Realme GT7 (China)
- Potentially higher single-core CPU performance with Dimensity 9400+
- Faster 100W wired charging
- Bypass charging for gaming
- Battery life is unknown and potentially lower than the X100 Ultra
- Camera specifications are unknown and potentially less advanced
vivo X100 Ultra
- Exceptional battery life (12:55h active use)
- Brighter display (1801 nits)
- Versatile charging options (wired, wireless, reverse)
- Slightly slower CPU clock speed compared to the Dimensity 9400+
- Wired charging is slower than the GT7
Display Comparison
The vivo X100 Ultra immediately stands out with its measured peak brightness of 1801 nits, offering superior visibility outdoors compared to the Realme GT7, whose brightness remains unspecified. While both likely employ high refresh rate panels, the X100 Ultra’s brightness advantage is a significant benefit for users frequently exposed to bright ambient light. The absence of PWM frequency data for both devices makes it difficult to assess flicker-related eye strain, but both are expected to utilize modern technologies to mitigate this issue.
Camera Comparison
The context data lacks detailed camera specifications for both devices, making a direct comparison challenging. However, vivo’s X-series is renowned for its camera prowess, suggesting the X100 Ultra will likely feature a more sophisticated camera system with advanced image processing algorithms. The absence of information regarding sensor sizes and OIS on the GT7 makes it difficult to assess its photographic capabilities. Given vivo’s track record, the X100 Ultra is expected to excel in low-light photography and video recording.
Performance
The core of the battle lies in the chipsets. The Realme GT7’s Mediatek Dimensity 9400+ (3nm) features a unique CPU configuration with a Cortex-X925 prime core clocked at 3.73 GHz, suggesting a focus on single-core performance. The vivo X100 Ultra’s Snapdragon 8 Gen 3 (4nm) employs a more conventional Cortex-X4 prime core at 3.3 GHz. While the Dimensity 9400+ boasts higher clock speeds, the 4nm process of the Snapdragon 8 Gen 3 potentially offers better thermal efficiency, reducing the likelihood of sustained throttling under heavy load. The GT7’s LPDDR5x RAM speed is not specified, but the Snapdragon 8 Gen 3’s efficiency could offset any RAM speed advantage the GT7 might have.
Battery Life
The vivo X100 Ultra’s 12:55h active use score is a compelling advantage, indicating significantly better battery life than the Realme GT7, whose battery performance is unknown. While the GT7 boasts faster 100W wired charging, the X100 Ultra offers a more versatile charging solution with 80W wired (PD, PPS, QC, UFCS), 30W wireless, and reverse charging capabilities. The GT7’s bypass charging feature is beneficial for gamers, minimizing heat buildup during extended gaming sessions, but the X100 Ultra’s overall battery endurance and charging flexibility provide a more practical benefit for everyday users.
Buying Guide
Buy the Realme GT7 (China) if you need uncompromising CPU performance for demanding tasks like video editing, emulation, or competitive mobile gaming, and prioritize the fastest possible charging speeds. Buy the vivo X100 Ultra if you prefer a more balanced flagship experience with a class-leading camera system, exceptional battery life, and a brighter, more visible display in direct sunlight.
