- Significantly slower charging speed (45W)
- Dimmer display (505 nits)
Realme GT3
- Revolutionary 240W SuperDart charging
- Much brighter display (974 nits)
- Slightly better battery endurance (117h)
- CPU clock speed slightly lower than Phantom X2 Pro
- Potential for higher thermal output due to faster charging
Display Comparison
The Realme GT3 boasts a significantly brighter display, reaching a measured 974 nits compared to the Tecno Phantom X2 Pro’s 505 nits. This difference is immediately noticeable in direct sunlight, where the GT3 will remain far more legible. Both displays share an 'Infinite' (nominal) contrast ratio, suggesting deep blacks, but the GT3’s brightness advantage is a key differentiator for outdoor users. While both likely employ high refresh rate panels (not specified in the data), the brightness gap is the defining characteristic here.
Camera Comparison
Both devices are listed as having 'Photo / Video' capabilities, but lack specific details regarding sensor size, aperture, or OIS. Given the market positioning, we can infer the Realme GT3 likely prioritizes a versatile camera system, potentially with a larger main sensor. However, without concrete specifications, it’s difficult to assess the image quality differences. The absence of detail suggests neither phone is aiming to compete with dedicated camera flagships.
Performance
Both phones utilize 4nm process technology, but employ different chipsets: the Realme GT3 with the Qualcomm Snapdragon 8+ Gen 1 and the Tecno Phantom X2 Pro with the MediaTek Dimensity 9000. The Snapdragon 8+ Gen 1 features a 3.0 GHz Cortex-X2 core, slightly slower than the Dimensity 9000’s 3.05 GHz Cortex-X2. However, the Dimensity 9000 has a more complex CPU configuration with three Cortex-A710 cores at 2.85 GHz versus the GT3’s 2.5 GHz. This suggests the Dimensity 9000 may offer slightly better multi-core performance. Real-world differences will likely be minimal for most tasks, but the Dimensity 9000 may have a slight edge in sustained workloads due to its potentially more efficient core configuration.
Battery Life
The Realme GT3’s 240W charging is its headline feature, capable of reaching 50% charge in just 4 minutes and 100% in 10 minutes. This is dramatically faster than the Tecno Phantom X2 Pro’s 45W charging, which takes 20 minutes for 54% and 60 minutes for a full charge. Despite the charging speed difference, both phones achieve similar endurance ratings: 117 hours for the GT3 and 109 hours for the Phantom X2 Pro. This suggests the GT3’s faster charging effectively mitigates any potential battery drain from its power-hungry features, while the Phantom X2 Pro relies on a more conservative power profile.
Buying Guide
Buy the Tecno Phantom X2 Pro if you need a consistently powerful performer with a solid all-around feature set and don't mind a slightly slower charging experience. It's ideal for users who value sustained performance over quick bursts of power. Buy the Realme GT3 if you absolutely demand the fastest charging available, frequently find yourself needing to top up quickly, and appreciate a significantly brighter screen for outdoor visibility. It’s geared towards power users and gamers.
