BLU consistently targets the ultra-budget smartphone market, and the G50 Mega and G51 represent two of their recent offerings. While both aim to deliver affordability, they take different approaches to processing power. The G50 Mega utilizes an octa-core Cortex-A55, while the G51 opts for the MediaTek Helio A22. This comparison dissects these core differences and determines which device provides the best user experience for the price.
🏆 Quick Verdict
For the average user prioritizing responsiveness in everyday tasks, the BLU G51 is the better choice. Its 2.0 GHz quad-core Helio A22, despite having fewer cores, offers a higher clock speed than the G50 Mega’s 1.6 GHz Cortex-A55, resulting in snappier app launches and smoother multitasking. However, the G50 Mega’s potential for longer battery life due to the more efficient core architecture shouldn't be dismissed.

BLU G50 Mega
- Potentially longer battery life due to Cortex-A55 efficiency.
- Octa-core processor may handle background tasks slightly better.
- Likely similar price point to the G51.
- Lower CPU clock speed results in slower app launches.
- Cortex-A55 architecture is less performant in single-core tasks.
- Likely similar camera performance to the G51.
BLU G51
- Higher CPU clock speed (2.0 GHz) for snappier performance.
- Helio A22’s 12nm process node offers better efficiency.
- More responsive user experience for everyday tasks.
- Quad-core processor may struggle with heavy multitasking.

- Similar camera performance to the G50 Mega.
Display Comparison
Neither BLU provides display specifications beyond size. Given their price point, it's safe to assume both utilize LCD panels with 720p+ resolutions. The lack of information regarding brightness, color gamut coverage, or refresh rates suggests a focus on cost reduction. Bezels are likely to be substantial on both devices, and color accuracy will likely be standard for this segment.
Camera Comparison
Both devices likely feature basic camera setups. Without specific sensor details, it’s difficult to make a meaningful comparison. It’s reasonable to assume both phones include a primary camera and potentially a secondary depth or macro sensor. Image quality will be heavily reliant on software processing, and users shouldn’t expect flagship-level performance. The absence of OIS (Optical Image Stabilization) on either device suggests low-light performance will be limited.
Performance
The core difference lies in the processors. The BLU G51’s MediaTek Helio A22 (12nm) features four Cortex-A53 cores clocked at 2.0 GHz. This higher clock speed provides a performance advantage over the BLU G50 Mega’s octa-core Cortex-A55 processor running at 1.6 GHz. While the G50 Mega has more cores, the A53 architecture in the Helio A22 is generally more efficient at single-core tasks, which are crucial for app responsiveness. The 12nm process node of the Helio A22 also contributes to better power efficiency compared to the likely larger process node of the Cortex-A55. Neither device is expected to handle demanding games or intensive multitasking with ease.
Battery Life
The BLU G50 Mega and G51 both feature 10W wired charging. While the battery capacity isn't specified, the Cortex-A55 architecture in the G50 Mega is generally more power-efficient than the A53 in the G51. This suggests the G50 Mega *could* offer slightly longer battery life, despite potentially having a similar capacity. However, the G51’s more efficient processor usage during active tasks might offset this advantage. A full 0-100% charge on either device will likely take over 3 hours with the included 10W charger.
Buying Guide
Buy the BLU G50 Mega if you prioritize maximizing battery life and primarily use your phone for very basic tasks like calls, texts, and light social media browsing. Buy the BLU G51 if you prefer a more responsive user experience for everyday app usage, even if it means potentially sacrificing some battery longevity. The G51 is better suited for users who occasionally play less demanding mobile games or use multiple apps simultaneously.
Frequently Asked Questions
❓ Will the BLU G51 be able to run popular social media apps like TikTok and Instagram smoothly?
Yes, the BLU G51’s 2.0 GHz Helio A22 processor should be capable of running TikTok and Instagram without significant lag. While it won’t offer a high-end experience, it will provide a usable experience for browsing feeds and recording short videos. The G50 Mega will run these apps, but with potentially more noticeable slowdowns.
❓ Is the 10W charging speed on either phone sufficient for daily use?
10W charging is quite slow by modern standards. Expect a full charge to take over three hours. Neither the G50 Mega nor the G51 are designed for quick top-ups. Users should plan to charge overnight to ensure they have sufficient battery life for the day.
❓ Can either of these phones handle basic mobile games like Candy Crush or Subway Surfers?
Both the BLU G50 Mega and G51 can handle casual games like Candy Crush and Subway Surfers. However, don't expect high frame rates or detailed graphics. The Helio A22 in the G51 will likely provide a slightly smoother experience, but neither phone is a gaming device.
