Well yes, in the end it was also my turn to get my hands on a notebook equipped with the new AMD Ryzen 4000 processors in their ULV version. After the Asus ROG Zephyrus G14 with Ryzen 4000H, it is therefore time to try the low-consumption version of the new AMD platforms (announced in January), which promise excellent performance and autonomy in line with the best competing solutions on the market.
In fact, the new Yoga Slim 7 has arrived from Lenovo, which we can consider as the successor of the Yoga S740 and which is equipped with the Ryzen 7 4700U. Ok, I admit it, I was looking forward to trying a laptop with this platform and I can already tell you that my expectations have not been disappointed. To find out how this notebook really does, you have to keep reading below!

SOFTWARE AND AUTONOMY
No, I don't start by telling you about the new Ryzen, I want to keep you a little on the thorns. I begin by telling you instead that once you have extracted the Slim 7 from the box you will be faced with a solution made with care, sober and very solid. The chassis is 15 mm thick and is made entirely of aluminum, a detail that allows the notebook to maintain good rigidity without sacrificing acceptable weight. There is talk of about 1.4 kg: they are not very few, but still remain within a range that allows you to transport the laptop in a sufficiently comfortable way.
The design is very sober and incorporates the lines and style of the latest generations of Lenovo notebooks. I really liked some details like the contrasting Lenovo logo in the corner of the panel behind the display and the engraving Yoga 7 Series on the frame. They are small details, it is true, but it is also in these things that the solutions of a certain range differ.
We said of the solid and rigid body in all its points, including the palm rest and the piano of the keyboard. A keyboard that therefore does not flex and is characterized by good-sized keys, with the classic U-shape typical of Lenovo solutions. As always we are faced with one of the best solutions around, even if this time I found a small flaw. The race is good and the click is heard without being too loud and annoying but the keys are not exactly as stable as I would like. There is a small, or rather very small, side game that will probably be imperceptible to most, but which, if you are used to certain standards, you cannot help but notice.
At the center of the palm rest, aligned with the space bar, we find the touchpad. It is not huge but not even small, let's say that maybe it could have gnawed a few more millimeters but even so it remains very usable. The fingers slide well and the answer is always precise. Multiple touch and system gestures are obviously supported.
On the sides of the keyboard we find the grids behind which the speakers are hidden which are equipped with a fairly high volume and an average quality of the solutions of this kind. Obviously there are not many lows but we know that there are few solutions that manage to do better and in general the highs are often predominant even in the mids.
In the upper part of the display, in the center, the frame creates a sort of notch inside which we find the 720p webcam and infrared sensors for face recognition that enable quick access to the system via Windows Hello. There is no sensor for fingerprint recognition but given the presence of the facial one I cannot consider it a serious deficiency.
I close with two words about the expansion ports, whose number and variety are an added value for this Yoga Slim 7. On the right side we have two USB 3.1 Type A and a microSD card reader, while the left one houses two Type C , including one with video output, one HDMI and the combo audio jack for headphones and microphone. What to say? finding all these doors on such a subtle solution is increasingly a rarity.
Lenovo Yoga Slim 7 offers a 14-inch display with fullHD resolution and classic 16: 9 format. It is an IPS type panel with a glossy finish and an anti-glare treatment that I wouldn't exactly call exceptional. Honestly on a solution of this type, without touch display and without pen support, I do not agree with the choice of using a glossy display. Unless strictly necessary, I always tend to prefer opaque panels, which are able to guarantee better visibility especially in the presence of direct light sources.
Removed this consideration, we are talking about a discreet screen anyway. The maximum brightness stops at around 300 cd / m2, enough to easily use it indoors even in very bright environments. Outdoors, however, better if you limit yourself to the areas of penumbra.
Measurement using the colorimeter and Calman software shows good coverage of the sRGB standard, we are practically 100%, and the average delta E not exceptional but still acceptable. Let's talk about 5.8 for grayscale and just over 3 for colors. We are not within what is considered as the tolerable error threshold, but we still remain at a level where the differences with the standard are still acceptable.
And here we are at the highlight of the whole review, or the one in which I talk a little about this new AMD platform and what accompanies it inside this Lenovo Yoga Slim 7. As I already told you, the configuration in my hands is equipped with a Ryzen 7 4700U accompanied by 16 GB of LPDDR4X RAM at 3200 MHz, still not widespread if we look at the data sheets of most notebooks on the market. The CPU is octa-core, with a base frequency of 2 GHz made with a 7nm production process. The GPU is an AMD Radeon RX Vega 7, natural evolution of the Vega that we found integrated in the previous generation solutions.
TECHNICAL SHEET LENOVO YOGA SLIM 7 (AMD):
- Display: 35.56 cm (14 ") Full HD (1920 x 1080) IPS, 300 nits
- CPU: AMD Ryzen 7 4700U / octa-core 2.0 GHz base clock
- GPU: AMD Radeon RX Vega
- RAM: 16 GB LPDDR4X at 3200 MHz
- Storage: 1 TB NVMe PCIe SSD
- Connectivity: Wi-Fi 6 (Wi-Fi 2 x 2 A), Bluetooth 5.0
- Ports: 2 USB Type A 3.1 Gen 2, USB C 3.1 (DP + power), USB C 3.1, Micro SD, HDMI, Audio Jack combo
- Battery: 60.7 Wh
- Dimensions: 32.06 x 20.8 x 1.49 cm
- Weight: 1.4 kg
The only upgradeable component of all the equipment is the SSD, obviously NVMe PCIe, which still offers 1 TB of space and sequential read and write speeds in excess of 3000 MB / s. On the motherboard there is a second M.2 slot which, reading online, seems not to be used simultaneously with the one in which we find the SSD installed. In a nutshell there is but I don't think it will be very useful.
Obviously, as for all our tests, we have put under pressure the new Ryzen 7 4700U loading 100% of all cores for over 10 min and the result is what you see in the graph above. Core frequencies stabilize at around 3.2 GHz and remain there for the duration of the test. The TDP is stable around 30W, while the average temperature is 96 degrees. You may have guessed it too, it is a nice push implementation but I must say that, despite the internal temperatures, the keyboard and the body remain always quite cool; in fact, it never goes above 37 degrees. All this obviously happens after setting the High Performance mode within the Lenovo Vantage app. If you use more conservative profiles, the frequencies will be a little lower and the system will tend to keep the components fresher at the expense of a few MHz.
At this point I could not add a little load on the GPU and therefore with both components at 100% committed I repeated the test and verified that the frequencies drop down to 2.5 Ghz but at the same time also the temperatures, both at inside and outside significantly fall. In detail we talk about 75 degrees on the CPU and 32-33 degrees outside. The GPU frequency is instead stable around 700 Mhz.
I would say there is no doubt therefore, this is a notebook with which you can carry out all standard business operations with your eyes closed. But not only that, the power available and the way in which the platform was developed also allow you to run much more demanding programs than the classic Office suite without too many limitations. For example, I have used Photoshop and Lightroom several times in complete tranquility and I have also tried successfully to edit a 4K video with Premiere Pro. Obviously I am talking about basic editing, no special effects or too complex transitions. The timeline is handled correctly and the preview is quite responsive.
Can we play with it? No, it's not a gaming notebook. Despite the excellent CPU, in fact, the Radeon RX Vega that we find here is not a GPU designed to run the most recent AAA titles. If anything, this is good CPU support for all those applications that support graphics acceleration, for example. This does not mean that graphically undemanding titles such as the various Fortnite and Overwatch run with a moderate fluidity in fullHD even with medium detail.
Before talking to you about autonomy, which is another aspect that surprised me, I would like to say a few words about software. I'm obviously not talking about the operating system, which we probably all know quite well, but about the Lenovo Vantage application. It is a sort of control center within which we find all the information regarding the notebook, from the data sheet to the warranty and assistance, but also a series of tools that we can activate or deactivate to take full advantage of the possibilities of this car.
I have already mentioned how to use it: you can switch from "High Performance" to "Energy Saving" or "Intelligent Cooling", each with its own characteristics and usage scenarios, or we can activate rapid charging, which in 30 minutes recharge 50% of the battery, or select the conservation mode. In this case the battery will never be charged more than 55-60%, in order to limit its deterioration as much as possible over time. In short, one of those software that you may curse initially because you would like a clean system but then you realize it is very useful.
And here we are talking about autonomy. The battery inside this Lenovo Yoga Slim 7 is 60.7 Wh and allows you to get really interesting results. Working under WiFi with the Improved Battery setting, it is possible to cover over 10 hours of continuous use. Then lowering the brightness of the screen to around 50% you can exceed 11 hours without too many problems. Under full load, however, the battery discharges completely in about 2 hours.
|I work daily Internet over Wi-Fi||-9.2%||10.8 hours|
|Netflix HD on the Metro app||-9.6%||10.4 hours|
|Rendering Premiere Pro / Games||-52.5%||1.9 hours|
|Draining in standby (Connected Standby On)||-0.1%||41 days|
50% screen brightness, 50% audio. Energy mode "Battery Enhanced".
Slim 7 is charged via USB C and with the charger in a 65W pack it takes about an hour and a half to fully charge it. As already mentioned, there is also the quick charge that allows you to get up to 50% charge in just 30 minutes.
We are therefore at the moment to draw conclusions and as always the first thing to do is to talk about price. Yoga Slim 7 in the configuration we tested with Ryzen 7 4700U, 16 GB of RAM and 1 TB SSD costs 1299 euros. Much? Well, in absolute value yes, they are not figures that everyone can afford to spend; but you can take on an expense of this type, then be sure that the solution that you bring home is absolutely valid.
Alternatives? I would say Dell XPS 13, which however starts from a slightly higher price, or Huawei MateBook 14, positioned at exactly the same figure but with Intel platforms of the tenth generation. In short, it is not cheap but it is not overpriced and if the street price should drop to around 1000 euros it would probably become one of the most interesting notebooks in the high end of the market.
