OnePlus Ace 5 Racing VS Xiaomi Redmi Turbo 4 Pro

The most meaningful difference in this category is water protection. The Xiaomi Redmi Turbo 4 Pro is rated as waterproof, while the OnePlus Ace 5 Racing is merely water resistant. In practical terms, waterproof implies a more rigorous, typically standardized level of protection — capable of handling submersion — whereas water resistant only covers splashes and brief exposure. For users who frequently use their phone outdoors or near water, this distinction matters considerably.

On physical dimensions, the two devices tell a nuanced story. The Ace 5 Racing is notably lighter at 199 g versus 219 g for the Turbo 4 Pro — a 20 g difference that is perceptible during extended one-handed use or long sessions. The Turbo 4 Pro, however, is marginally thinner at 8 mm compared to 8.3 mm, and its slightly smaller overall volume (101.64 cm³ vs 103.20 cm³) means it packs its extra weight into a fractionally more compact frame. Width and height are nearly identical across both devices, so neither has a clear ergonomic footprint advantage.

Neither phone features a rugged build or a foldable form factor, so both target the same mainstream slab design audience. Overall, the edge here is split: the Ace 5 Racing wins on weight, making it the more comfortable daily carry, while the Turbo 4 Pro wins on water protection, offering meaningfully stronger environmental durability. Which advantage matters more depends entirely on the user's priorities.

Both phones use OLED/AMOLED panels with a 120Hz refresh rate, so the baseline viewing experience — deep blacks, vibrant colors, smooth scrolling — is shared. The real separation emerges in resolution and sharpness. The Turbo 4 Pro outputs a 1280 x 2772 px image on its 6.83″ screen, yielding a pixel density of 447 ppi, while the Ace 5 Racing delivers 1080 x 2392 px across a 6.77″ panel at 388 ppi. That 59 ppi gap is genuinely visible — text appears crisper and fine detail in photos or video is more defined on the Turbo 4 Pro, particularly at typical viewing distances.

The HDR story also favors the Turbo 4 Pro. While both support HDR10, only the Turbo 4 Pro adds HDR10+ and Dolby Vision — the latter being particularly relevant for streaming platforms like Netflix and Apple TV+, where Dolby Vision content is widely available. Combined with its Always-On Display feature, the Turbo 4 Pro offers a richer, more feature-complete screen package for media-focused users.

The Ace 5 Racing counters with one meaningful advantage: branded damage-resistant glass, which the Turbo 4 Pro lacks. For users who skip screen protectors, this is a tangible long-term durability benefit. That said, on pure display performance, the Turbo 4 Pro holds a clear edge — its higher resolution, superior HDR support, and Always-On Display collectively make it the stronger choice for anyone who prioritizes screen quality.

Under the hood, these two phones take very different silicon paths. The OnePlus Ace 5 Racing runs on the MediaTek Dimensity 9400e, while the Turbo 4 Pro uses the Qualcomm Snapdragon 8s Gen 4 — both fabbed on a 4 nm process, but the benchmarks tell a clear story. The Ace 5 Racing scores 7547 in Geekbench 6 multi-core and 2302 single-core, versus 6880 and 2154 respectively for the Turbo 4 Pro. These are not marginal gaps — the Ace 5 Racing holds a roughly 10% CPU advantage across both metrics, which translates to faster app launches, snappier multitasking, and more headroom in sustained workloads.

The GPU picture mirrors this. The Ace 5 Racing's Arm Immortalis-G720 MC12 clocks at 1300 MHz, compared to the Turbo 4 Pro's Adreno 825 at 1150 MHz. More telling still is RAM bandwidth: the Ace 5 Racing's memory runs at 8533 MHz versus just 4800 MHz on the Turbo 4 Pro — nearly double — which meaningfully reduces data-transfer bottlenecks in GPU-heavy tasks like gaming and video processing. Both devices max out at 24 GB RAM and share identical memory bandwidth ceilings on paper, but the higher RAM clock on the Ace 5 Racing gives it a real-world throughput edge.

The one area where the Turbo 4 Pro pulls decisively ahead is storage: it offers up to 1024 GB of internal storage versus 512 GB on the Ace 5 Racing — a significant advantage for users with large media libraries or who avoid cloud storage. Everything else being equal, however, the Ace 5 Racing holds the performance edge in this category, with stronger CPU scores, a faster GPU clock, and substantially quicker RAM — making it the more capable device for demanding tasks.

At first glance the camera systems look near-identical — both lead with a 50 MP main sensor, OIS, and 4K @ 60fps video — but the secondary lens reveals a meaningful gap. The Turbo 4 Pro pairs its main camera with an 8 MP secondary shooter, compared to just 2 MP on the Ace 5 Racing. A 2 MP sensor is typically limited to depth-sensing duties, offering little practical imaging value, whereas 8 MP is sufficient for real auxiliary functions like ultrawide or macro capture. For users who rely on versatility across multiple focal scenarios, this difference matters.

The front camera also tilts toward the Turbo 4 Pro: 20 MP with a f/2.2 aperture versus 16 MP at f/2.4 on the Ace 5 Racing. The wider aperture lets in more light, which tends to produce better selfie results in dim conditions — a meaningful advantage for social-media-focused users. Meanwhile, the Ace 5 Racing counters with a 3-LED flash arrangement compared to 2 LEDs on the Turbo 4 Pro, which can improve flash coverage and evenness in low-light stills.

The single most decisive differentiator for enthusiast photographers, however, is RAW shooting — available on the Ace 5 Racing but absent on the Turbo 4 Pro. RAW capture preserves unprocessed sensor data, giving serious photographers full control in post-processing. That said, for the average user, the Turbo 4 Pro's stronger secondary camera and better front shooter are likely more day-to-day relevant. The conclusion is split by use case: the Turbo 4 Pro has the edge for general and selfie photography, while the Ace 5 Racing is the pick for manual and enthusiast shooting thanks to RAW support.

This is a rare case of a complete dead heat. Both the OnePlus Ace 5 Racing and the Xiaomi Redmi Turbo 4 Pro ship with Android 15 and share an identical feature set across every tracked specification in this category — from privacy controls like location and camera/microphone management, to productivity features like split-screen, Picture-in-Picture, and widgets, to quality-of-life additions like dynamic theming, extra dim mode, and on-device machine learning.

Neither phone receives direct OS updates — meaning both rely on their respective manufacturers to push Android updates rather than receiving them straight from Google. This is worth noting for users who prioritize long-term software support, as update cadence will depend entirely on OnePlus and Xiaomi's individual track records, which fall outside the scope of these specs.

With no differentiating data point across the entire group, this category is a complete tie. Buyers should not factor the operating system spec sheet into their decision between these two devices — the choice will come down to the differences identified in other categories.

Battery capacity is one area where both phones genuinely impress — but they diverge in a classic endurance-versus-speed tradeoff. The Xiaomi Redmi Turbo 4 Pro edges ahead with a 7550 mAh cell versus 7000 mAh on the OnePlus Ace 5 Racing. A 550 mAh difference at this capacity tier is modest in percentage terms, but on devices already built for multi-day use, it can translate to a meaningful extra buffer — particularly for heavy users who push their phone through long travel days or demanding workloads without access to a charger.

The Ace 5 Racing hits back on charging speed: at 100W, it charges noticeably faster than the Turbo 4 Pro's 90W. While 10W may sound minor, at these wattages it can shave several minutes off a full charge cycle — a real convenience factor for users who rely on quick top-ups rather than overnight charging. Neither phone supports wireless charging, so both require a cable regardless.

The verdict here depends on usage pattern. Users who prioritize squeezing out maximum screen-on time will appreciate the Turbo 4 Pro's larger battery, while those who want the fastest possible recharge will favor the Ace 5 Racing's 100W charging. As a tiebreaker, the raw capacity advantage of the Turbo 4 Pro is arguably more impactful for most users — a bigger tank reduces range anxiety in a way that 10 extra watts of charging speed does not fully compensate for.

Shared ground dominates this category: both phones drop the 3.5mm headphone jack, feature stereo speakers, and support aptX for improved Bluetooth audio quality over standard SBC. Neither device offers LDAC, Sony's high-resolution wireless codec, which means neither can stream at the highest Bluetooth audio bitrates available on Android.

The sole differentiator is that the OnePlus Ace 5 Racing adds aptX HD support on top of standard aptX. aptX HD enables 24-bit audio transmission over Bluetooth at higher bitrates than standard aptX, delivering a closer-to-lossless experience when paired with compatible headphones. For users who invest in quality wireless headphones that support aptX HD, this is a tangible benefit — though it requires the headphones themselves to also support the codec to make any difference.

The Ace 5 Racing holds a narrow but clear edge in this category purely on the strength of aptX HD. For casual listeners, the gap is unlikely to be noticeable. For audiophiles using compatible gear, however, it is the only meaningful codec advantage available in this comparison, and it goes exclusively to the Ace 5 Racing.

Across most of this category, the two phones are evenly matched — both support 5G, Wi-Fi 7, Bluetooth 5.4, NFC, dual SIM, USB Type-C, and an identical sensor suite including gyroscope, compass, accelerometer, and infrared. For everyday connectivity tasks, users of either device will have access to the same generation of wireless technology.

The standout differentiator is cellular throughput. The OnePlus Ace 5 Racing supports download speeds up to 10,000 Mbits/s and upload up to 7,000 Mbits/s, compared to 4,200 Mbits/s down and 3,500 Mbits/s up on the Turbo 4 Pro — more than double in both directions. In practice, real-world 5G speeds are constrained by carrier infrastructure and rarely approach these theoretical peaks, but higher modem ceilings do translate to better performance in congested networks and in areas with strong mmWave or advanced 5G coverage. For users in markets with cutting-edge 5G deployment, this gap is meaningful.

With everything else tied, the Ace 5 Racing holds a clear edge in this category on the strength of its substantially higher cellular modem speeds. It is a spec that will not matter to everyone, but for users who push mobile data hard — streaming, hotspot sharing, or operating in dense urban 5G environments — the Ace 5 Racing's modem headroom offers a genuine practical advantage.

The miscellaneous category offers no basis for differentiation. The OnePlus Ace 5 Racing and the Xiaomi Redmi Turbo 4 Pro share an identical profile across every tracked spec here: both include a video light, and neither features a sapphire glass display, a curved display, or an e-paper display. There is simply nothing in this data set that separates them.

This is a complete tie. Buyers should weight this category as a non-factor in their decision and refer to the differences identified across other spec groups instead.
