Lenovo Yoga Slim 6 14 laptop review: Premiere for the Radeon 740M
An all-rounder with an OLED display.
While OLED panels are now widespread, the Ryzen 5 7540U is quite a rare specimen. In our review, the iGPU Radeon 740M comes face-to-face with the faster AMD models and competition from Intel.Florian Glaser, 👁 Florian Glaser (translated by Andrew Dickson) Published 🇩🇪 🇫🇷 ...
Verdict
If you don't have any special demands regarding GPU performance, the Lenovo Yoga Slim 6 14APU8 is an almost comprehensive all-around laptop that doesn't make any major missteps. The relatively economical Ryzen processor is housed in a stylish and premium-looking case equipped with good input devices and (still) a sufficient number of ports. If your primary use case for the device is indoors, the high-contrast OLED screen does an impressive job, although, at slightly less than 400 cd/m², the brightness could be a touch higher due to its highly reflective surface.
The emissions and battery life generally give no cause for complaint. The Yoga Slim 6 runs both cool and quietly. However, purely from a value-for-money perspective, the 14-inch device has its work cut out against some of its competitors. As expected, the Radeon 740M built into the Ryzen 5 7540U is often significantly behind the Radeon 760M or 780M and both the Intel Arc 7 and Arc 8, found in similarly expensive machines. For this reason, casual gamers, in particular, would be better served by the company's own IdeaPad Pro 5 14AHP9.

Specifications
Case
The Slim 6 looks similar to other devices in the Yoga series. Lenovo uses an eye-catching design that cuts a good figure in every environment and on any occasion. Thanks to the use of metal, the chassis feels very premium and offers good stability (only the middle area of the base unit gives slightly when pressed). There can be no complaints concerning the build quality.
An additional highlight is the generous opening angle of 180°. The hinges are set quite firmly but still allow for one-handed opening. The low weight of just over 1.3 kg also ensures good transportability. On top of this, the device is a mere 1.5 cm thick, and this lends it a very slim appearance.
Features
Interfaces
Lenovo has equipped the 14-inch laptop with two USB-C ports (including DisplayPort and PowerDelivery, one of which is USB 4) and a USB-A port. These are joined by an HDMI 2.1 output and a combined audio jack. Buyers will have to do without an Ethernet port and a card reader. However, using a mouse is a piece of cake since all of the ports can be found on the rear of the case.
Communication
The Slim 6's wireless communication is taken care of by Realtek's chip (RTL8852CE). It is responsible for solid to good, but not exceptional, results (our measurements were carried out at a distance of 1 m from our reference router).
Webcam
The Full HD webcam tends to deliver standard fare whereby the color accuracy and image sharpness are a bit better than some of the competing devices that are often only equipped with 720p webcams. Top: Lenovo has fitted a physical shutter.
Accessories
The laptop comes with a few information booklets and a pleasingly compact and light 65-watt PSU.
Maintenance
The bottom of the case is held in place by six Torx screws and some very tight clamps, which make opening the chassis a real challenge. Inside the device, you are greeted by two fans, each of which has a heat pipe connected to the CPU. The RAM is onboard, meaning it can be neither swapped nor upgraded. The SSD can be swapped for a larger model (maximum type 2280). A second M.2 slot would have been more practical here.
Sustainability
Sustainability can be classed as mid-range. Although Lenovo uses plastic film and two foam inserts for its laptop packaging, they are at least labelled accordingly. According to the manufacturer's website, the laptop and the PSU are, to a certain extent, made from recycled materials.
Warranty
The warranty period is 24 months.
Input devices
Keyboard
As you would expect from Lenovo devices, the keyboard has a good pedigree. The curved keys are mostly arranged sensibly and provide quite a good typing experience. Of course, there is also multi-level adjustable lighting, and, in this case, it's white.
Touchpad
The touchpad is roughly 12 x 7.5 cm in size and can also hold its own with the competition. For our tastes, it sounds a bit flimsy, however, despite this, inputs are registered reliably. Additionally, the touchpad has a nice surface and gesture support. Overall, the input devices are impressive.
Display
The OLED display has the usual strengths and weaknesses you would associate with that technology.

* ... smaller is better
While the contrast ratio, black level and response time are all entirely convincing, buyers still have to live with occasional flickering (480 Hz) as well as a reflective display surface. The brightness could also be a bit higher for outdoor use: Just under 400 cd/m² is only mediocre for glaring light.
When it comes to color accuracy, there is pretty much nothing to complain about. This is an area in which the Yoga Slim 6 scores quite highly.
The same applies to color space: 100 % sRGB and DCI-P3 achieve a respectable 97 % AdobeRGB. Typical for OLED displays, the viewing angle is also on a good level.

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 480 Hz |  | |
| ≤ 86 cd/m² brightness | |||
The display backlight flickers at 480 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 86 cd/m² and below. There should be no flickering or PWM above this brightness setting. The frequency of 480 Hz is relatively high, so most users sensitive to PWM should not notice any flickering. However, there are reports that some users are still sensitive to PWM at 500 Hz and above, so be aware. Flickering occurs at relatively low brightness settings, so extended use at this brightness setting or lower can cause eyestrain. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8320 (minimum: 5 - maximum: 343500) Hz was measured. | |||
Performance
While the Yoga Slim 6's CPU performance can be best described as mid-range, the GPU performance is only in the entry-level segment. 16 GB of RAM and a 1 TB SSD are typical for this price category.
Test conditions
The preinstalled Lenovo Vantage software includes three different energy modes which affect both the fan noise as well as the speed. Our measurements are based on the default "adaptive" mode which maintains a reasonable balance between performance and noise.
| Cyberpunk 2077 (FHD/Ultra) | Battery Saving Mode | Adaptive (Auto) | Performance |
| Noise | 32 dB(A) | 37 dB(A) | 42 dB(A) |
| Performance | 8fps | 10fps | 1fps |

Processor
The Ryzen 5 7540U is a Phoenix generation (4 nm) six-core processor that has a 16 MB L3 cache and can process up to 12 threads simultaneously via SMT. AMD specifies clock speeds of between 3.2 and 4.9 GHz under load. In the benchmark test course, the Yoga Slim 6 didn't manage to hit the heights but still delivered solid results for everyday tasks. Our CPU rating sees the 7540U between the Core Ultra 5 125U and the Core Ultra 5 125H, with the tendency tilted toward the latter. However, the Slim 6's performance is not entirely as stable as our Cinebench loop suggests. In extreme cases, the results fluctuate by around almost 200 points.

System performance
The system performance ranking is roughly based on the CPU ranking, and over 6,000 points in PCMark 10 is by no means a bad result. Subjectively, the computer also runs pleasantly fast, whether it's the boot time, loading times or data transfers.

DPC latencies
By contrast, the latencies are rather less than perfect. The LatencyMon tool suggests there are possible problems with audio and video editing in real-time, which might, however, only affect users with special requirements.

Mass storage
When it comes to mass storage, Lenovo has packed a 1 TB Micron NVMe drive into the case, and it is neither particularly slow nor fast. Unlike the CPU, the SSD's performance is very stable. The DiskSpd loop ran without any drops in performance, which was not the case with the Slim 5.

Graphics card
Compared to the extremely popular and successful iGPU Radeon 780M, the Radeon 740M has to make do with 256 rather than 768 shader units, in other words, a third thereof. Fortunately, the speed doesn't drop identically, although, despite this, there are considerable differences and gaps. If you take both of the 3DMark synthetic measurements, the Radeon 740M works, on average, almost 40 % slower than the Radeon 780M and Intel Arc 7, positioning itself around 20 % behind the Radeon 760M (512 shaders). However, the Intel Graphics 4 core gets beaten by a few percent.

Gaming performance
While the 780M is entirely sufficient for casual gamers and can at least run most titles relatively smoothly at Full HD and low settings, the Radeon 740M tends to only cope with undemanding or old games such as Dota 2 and Counter Strike 2. For other titles that do not run smoothly according to our tests, FSR can provide assistance. The gap to the faster iGPUs is somewhat smaller than in the synthetic benchmarks, but it's still noticeable.

Emissions
Noise emissions
In adaptive auto mode, the Yoga Slim 6 doesn't get too loud. Around 37 dB(A) under load is clearly audible, but this should be acceptable to most users, especially considering most of the competing devices are louder in this area. In idle operation and when performing basic office, video and internet tasks, the fans are either completely off or run at a (still) pleasantly acceptable volume of 27 to 29 dB(A).

Temperature
While the top of the chassis doesn't get warmer than 40 °C under full load, we recorded slightly higher temperatures on the base. However, they are still on a reasonable level. In idle situations, the whole chassis remained below the pleasantly cool 30 °C mark.
(+) The maximum temperature on the upper side is 39 °C / 102 F, compared to the average of 35.9 °C / 97 F, ranging from 21.4 to 59 °C for the class Subnotebook.
(-) The bottom heats up to a maximum of 46 °C / 115 F, compared to the average of 39.3 °C / 103 F
(+) In idle usage, the average temperature for the upper side is 26.9 °C / 80 F, compared to the device average of 30.8 °C / 87 F.
(±) 3: The average temperature for the upper side is 34 °C / 93 F, compared to the average of 30.8 °C / 87 F for the class Subnotebook.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 29 °C / 84.2 F and are therefore cool to the touch.
(±) The average temperature of the palmrest area of similar devices was 28.2 °C / 82.8 F (-0.8 °C / -1.4 F).

Stress test
In the stress test with the Furmark and Prime95 tools, the CPU throttled to around 2.1 GHz, but, in return, it only heated up to between 50 and 60 °C. In the Cyberpunk test, the clock speed and temperature values were similar.
Speakers
The sound created by the 2.0 system is in the middle of the pack. While the highs and mids are quite good, the bass still has quite a bit of room for improvement. The maximum volume is a decent 81 dB(A).

Power consumption
In idle mode, the power consumption is good, measuring between 5 and 10 watts (averaging 6 watts). Under load, our measuring devices recorded values of between 41 and 58 watts, and this is justified given the performance on offer. The included 65-watt PSU is sufficiently sized.

Battery life
The battery runtimes are also impressive without being among the top performers. Just under 10 hours of Wi-Fi surfing at 150 cd/m² reduced brightness ought to be satisfactory for most users. The HP ZBook Firefly 14 G10 has proven itself to have a particularly long battery life despite its smaller battery (51 vs 60 Wh).
