Infinix Note 50 Pro 4G VS Infinix Note 50x 5G

Both the Infinix Note 50 Pro 4G and the Note 50x 5G share the same IP64 water resistance rating, meaning neither is fully submersible but both can handle splashes and light rain with confidence. Neither adopts a rugged build or a foldable form factor, so they sit squarely in the standard slab smartphone category.

Where the two diverge meaningfully is in physical footprint. Despite weighing almost identically — 198 g versus 198.9 g — the Note 50 Pro 4G is noticeably more compact: at 7.3 mm thick, it undercuts the Note 50x 5G's 8 mm by a significant 0.7 mm, and it is also narrower (74.4 mm vs 76.4 mm) and shorter (163.3 mm vs 165.4 mm). This compounds into a volume difference of roughly 88.7 cm³ against 101.1 cm³ — the Note 50 Pro 4G occupies about 12% less space. In the hand, that slimmer profile and tighter frame will feel noticeably easier to grip one-handed and more pocketable day-to-day.

On design, the Note 50 Pro 4G holds a clear edge: it achieves the same weight class and identical weather protection in a significantly slimmer and more refined chassis, which translates directly to better ergonomics and portability.

The display is arguably where the gap between these two phones is most dramatic. The Note 50 Pro 4G uses an OLED/AMOLED panel, while the Note 50x 5G relies on an LCD IPS screen — a fundamental technology difference that shapes the entire viewing experience. OLED delivers true blacks, higher contrast, and more vivid colors because each pixel produces its own light, while LCD depends on a backlight that limits both contrast depth and power efficiency. For media consumption, dark-theme apps, and anything color-sensitive, the OLED panel is in a different league.

The resolution gap reinforces this advantage. The Note 50 Pro 4G resolves at 1080 x 2436 px and 393 ppi, versus the Note 50x 5G's 720 x 1600 px at just 263 ppi — a difference that is plainly visible to the naked eye when reading text or viewing detailed images. The Pro 4G also steps up to a 144Hz refresh rate compared to 120Hz on the 50x 5G, meaning slightly smoother scrolling and animations, though both are above the threshold where most users notice diminishing returns. One additional exclusive on the Pro 4G is its Always-On Display support, a convenience feature the 50x 5G lacks entirely.

Brightness is the one area where the two are essentially tied — 550 nits versus 560 nits — so outdoor legibility is comparable. But on every other meaningful display metric, the Note 50 Pro 4G holds an overwhelming advantage, making it the clear choice for anyone who prioritizes screen quality.

Under the hood, the Note 50x 5G pulls decisively ahead. Its MediaTek Dimensity 7300 chip is built on a 4 nm process versus the Note 50 Pro 4G's MediaTek Helio G100 on 6 nm — a smaller node translates directly to better power efficiency and thermal headroom. The benchmark numbers tell the same story: the Note 50x 5G scores approximately 720,000 on AnTuTu against the Note 50 Pro 4G's 438,000, a gap of over 60% that is large enough to be felt in demanding games, heavy multitasking, and sustained app performance.

The memory architecture also favors the Note 50x 5G at every level. It pairs its chip with DDR5 RAM at 6400 MHz, while the Pro 4G uses DDR4 at 4266 MHz — faster memory reduces latency and improves how quickly data is fed to the processor. The Note 50x 5G's GPU also supports DirectX 12 versus DirectX 11 on the Pro 4G, meaning it is better positioned for modern graphics workloads. Where the Note 50 Pro 4G does hold a concrete advantage is raw storage and starting RAM: it ships with 256 GB of internal storage and 12 GB of RAM, compared to 128 GB and 8 GB on the Note 50x 5G. For users who prioritize onboard space and multitasking headroom without relying on speed, that matters.

Overall, the Note 50x 5G holds a clear performance edge in processing power, memory speed, and GPU capability. The Note 50 Pro 4G counters with more storage and slightly more RAM, but for raw compute performance the Dimensity 7300 outclasses the Helio G100 by a substantial margin.

The camera comparison here is genuinely split, with each phone winning in distinct areas. On the rear, both share a 50 MP primary sensor, but the Note 50x 5G's main lens opens to f/1.6 — meaningfully wider than the Note 50 Pro 4G's f/1.9 — which allows more light to hit the sensor and should yield better results in dim conditions. The Note 50x 5G also edges ahead on video, capturing up to 4K at 30 fps versus the Pro 4G's 1440p at 30 fps, a real advantage for users who shoot video and want higher-resolution footage.

The Note 50 Pro 4G fights back in two important ways. First, it includes optical image stabilization (OIS), which the Note 50x 5G lacks entirely — OIS physically compensates for hand movement, producing noticeably sharper handheld photos and smoother video without relying purely on software. Second, it adds a secondary 8 MP lens, expanding its versatility beyond a single focal length. Its front camera is also a significant step up: 32 MP against just 8 MP on the Note 50x 5G, making it a considerably stronger choice for selfies and video calls.

The verdict depends on use case. For main-camera low-light photography and video resolution, the Note 50x 5G has the edge. For overall versatility — stabilized shots, multi-lens flexibility, and a far superior selfie camera — the Note 50 Pro 4G is the stronger all-rounder.

On the software front, these two phones are identical in every measurable way. Both ship with Android 15 and offer the same complete set of privacy controls — including location permissions, camera and microphone access management, and app tracking blocks — giving users equivalent control over their data on either device.

The feature parity extends throughout the OS experience: both support split-screen multitasking, Picture-in-Picture, dynamic theming, widgets, offline voice recognition, and on-device machine learning. Neither receives direct OS updates from Google, and neither includes Wi-Fi password sharing or focus modes. In short, there is no software capability that one phone has and the other lacks.

This group is a complete tie. A buyer's software experience will be functionally indistinguishable between the two, so the operating system should carry no weight in the decision between the Infinix Note 50 Pro 4G and the Note 50x 5G.

Battery capacity is close but not identical: the Note 50x 5G carries a 5500 mAh cell versus 5200 mAh in the Note 50 Pro 4G. The 300 mAh difference is modest and unlikely to translate to dramatically different screen-on time in practice, though the Note 50x 5G holds a marginal edge for raw endurance — particularly relevant given that its 5G radio can draw more power during connectivity.

Where the two diverge sharply is in charging. The Note 50 Pro 4G supports 90W wired fast charging and adds wireless charging — a combination the Note 50x 5G cannot match. At 90W, the Pro 4G's slightly smaller battery will charge to full in a fraction of the time it takes the Note 50x 5G at 45W. Wireless charging, while typically slower, adds meaningful convenience for users with compatible pads at home or the office. The Note 50x 5G's 45W charging is respectable but is outpaced on both wired speed and charging flexibility.

This group has no single outright winner — it depends on priorities. For maximum endurance and minimal charging anxiety, the Note 50x 5G's larger battery is the safer bet. For faster top-ups and charging versatility, the Note 50 Pro 4G's 90W wired and wireless charging system is the stronger package.

Audio is another category where the two phones are in complete lockstep. Both feature stereo speakers and a built-in FM radio, while neither offers a 3.5 mm headphone jack — meaning wired headphone users on either device will need a USB-C adapter or a wireless solution.

On the wireless audio quality front, neither phone supports any high-resolution Bluetooth codecs: aptX, aptX HD, LDAC, aptX Adaptive, and aptX Lossless are all absent on both. Users who rely on Bluetooth headphones will be limited to standard codecs, which is a shared limitation rather than a differentiator between the two.

This group is a complete tie. Every audio specification is identical across the Infinix Note 50 Pro 4G and the Note 50x 5G, so sound capability should play no role in choosing between them.

Cellular and wireless connectivity is where the Note 50x 5G justifies its name most clearly. It supports 5G — which the Note 50 Pro 4G entirely lacks — and pairs that with Wi-Fi 6 (802.11ax), while the Pro 4G tops out at Wi-Fi 5. The real-world impact is substantial: the Note 50x 5G's theoretical download and upload speeds reach 3270 Mbits/s, compared to 650 Mbits/s down and 150 Mbits/s up on the Pro 4G. For users in 5G-covered areas or on congested Wi-Fi 6 networks, that headroom translates to faster downloads, smoother streaming, and lower latency.

Shared foundations are solid on both sides: each phone includes NFC, Bluetooth 5.4, dual-SIM support, USB Type-C, GPS with Galileo, a fingerprint scanner, and a gyroscope and accelerometer. The Note 50x 5G also adds an infrared sensor, useful for controlling TVs and home appliances — a small but practical bonus. The Note 50 Pro 4G counters with a heart rate monitor, absent on the Note 50x 5G, which may appeal to health-conscious users who want basic biometric tracking without a wearable.

Connectivity overall goes decisively to the Note 50x 5G — its 5G support and Wi-Fi 6 capability represent a genuine generational step forward in network performance. The Pro 4G's heart rate monitor is a niche advantage, but it cannot offset the breadth of the Note 50x 5G's connectivity lead.

The miscellaneous specs for these two phones offer no points of differentiation whatsoever. Both include a video light, and neither features a sapphire glass display, a curved screen, or an e-paper panel — four for four, identical across the board.

This is a complete tie. Nothing in this specification group should factor into a decision between the Infinix Note 50 Pro 4G and the Note 50x 5G.
