Display Comparison

While both phones likely feature AMOLED displays (based on market segment), the specifics aren't provided. However, the core difference lies beneath the surface. The Redmi K50’s chipset will likely drive a higher refresh rate display more smoothly. Samsung typically excels in color accuracy and outdoor visibility, but without nit brightness data, it’s difficult to definitively state which phone offers a superior viewing experience. Bezels are likely comparable, given both phones target a similar price bracket.

Camera Comparison

Without detailed sensor information, a direct comparison is challenging. However, the chipset’s image signal processor (ISP) plays a crucial role. The Dimensity 8100’s ISP is more advanced, potentially leading to better dynamic range and noise reduction in the Redmi K50’s photos. Samsung’s image processing tends to be more saturated and vibrant, which some users prefer. The absence of OIS information for either phone makes it difficult to assess low-light performance. We can assume both phones will have a primary camera, ultrawide, and potentially a macro lens, but the quality will heavily depend on the sensor size and aperture.

Performance

The Mediatek Dimensity 8100 (5nm) in the Redmi K50 is the clear performance leader. Its octa-core configuration, with four Cortex-A78 cores clocked at 2.85 GHz, significantly outpaces the Snapdragon 778G 5G (6nm) in the Galaxy A73, which has a single Cortex-A78 core at 2.4 GHz and three additional A78 cores. The 5nm process node of the Dimensity 8100 also contributes to better thermal efficiency, meaning sustained performance will be higher during prolonged gaming sessions. The Galaxy A73’s Snapdragon 778G is still a capable chip, but it’s geared towards efficient everyday tasks rather than intensive workloads. The Redmi K50 will show a noticeable advantage in graphically demanding games and video rendering.

Battery Life

The Redmi K50’s 67W wired charging is a game-changer. It can reportedly reach 80% charge in just 30 minutes, a significant advantage over the Galaxy A73’s 25W charging. While battery capacity isn’t specified, the faster charging speed mitigates any potential difference in mAh. The 6nm process of the Snapdragon 778G in the A73 is more efficient, but the Dimensity 8100’s performance advantage likely offsets this. Users who frequently top up their phones will greatly appreciate the Redmi K50’s charging speed.

Buying Guide

Buy the Xiaomi Redmi K50 if you need a phone that excels in demanding tasks like gaming and video editing, and if you value incredibly fast charging speeds. You’ll benefit from a more powerful processor and a quicker top-up. Buy the Samsung Galaxy A73 5G if you prefer a more polished software experience, a well-established brand ecosystem, and a potentially more consistent camera experience, even if it means sacrificing some raw processing power.

Frequently Asked Questions

❓ Will the Redmi K50 get noticeably hotter than the Galaxy A73 during extended gaming sessions?
Yes, the Snapdragon 778G in the Galaxy A73 is more thermally constrained. The Dimensity 8100’s 5nm process and potentially better cooling solution in the Redmi K50 will allow it to maintain higher clock speeds for longer periods without significant throttling, resulting in a cooler experience.
❓ Is the 67W charging on the Redmi K50 compatible with all USB-C chargers?
The Redmi K50 supports PD3.0 and QC3, meaning it will work with most USB-C chargers. However, to achieve the full 67W charging speed, you’ll need a charger that specifically supports these protocols. Using a standard USB-C charger will still charge the phone, but at a slower rate.
❓ Does the Snapdragon 778G in the Galaxy A73 support frame interpolation to achieve 120Hz smoothness in games?
The Snapdragon 778G does support frame interpolation technologies, but the effectiveness varies depending on the game and the implementation. While it can improve perceived smoothness, it doesn’t truly render frames at 120Hz if the game natively supports only 60Hz.
