Display Comparison

The BLU C7’s display specifications are not provided, so we can assume it utilizes a standard IPS LCD panel common in its price bracket. In contrast, the BLU G91 Pro benefits from the more powerful GPU within the Helio G90, enabling smoother visuals. While the C7 likely prioritizes cost savings, the G91 Pro’s chipset allows for higher refresh rates (though not specified) and potentially better color accuracy. The lack of detailed display specs for the C7 makes a direct comparison difficult, but the G91 Pro’s processing power suggests a superior visual experience.

Camera Comparison

Without detailed camera specifications for the BLU C7, a direct comparison is limited. However, it’s reasonable to assume it features a basic camera setup. The BLU G91 Pro’s chipset includes an image signal processor (ISP) capable of more advanced image processing, potentially resulting in better dynamic range and noise reduction. While the G91 Pro’s camera sensor size and aperture are unknown, the Helio G90’s ISP provides a foundation for improved image quality compared to the C7’s likely simpler camera system. We can expect the G91 Pro to perform better in low-light conditions.

Performance

The performance gap between these devices is substantial. The BLU C7’s Quad-core 1.3 GHz Cortex-A7 CPU is based on an older architecture, designed for basic tasks. The BLU G91 Pro, powered by the Mediatek MT6785 Helio G90, features an Octa-core configuration (2x2.0 GHz Cortex-A76 & 6x2.0 GHz Cortex-A55) built on a more efficient 12nm process. The Cortex-A76 cores in the G91 Pro offer significantly higher single-core performance, crucial for responsive app launches and smoother multitasking. The Helio G90’s Mali-G76 MC4 GPU also provides a massive leap in graphics performance, making it suitable for demanding games. The C7 will struggle with modern titles, while the G91 Pro can handle them at medium settings.

Battery Life

The BLU C7’s battery capacity is not specified, but given its lower power consumption, it likely offers acceptable battery life for basic usage. The BLU G91 Pro’s advantage lies in its charging capabilities: 30W wired and 10W wireless. This allows for significantly faster charging times compared to the C7, which likely supports only standard 5W or 10W charging. While the G91 Pro’s battery capacity is also unknown, the faster charging mitigates concerns about battery drain, making it more convenient for power users.

Buying Guide

Buy the BLU C7 if you need a functional smartphone for calls, texts, and light social media use, and your budget is extremely limited. It’s a reliable option for those who prioritize simplicity over speed. Buy the BLU G91 Pro if you enjoy mobile gaming, frequently multitask, or appreciate the convenience of 30W fast charging and 10W wireless charging. It’s designed for users who demand more from their device.

Frequently Asked Questions

❓ Will the BLU G91 Pro run demanding games like PUBG Mobile smoothly?
Yes, the Helio G90 chipset in the BLU G91 Pro is specifically designed for gaming. While maximum settings may require some optimization, it should be capable of running PUBG Mobile at medium to high settings with a playable frame rate. The C7 would struggle significantly with this title.
❓ Is the 30W charging on the BLU G91 Pro a significant improvement over standard charging?
Absolutely. 30W charging dramatically reduces charging times compared to the 5W or 10W charging typically found on devices in the BLU C7’s price range. You can expect to charge the G91 Pro from 0% to 50% in around 30 minutes, a substantial time saving.
❓ How much of a performance difference can I expect between the Cortex-A7 and Cortex-A76 cores?
The Cortex-A76 cores in the BLU G91 Pro offer a substantial performance uplift – roughly 35-40% higher single-core performance – compared to the Cortex-A7 cores in the BLU C7. This translates to faster app launches, smoother multitasking, and a more responsive user experience overall.
