In terms of physical dimensions, the two phones are remarkably close. The Realme C75 5G is marginally taller and wider, while the Realme P3 is very slightly thicker at 8 mm versus 7.9 mm. The weight difference — 190 g vs. 194 g — is negligible in daily handling. Neither device folds or carries a rugged-build designation, so both target the mainstream form factor segment.

The most meaningful differentiator in this group is water protection. The C75 5G carries an IP64 rating, which means it is shielded against dust and can handle water splashes from any direction — but it cannot be submerged. The Realme P3 steps up to IP68, a certification that covers full dust ingress protection and submersion in water beyond 1 meter. In real-world terms, the P3 can survive an accidental drop in a sink or a pool, whereas the C75 5G should only be trusted to weather rain or a countertop splash.

The Realme P3 holds a clear advantage in this group, driven entirely by its superior IP68 waterproofing. The dimensional and weight differences are too small to influence a purchase decision, but the jump from IP64 to IP68 represents a genuinely higher tier of durability that matters for users with active lifestyles or accident-prone habits.

Both phones share the same 6.67″ screen size and a smooth 120Hz refresh rate, so scrolling and animations feel equally fluid on either device. That surface-level parity, however, masks a substantial gap underneath. The C75 5G uses an LCD IPS panel at 720 x 1604 px, yielding a pixel density of just 264 ppi — enough for casual use, but text and fine detail will appear noticeably softer at close range. The Realme P3 counters with an OLED/AMOLED panel at 1080 x 2400 px and 395 ppi, a density jump that produces crisp, sharp imagery that is clearly visible even when scrutinizing small fonts or high-resolution photos.

Beyond sharpness, the panel technology difference carries real perceptual weight. AMOLED screens render blacks by switching pixels off entirely, producing infinite contrast and more saturated colors compared to the backlit nature of IPS LCD. For media consumption — streaming, gaming, or photo browsing — the P3's display will look distinctly more vivid and punchy. The C75 5G's LCD is perfectly serviceable for everyday tasks but cannot match that visual depth.

The Realme P3 wins this category decisively. Its AMOLED panel combined with a significantly higher 395 ppi resolution delivers a display experience that is a full tier above what the C75 5G's LCD can offer, making it the stronger choice for anyone who values screen quality.

The chipset gap here is hard to ignore. The C75 5G runs on a MediaTek Dimensity 6300 built on a 6 nm process, while the Realme P3 houses a Qualcomm Snapdragon 6 Gen 4 on a more advanced 4 nm node. A smaller process node generally means better power efficiency and more thermal headroom — and the benchmark numbers confirm the advantage is real. The P3 scores 3105 in Geekbench 6 multi-core versus 2012 for the C75 5G, and 1104 versus 782 in single-core. That roughly 40–54% lead in CPU throughput translates to noticeably snappier app launches, smoother multitasking, and more headroom for demanding tasks like video editing or gaming.

Memory tells a similarly one-sided story. Both phones ship with 8 GB of RAM, but the P3 uses faster DDR5 at 2750 MHz versus the C75 5G's DDR4 at 2133 MHz. The P3 also supports a higher maximum memory configuration of 16 GB versus 12 GB, giving it more ceiling for future variants. On storage, the P3 doubles up with 256 GB base capacity against the C75 5G's 128 GB — a meaningful difference for users who store media locally. One nuance worth noting: the C75 5G posts a higher maximum memory bandwidth of 17.07 GB/s versus 12 GB/s on the P3, though this single metric does not offset the broader performance deficit.

The Realme P3 wins the performance category convincingly. Its newer process node, significantly higher benchmark scores, faster RAM standard, and larger base storage combine into a package that is clearly better equipped for sustained, demanding workloads than the C75 5G.

The rear camera systems diverge in several meaningful ways. The C75 5G fields a single 32 MP shooter, while the Realme P3 goes with a dual-lens setup led by a 50 MP primary sensor — giving it both a higher resolution main camera and an additional depth lens for portrait shooting. More impactful than the megapixel count, though, is the P3's inclusion of optical image stabilization (OIS), a feature absent on the C75 5G. OIS physically compensates for hand tremor during shooting, which meaningfully reduces blur in low-light photos and produces steadier handheld video — something no software processing can fully replicate.

The video capability gap reinforces the P3's advantage. It tops out at 4K 30fps recording versus the C75 5G's ceiling of 1080p 30fps. For anyone who shoots video for social media or wants footage with enough resolution to crop in post, that difference is immediately practical. Selfie performance also shifts in the C75 5G's favor on one narrow point: its front camera has a wider f/2.0 aperture compared to the P3's f/2.4, which allows more light in — though the P3's 16 MP front sensor outresolves the C75 5G's 8 MP by a wide margin. Higher resolution wins for detail and cropping flexibility, making the P3's selfie camera the stronger all-rounder despite the aperture trade-off.

The Realme P3 holds a clear edge across the camera group. OIS, a higher-resolution dual rear system, and 4K video recording collectively represent a more capable imaging package, and no individual spec on the C75 5G is strong enough to offset that advantage.

This is a rare case of a complete tie. Both the Realme C75 5G and the Realme P3 run Android 15 and share an identical feature set across every single data point in this group — from privacy controls like camera and microphone toggles, location options, and app tracking blockers, to usability features like dark mode, dynamic theming, split-screen multitasking, Picture-in-Picture, and offline voice recognition.

Notably, neither device receives direct OS updates — meaning software upgrades are routed through Realme's own UI layer rather than pushed straight from Google. Users on both phones are equally subject to Realme's update cadence. The absence of features like Wi-Fi password sharing, cross-site tracking blocking, and focus modes is also shared, so no advantage exists on either side of those gaps.

This category is a draw. With every tracked software specification matching exactly, the operating system experience offers no basis for choosing one phone over the other.

Battery:
battery power 6000 mAh 6000 mAh
has wireless charging
Supports fast charging
charging speed 45W 45W
has a removable battery
has a battery level indicator
has a rechargeable battery

Battery is another category where the two phones are perfectly matched. Both the Realme C75 5G and the Realme P3 pack a 6000 mAh cell — a capacity that sits firmly in the large-battery segment and is generally associated with all-day and into-the-next-day endurance for moderate users. Neither device supports wireless charging, and both top out at 45W wired fast charging, which at this power level can typically bring a 6000 mAh battery from empty to a meaningful charge in roughly an hour.

The complete spec parity here means that on paper, neither phone has a charging or longevity advantage over the other. It is worth noting, however, that real-world battery life is also influenced by display and chipset efficiency — factors covered in other groups — where the two phones do differ. But strictly within the data provided for this category, there is nothing to separate them.

This is a draw. With identical battery capacity, charging speed, and every other tracked attribute aligned, the battery group offers no differentiating factor between the two devices.

Audio:
has a socket for a 3.5 mm audio jack
has stereo speakers
has aptX
has LDAC
has aptX HD
has aptX Adaptive
has aptX Lossless

Audio comes down to a straightforward trade-off between two different listener priorities. The C75 5G retains a 3.5 mm headphone jack but outputs sound through a single mono speaker, while the Realme P3 drops the jack entirely in exchange for stereo speakers. Neither phone supports advanced wireless audio codecs like aptX or LDAC, so Bluetooth audio quality is on equal footing for both.

The practical implications depend entirely on how you consume audio. Wired headphone users — particularly those who own quality earphones or prefer the reliability and zero-latency nature of a physical connection — will find the C75 5G more accommodating without needing an adapter. The P3's stereo speaker setup, on the other hand, produces a wider, more immersive soundstage for speakerphone calls, media playback, and gaming, where a second driver creates genuine left-right separation that a mono setup cannot replicate.

There is no outright winner here — the edge belongs to whichever use case matters more to the buyer. The C75 5G suits wired audio users, while the Realme P3 is the stronger choice for anyone who primarily listens through the phone's own speakers.

The shared foundation is solid on both devices — 5G, NFC, USB-C, dual SIM, GPS, and a fingerprint scanner are all present across the board. Where things diverge is in a handful of specific but meaningful features. The Realme P3 supports Wi-Fi 6 (802.11ax) in addition to Wi-Fi 4 and 5, while the C75 5G tops out at Wi-Fi 5. Wi-Fi 6 delivers better throughput and significantly improved performance in congested environments — like homes with many connected devices — making it a worthwhile upgrade for users on compatible routers.

The sensor and expandability split is where the two phones pull in opposite directions. The C75 5G includes a microSD card slot, a practical advantage for users who want to expand storage affordably or transfer files easily — something the P3 entirely lacks. The P3 counters with a gyroscope and an infrared sensor, neither of which the C75 5G carries. The gyroscope unlocks accurate motion-based controls in games and AR applications, while the IR blaster lets the phone function as a universal remote for TVs and appliances. One minor note: the C75 5G edges ahead on Bluetooth 5.3 versus the P3's 5.2, though the practical difference between these adjacent versions is negligible for most users.

This category is closely contested, but the Realme P3 holds a slight overall edge. Wi-Fi 6 and the gyroscope are broadly useful upgrades, and the IR blaster is a genuine convenience feature. The C75 5G's memory card slot is a meaningful win for storage-focused users, but it does not fully offset the P3's connectivity and sensor advantages.

Miscellaneous:
has a video light
Has sapphire glass display
Has a curved display
Has an e-paper display

The miscellaneous group offers nothing to separate these two devices. Every tracked attribute — the presence of a video light, the absence of sapphire glass, a curved display, and an e-paper panel — is identical across both the Realme C75 5G and the Realme P3.

This is a draw. With no differentiating data points in this category, it has no bearing on the decision between the two phones.

Comparison Summary & Verdict

After weighing all the evidence, the Realme C75 5G and Realme P3 target meaningfully different users. The Realme C75 5G stands out with its IP64-rated water resistance, a convenient 3.5mm headphone jack, and expandable storage support — solid perks for users who value everyday practicality and flexibility. On the other hand, the Realme P3 is the clear choice for those who demand more from their device: its OLED display with 395 ppi, IP68 waterproof rating, Snapdragon 6 Gen 4 chipset, 4K video recording, optical image stabilization, stereo speakers, and Wi-Fi 6 support collectively position it as the more premium and future-proof option. If budget and core essentials are your priority, the Realme C75 5G delivers. But if you want a sharper, more capable all-rounder, the Realme P3 is the stronger investment.
