Display Comparison

While specific display details are missing, both phones likely feature LCD or AMOLED panels common in this price bracket. However, the chipset difference indirectly impacts the display experience. The Dimensity 7300+’s superior GPU can drive higher refresh rates and more complex visuals with greater ease. The 4nm process also contributes to lower heat generation, potentially preventing display dimming under sustained load. We expect both to offer FHD+ resolution, but Realme's potential for a higher peak brightness is likely due to the more powerful processing capabilities.

Camera Comparison

Without detailed camera specs, it’s difficult to make a definitive judgment. However, the processing power of the Dimensity 7300+ in the Realme 15 will likely result in superior image processing, particularly in low-light conditions. The ISP (Image Signal Processor) within the 7300+ is more advanced, enabling better noise reduction and dynamic range. We anticipate both phones will include a primary camera, ultrawide, and depth sensor, but the Realme 15’s chipset will allow for more sophisticated computational photography features.

Performance

The core of the difference lies in the chipsets. The Realme 15’s Mediatek Dimensity 7300+ (4nm) boasts a newer architecture with four Cortex-A78 cores clocked at 2.6 GHz, compared to the Infinix Note 12 Pro 5G’s Dimensity 810 (6nm) featuring two Cortex-A76 cores at 2.4 GHz. The 4nm fabrication process of the 7300+ is a significant advantage, offering better power efficiency and thermal performance. This translates to sustained performance during gaming and demanding tasks, with less throttling. The A78 cores in the Realme 15 also provide a performance uplift over the A76 cores in the Infinix. While both utilize 8GB of RAM (assumed based on market segment), the Realme 15’s chipset is more capable of efficiently managing that memory.

Battery Life

The Realme 15’s 80W wired charging is a game-changer. It promises a 50% charge in just 25 minutes, significantly faster than the Infinix Note 12 Pro 5G’s 33W charging. While battery capacity isn’t specified, the more efficient Dimensity 7300+ in the Realme 15 will likely deliver comparable or better battery life despite potentially having a smaller battery size. The faster charging speed mitigates any potential capacity difference, offering more convenient top-ups throughout the day.

Buying Guide

Buy the Realme 15 (India) if you prioritize raw performance for gaming and demanding applications, and value significantly faster charging speeds. You'll benefit from a more future-proof chipset and a smoother overall experience. Buy the Infinix Note 12 Pro 5G if your budget is extremely tight and you primarily need a functional 5G smartphone for basic tasks; the Dimensity 810 is adequate for everyday use, but it won't excel in intensive workloads.

Frequently Asked Questions

❓ Will the Dimensity 810 in the Infinix Note 12 Pro 5G struggle with graphically intensive games like Genshin Impact?
Yes, the Dimensity 810 is likely to struggle with Genshin Impact and similar demanding titles. While playable at lower settings, you'll likely experience noticeable frame drops and throttling due to its less efficient 6nm process and less powerful GPU compared to the Dimensity 7300+.
