This is my detailed review of the Lenovo Slim 7i Pro X. It’s the European variant of the laptop, and it is sold here as the Lenovo Yoga Slim 7i Pro X.
If you’re shopping for a
powerful compact laptop, you’re most likely already familiar with this mid-2022 Slim 7 Pro X series, which has been available in stores for a few months now and has already been highly praised by many media outlets. This is also a follow-up of the 2022 Yoga Slim Pro 14, which I’ve reviewed in the past.
I’ve been using this Pro X unit for the last week or so, and it’s a retail model with mature software at this point. This is the Intel variant, the i7-12700H + RTX 3050 configuration, as Lenovo offers an AMD model as well. Most of my findings apply to both variants, but the AMD version differs in performance, efficiency, and a few other small details, so you’ll want to read a dedicated review of that AMD model if that’s what you’re primarily interested in.
Down below we’ll get in-depth on all the important aspects that you should be aware of when shopping for one of these.
For the most part, this lives up to the hype and is a c
ompetitive all-purpose 14-inch laptop. It’s not as powerful as a Blade 14 or a Zephyrus G14, but it’s smaller, lighter, and more affordable, while still checking most of the aspects that I’d want in this sort of laptop, except perhaps for all-day battery life when used unplugged and some good speakers.

Design and construction
Compared to the previous Yoga Slim Pro generation, Lenovo have updated the overall design and ergonomics on this mid-2022 series, which is now a little larger and heavier, as a result of including a bigger display, a larger battery, and the updated chassis.
In all fairness, though, this is still compact for its size and capabilities, as you can tell from the narrow bezels around the screen and its slim profile. It does weigh around 1.5 kilos, though, so is not
as lightweight as other options.
It’s also built really well, with a study main chassis and display, and without any noticeable flex or creaks with everyday use. Overall, this feels much like a premium laptop, which hasn’t been the case with the past generations.
The dark-gray finishing also does a good job hiding smudges and fingerprints, although it’s perhaps not the most beautiful color. As a practical utilitarian design, though, this is hard to fault in any way.
My only complaint is of the front lip that’s a bit sharp on the wrists, despite the fact that the rounded edges on the main chassis might suggest otherwise on a first glance. Even so, with the low profile and spacious armrest, your hands will rarely get in contact with those edges.
This detail aside, there’s nothing to knit about. The rubber feet on the bottom offer good grip on the desk, the screen is held in place by two smooth hinges that allow it to lean back to 180 degrees, and there are no annoying lights in the line of sight. Branding is also kept to a minimum, as long as you peel off the stickers plastered on the armrest and to the right side of the clickpad.
Other aspects worth mentioning here are the updated camera with IR support placed on the top screen bezel, the light-sensor placed at the top of the screen as well, the up-firing speakers that are flanking the keyboard, and the IO on the sides.
There are two USB-C ports with Thunderbolt 4 support on the left side, as well as a full-size HDMI port, while on the right there’s a USB-A port, the audio jack, and an eShutter camera knob. This IO should meet most expectations, even if there’s no card reader and no Lock, and the USB-C ports are both placed on the left edge, which means you’re lacking the convenience of plugging this on both sides.
Overall, this Lenovo Yoga Pro X feels like a beefed-up Yoga, much as I’d expect from a Pro model. On the outside, it looks and feels like a grownup premium-tier laptop, without signaling the potential hidden inside. We’ll discuss it further down.
Keyboard and trackpad
This Lenovo Slim Pro X gets a standard Yoga/IdeaPad keyboard, as well as a large clickpad that we weren’t offered in the past.
The keyboard’s layout is standard for this sort of portable Lenovo laptop, with full-sized and spaced keys. The half-sized Up and Down keys are a bit weird, but everything else is where it should be. There’s no extra column of function keys on the right side, as on other 14-inch designs, and that’s why Home/End/PgUp/PgDn are only available as secondaries bound to the arrow keys.
The keycaps are made out of plastic, with a slightly rounded bottom shape, and a little softer to the touch than I recall from the previous Yoga models. Lenovo also went with a dark-grey color for the keycaps, as opposed to the black keycaps used in the past, and they’re better at hiding finger oil over time.
The typing experience is alright. The feedback isn’t as mushy as on past Yoga/IdeaPad keyboards, but still needs time to get used to, as the keys require a very firm press to actuate, so the typing experience is a little odd and fatiguing. Even after typing in several thousands of words on this keyboard, I still struggled to meet my standard speed and accuracy with this one.
The keys are also backlit, with two brightness levels to choose from. The LEDs are bright and fairly uniform. Lenovo also throws in companion LED indicators for Caps Lock and FnLock. The illumination never times out, though, so you need to manually switch the keys off when needed, with Fn + Space.
The clickpad is spacious for a Yoga laptop and felt responsive and accurate with daily use. It still feels like plastic to me (not entirely sure about it?), and it’s still rather flimsy, as it rattles with firmer taps and sounds clunky when clicking the corners.
As for biometrics, there is no finger sensor on this unit, but I do have the IR camera on this unit (it’s optional in some regions) that works well with Windows Hello.
Even more than with the past models, the screen is one of the major selling points of this Lenovo Slim Pro X generation. It’s a 16:10 format with a 14.5-inch high-resolution IPS panel.
However, our variant is the lower-tier panel option, with standard-gamut color coverage, a glossy finish, and without a touch layer – a touch variant is also available in some regions, though. At this point, I’m not sure how the touch/digitizer layer impacts the perceived sharpness, but from what I’m seeing in other reviews, this screen has received high praise in the touch implementations.
Back to our unit, this is a 3K 3072 x 1920 px resolution IPS panel with 120Hz refresh, 400 nits of max brightness, alright blacks and contrast, and only 100% sRGB color coverage.
This is well-balanced for everyday use and workloads, but not ideal for color-accurate work and will struggle in bright office environments or outdoors, due to the limited maximum brightness and the glare of the glossy finishing. I’m not a fan of this kind of glossy non-touch screens. On the other hand, this is very sharp and the format and resolution allow for a multitude of usable scaling options, as well as you’re using modern apps that properly scale with Windows.
Here’s what we got in our tests,
with a X-Rite i1 Display Pro sensor:
Panel HardwareID: Lenovo CSO T3 (MNE507ZA1-1);
Coverage: 97.2% sRGB, 67.2% AdobeRGB, 69.3% DCI P3;
Measured gamma: 2.25;
Max brightness in the middle of the screen: 410.53 cd/m2 on power;
Min brightness in the middle of the screen: 1.44 cd/m2 on power;
Contrast at max brightness: 1272:1;
White point: 6700 K;
Black on max brightness: 0.32 cd/m2;
Response: 35 ms GtG (Source).
The panel came well-calibrated out of the box and proved uniform once further calibrated. I also noticed very little light bleeding around the edges.
Furthermore, PWM modulation is not used at any brightness levels, so flickering is not a concern, and Lenovo allows for some very low brightness levels, making this excellent for those interested in using it in a pitch-black room.
On the other hand, this panel is not ideal for gaming. Sure, it’s 120 Hz refresh, so better than a standard 60Hz panel, but the middling response times translate into ghosting and lag in competitive fast-paced games. Up to you if that aspect is important, or not.
On top of that, this is still only a standard-gamut panel, so not ideal for any color-accurate creative work. This can also be a deal-breaker, given the multitude of high-gamut displays available out there in similar products – most of them are OLEDs, though, which come with their own share of particularities and potential deal-breakers.
Hardware and performance
Our test model is a higher-specced configuration of the Lenovo Yoga Slim 7i Pro X, with an Intel Core i7-12700H processor, 32 GB of LPDDR5-6000 RAM, 1 TB of fast SSD storage, and dual graphics with Iris Xe iGPU and an Nvidia GeForce RTX 3050 dedicated chip.
Disclaimer: Our review unit is a retail model provided by Lenovo for this review, running on the software available as of early December 2022 (BIOS HMCN31WW, Lenovo Vantage 188.8.131.52, Nvidia Game Ready Driver 527.56). This is a mature product with mature software, so little can change with future software updates.
Spec-wise, this is based on the 2022 Intel 12th-gen Alder Lake Core H hardware platform. The Core i7-12700H is a hybrid design with 6 Performance and 8 Efficiency Cores, as well as 20 combined threads. Despite its size, this implementation supplies the CPU with ~55W of sustained power in demanding loads, which is higher than most other portable designs on their top-performance profiles. We’ll get in-depth further down.
Graphics in sustained loads are handled by a dedicated Nvidia RTX 3050 dGPU running at up to 55W on the Extreme Performance profile. Once more, this is higher than most other portable
3050-class implementations. Lenovo also implements a MUX here, with an option for either Regular or Advanced Optimus. I’ve kept the laptop on Advanced Optimus during my time with it.
Our configuration also comes with 32 GB of LPDDR5-6000 memory. The RAM is soldered on the motherboard and non-upgradeable, and 16/32 GB configurations are offered, so make sure to choose the one that best fits your needs.
For storage, Lenovo opted for a mid-tier PCIe gen4 Micron 3400 drive here. There’s a single M.2 2280 slot inside.
It is possible to open up this device to get to the internals, and it’s a fairly simple task, as the back panel is held in place by a few Torx screws, all easily accessible.
Inside you’ll find the SSD slot and the WiFi module, with everything else being soldered. You’ll also notice the large battery, the speakers, and the thermal module.
As far as the software goes, everything can be controlled through the Lenovo Vantage app, which offers access to the power profiles, keyboard customization options, system updates, battery settings, etc. I find this unified implementation one of the better system control apps in this segment – too bad Lenovo aren’t offering this on all their laptops.
There are three performance/thermal profiles to choose from, and you can switch between them by pressing Fn+Q:
Battery Saving – limits the CPU at 15W sustained and keeps the fans mostly idle;
Intelligent Cooling – limits the CPU at 40W sustained, the GPU at 35W sustained, and ramps that fans to ~38 dB at head-level in sustained loads;
Extreme Performance – further bumps the CPU to 55W sustained, the GPU t0 55W sustained, and ramps that fans to ~42 dB at head-level in sustained loads.
I’ve kept my unit on Intelligent Cooling most of the time, and only switched to Extreme Performance for benchmarks and gaming. This latter profile provides a noticeable boost in performance, but with very high associated internal temperatures and louder fans. At the same time, the fans keep idle with daily use on Intelligent Cooling, and very rarely kick-in with heavier multitasking, so this qualifies as a
completely silent computer with everyday activities.
Performance and benchmarks
On to more demanding loads, we start by testing the CPU’s performance in the Cinebench R15 loop test.
On Extreme Performance, the system applies peak PL2 power of ~75W for a brief moment, but then the i7-12700H stabilizes at around 55W of sustained power. Lenovo implements a thermal limit on this power profile, allowing the processor to run at 95C and adjusting the power/frequency based on this limit. That means the laptop will run at higher power in a cooler environment, and at lower power in a hot place. For reference, we test at around 24 degrees Celsius ambient temperature.
The fans spin at around 42 dBA at head level in this mode, which is not a very loud level.
The Intelligent Cooling profile cuts the fans to around 38 dBA and sets a 40W power limit on the CPU. As a result, the CPU now runs cooler at around 83-85 degrees Celsius. The performance takes a dip, though, of around 15% lower than on Extreme Performance.
The laptop is an excellent performer on battery power as well, stabilizing at 40W of power on both the Intelligent Cooling and the Extreme Performance modes. All these are detailed in the following graph and logs.
To put these in perspective, here’s how this i7-12700H implementation fares against a few other Intel/AMD platforms available in other mid-sized laptops. This is one of the better 14-inch CPU implementations available on the market, quieter and more powerful than most other options, and nearly a match for the
Ryzen 9 in the Zephyrus G14, which runs at higher power and at higher noise.
Thus, if you’re looking for powerful multi-core CPU performance in a compact chassis, this Slim 7i Pro X is one of the better options out there.
We then went ahead and further verified our findings with the more taxing Cinebench R23 loop test and in Blender, confirming our above findings.
We then ran the 3DMark CPU profile test.
Finally, we ran our combined CPU+GPU stress tests on this notebook, on the Extreme Performance profile. 3DMark stress runs the same test for 20 times in a loop and looks for performance variation and degradation over time, and this unit was able to pass it with flying colors, which means the performance does not decrease with longer demanding loads, even once the heat builds up.
Next, we ran the entire suite of tests and benchmarks, on the Extreme Performance profile in Vantage the dGPU set on the default Automatic Select mode (Advanced Optimus mode). I also set the scree at FHD+ 1920 x 1200 px resolution for consistency with our other tests, and kept the laptop flat on the desk.

These are some excellent results for a computer of this size.
Intel i9 + RTX 3050Ti version of the ROG Flow Z13 is a similar performer in benchmarks, and that’s the most powerful compact design we’ve tested so far. Furthermore, this Yoga Pro X scores higher than the i7 + RTX 3050Ti configuration of the popular Dell XPS 15, or other powerful 14-inches such as the Asus ZenBook 14X Space Edition or the Asus VivoBook Pro 14X.
Unfortunately, I haven’t reviewed the latest Acer Swift X 14 for a proper comparison, as that’s perhaps the closest rival to this Pro X model. I do expect the Lenovo to have an edge, based on its power settings and my experience with the past
Acer Swift X models.
At the same time, there are a handful of more powerful 14-inch laptops out there, such as the Acer Predator Triton 300, the Asus ROG Zephyrus G14, the Alienware X14, or the Razer Blade 14, but those are also thicker, heavier, and much more expensive products.
With that out of the way, I must also add that while this Yoga 7i Pro X doesn’t run very noisy on the Extreme Performance mode, the internal components do heat up, with the CPU often running at the 95 C thermal limit, and the GPU running at around 85 degrees Celsius or even higher in sustained loads.
Thus, if you preffer cooler internals and a quieter experience, the Intelligent Cooling mode on this laptop is worth a try. The components run at 70-85 degrees Celsius in sustained loads on this mode, and the fans don’t go over 38 dAb, compared to temperatures in the 80s and 90s and fan noise of 42 dBA on the Extreme Performance mode.
Here are some benchmark results on this mode.
3DMark 13 – Fire Strike: 8901 (Graphics – 9521, Physics – 25255, Combined – 3619);

The CPU performance takes a 10-15% dip in longer sustained loads, and the GPU runs at about 80% of its capabilities on Extreme. These are still competitive results for this sort of laptop, and it’s up to you whether they’re worth it for what you’re gaining in noise fan and especially in internal temperatures. With daily use, the differences between the two profiles are minimal.
This Slim 7i Pro X is not necessarily a gaming laptop, but I do expect many of you to game on it at least occasionally, so we’re going to take a deeper dive into its gaming abilities in this section.
For starters, here’s what we got on Ultra settings, with the screen at FHD+ 1920 x 1200 px resolution (as gaming at higher res would prove challenging for an RTX 3050 dGPU).

Older titles are able to run just fine, but modern AAA titles dip under the 60 fps limit and will require you to trim down the graphics settings.
Furthermore, the fps differences between the Extreme and Performance profiles are quite significant, due to the difference in GPU power between the two modes. We’ll get in-depth further down, as there are reasons to consider the Intelligent Cooling profile for longer gaming sessions, despite the lower framerates.
Nonetheless, if you’re going to game on this mini-computer, I’d recommend trimming down the details and keeping the resolution at FHD+ to properly benefit from the screen’s 16:10 aspect ratio.
Here’s what we got on Medium settings at FHD+ resolution, in comparison to a few other portable 13-15 inch devices.

All the tested games run well in this case, and the Slim 7i Pro X platform is competitive against other options with similar specs. In fact, it even outmatches most other options due to its higher-power dGPU on the Extreme Performance mode, which runs at 50-55W, while most other 3050/3050Ti portable implementations run in the 40-50W range.
With these out of the way, let’s go through some of the performance logs on each profile.
First off, the Extreme Performance profile, allows the GPU to run at 50-55W sustained power between the tested titles. The fans ramp up to 42 dBA, which is fairly quiet for a top-performance profile; corroborated with the cooling design and high GPU power, all these lead up to high internal GPU temperatures of 82-85 degrees Celsius.
Bumping up the back of the laptop in order to improve the airflow of fresh air into the fans allows for a noticeable drop in internal temperatures, of around 3-7 degrees. Hence, I do recommend placing this laptop at least on a raiser stand if you plan to run demanding loads on the Extreme Performance profile.
You could also consider running loads on the Intelligent Cooling mode, which caps the GPU at around 35W of power; this translates into lower temperatures in the 70s Celsius, despite the fact that the fans are spinning quieter, at 38 dBA. You will have to accept a 15-25% drop in framerates on this profile, though.
Finally, this laptop performs well when unplugged, averaging 25W of sustained GPU power in Witcher 3. It doesn’t match the performance possible with the laptop plugged in, but still offers a usable gaming experience, for an hour and a half until the battery runs out.
Noise, Heat, Connectivity, speakers, and others
Lenovo went with a fairly advanced thermal module here. This implements two mid-capacity fans and two long heatpipes that go over both components and connect to the two radiators.
This is fairly similar to the cooling module on the past Slim 7 Pro models, but Lenovo have bumped the power settings for this generation, and that’s translating into the higher CPU/GPU temperatures on the Extreme Performance profile. Regardless, even this mode is manageable if you prop up the laptop on some sort of stand, to mitigate the fact that the fans are slightly choked with the laptop sitting on a flat surface.
I must also mention that the radiators are placed just under the screen with this design, but most of the hot air goes to the back of the laptop and out of the way, so the panel only gets up to mid-30s Celsius, which is perfectly fine and won’t cause any long term issues. For comparison, most other designs with exhausts placed so close to the screen lead to the panel heating up significantly more.
As far as the noise goes, the fans spin at up to 42 dB at head-level on the Extreme Performance and up to 38 dB on Intelligent Cooling, based on load.
On the other hand, with daily use, this Yoga runs completely silent on both the Battery Saver and the Intelligent Cooling modes, with the fans keeping idle most of the time. I haven’t noticed any coil whine or electronic noises on this unit, but that’s no guarantee you won’t experience any on your unit.
As far as external temperatures go, there’s nothing out of ordinary here. The middle of the chassis heats-up with sustained loads on the Extreme Performance profile, but the laptop doesn’t run hotter than I’d expect from this sort of design, and the arrows and WASD regions keep cool at only around 30 degrees Celsius.
*Daily Use – streaming Netflix in EDGE for 30 minutes, Intelligent Cooling Mode, fans at 0-33 dB
*Gaming – playing Witcher 3 for 30 minutes, Extreme Performance Mode, fans at 42 dB
For connectivity, there’s latest gen WiFi 6E and Bluetooth 5.1 with a Intel AX211 module on this unit. It performed well with our setup and the signal and performance remained strong at 30 feet, with obstacles in between. As far as I can tell, the AMD variants of this laptop ship with Realtek modules, which can sometimes have issues when reconnecting to the Internet after resuming the laptop from sleep.
Audio is handled by a set of stereo speakers that fire through the grills on the left and right sides of the keyboard. They’re not loud (up to 72-73 dBA in our tests) and not much in quality either, but they’re a slight upgrade from the bottom speakers on the previous Yoga Slim Pro generation.
Finally, Lenovo have updated the camera on this series, implementing a 2MPx FHD shooter at the top of the screen, with a wider angle and IR functionality. This camera is alright for occasional calls, especially in a well-lit environment. Microphones are also placed at the top of the screen, and they’re OK for calls as well.
There’s a 70 Wh battery inside this Yoga Slim 7i Pro X series, larger than on the previous model and on par with what the competition offers in their performance 14-inch notebooks.
Here’s what we got on this unit, with the screen set at around 120-nits (60% brightness) and running at 120 Hz.
11 W (~6+ h of use) – text editing in Google Drive, Best Battery Mode, screen at 60%, Wi-Fi ON;
12.5 W (5+ h of use) – 1080p fullscreen video on Youtube in Edge, Best Battery Mode, screen at 60%, Wi-Fi ON;
11 W (6+ h of use) – Netflix fullscreen in Edge, Best Battery Mode, screen at 60%, Wi-Fi ON;
15 W (~4-5 h of use) – browsing in Edge, Intelligent Cooling Mode, screen at 60%, Wi-Fi ON;
40 W (~1.5 h of use) – gaming – Witcher 3, Extreme Performance Mode, screen at 60%, Wi-Fi ON.
There’s a Dynamic refresh mode available in the Display Settings, which should automatically switch between 60/120 Hz refresh. However, I ran some tests with the screen manually set to 120 and 60 Hz, to properly document the differences in efficiency between the two refresh modes. BTW, Fn+R doesn’t work for switching between modes, so I had to change things manually in the settings.
8.5 W (8+ h of use) – screen at 60 Hz, 1080p fullscreen video on Youtube in Edge, Best Battery Mode, screen at 60%, Wi-Fi ON;
7.5 W (9+ h of use) – screen at 60 Hz, Netflix fullscreen in Edge, Best Battery Mode, screen at 60%, Wi-Fi ON.
Switching to 60 Hz makes a noticeable difference with basic activities. For daily use, the Dynamic refresh mode should handle things without requiring any fiddling with the settings.
The laptop ships with a 100W charger that plugs in via USB-C. It’s a dual-piece design with an averagely-sized brick and long and thick cables that add up to about .4 kilos in weight. A full charge takes about 2 hours, with quick charging at the beginning.
Price and availability- Slim 7i Pro X
The Lenovo Yoga Slim 7 Pro X is widely available in stores at the time of this post.
In the US, this Intel i7 + 16 GB RAM + 512 TB SSD + the 3K touch display goes for around $1450 at the time of this update, with further occasional discounts. That’s a fair price, although perhaps a 1 TB SSD would have been welcomed at that level.
At the same time, the AMD version with similar specs, but a Ryzen 7 6800HS processor, goes for under $1300. It’s no match for the CPU capabilities on this Intel model, but it does win in efficiency on battery use, and is a close contender in overall capabilities in daily use and games, so that’s probably the better value choice of the two. There are still reasons why you’d want to opt for the Intel model, though, despite its higher price.
As far as over here in Europe, Lenovo offers the series in a handful of other configurations, including the one we had here, with the non-touch display and 32 GB of RAM. Up to you to choose the one that makes the most sense for your needs, and best fits your budget.

Final thoughts- Lenovo Slim 7i Pro X
This updated Lenovo Yoga Slim 7 Pro X checks a lot of the right boxes in its niche of
powerful compact laptops.
Compared to the
already excellent Slim 7 Pro model of the past, this updated mid-2022 generation is a more refined design with an updated display and slightly different IO and inputs, as well as a significantly more capable performer and longer-lasting on battery use, with the addition of a larger battery inside.
At the same time, this generation is a fair bit more expensive than in the past, and there’s still room to improve certain aspects. Better audio and a wide-gamut panel option would have been appreciated, for instance, and the typing experience isn’t quite down my alley either.
Overall, though, if you need this sort of multi-purpose laptop in a compact 14-inch chassis, the Lenovo Slim 7i Pro X is one of the better such options available in stores today.
