Lenovo Yoga Slim 7 14ARE05 in Review: Compact Powerhouse with Good Battery Life
Lenovo’s Yoga Slim 7 14ARE05 is a good-looking compact 14-inch notebook. Aside from its internal hardware it is identical to the Yoga Slim 7 14ARE05 (Ryzen 7 4800U) and Yoga Slim 7 14IIL05 (Core i7-1065G7, GeForce MX350). Its competitors are devices such as the Asus Zenbook 14 UX425EA or Acer Swift 3 SF314-42.
We are not going to cover case, connectivity, input devices, speakers, and display as part of this review. If you want to find out more about these aspects, you will find detailed information in our Yoga Slim 7 14ARE05 (Ryzen 7 4800U) review.

Display – IPS Included
Both contrast ratio (2067:1) and overall brightness (365.6 nits) of the reflective 14-inch FHD IPS display with great viewing angles are decent. We were also unable to detect any signs of PWM flickering, which is even more good news.
The panel is identical to its sibling’s. Nevertheless, our test results differ slightly. This difference is to be expected given that two even seemingly identical panels will never be truly identical.

Performance – Ryzen APU able to Perform Freely
Lenovo’s Yoga Slim 7 14ARE05 is a 14-inch notebook with more than enough performance for office and internet applications. Our particular review unit started at around 950 Euros. Other SKUs are available as well.
Test Conditions
Lenovo’s preloaded Vantage software allows users to pick between one of three available performance modes: Intelligent Cooling, High Performance, or Battery Saver. For the purpose of our benchmarks, we chose for the “Intelligent Cooling” mode given this is what is enabled by default. In addition, we ran a few benchmarks in the other two modes as well. You will find those results in the tables below.
Processor
The Yoga Slim is powered by a Ryzen 7 4700U (Renoir) APU by AMD. Its CPU consists of eight cores running at a base clock speed of 2 GHz with a turbo boost speed of up to 4.2 GHz. Simultaneous Multithreading (two threads per core) is not supported.
The CPU ran at up to 4-4.1 GHz for a short period of time while performing our CineBench multi-thread test. Afterwards, it dropped to 3.7-3.8 GHz. On battery, the device starts out at 1.3-2.5 GHz and slowly speeds up to 3-3.7 GHz. Single-thread tests were completed with clock frequencies fluctuating between 1.4 and 4.2 GHz.
We run the CineBench R15 multi-thread test for at least 30 minutes in a loop in order to determine whether or not a processor is capable of utilizing high turbo-boost clock speeds under sustained load. The scores dropped slightly between the first and fifth run and settled at a relatively consistent level afterwards. Turbo boost is applied, but only for a short time at high speeds. This changes when enabling the “High Performance” mode, which resulted in consistently higher clock speeds throughout the entire test.

All things graphics are handled by AMD’s integrated Vega 7 GPU, which supports DirectX 12 and runs at clock speeds of up to 1,600 MHz. Its 3DMark results were at a level expected of this GPU, and graphics performance did not increase after we enabled “High Performance” mode.

Gaming Performance
The Yoga Slim 7’s built-in APU is capable of running many games smoothly. Most games will run smoothly in HD resolution (1280 x 720) with medium to sometimes even high details. Games with more moderate requirements will allow for even higher settings. Many current games are playable as well, albeit those will require lower settings in order to run adequately smooth.

We run Witcher 3 for 60 minutes in FHD with maximum details in order to determine whether or not a device is capable of maintaining high frame rates over long periods of time. The avatar remains stationary throughout the entire test. In this case, we found no drop in frame rates, and the GPU ran at full speed throughout the entire test.

Emissions & Energy – Lenovo Computer with Decent Battery Life
Noise Emissions
Lenovo’s 14-inch notebook remained fairly quiet regardless of load. When idle, both fans are completely off quite often, and the device is completely silent. The notebook has to be subjected to high load for quite a long time in order to spin up the fans, for example by running our Witcher 3 test. We were able to determine a peak of 38 dB(A) and a somewhat lower 32.3 dB(A) while running our stress test.

Temperature
When running our stress test (Prime95 and FurMark simultaneously for at least one full hour) CPU and GPU run at 3.7-3.8 GHz and 1,200-1,300 GHz for a few seconds, respectively. Afterwards, clock speeds drop slowly and gradually to 2.1-2.2 GHz and 600 MHz. On battery, they dropped even further to just 1.8 GHz (CPU) and 400 MHz (GPU). Keep in mind that our stress test is an extreme load scenario that does not occur during everyday use. We use this test to determine potential throttling and stability issues.
Lenovo’s laptop remained fairly quiet overall. When running our stress test, we found only a single hot spot of more than 40 °C. Temperatures were much lower during everyday use.
(+) The maximum temperature on the upper side is 38 °C / 100 F, compared to the average of 36.9 °C / 98 F, ranging from 21.1 to 71 °C for the class Multimedia.
(±) The bottom heats up to a maximum of 42.4 °C / 108 F, compared to the average of 39.1 °C / 102 F
(+) In idle usage, the average temperature for the upper side is 24.6 °C / 76 F, compared to the device average of 31.2 °C / 88 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 28.3 °C / 82.9 F and are therefore cool to the touch.
(±) The average temperature of the palmrest area of similar devices was 28.8 °C / 83.8 F (+0.5 °C / 0.9 F).

Power Consumption
We found no power consumption irregularities. Power consumption when idle peaked at 9.6 W and increased to 58.4 W when running our stress test (Prime95 and FurMark simultaneously for at least one hour). The power supply is rated at 65 W.
Off / Standby | 0.6 / 0.7 Watt |

Battery Life
In our real-life Wi-Fi test simulating a typical power consumption while browsing the web via a script with power saving options disabled and brightness normalized to 150 nits the Slim 7 lasted for 10:52 hours.

Cons
Verdict
The combination of Ryzen 7 4700U APU, 16 GB of RAM (dual-channel mode, soldered, no unpopulated slots), and 1 TB NVMe SSD performed very well when we put the laptop through its paces. A secondary NVMe SSD slot is available should you require more storage space.
Lenovo’s Yoga Slim 7 14ARE05 is a compact, powerful, and portable 14-inch all-rounder. We would have preferred a matte display, though.
The notebook remained fairly cool and quiet overall. The backlit keyboard proved itself suitable for everyday use. Its FHD IPS display offered wide viewing angles, adequate color accuracy, acceptable color space coverage, decent brightness, and a great contrast ratio. Unfortunately, Lenovo opted for a reflective display.
Thanks to its 61 Wh battery, the device lasted for almost 11 hours in our Wi-Fi test. A benefit is its USB-C power supply, which can be plugged into both USB-C ports (1x USB 3.2 Gen 1, 1x USB 3.2 Gen 2). DisplayPort over USB-C is only available by the USB 3.2 Gen 2 port while Power Delivery 3.0 is supported by both. Unfortunately, Thunderbolt 3 is only available on the Intel-equipped SKUs. We would love to see a potential successor alleviate this flaw.
