Samsung Galaxy Tab S11 VS ZTE RedMagic Astra

The most immediate design distinction between these two tablets is size and weight. The Samsung Galaxy Tab S11 is a considerably larger device at 253.8 × 165.3 mm and 471 g, placing it firmly in large-tablet territory suited for productivity and media consumption at a desk or on a couch. The ZTE RedMagic Astra, by contrast, measures 207 × 134.2 mm and weighs just 370 g — a 101 g difference that is genuinely noticeable in single-handed or extended use. Ironically, despite being the larger device, the Galaxy Tab S11 is the thinner of the two at 5.5 mm versus the Astra's 6.9 mm, suggesting Samsung has prioritized a premium slim profile even at larger dimensions.

Two spec points stand out as significant differentiators beyond raw dimensions. First, the Galaxy Tab S11 ships with a stylus included, which adds real value for note-taking, sketching, or annotation workflows without any additional purchase. The RedMagic Astra offers no stylus support. Second, and more critically for durability, the Tab S11 carries an IP68 rating, meaning it is fully waterproof under defined conditions, while the Astra's IP54 rating covers only splash and dust resistance — a meaningful gap if the device will be used in kitchens, outdoors, or other humid environments.

Overall, the Galaxy Tab S11 holds a clear design advantage on feature completeness: it includes a stylus and offers superior water protection. The RedMagic Astra counters with a more compact, lighter form factor that may appeal to users prioritizing portability. But in terms of build resilience and out-of-box accessory value, the Tab S11 leads this category decisively.

Both tablets use OLED/AMOLED panels, so the foundational display quality — deep blacks, vivid contrast, accurate colors — is comparable at a technology level. Where they diverge is in how that panel is tuned and sized. The Galaxy Tab S11 offers a larger 11″ screen with a 2560 × 1600 resolution, while the RedMagic Astra packs a 9.06″ panel at 2400 × 1504. Despite its smaller canvas, the Astra actually achieves a higher pixel density — 313 ppi versus 274 ppi — meaning individual pixels are less visible up close, which matters most for reading fine text or detailed artwork at short viewing distances.

The more striking gap is in refresh rate. The Astra's 165Hz panel is exceptionally fluid for a tablet, noticeably smoother than the Tab S11's already capable 120Hz — a difference that gaming and fast-scrolling users will feel in practice. On the other side, the Tab S11 counters with superior content ecosystem support: its HDR10+ certification enables dynamic metadata for scene-by-scene tone mapping in compatible streaming content, a feature entirely absent on the Astra. The Tab S11 also includes an anti-reflection coating, which meaningfully reduces glare under bright indoor or outdoor lighting — the Astra instead relies on branded damage-resistant glass for physical durability, trading glare control for scratch protection.

This category is genuinely split by use case. The RedMagic Astra edges ahead for gaming and close-up content thanks to its sharper pixel density and faster refresh rate. The Galaxy Tab S11 is the stronger media consumption display, offering a larger screen, HDR10+ support, and better real-world usability through its anti-reflection coating. Neither product dominates outright — the right choice depends on whether fluidity and sharpness or screen real estate and content fidelity matter more to the user.

Both tablets are built on 3nm chips, representing the current manufacturing frontier, but they use different silicon. The Galaxy Tab S11 runs on the MediaTek Dimensity 9400 Plus, while the RedMagic Astra deploys the Qualcomm Snapdragon 8 Elite — and the benchmark data reflects a consistent, if not dramatic, edge for the Snapdragon. In Geekbench 6, the Astra scores 10,059 multi-core and 3,234 single-core versus the Tab S11's 8,969 and 2,874 respectively. Single-core performance is particularly relevant for everyday responsiveness — app launches, UI animations, browser rendering — and the Astra leads there by roughly 12%, a difference users are likely to perceive in fluid, snappy interactions.

The GPU picture is more nuanced. The Tab S11's Immortalis G925 runs at a higher clock speed (1300 MHz vs 1100 MHz), while the Astra's Adreno 830 benefits from Qualcomm's mature driver ecosystem, particularly relevant for gaming. Memory architecture also splits in interesting ways: the Astra's 24GB of RAM at the base configuration versus the Tab S11's 12GB is a substantial gap for heavy multitasking or running large AI workloads locally, and the Astra uniquely supports ECC memory, which adds error-correction useful in professional and compute-intensive contexts. The Tab S11 counters with faster RAM at 10,667 MHz, a larger 12MB L3 cache, and critically, an expandable storage slot — the Astra's 1TB of internal storage is fixed.

On raw performance, the RedMagic Astra holds a clear edge: higher benchmark scores, double the RAM, ECC support, and more base storage. The Galaxy Tab S11 partially compensates with expandable storage and a larger cache, but these are secondary considerations. For users who prioritize peak compute power and multitasking headroom, the Astra is the stronger performer in this category.

Rarely in a head-to-head comparison are two camera systems this closely matched. Both the Galaxy Tab S11 and the RedMagic Astra feature a 13MP main camera capable of 4K video at 30fps, identical flash configurations, and an equivalent manual controls suite — ISO, white balance, focus, and exposure are all present on both. Neither offers optical zoom or optical image stabilization, and both share the same slow-motion and continuous autofocus capabilities. For a spec category that often separates devices, the data here paints a picture of near-total parity.

The sole differentiator across the entire spec set is that the RedMagic Astra supports in-camera panorama shooting, while the Galaxy Tab S11 does not. In practical terms, panorama is a convenience feature rather than a professional capability — useful for capturing wide interior spaces or landscapes — but it is the only functional advantage either device holds over the other based on the provided data.

This category is essentially a tie, with a marginal nod to the RedMagic Astra solely for its panorama support. Users making a decision based on camera capability alone will find no meaningful distinction between these two tablets — both are similarly equipped, and neither positions its camera as a primary selling point.

The audio specs for these two tablets are identical across every data point provided. Both feature stereo speakers, neither includes a 3.5mm headphone jack, and both omit any advanced Bluetooth audio codec support — no aptX, LDAC, or any of their variants. For wired audio users, the absence of a headphone jack on both devices means relying on USB-C adapters or Bluetooth headphones.

The lack of high-resolution wireless codecs like LDAC or aptX HD is worth noting for audiophiles considering wireless listening. Without these codecs, Bluetooth audio is limited to standard SBC or AAC compression, which is adequate for casual use but falls short of the fidelity that premium wireless headphones are capable of delivering. That said, this is a shared limitation, not a differentiator.

This category is a complete tie — the spec data reveals no distinction whatsoever between the Galaxy Tab S11 and the RedMagic Astra in audio configuration. Buyers who consider audio quality a priority should look to third-party reviews of speaker output and factor in their preferred headphone setup, as the specification sheet offers no basis for choosing one over the other here.

Battery capacity is nearly indistinguishable between these two tablets. The Galaxy Tab S11 carries an 8400 mAh cell versus the RedMagic Astra's 8200 mAh — a difference of just 200 mAh, or roughly 2.4%. In real-world usage, a gap this small is unlikely to translate into any perceptible difference in screen-on time, and will easily be swallowed by variables like brightness settings, workload intensity, and background activity.

Beyond raw capacity, the remaining specs are identical: both support fast charging, neither offers wireless charging, and both have sealed, non-removable batteries. The absence of wireless charging on both is a shared limitation worth flagging for users who rely on charging pads. Fast charging support on both means topping up from low levels remains convenient, though the actual wattage supported is not specified in the provided data.

This category is effectively a tie. The Galaxy Tab S11's marginally larger battery offers no practical advantage given the negligible size difference. Neither device distinguishes itself here, and battery life in practice will be determined far more by software efficiency and screen-on demands than by this 200 mAh gap.

Connectivity is where these two tablets diverge most meaningfully. The Galaxy Tab S11 includes a cellular module with 5G support, while the RedMagic Astra is a Wi-Fi-only device — a fundamental distinction for users who need connectivity away from known networks. Paired with that, the Tab S11 also supports Wi-Fi 6E, extending into the 6GHz band for lower congestion and higher throughput in dense environments, whereas the Astra tops out at Wi-Fi 6. Interestingly, the Astra lists a higher theoretical peak download speed of 10,000 Mbits/s versus the Tab S11's 7,300 Mbits/s, but this figure applies only under optimal Wi-Fi conditions and does not offset the absence of mobile data connectivity in real-world away-from-home scenarios.

Location capability is another area where the Tab S11 pulls ahead. It includes GPS and Galileo satellite support, enabling accurate standalone positioning — useful for navigation, location-tagged media, and map apps. The Astra lacks both, which limits its location awareness to network-based approximations. For a device without cellular connectivity, the absence of GPS further constrains its utility in mobile or outdoor contexts.

Software features and remaining connectivity specs — Bluetooth 5.4, USB 3.2, fingerprint scanner, gyroscope, and a near-identical privacy and multitasking feature set — are matched across both devices. The verdict in this category is a clear win for the Galaxy Tab S11, which offers a materially broader connectivity profile through 5G, Wi-Fi 6E, and GPS. The Astra is a capable Wi-Fi tablet, but users who need their device to function independently of a router will find it significantly more limited.

The miscellaneous spec group for these two tablets contains just two data points, and both are identical. The Galaxy Tab S11 and the RedMagic Astra each use DDR5 memory and both support multithreading. DDR5 represents the current generation of memory technology, offering improved bandwidth and power efficiency over DDR4 — a baseline that both devices share equally.

This category is a complete tie. There is no differentiator in the provided data, and neither device holds any advantage over the other on these two specifications.
