life (11:25h active use).
- Wireless charging support (80W).
- Slightly slower wired charging (33 minutes to full).
- Snapdragon 8 Gen 3 can still generate heat under extreme load.
Display Comparison
The Xiaomi 14 Ultra boasts a significantly brighter display, reaching a measured 1281 nits, compared to an unstated peak brightness for the X100s. While both likely utilize LTPO technology for adaptive refresh rates, the 14 Ultra’s higher peak brightness translates to better visibility in direct sunlight. The absence of detailed display specs for the X100s (PWM rate, color gamut coverage) leaves the 14 Ultra with a clear advantage in this category, particularly for users who consume a lot of outdoor content.
Camera Comparison
Without detailed camera specifications for either device, a direct comparison is challenging. However, Xiaomi’s Ultra series is renowned for its camera prowess, and we can expect a sophisticated imaging system with advanced features. The 14 Ultra likely features a larger main sensor and more advanced image processing algorithms. While the X100s may offer competitive image quality, Xiaomi’s established track record in mobile photography gives it an edge. The absence of information regarding sensor sizes and lens apertures on the X100s makes it difficult to assess its potential.
Performance
Both devices feature the latest generation of flagship chipsets, but their architectures differ. The Xiaomi 14 Ultra’s Snapdragon 8 Gen 3 (4nm) utilizes a 1x3.3 GHz Cortex-X4 prime core, while the vivo X100s’ Dimensity 9300+ (4nm) employs a 1x3.4 GHz Cortex-X4, alongside *three* additional Cortex-X4 cores. This suggests the X100s may excel in heavily multi-threaded workloads. However, the Snapdragon 8 Gen 3’s more refined architecture and Qualcomm’s optimizations often translate to better sustained performance and thermal management. The 14 Ultra’s CPU configuration (3x3.2 GHz Cortex-A720, 2x3.0 GHz Cortex-A720, 2x2.3 GHz Cortex-A520) is more balanced, potentially avoiding the throttling issues that can sometimes plague aggressively clocked chips. The X100s' reliance on the A720 core for a larger portion of its CPU cluster could impact efficiency.
Battery Life
The Xiaomi 14 Ultra delivers an impressive 11:25h of active use, showcasing excellent battery life despite its high-performance components. The X100s offers 100W wired charging, achieving 50% charge in just 11 minutes, while the 14 Ultra’s 90W wired charging takes 33 minutes for a full charge. The 14 Ultra also supports 80W wireless charging (46 minutes to full) and 10W reverse wireless charging, offering greater versatility. While the X100s’ faster initial charging burst is appealing, the 14 Ultra’s overall battery endurance and wireless charging options provide a more complete package.
Buying Guide
Buy the vivo X100s if you prioritize raw CPU power for demanding tasks and appreciate the potential for improved thermal efficiency with the Dimensity 9300+. Buy the Xiaomi 14 Ultra if you value a consistently high-performing system, a brighter and more vibrant display, and a more mature software ecosystem with robust camera capabilities.
