Realme X
- Excellent battery endurance (86h rating)
- More affordable price point (likely)
- Reliable and consistent performance for everyday tasks
- Significantly weaker performance compared to the Poco F3 GT
- Slower charging speed (20W)
- Likely less capable camera system
Xiaomi Poco F3 GT
- Powerful Mediatek Dimensity 1200 chipset
- Ultra-fast 67W charging (100% in 42 min)
- Superior gaming performance
- Potentially shorter battery life compared to the Realme X
- May run hotter under sustained load
- Likely a higher price tag
Display Comparison
Both devices list a 'Contrast ratio: Infinite (nominal)', suggesting standard LCD or AMOLED panels without specific high-contrast technologies like mini-LED. However, detailed display specs like resolution, refresh rate, and peak brightness are missing. Given the Realme X's market positioning, it likely features a standard FHD+ panel. The Poco F3 GT, being geared towards gaming, likely boasts a higher refresh rate (potentially 120Hz) for smoother visuals, though this isn't confirmed. Without further data, it's difficult to definitively assess display quality beyond the nominal contrast ratio.
Camera Comparison
Both phones are listed with 'Photo / Video' capabilities, offering minimal insight. Without sensor size, aperture, or OIS details, a direct comparison is challenging. Given the Poco F3 GT’s focus on value, it likely features a more capable primary sensor than the Realme X. The presence of a dedicated Night Mode or advanced image processing algorithms on the Poco F3 GT is also probable. The Realme X likely offers a competent camera for everyday use, but won't compete with the Poco F3 GT in low-light scenarios or dynamic range.
Performance
The performance gap between these phones is substantial. The Poco F3 GT’s Mediatek Dimensity 1200 (6nm) is a significant leap over the Realme X’s Qualcomm Snapdragon 710 (10nm). The Dimensity 1200 features a more modern CPU architecture – a 1x3.0 GHz Cortex-A78 core alongside 3x2.6 GHz Cortex-A78 cores and 4x2.0 GHz Cortex-A55 cores – compared to the Snapdragon 710’s Octa-core (2x2.2 GHz Kryo 360 Gold & 6x1.7 GHz Kryo 360 Silver). The 6nm process node of the Dimensity 1200 also contributes to better thermal efficiency, allowing for sustained performance during extended gaming sessions. The Snapdragon 710, while capable, will struggle with graphically intensive titles at higher settings.
Battery Life
The Realme X boasts an endurance rating of 86 hours, indicating excellent battery life. However, the Poco F3 GT’s charging speed is a game-changer. While battery capacity isn’t specified for either device, the Poco F3 GT’s 67W wired charging (with PD3.0 and QC3 support) can fully charge the device in just 42 minutes. The Realme X’s 20W charging takes considerably longer, reaching 55% in 30 minutes. This means the Poco F3 GT can quickly top up its battery, minimizing downtime, even if its overall battery life is slightly shorter than the Realme X.
Buying Guide
Buy the Realme X if you need a reliable daily driver with excellent battery life and aren't heavily invested in demanding mobile games. It's ideal for users who value longevity and a consistent experience. Buy the Xiaomi Poco F3 GT if you prioritize gaming performance, rapid charging, and are willing to trade some battery endurance for a substantial boost in processing power. This phone is for those who want a near-flagship experience on a budget.
Frequently Asked Questions
❓ Will the Poco F3 GT's Dimensity 1200 overheat during prolonged gaming sessions?
While the Dimensity 1200 is a powerful chip, the Poco F3 GT incorporates thermal management solutions to mitigate overheating. The 6nm process node also contributes to better efficiency. However, extended gaming at maximum settings may still result in some thermal throttling, but it should remain playable.
❓ How much faster is the 67W charging on the Poco F3 GT compared to the Realme X's 20W charging in real-world use?
The 67W charging on the Poco F3 GT is significantly faster. While the Realme X reaches 55% charge in 30 minutes, the Poco F3 GT can achieve a full 100% charge in just 42 minutes. This translates to much less downtime and quicker top-ups throughout the day.
❓ Is the Snapdragon 710 in the Realme X still capable of playing popular mobile games like PUBG or Call of Duty?
The Snapdragon 710 can run PUBG and Call of Duty, but you'll likely need to lower the graphics settings to medium or low to maintain a smooth frame rate. It won't deliver the same level of performance or visual fidelity as the Poco F3 GT's Dimensity 1200.
