Lenovo ThinkPad T14 Gen 4 (AMD) review – Comfort Over Raw Power
We were very impressed while testing the Intel-based ThinkPad T14 Gen 4. It’s time to see how good its AMD sibling is. Under the hood, you’ll find a decent thermal solution that cools a Zen 4 processor with integrated graphics. Speaking of which, you can dedicate up to 8GB of RAM to the iGPU thanks to an option hidden in the BIOS. The port selection remains great, and you also get a LAN, which is a rare find for a 14-incher. The upgradability is nothing to write home about. You can change the SSD and the WWAN card. The RAM and the Wi-FI 6E card are soldered.
Six display options are available. For starters, there are four 1200p IPS units, two of which are touchscreens. If this resolution is too low for your needs, you can get the 1400p model or the HDR-capable 2.8K 2880×1800 OLED.
The base layer of security extras seems fine. It features a privacy shutter, a dTPM 2.0 chip, a Lock slot, and a self-healing BIOS. If you can stretch your wallet even more, you can opt for a fingerprint reader, NFC, IR Web camera, and a Smart card reader.

Drivers
All drivers and utilities for this notebook can be found here: https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t14-gen-4-type-21k3-21k4/downloads
What’s in the box?
The box contains some manuals and a 45W or 65W Type-C charger. Depending on the retail configuration in your region, the package may include display adapters such as HDMI to VGA, USB-C to DisplayPort, or USB-C to LAN.
Design and construction
It’s perfectly normal that the ThinkPad T14 Gen 4 (AMD) and the Team Blue sibling look identical. The machines in Storm grey boast an all-aluminum build, while the Thunder black devices (like ours) have a carbon fiber lid and plastic body. The rigidity seems okay. The lid isn’t too flexible, and there are some slight bends here and there on the main body, but nothing too serious. The profile thickness is 17.9 mm. The weight varies depending on the chassis material and the battery model. The lightest possible configuration is in black and with a 39.3Wh battery. It stops the scales at 1.35 kilos. If you get a grey machine with a 52.5Wh, it’ll weigh 1.42 kg.
Unfortunately, you can’t open the lid with one, which isn’t exactly ideal for a business notebook.
The upper and the bottom bezel are thicker than the ones on the sides.
180-degree opening is possible.
All Web cameras sport a privacy shutter. The base unit has a 720p resolution. If you are making tons of video calls daily, the 1080p or the 5MP models offer better picture quality. Both come with facial recognition for Windows Hello.
The rounded Power button that doubles as a fingerprint reader is positioned next to the grill, which hides the two 2W Dolby Audio speakers. Users of the Storm Grey model will find a standard fingerprint reader, while it’s an optional extra for the Thunder Black model. The keyboard is pretty good for typing. It has decently sized Arrows and large keys with long travel. The backlight of the spill-resistant board is optional. The Trackpoint is placed in between the “G”, “H”, and “B” keycaps.
The Mylar surface of the touchpad is smooth. The unit itself is great for work since it’s accurate.
Large ventilation grills dominate the bottom panel, while hot air is expelled through a vent on the laptop’s right side.
Ports
On the left, you get a LAN, a 40 Gbps USB4 connector, a 10 Gbps USB Type-C 3.2 (Gen. 2) port, an HDMI 2.1 port (for up to 4K 60Hz external panels), a 5 Gbps USB Type-A 3.2 (Gen. 1) port that supports Always On functionality, and an Audio jack. On the right, we can spot a Kensington Nano security lock slot, one more USB Type-A 3.2 (Gen. 1) port, and an optional Smart Card reader. For models with optional 4G LTE, the SIM card tray is accessible on the rear side.
Both Type-Cs offer Power Delivery 3.0 and DisplayPort 1.4 capabilities.

Viewing Angles
Viewing angles are good. We take photos from different angles to evaluate the quality.
Also, a video with locked focus and exposure.
Color Coverage
The whole “sail-shaped” map below (Fig. 1) consists of all the colors we can see, while the black crooked line shows all the colors from real-world scenes and nature around us.
Then, we’ve drawn some of the most important and interesting color spaces, compared to the colors the panel of Lenovo ThinkPad T14 Gen 4 can show:
Standard/For Web: sRGB – widely used color space for most consumer devices, ideal for Web design and development
For Print: AdobeRGB – used in professional photo editing, graphic design, and print
For Photographers/Video Editors: DCI-P3 – used in high-end film production, post-production, and digital cinema
Premium HDR: Rec.2020 – the widest consumer ITU color standard, covering a massive 75.8% of the visible spectrum, a benchmark for premium HDR content
Lenovo ThinkPad T14 Gen 4: the yellow dashed triangle (– – – – – –) represents the range of colors this monitor can display.
In our tests, we calculated the total color coverage of the monitor at 49% of the sRGB color gamut and 39% of the DCI-P3 color gamut.
(Fig.1) Lenovo ThinkPad T14 Gen 4 covers 49% of the sRGB gamut
Brightness and Contrast
The maximum brightness in SDR mode is 317 cd/m² in the center of the screen and 300 cd/m² averaged across the surface with a maximum deviation of 9%.
The Correlated Color Temperature (CCT) on a white screen at maximum brightness is 6470K.
The contrast ratio is 1260:1.
Uniformity: Luminance, Contrast, and Color Deviation
The figure below shows the results from our uniformity test across different sections of the screen. It’s measured at 181 nits (Windows slider = 82%) — a brightness level we consider typical for standard working conditions.
DeltaE values below 4.0 are acceptable for regular users. For those working with colors, screens with DeltaE values no higher than 2.0 are recommended.
Color Accuracy
Let’s check the difference between real colors and those you’ll see on the Lenovo ThinkPad T14 Gen 4. We measure that distance in DeltaE – the higher the number, the more different they look.
Values below 4.0 are acceptable for regular users, while values below 2.0 are suitable for color-sensitive work. A value below 1.0 means the difference is indistinguishable to the naked eye.
For the next graph, we’ve selected 24 common colors, including dark/light skin, blue sky, green grass, etc.
Before our calibration of the Lenovo ThinkPad T14 Gen 4, the Average color accuracy was 6.0 dE (Fig. 2), and with our Design and Office profile, it lowered to 4.5 dE (Fig. 3).

Visibility in dark scenes
Have you ever watched a movie with dark scenes where you could barely see anything? This often happens because many display panels struggle to differentiate the darkest nuances, making them appear the same.
The next figure illustrates how well the display reproduces these dark nuances. The left side of the image shows the display with stock settings, and the right side shows it with our Gaming and movies profile activated.
On the horizontal axis are the grayscale levels, and on the vertical axis – the corresponding display brightness.
You can also check how your display handles the darkest nuances but keep in mind that this also depends on the settings of your current display and the surrounding light conditions.
Response time (Gaming capabilities)
We test the reaction time of the pixels with the usual “black-to-white” and “white-to-black” method from 10% to 90% and vice versa.
We recorded Fall Time + Rise Time = 17.6 ms. Short pixel response time is a prerequisite for a smooth picture in dynamic scenes.
After that, we test the reaction time of the pixels with the usual “Gray-to-Gray” method from 50% White to 80% White and vice versa between 10% and 90% of the amplitude.
Health Impact: PWM (Screen flickering)
Some use PWM to regulate their brightness, which means that instead of reducing the light intensity, they pulse or flicker. Our brain merges the image, so it appears darker, but this strains both it and our vision, especially when the frequency of the pulses is low. You can read more about that in our dedicated article on PWM.
In the graph below, you see the intensity of light at different brightness levels—on the vertical axis is the brightness of the emitted light, and on the horizontal axis—time.
The light from the backlight of the Lenovo ThinkPad T14 Gen 4 display is not pulse-width modulated, providing visual comfort in the discussed aspect.
Health Impact: Blue light emissions
Installing our Health-Guard profile not only eliminates harmful PWM when the laptop uses it to control brightness but also reduces harmful Blue Light emissions while keeping the colors of the screen perceptually accurate.
If you’re not familiar with the Blue light, the TL;DR version is – emissions that negatively affect your eyes, skin, and your whole body. You can find more information about that in our dedicated article on Blue Light.
Health Impact: Screen Reflectance
Glossy-coated displays can cause eye fatigue in high ambient light conditions due to reflections. We measure the level of screen reflection with the display turned off, at a 60° angle.
The reflectance of the Lenovo ThinkPad T14 Gen 4’s screen is 48.2 GU.
High Gloss: >70 GU
Medium Gloss: 30 – 70 GU
Low Gloss: <30 GU

Gaming and Movies
Have you ever watched a movie where, during dark scenes, you can barely see anything? Many displays fail to distinguish dark tones properly. Our Gaming and Movies profile enhances low-light performance, like HDR tech, using a gamma curve tailored to human perception — ideal for gamers seeking faster reactions and clearer visuals.
Health-Guard
Our Health-Guard profile protects your eyes by eliminating PWM flickering, reducing strain and fatigue, and minimizing harmful Blue light exposure that can disrupt sleep and health. It uses software dimming and a gamma curve tailored to human perception for comfort and safety during screen use.

Max CPU load
In this test we use 100% on the CPU cores, monitoring their frequencies and chip temperature. The first column shows a computer’s reaction to a short load (2-10 seconds), the second column simulates a serious task (between 15 and 30 seconds), and the third column is a good indicator of how good the laptop is for long loads such as video rendering.
Average core frequency (base frequency + X); CPU temp.
| AMD Ryzen 7 PRO 7840U (28W TDP) | 0:02 – 0:10 sec | 0:15 – 0:30 sec | 10:00 – 15:00 min |
|---|---|---|---|
| Lenovo ThinkPad T14 Gen 4 (AMD) | 2.88 GHz @ 49°C @ 32W | 2.90 GHz @ 58°C @ 32W | 2.49 GHz @ 68°C @ 27W |
| HP EliteBook 865 G10 | 3.76 GHz @ 46°C @ 30W | 3.39 GHz @ 56°C @ 25W | 3.32 GHz @ 72°C @ 25W |
| HP EliteBook 845 G10 | 3.76 GHz @ 46°C @ 29.2W | 3.41 GHz @ 54°C @ 25W | 3.18 GHz @ 72°C @ 25W |
The Ryzen 7 PRO 7840U inside the ThinkPad T14 Gen 4 can’t reach its 3.30 GHz base clock even in short stress. The machine doesn’t feel slow at all, but the frequencies aren’t optimal.
Comfort during full load
The fan sounds almost quiet in “Best Performance” mode when the CPU is loaded heavily. In this scenario, the keyboard doesn’t get toasty. Yep, the AMD version of the ThinkPad T14 Gen 4 is tuned for comfort, not for maximum performance.
You can tame the fan even more by choosing the “Balanced” mode, but it significantly reduces the clocks to around 1.40 GHz.
Battery
Now, we conduct the battery tests with the Windows Best Power Efficiency setting turned on, screen brightness adjusted to 180 nits and all other programs turned off except for the one we are testing the notebook with. The 52.5Wh battery lasts for around 12 hours of video playback. Оur test was conducted with the “Energy Saver” preset activated in the Windows “Power & Battery” menu.
Brightness: 180 nits; Display Mode: SDR
Time to Full Discharge: Higher is Better
Disassembly, Upgrade options, and Maintenance
To open this small 14-incher, you need to undo seven captive Phillips-head screws. You can also eject the SIM card tray on the back, but it’s not necessary.
Pry the bottom plate in the zones behind the hinges with a lever tool. Then, pop the back and the sides with a thin plastic tool. With that out of the way, raise the rear of the plate and lift it away from the chassis.
On the inside of the bottom plate, we can see that there is a dust filter in front of the bigger ventilation grill and cloth material for the smaller one.
Our device sports the optional 52.5Wh battery. The default variant for this Lenovo series is a 39.3Wh model. If you want remove it, you have to undo the six Phillips-head screws that secure unit to the base. Here, the connector is built into the battery. Wear gloves to avoid short electrical zaps. The capacity is enough for around 12 hours of video playback on a single charge.
The chips of the soldered memory are positioned underneath the cooling’s heat spreader, and there is a heat shield on top of them. You get up to 32GB LPDDR5x-6400MHz RAM in dual-channel mode.
The WWAN slot on the right is for optional 4G LTE connectivity. Next to it is the M.2 slot compatible with 2280 Gen 4 NVMe drives. We found a long thermal pad below the SSD.
The Wi-Fi 6E card is placed in the upper part of the motherboard.
The cooling comprises a large fan, two heat pipes, a side-mounted heat sink, and a heat spreader.
Verdict
The AMD-based ThinkPad T14 Gen 4 prioritizes user comfort, with a focus on quieter operation, rather than pushing for peak performance. The Ryzen 7 PRO 7840U can’t reach its base clock even in short stress. On the flip side, the fan is almost quiet, and the keyboard doesn’t become scorching hot during 3D rendering. Despite the not-so-good processor clocks, this notebook doesn’t feel slow at all for normal work. Speaking of which, the input devices are very good. The only complaint here is that you have to pay more for a keyboard backlight.
The 1200p IPS screen (NV140WUM-N43 (LEN403D)) is okay for standard, unpretentious usage. It’s a PWM-free display with wide viewing angles and 317 nits of maximum brightness. The color coverage and the accuracy are not impressive. If that’s important for you, the optional 1400p IPS or the 2.8K OLED are the way to go if you don’t mind paying more for one of these screens.
The AMD-powered ThinkPad T14 Gen 4 is a light 14-inch office device with good comfort, long battery life, and rich port selection.
