Realme GT 7T
- Incredibly fast 120W charging
- Excellent battery endurance (79:21h)
- High performance Dimensity 8400 Max chipset
- Long-lasting battery health (800 cycles)
- Display brightness and technology unspecified
- Camera specs unknown, potentially less advanced
vivo X100 Ultra
- Superior display with 1801 nits peak brightness

Display Comparison
The vivo X100 Ultra immediately distinguishes itself with a peak brightness of 1801 nits, measured directly, offering superior visibility in direct sunlight compared to the GT 7T (brightness data unavailable). While the GT 7T’s panel technology isn’t specified, the X100 Ultra’s likely utilizes LTPO technology for adaptive refresh rates, conserving battery life. The X100 Ultra’s superior brightness and potential for variable refresh rates translate to a more vibrant and efficient viewing experience.
Camera Comparison
Detailed camera specs are missing for both devices, but we can infer based on brand positioning. The X100 Ultra, being a flagship, likely features a larger main sensor and more advanced image processing capabilities. While the GT 7T may offer a capable camera system, the X100 Ultra is expected to excel in low-light photography and dynamic range. The absence of information on OIS and lens apertures prevents a more granular comparison, but the X100 Ultra’s positioning suggests a more comprehensive camera experience.
Performance
The core of the performance difference lies in the chipsets. The vivo X100 Ultra boasts the Qualcomm Snapdragon 8 Gen 3 (4nm), featuring a Cortex-X4 prime core clocked at 3.3 GHz, while the Realme GT 7T utilizes the Mediatek Dimensity 8400 Max (4nm) with a slightly different core configuration (1x3.25 GHz Cortex-A725, 3x3.0 GHz Cortex-A725, 4x2.1 GHz Cortex-A725). The Snapdragon 8 Gen 3’s architectural improvements, particularly in the Cortex-X4, provide a performance edge in demanding tasks and sustained workloads. Both utilize a 4nm process, but Qualcomm’s optimizations generally lead to better thermal management and efficiency. The X100 Ultra’s LPDDR5x RAM further contributes to faster data access and overall responsiveness.
Battery Life
The Realme GT 7T boasts impressive endurance with a reported 79:21h battery life and a remarkable 800 charge cycles, suggesting long-term battery health. However, the vivo X100 Ultra, despite a shorter active use score of 12:55h, compensates with significantly faster charging options. The GT 7T’s 120W wired charging can reach 100% in 42 minutes, while the X100 Ultra offers 80W wired, 30W wireless, and reverse charging capabilities. The X100 Ultra’s versatility in charging methods and the convenience of wireless charging provide a more flexible user experience, even if the raw endurance is lower.
Buying Guide
Buy the Realme GT 7T if you need uncompromising performance on a tighter budget and value blazing-fast 120W charging above all else. It’s ideal for gamers and power users who prioritize speed. Buy the vivo X100 Ultra if you prefer a more refined, premium experience with a superior display, versatile charging options (including wireless), and the latest Snapdragon flagship chipset for sustained performance and future-proofing.
