I bought the Lenovo AI Tab LEGION Y700 Wuji.
A high-performance OLED tablet with 5G
The Lenovo AI Tab LEGION Y700 Wuji (also known as 拯救者Y700无极, Y700 無極 or Y700 Infinite) is a high-performance compact tablet powered by the Snapdragon 8 Elite Gen 5 Leading Version, a binned edition of the chip.
It finally moves to an OLED display, and it now supports 5G and GPS positioning as well.
That makes it a high-end tablet that is easy to use outdoors too.
A stylus pen and a folio case are sold as well.
This review was done with the 12GB+256GB model on TB324ZC_CN_OPEN_USER_Q00029.0_A16_ZUXOS_2.0.10.187_ST_260822.

The box includes a manual, a protective case, a charging cable and a charger.
A screen protector comes pre-applied.
Since a clear case is bundled, there is no need to buy one separately.
The charger can put out 68W even on 100V.
Display: easy to see outdoors
The Lenovo AI Tab LEGION Y700 Wuji has an 8.4-inch display with a resolution of 2560 x 1600.
It feels a size smaller than the Lenovo Legion Tab (8.8″, 5) / Y700 Gen 5, which makes it easier to hold.
The subpixel layout is RGB Delta.
With brightness maxed out and a full-white image on screen, an LX-1336B measured a peak of 1146 nits.
It stays readable outdoors in daylight.
It is a unit of brightness: the higher the number, the brighter the screen.
Indoors you generally want around 400–500 nits, and outdoors around 800–1000 nits, or the screen becomes hard to read.
Note that on many devices the maximum is capped unless auto-brightness is turned on.
The refresh rate goes up to 165Hz.
It can be set on a per-app basis.
Measuring the touch sampling rate with Touch Sample Rate Tester, the Movement Rate averaged roughly 390Hz for both single and multi-touch.
It relates to how sensitive the screen is when you touch it.
The higher the number, the more quickly the device tends to react to your touch.
In practice, though, touch latency is not decided by this figure alone; other factors can push the final latency higher.
As a rough guide, a Movement Rate about twice the screen refresh rate is normal, more than three times is high, and gaming phones are often around five to six times.
Touch latency measured with WALT Latency Timer came to 38.3ms in total.
The move to OLED does not seem to have improved this much.
It is the time between touching the screen and the device responding.
The lower the number, the faster the response.
Gaming phones land at around 25ms, while ordinary phones are typically in the 30ms to low-40ms range.
It is Widevine L1, so high-quality streaming works on services such as Amazon Prime Video.
Back: a modest camera bump
The back is two-tone, but the texture is the same smooth finish throughout; only the logo lettering uses a different material and catches slightly under your finger.
The camera is 50MP, and the bump is kept to a minimum.
It weighs 304.3g.
Speakers: strong mids, highs and vocals
The Lenovo AI Tab LEGION Y700 Wuji has stereo speakers.
They get plenty loud, bass is reasonably audible, and vocals tend to sit up front.
Audio latency measured with WALT Latency Timer was 172.2ms with Dolby Atmos (game sound effects) on, and still 136.5ms with it off.
That is on par with budget tablets, so anyone who plays a lot of rhythm games may find it off-putting.
Checking the supported codecs with Bluetooth Codec Changer, it handles AAC / aptX / aptX HD / aptX Adaptive / LDAC.
Ports: two USB-C ports make it easy to live with
The Lenovo AI Tab LEGION Y700 Wuji has two USB Type-C ports.
The one on the long edge is USB 3.2 Gen 2, so it handles fast data transfer and also supports video and audio output over DisplayPort Alt Mode.
There are features to extend battery lifespan, such as stopping charging at 80% or holding the level between 40 and 60%.
Bypass charging can be set to switch on automatically depending on the battery level, or turned on manually.
It powers the system directly instead of charging the battery, which keeps load and heat down.
This is the first Y700 series model to support 5G mobile data.
The supported bands are not published, but at minimum it connects on 4G B3 and B41, and on 5G n41 and n77.
VoLTE calling works without any problems.
The Lenovo AI Tab LEGION Y700 Wuji supports eSIM as well, but unfortunately it only works with a dedicated Chinese plan.
Only one nano SIM fits, so dual-SIM use is not possible.
Even though this is the Chinese version, 6GHz is not restricted, so it can be used just like a global model.
On a Wi-Fi 7 access point using the 6GHz band, it connected at a link speed of around 3459Mbps.
It supports GPS positioning and gets a fix quickly.
Location-based games such as Pokémon GO play without any trouble.
Sensors include an accelerometer, a proximity sensor and a gyroscope.
The power and volume buttons sit near the camera.
Performance: stable FPS at the cost of heat
The Lenovo AI Tab LEGION Y700 Wuji uses the Snapdragon 8 Elite Gen 5 Leading Version, a binned and overclocked chip, so it delivers high performance.
In Geekbench 7, the package-name-spoofed build (which is not affected by vendor boost cheating) scored 3056 single-core and 10799 multi-core, while the normal build scored 3071 single-core and 10750 multi-core.
Since there is no meaningful gap, it does not appear to change performance based on the package name.
More and more manufacturers detect well-known benchmark apps such as AnTuTu by package name and cheat, loosening thermal limits or pinning high clocks so that scores look good only while the benchmark is running.
Because that behaviour differs from normal app use, you end up with devices that benchmark well but do not actually feel any faster in other apps.
Boost behaviour varies from maker to maker, so comparing boosted results is meaningless.
That is why it matters to change the package name so the app looks like an ordinary one, and to get an unboosted, accurate score.
I explain this in detail in this article.
It is a benchmark that puts a number on CPU processing power, the kind used for things like background blur and text processing.
Single-core performance matters for light everyday tasks, while multi-core performance matters for demanding games.
I have collected benchmark results in this article.
In 3DMark’s Wild Life Extreme Stress Test with a spoofed package name, the score went from 7328 to 4458.
Wild Life Extreme uses the Vulkan API and puts a number on GPU performance with graphics rendered at 3840×2160.
A higher score means smoother 3D in games, and high Stability means the device can hold that performance for a long time.
It is only a rough, general indicator for Vulkan API workloads, so it alone does not determine gaming performance.
PCMark Work 3.0 (package-name-spoofed), which measures everyday performance such as working with documents, scored 21275.
That is well above what is needed, so the device seems to keep performance high even in non-gaming apps.
It is as if the tablet goes all-out even on tasks that only need moderate performance, which drives power draw and heat higher than necessary.
It is a benchmark that puts a number on performance in tasks such as web browsing and photo or video editing.
Higher means faster, but the balance with battery drain matters too, so a lower score is not necessarily bad.
Anything above 10000 is plenty.
It uses UFS 4.1 Pro storage and LPDDR5T memory.
In CPDT Benchmark, sequential performance and memory bandwidth in particular were top-tier.
Even with the test file raised to 8GB there was no slowdown from running out of SLC cache, which is an excellent result.
Only 4KB random read was merely average. (At 1GB the variance was a fairly large ±98%, so the 8GB figures look closer to the true performance.)
So it is strong at large sequential reads such as game loading, but not much different from rivals when launching apps or handling lots of small files.
Sequential read and write speeds affect things like copying large files and encoding or decoding video.
Random read and write cover small files, and those speeds are what matter when using apps and games.
Playing the CPU-heavy Genshin Impact in Nod-Krai for 30 minutes in performance mode, with every graphics option at maximum and the frame rate set to 60FPS, Scene measured an average of 60FPS at 76.83mW per FPS.
Battery temperature rose to a peak of about 40.1°C.
The lower the power draw per FPS, the better the power efficiency.
Good efficiency means less battery drain, while poor efficiency means the battery empties fast.
Phones with poor efficiency in games tend to drain heavily in other apps too, so the battery often feels like it disappears quickly.
Average FPS (frame rate) shows how consistently smooth the display stays, and higher is better.
(Strictly speaking, perceived smoothness improves when average FPS is high and there is little of the stutter known as jank.)
Playing the GPU-heavy Honkai: Star Rail for 30 minutes in performance mode, with all graphics options at maximum and the frame rate set to 60FPS, spamming Acheron’s technique in Penacony’s Golden Hour, gave an average of 57.7FPS at 153.73mW per FPS.
SoC temperature averaged 77°C and battery temperature reached 50.3°C, close to a dangerous level, so the poor power efficiency stands out.
Stable frame rates are welcome, but at this temperature the tablet becomes uncomfortable to hold, so dialling the graphics back a little is a good idea.
Game mode offers options such as touch sensitivity, disabling gesture navigation and game sound effects.
Turning on game sound effects adds a little latency, but in exchange the sound gets wider and more forceful.
AI Combo is really just a macro feature; there is no particular AI element to it.
It records your taps and replays them when you press a floating button.
You can set the playback speed and the number of repeats, which makes it handy for automating repetitive tasks.
Genshin Impact supports super resolution and frame interpolation, so it can be played at 120FPS.
Conclusion
The Lenovo AI Tab LEGION Y700 Wuji is a gaming tablet that packs the 8 Elite Gen 5 Leading Version, 5G, GPS and a 165Hz OLED display into a small 8.4-inch body.
It is easy to use outdoors, which makes it a good choice for anyone who plays location-based games or wants to use it for navigation.
It has not even passed Play Protect certification, so a global release seems unlikely, but I am looking forward to what comes next.
