Display Comparison

Both devices are expected to feature high-refresh-rate AMOLED displays, but specific details like peak brightness and panel technology are currently unavailable for the GT7. The Ace 3 Pro, while lacking detailed display specs, benefits from OnePlus’s history of delivering color-accurate and bright displays. The key difference will likely lie in the display calibration and potentially the PWM dimming frequency, impacting eye strain for sensitive users. Without concrete GT7 display data, it's difficult to definitively declare a winner, but OnePlus’s track record is a strong indicator.

Camera Comparison

Detailed camera specifications are currently lacking for the Realme GT7. The OnePlus Ace 3 Pro’s camera system is also not fully detailed, but OnePlus typically focuses on image processing and computational photography. Without sensor size or aperture information for either device, a direct comparison is impossible. However, given the flagship positioning, both are expected to offer capable camera systems, likely with OIS on the main sensor. The image processing style will likely differentiate them – Realme often leans towards vibrant, saturated colors, while OnePlus aims for a more natural look.

Performance

The core battleground is the chipset. The Realme GT7’s Dimensity 9400+ (3nm) boasts a Cortex-X925 prime core clocked at 3.73 GHz, alongside three Cortex-X4 cores at 3.3 GHz and four Cortex-A720 cores at 2.4 GHz. This configuration aims for maximum single-core and multi-core performance. Conversely, the OnePlus Ace 3 Pro utilizes the Snapdragon 8 Gen 3 (4nm) with a Cortex-X4 prime core at 3.3 GHz, three Cortex-A720 cores at 3.2 GHz, two Cortex-A720 cores at 3.0 GHz, and two Cortex-A520 cores at 2.3 GHz. The 4nm process of the Snapdragon 8 Gen 3 generally translates to better thermal efficiency, potentially mitigating throttling under sustained load. While the GT7’s CPU clock speeds are higher, the Snapdragon’s architecture and process node suggest a more consistent performance profile. Both devices utilize LPDDR5x RAM, but the efficiency of Qualcomm’s memory controller could give the Ace 3 Pro a slight edge.

Battery Life

Both phones feature 100W wired charging, but the Ace 3 Pro provides more concrete charging data: 52% in 15 minutes and 100% in 36 minutes. The GT7 only states 100W charging with bypass charging, lacking specific timing details. Bypass charging allows charging while the phone is on, minimizing heat buildup. While battery capacity is unknown for both, the Snapdragon 8 Gen 3’s superior efficiency in the Ace 3 Pro likely translates to longer real-world battery life, even with a potentially smaller battery capacity. The faster charging time of the Ace 3 Pro is a significant advantage for users who need quick top-ups.

Buying Guide

Buy the Realme GT7 (China) if you prioritize absolute peak CPU performance and are comfortable potentially managing higher temperatures during sustained workloads. This phone is ideal for benchmark enthusiasts and users who frequently engage in demanding tasks like video editing. Buy the OnePlus Ace 3 Pro if you value a refined, balanced experience with excellent gaming performance, efficient power management, and faster charging – making it the better all-rounder for daily use and extended gaming sessions.

Frequently Asked Questions
