Realme P3 (128GB / 8GB RAM) VS Vivo T4x 5G

In terms of physical footprint, the two phones are remarkably close. The Realme P3 measures 163.2 × 75.7 × 8 mm and weighs 194 g, while the Vivo T4x 5G is slightly larger at 165.7 × 76.3 × 8.1 mm and heavier at 204 g. That 10-gram difference is noticeable over extended one-handed use — the Realme will feel marginally more comfortable during long sessions, though neither phone is particularly light for its class.

The more meaningful distinction lies in water protection. The Realme P3 carries an IP68 rating, meaning it is fully waterproof and can withstand submersion in water up to a defined depth and duration. The Vivo T4x 5G, by contrast, holds only an IP64 rating, which offers protection against water splashes and jets but no submersion capability. In practical terms, the Realme can survive an accidental drop in a sink or shallow pool, while the Vivo is only safe against rain or spills.

Both devices share a non-rugged, non-foldable form factor, so there is no structural differentiation there. Overall, the Realme P3 holds a clear design-tier advantage — it is lighter, marginally slimmer, and significantly better protected against water ingress, making it the stronger choice for users who prioritize durability and everyday handling comfort.

Screen size, resolution, and refresh rate are essentially identical between these two phones — both offer a roughly 6.7-inch panel at 1080p resolution, ~394 ppi pixel density, and a 120Hz refresh rate. In day-to-day use, none of those differences are perceptible. The comparison therefore hinges almost entirely on one factor: panel technology.

The Realme P3 uses an OLED/AMOLED display, while the Vivo T4x 5G uses an IPS LCD. This is a significant qualitative gap. AMOLED panels produce true blacks by switching off individual pixels, resulting in vastly superior contrast ratios and more vibrant colors — especially visible when watching dark-scene content or using dark mode. They also enable more power-efficient rendering of dark interfaces, since unlit pixels draw no current. IPS LCD, while capable of accurate color reproduction, relies on a backlight that cannot be fully extinguished, leading to less punchy contrast and slightly higher power draw in low-light scenarios.

Neither display supports HDR10, HDR10+, or Dolby Vision, and neither features branded damage-resistant glass, so those axes are a wash. The Realme P3 holds a clear display advantage solely due to its AMOLED panel — a technology difference that meaningfully affects visual quality and is immediately noticeable to most users.

Both phones are built on a 4nm process node and match on RAM (8GB), maximum expandable memory (16GB), DDR5 standard, thread count, and DirectX 12 support — so the foundational architecture is comparable. The AnTuTu scores tell the same story: 684,046 for the Realme P3 versus 685,000 for the Vivo T4x 5G is a statistical dead heat, meaning general app performance and multitasking will feel indistinguishable in everyday use.

Dig deeper into the benchmarks, though, and a split emerges. The Snapdragon 6 Gen 4 in the Realme pulls ahead in Geekbench 6, scoring 1,104 single-core and 3,105 multi-core against the Dimensity 7300's 1,031 and 2,827 respectively. Single-core performance is particularly relevant for UI responsiveness and latency-sensitive tasks. On the flip side, the Vivo's Mali G615 MC2 GPU runs at a notably higher clock speed (1,047 MHz vs 800 MHz), and its RAM operates at 6,400 MHz — more than double the Realme's 2,750 MHz — which can benefit memory-bandwidth-intensive workloads. One concrete advantage the Vivo holds outright is 256GB of base storage versus the Realme's 128GB.

On balance, this category is tightly contested. The Realme P3 has a measurable CPU edge that matters for general snappiness, while the Vivo T4x 5G counters with faster RAM, a higher GPU clock, and double the storage. Users who prioritize raw processing feel will lean toward the Realme; those who value storage headroom and memory bandwidth will find the Vivo more compelling. Neither phone has a decisive overall performance advantage.

The rear camera systems start from an identical foundation — a 50 + 2 MP dual-lens setup, 4K at 30fps video, phase-detection autofocus, slow-motion, HDR, and a full suite of manual controls on both phones. Given how closely matched the hardware looks on paper, the differentiators come down to a few targeted specs that have outsized real-world impact.

The most consequential gap is optical image stabilization (OIS): the Realme P3 has it, the Vivo T4x 5G does not. OIS physically compensates for hand tremor during shooting, which meaningfully reduces blur in low-light photos and stabilizes video footage. Its absence on the Vivo means users will rely entirely on electronic stabilization — a software crop that sacrifices some image quality and field of view. Also worth noting, the Realme's main lens aperture is listed as a consistent f/1.8, while the Vivo lists f/2.4 and f/1.8 across its two lenses, suggesting its primary shooter may operate at the narrower f/2.4 — letting in less light and potentially affecting low-light performance.

For selfies, the advantage stays with the Realme: its 16 MP front camera resolves significantly more detail than the Vivo's 8 MP unit, which matters for portrait shots and video calls. The Vivo's front aperture of f/2.1 is marginally wider than the Realme's f/2.4, but that modest light-gathering edge does not offset the resolution deficit. Taken together, the Realme P3 holds a clear camera advantage — OIS and a higher-resolution selfie camera are practical, everyday benefits that the Vivo T4x 5G cannot match in this category.

This is a rare category where the data tells a clear and simple story: every single spec listed is identical across both phones. Both run Android 15 and share the exact same feature set — from privacy controls (location, camera/microphone, app tracking) to usability features like split-screen, picture-in-picture, dynamic theming, offline voice recognition, and battery health checks.

Notably, neither phone receives direct OS updates — meaning both rely on their respective manufacturers (Realme and Vivo) to push Android updates, which can introduce delays compared to devices with guaranteed timely update schedules. This is a shared limitation worth keeping in mind for long-term software support, but it places both phones on equal footing.

This group is a complete tie. There is no software or OS feature advantage to be found on either side based on the provided data, and the operating system experience should feel functionally equivalent on both devices.

Battery capacity is where the Vivo T4x 5G carves out its clearest advantage in this comparison: its 6,500 mAh cell edges out the Realme P3's already generous 6,000 mAh. A 500 mAh difference at this capacity tier is modest in percentage terms (~8%), but on phones that are already engineered for endurance, it can translate to a meaningful extra 30–60 minutes of screen-on time depending on usage patterns — enough to matter on a heavy day.

Charging speeds are effectively identical — 45W on the Realme versus 44W on the Vivo — a 1W gap that will produce no perceptible real-world difference in charge times. Neither phone supports wireless charging, and both have sealed, non-removable batteries, so those axes are evenly matched.

The Vivo T4x 5G takes a narrow but genuine edge in this category purely on the strength of its larger battery. For users who prioritize maximum time away from a charger, it holds the advantage — though the Realme P3's 6,000 mAh is still a strong performer in its own right, and charging parity means neither phone has a replenishment advantage to compensate.

Audio is another category where the two phones are in complete lockstep. Both feature stereo speakers and drop the 3.5mm headphone jack, meaning wired audio requires a USB-C adapter on either device — a shared trade-off that is increasingly common at this price tier.

For wireless audio enthusiasts, neither phone supports any high-resolution Bluetooth codec — no aptX, no LDAC, no aptX HD or Adaptive. This means Bluetooth audio is limited to standard codecs (such as SBC or AAC), which is adequate for casual listening but falls short for users who want lossless or near-lossless wireless playback through premium headphones. Again, both phones are equally limited here.

This category is a complete tie. With identical speaker configurations, the same absence of a headphone jack, and matching Bluetooth audio codec support, there is no audio hardware advantage on either side based on the provided data.

The shared foundation here is solid — both phones support 5G, dual SIM, Wi-Fi 6, USB-C, GPS with Galileo, fingerprint scanning, gyroscope, accelerometer, compass, and an infrared sensor. For most users, these bases are all that is needed for a fully connected, modern experience. The real story lies in where the two devices diverge.

The most practically significant difference is NFC: the Realme P3 has it, the Vivo T4x 5G does not. NFC enables contactless payments, quick device pairing, and transit card functionality — everyday conveniences that are increasingly hard to live without for users in NFC-reliant markets. On the flip side, the Vivo counters with a newer Bluetooth 5.4 versus the Realme's 5.2, offering marginally improved connection stability and efficiency, though the practical day-to-day difference is minor. The Vivo also posts notably higher cellular speeds — particularly its upload rate of 3,270 Mbits/s compared to the Realme's 1,600 Mbits/s — which benefits users who frequently upload large files or stream live video over cellular.

Weighing these trade-offs, the Realme P3 holds the broader connectivity advantage for most users. NFC is a high-frequency, everyday feature whose absence on the Vivo is a tangible limitation, whereas the Vivo's faster upload ceiling and newer Bluetooth version are benefits that only specific use cases will regularly exploit.

The miscellaneous specs for these two phones are identical across every data point provided: both feature a video light, and neither has a sapphire glass display, a curved display, or an e-paper display. There are no differentiators to analyze here.

This category is a complete tie. No advantage can be assigned to either the Realme P3 or the Vivo T4x 5G based on the available data, and this group should not factor into a purchase decision between the two.
