Realme GT 7 Pro Racing VS Samsung Galaxy S25 Ultra

In terms of overall form factor, these two flagships are remarkably close. Both weigh exactly 218 g and share nearly identical footprints — the Galaxy S25 Ultra is fractionally taller and wider, while the Realme GT 7 Pro Racing is marginally thicker at 8.6 mm versus the S25 Ultra's slimmer 8.2 mm. That 0.4 mm difference is barely perceptible in isolation, but combined with the S25 Ultra's lower total volume (103.59 cm³ vs 107.47 cm³), the Samsung feels slightly more compact and refined in the hand despite having a larger footprint on paper.

Where the Realme earns a genuine edge is water resistance. Its IP69 rating goes beyond the S25 Ultra's IP68 by adding certified protection against high-pressure, high-temperature water jets — a scenario where IP68 offers no guarantee. In everyday life most users will never encounter that condition, but IP69 represents a meaningfully higher engineering standard, offering greater peace of mind in demanding environments like kitchens, workshops, or outdoor use.

Overall, neither phone has a rugged build or a foldable design, so the comparison comes down to two trade-offs: the S25 Ultra is slightly slimmer and more volume-efficient, while the Realme GT 7 Pro Racing holds a clear advantage in water resistance certification. For users who prioritize a sleeker profile, the Samsung Galaxy S25 Ultra has the edge; for those who value superior ingress protection, the Realme GT 7 Pro Racing wins outright in this category.

Both phones use OLED/AMOLED panels with a 120Hz refresh rate, but the Samsung Galaxy S25 Ultra pulls ahead on raw visual fidelity. Its larger 6.9″ screen, higher 1440 x 3120 resolution, and 498 ppi pixel density result in noticeably sharper text and finer detail than the Realme GT 7 Pro Racing's 450 ppi — a difference that becomes visible when reading small text or viewing high-resolution images up close. The S25 Ultra also ships with branded damage-resistant glass and an Always-On Display, two practical daily-use advantages the Realme lacks entirely.

The Realme, however, throws a surprising punch in one area: contrast. Its stated contrast ratio of 6,000,000:1 is double the S25 Ultra's 3,000,000:1, which on paper suggests deeper blacks and more dramatic shadow detail. It also supports Dolby Vision, which the S25 Ultra does not, making it the better companion for Dolby Vision-mastered streaming content on platforms like Apple TV+ or Netflix. The S25 Ultra counters with HDR10+ support shared by both devices, so the format advantage ultimately depends on which streaming ecosystem the user frequents.

On balance, the Samsung Galaxy S25 Ultra holds the stronger overall display position — its higher resolution, greater sharpness, protective glass, and Always-On functionality represent tangible real-world advantages for most users. The Realme GT 7 Pro Racing's contrast ratio and Dolby Vision support are meaningful but more situational perks, making it a display winner only in very specific viewing scenarios.

At the silicon level, this is a mirror match: both phones run the Qualcomm Snapdragon 8 Elite on a 3 nm process, with identical Adreno 830 GPUs, memory bandwidth, cache hierarchy, and TDP. Yet the benchmark results tell an interesting story. The Realme GT 7 Pro Racing scores a significantly higher 2,739,727 on AnTuTu versus the S25 Ultra's 2,207,809 — a gap of roughly 24% — while also leading in both Geekbench 6 single-core (3,234 vs 3,057) and multi-core (10,059 vs 9,846) results. This is notable given that the S25 Ultra's prime cores are clocked slightly higher at 4.47 GHz versus the Realme's 4.32 GHz, suggesting the Realme benefits from more aggressive thermal or power tuning that translates to better sustained performance in benchmark conditions.

The RAM and storage trade-off is the other defining split. The Realme ships with 16 GB of RAM compared to the S25 Ultra's 12 GB, which gives it a practical edge in heavy multitasking, keeping more apps resident in memory simultaneously. The Samsung counters with a decisive storage advantage — 1 TB of internal storage versus the Realme's 512 GB — making it the better fit for users who accumulate large media libraries or shoot extensive 4K/8K video without relying on cloud storage.

The Realme GT 7 Pro Racing holds the clear performance edge in this group: higher benchmark scores across all three metrics and more RAM for multitasking give it an advantage in raw compute. The S25 Ultra's doubled storage capacity is a meaningful practical differentiator, but it doesn't offset the performance gap — so if processing power and memory headroom are the priority, the Realme wins outright here.

The camera gap between these two phones is substantial. The Realme GT 7 Pro Racing offers a dual rear setup with a 50 MP primary and 8 MP secondary lens, while the Samsung Galaxy S25 Ultra fields a four-lens system headlined by a 200 MP main sensor alongside 50 MP, 50 MP, and 10 MP supporting cameras. More lenses means more versatility — the S25 Ultra can cover a wider range of focal lengths and shooting scenarios natively, and its 5x optical zoom versus the Realme's 3x delivers meaningfully longer reach without digital quality loss. For users who frequently shoot distant subjects — wildlife, sports, concerts — that zoom advantage is felt immediately.

Video capabilities also diverge sharply. The S25 Ultra records up to 4320p (8K) at 30 fps, compared to the Realme's ceiling of 2160p (4K) at 60 fps. The S25 Ultra additionally supports HDR10 video recording and benefits from a BSI sensor, which improves light capture efficiency — an advantage the Realme's CMOS-only setup lacks. The S25 Ultra also gains laser autofocus and manual shutter speed control, two features absent on the Realme that matter most to users who shoot in challenging light or want precise exposure control.

The Samsung Galaxy S25 Ultra wins this category decisively. Its quad-camera array, higher-resolution main sensor, greater optical zoom range, 8K video, BSI sensor, and broader manual controls give it a comprehensive advantage at virtually every level of camera use. The Realme is a capable shooter for everyday needs, but it cannot match the S25 Ultra's depth, flexibility, or ceiling.

Running the same Android 15 base, these two phones share an overwhelming majority of software features — from split-screen multitasking and picture-in-picture to dynamic theming, offline voice recognition, and a comprehensive suite of privacy controls. For most day-to-day software needs, users of either device will find themselves on largely equal footing.

The differences, while few, are genuinely useful. The Samsung Galaxy S25 Ultra adds cross-site tracking blocking, Wi-Fi password sharing, focus modes, and crucially, the ability to be used as a PC — a desktop-mode capability that lets users connect the phone to a monitor and work in a more traditional computing environment. That last feature in particular sets the S25 Ultra apart as a productivity tool beyond the phone itself, appealing to users who want to consolidate their devices. The Realme GT 7 Pro Racing offers none of these four extras.

The Samsung Galaxy S25 Ultra takes a narrow but clear edge in this category. The shared feature set is extensive, so neither phone feels lacking for typical use — but the S25 Ultra's additional productivity and privacy tools, especially desktop PC mode, represent real-world functionality the Realme simply does not provide.

Battery capacity is where the Realme GT 7 Pro Racing makes one of its most compelling statements. Its 6500 mAh cell is 30% larger than the Samsung Galaxy S25 Ultra's 5000 mAh — a difference significant enough to translate into meaningfully longer usage between charges, particularly for heavy users who stream, game, or stay away from an outlet for extended periods. Paired with a bundled 120W fast charger, the Realme can also replenish that larger battery dramatically faster than the S25 Ultra's 45W wired speed — a combination of high capacity and rapid refill that is rare at any price point.

The Samsung's key differentiator here is wireless charging, a convenience feature the Realme lacks entirely. For users embedded in a wireless charging ecosystem — desk pads, car mounts, bedside chargers — this is a genuine lifestyle advantage that enables effortless top-ups throughout the day. It's also worth noting the S25 Ultra does not include a charger in the box, meaning buyers must source one separately to take advantage of its 45W wired speed.

The Realme GT 7 Pro Racing wins this category clearly. A larger battery, dramatically faster wired charging, and an included charger in the box give it a practical power advantage that most users will notice daily. The S25 Ultra's wireless charging support is a meaningful convenience perk, but it doesn't offset the Realme's substantial leads in both capacity and charging speed.

Stripped of a 3.5mm headphone jack and equipped with stereo speakers, both phones share the same baseline audio hardware setup — meaning wired headphone users will need an adapter or USB-C earphones regardless of which device they choose. For speaker listening, neither holds a documented advantage from these specs alone.

Where the Samsung Galaxy S25 Ultra pulls ahead is wireless audio quality. It supports both aptX and aptX HD — Qualcomm's codecs for high-quality Bluetooth audio — as well as LDAC, Sony's high-resolution wireless codec capable of transmitting up to three times the data of standard Bluetooth audio. Together, these three codecs give S25 Ultra users access to near-lossless wireless listening when paired with compatible headphones, a meaningful advantage for audiophiles. The Realme GT 7 Pro Racing supports none of these codecs, meaning Bluetooth audio is limited to standard SBC or AAC quality.

The Samsung Galaxy S25 Ultra is the clear winner here. The addition of LDAC, aptX, and aptX HD meaningfully elevates the wireless listening experience for users with high-quality Bluetooth headphones, while the Realme offers no equivalent — making this one of the more lopsided category outcomes in this comparison for audio-conscious buyers.

The connectivity foundations are nearly identical: both phones offer 5G, Wi-Fi 7, Bluetooth 5.4, NFC, USB-C, dual SIM, and matching peak download and upload speeds. For the vast majority of users, this shared baseline will cover every everyday connectivity need without distinction. The Samsung Galaxy S25 Ultra does add Wi-Fi 6E support, which opens up the less congested 6 GHz band for faster, more stable connections in dense environments — a useful but situational upgrade that requires a compatible Wi-Fi 6E router to realize.

Beyond radio connectivity, the S25 Ultra separates itself with several notable extras. It supports dual eSIM alongside two physical SIM slots, offering greater carrier flexibility without sacrificing a physical card slot — particularly valuable for frequent travelers. It also includes a barometer for altitude and weather sensing, ANT+ support for connecting fitness and sports equipment, and comes with a stylus, which adds a precision input method the Realme GT 7 Pro Racing has no equivalent for.

The Samsung Galaxy S25 Ultra wins this category. While the shared connectivity specs are strong on both sides, the S25 Ultra's eSIM support, Wi-Fi 6E, barometer, ANT+ compatibility, and bundled stylus collectively represent a broader, more versatile feature set — especially for power users, fitness enthusiasts, and those who value precision note-taking or annotation directly on their device.

The miscellaneous specs for these two phones are an exact match across every data point provided. Both feature a video light, neither uses sapphire glass, neither has a curved or e-paper display. There is simply nothing in this group that differentiates one device from the other.

This is a complete tie — no edge can be awarded to either the Realme GT 7 Pro Racing or the Samsung Galaxy S25 Ultra based solely on the data available here. Users should weigh the outcomes of the other specification groups to inform their overall decision.
