CMF Phone 2 Pro VS Realme P3 Ultra 5G

Both phones are remarkably close in physical form, but the most meaningful differentiator here is water protection. The CMF Phone 2 Pro carries an IP54 rating, which means it can handle splashes and light rain but is not safe for submersion. The Realme P3 Ultra 5G steps up significantly with an IP68 rating, making it fully dustproof and capable of surviving submersion in water up to a defined depth — a level of protection that genuinely matters for everyday accidents like drops in a sink or caught in heavy rain.

On the physical dimensions, the differences are marginal. The CMF Phone 2 Pro is slightly heavier at 185 g versus 183 g, and a touch thicker at 7.8 mm compared to 7.4 mm. In practice, neither of these gaps is perceptible during daily use, and neither device opts for a rugged or foldable build.

The Realme P3 Ultra 5G holds a clear edge in this category, and it is not a close call — the jump from IP54 to IP68 is a substantial real-world advantage, offering meaningful peace of mind that the CMF Phone 2 Pro simply cannot match.

Sharing the same OLED/AMOLED panel technology and a 120Hz refresh rate, both phones deliver smooth, vibrant visuals as a baseline. Where they diverge is meaningful, however. The Realme P3 Ultra packs a notably sharper display at 446 ppi versus the CMF Phone 2 Pro's 388 ppi, driven by its higher 1220 x 2712 resolution on a slightly smaller 6.67″ screen. That pixel density gap is visible — fine text, detailed photography, and UI elements will appear crisper on the Realme.

Flip the scorecard to features, though, and the CMF Phone 2 Pro pulls ahead on multiple fronts. Its larger 6.77″ panel is paired with branded damage-resistant glass — an everyday durability advantage the Realme lacks entirely. It also supports both HDR10 and HDR10+, meaning compatible streaming content renders with greater dynamic range and more accurate highlights. On top of that, its Always-On Display lets users glance at time and notifications without waking the screen — a convenience the Realme does not offer.

This is a genuine trade-off rather than a clean sweep. Users who prioritize raw sharpness will prefer the Realme P3 Ultra. However, the CMF Phone 2 Pro holds the broader display advantage — combining a larger screen, glass protection, richer HDR support, and Always-On functionality — making it the stronger all-round pick for this category.

On paper, both phones share a 4nm process node and the same 8-thread big.LITTLE architecture, but the chipsets inside them occupy very different performance tiers. The CMF Phone 2 Pro runs on the MediaTek Dimensity 7300, while the Realme P3 Ultra deploys the considerably more powerful Dimensity 8350. The benchmark numbers make the gap impossible to ignore: the Realme scores roughly 1,450,000 on AnTuTu versus the CMF's 711,907 — that is nearly double the throughput. Geekbench 6 tells the same story, with the Realme pulling 1536 single-core and 4700 multi-core against 1007 and 2874 respectively. In practice, this translates to noticeably snappier app launches, smoother multitasking under load, and more headroom for demanding games.

The GPU gap reinforces this further. The Realme's Mali G615 MC6 runs at 1400 MHz with six cores, compared to the CMF's Mali G615 MC2 at 1047 MHz with just two — a threefold difference in GPU cores that directly benefits graphically intensive workloads. The Realme also ships with 12GB of RAM at 8533 MHz, versus 8GB at 6400 MHz on the CMF, meaning it can keep more apps resident in memory and feed the processor data faster. Maximum supported RAM also favors the Realme at 24GB versus 16GB.

The Realme P3 Ultra wins this category decisively and across every meaningful dimension — raw CPU performance, GPU capability, memory speed, and headroom for future demands. The CMF Phone 2 Pro is no slouch for everyday tasks, but users who care about sustained performance, gaming, or heavy multitasking will find the Realme in a different league.

The most structurally important difference in this category is the rear camera configuration. The CMF Phone 2 Pro fields a triple-lens system — 50 + 50 + 8 MP — giving it dedicated hardware for multiple focal perspectives, backed by 2x optical zoom. Optical zoom uses physical lens movement to magnify a subject without degrading image quality, something digital zoom cannot replicate. The Realme P3 Ultra, despite also having a multi-lens rear setup, lists 0x optical zoom, meaning any magnification beyond its main lens is purely digital — a meaningful limitation for anyone who regularly shoots at a distance.

Where the Realme reclaims ground is in video. It captures 4K footage at 60 fps versus the CMF's 4K at 30 fps — a difference that produces noticeably smoother motion in fast-moving scenes and gives videographers more flexibility when editing. Both phones share OIS, phase-detection autofocus, slow-motion support, and an identical 16MP front camera, so the foundations are evenly matched. One subtle front-camera distinction: the CMF's f/2.0 aperture is wider than the Realme's f/2.4, which allows more light in and can benefit selfies in dimmer conditions.

On balance, the CMF Phone 2 Pro holds the camera edge for most users — optical zoom and a more versatile multi-lens array are practical, everyday advantages that the Realme's 4K/60fps capability only partially offsets. Dedicated video creators may lean toward the Realme, but for general photography the CMF is the stronger choice here.

Rarely does a spec group produce a result this clear-cut: the CMF Phone 2 Pro and Realme P3 Ultra are identical across every single operating system data point provided. Both ship with Android 15, share the same privacy controls — including location, camera, and microphone permissions as well as app tracking blocks — and offer the same quality-of-life features such as dark mode, dynamic theming, split-screen multitasking, Picture-in-Picture, and on-device machine learning.

Notably, neither phone receives direct OS updates from Google, meaning both rely on their respective manufacturers to deliver Android patches and upgrades — a consideration worth keeping in mind for long-term software support, though it is equally relevant to both devices here.

This category is an unambiguous tie. No differentiator exists between these two phones based on the provided data, and a user's OS experience will be functionally identical regardless of which device they choose.

Two numbers define this category, and both favor the same device. The Realme P3 Ultra carries a 6000 mAh battery against the CMF Phone 2 Pro's 5000 mAh — a 20% capacity advantage that, all else being equal, translates directly into more screen-on time between charges. For heavy users or those who travel without reliable access to a charger, that extra 1000 mAh is a tangible buffer.

The charging speed gap is even more pronounced. The Realme supports 80W fast charging versus the CMF's 33W, meaning not only does the Realme start with a larger tank, it refills it significantly faster. In practical terms, an 80W charger can typically top up a large battery in well under an hour, while 33W will take considerably longer — a relevant difference during a short break or a rushed morning routine. Neither phone offers wireless charging, so both users are tethered to a cable either way.

The Realme P3 Ultra wins this category outright, combining a larger battery capacity with substantially faster wired charging. It is one of the more decisive advantages across this entire comparison.

Audio is a short but meaningful category here, with one spec separating the two devices. The Realme P3 Ultra features stereo speakers, while the CMF Phone 2 Pro does not. Stereo output uses two physically separated drivers to create a sense of width and directionality in sound — a noticeable improvement over mono for media consumption, gaming, and video calls, particularly when the phone is held in landscape orientation.

Everything else in this group is identical: neither phone includes a 3.5mm headphone jack, and neither supports high-resolution wireless audio codecs like LDAC or aptX Lossless. Users of both devices who prioritize audio quality will need to rely on Bluetooth headphones or a USB-C adapter for wired listening.

The Realme P3 Ultra takes a clear edge here. Stereo speakers are a practical, everyday advantage for anyone who regularly watches content or plays games without headphones — and it is the only differentiator this category offers.

Connectivity is broadly well-matched between these two devices, with both supporting 5G, Wi-Fi 6, NFC, dual SIM, USB-C, and an identical sensor suite including GPS, gyroscope, accelerometer, and compass. The Realme edges ahead with Bluetooth 5.4 versus the CMF's 5.3 — a minor generational step that brings marginal improvements in connection stability and energy efficiency, though the real-world difference for most users will be imperceptible.

The most practically significant differentiator here is storage expandability. The CMF Phone 2 Pro includes a microSD card slot, while the Realme P3 Ultra does not. For users who store large volumes of photos, videos, or offline media, this is a meaningful advantage — it allows the CMF's base 256GB to be supplemented cheaply without relying on cloud storage or upgrading to a higher internal storage tier.

This category ends in a near-tie with device-specific trade-offs. The Realme's marginally newer Bluetooth version is unlikely to influence a purchase decision, but the CMF's expandable storage is a concrete, practical benefit for storage-conscious users. On balance, the CMF Phone 2 Pro holds a slight real-world edge here.

The Miscellaneous category offers no basis for differentiation whatsoever. Every data point — from the presence of a video light to the absence of sapphire glass, a curved display, or an e-paper panel — is identical across the CMF Phone 2 Pro and the Realme P3 Ultra.

This is a complete tie, and neither device gains or concedes anything here. Users can set this category aside entirely when weighing up their decision between these two phones.
