The CES in Las Vegas represents the beginning of the year appointment chosen by important companies in the high tech market to introduce products that will find diffusion in the following months. The 2020 edition was supposed to represent for Intel the right opportunity to relaunch the category of portable with flexible screen, which companies like Lenovo have started to explore – see the ThinkPad X1 (opening photo) presented in November.

Opportunity missed, given that a recent report provided by Digitimes stresses how the house of Santa Clara has decided to to put off there presentation of the CES 2020 of a laptop equipped with a 17 "flexible screen. No details are known about the product – probably a reference design for similar models – but they would be two causes that determined the decision to postpone the launch: on the one hand Windowson the other supply chain.

Windows 10X, the version of Microsoft's operating system for dual-screen laptops, has not yet reached a level of development such as to consider it suitable to show the potential of the new category of devices – without too many turns of words the source defines it as the software yet immature. It is recalled that the Redmond house presented Windows 10X last October and that it will also be on board the Surface Neo, expected by the end of 2020.

The other reason is attributable to flexible screen supplies that I am still insufficient – therefore the other manufacturers could hardly give life to laptops based on Intel's reference design in a short time. It is legitimate to hypothesize that the production difficulties of flexible screens of such large dimensions (17 ") may be even greater than those encountered with smaller diagonal panels.

The result is that Intel could be forced to wait (at least) for mid 2020 to relaunch the project. It is not the first time that the US company has pushed the accelerator on dual-screen laptops: in 2018 it introduced Tiger Rapids, a laptop with two separate screens. However, the decision to resort to an emerging technology such as that of flexible screens has increased the degree of difficulty.

Among all notebook manufacturers Lenovo is among those who believed and continues to believe most in convertibles and 2in1, its Yoga I am a certainty and I am probably the most complete series present on the market. A line of devices that includes products for all price ranges and that satisfies all types of users.

We started from the top to try the latest update of the range with the review of the Yoga C940, terminal that has satisfied us in many respects. Today we continue the analysis of the line up, however, going down a step, the protagonist is him Yoga C740 which offers a much lower starting price, under 1000 euros. still managing to maintain many of the good impressions given by the superior model.

Lenovo Yoga C940 review with Ice Lake CPU at 10nm

Nov. 21


First I would like to focus on what we find inside this Lenovo Yoga C740 and how it behaves in terms of hardware. Like all the latest generation Lenovo Yoga products, the one seen for the first time in Europe during the last IFA in Berlin, the C740 also arrives with the new 10th generation Intel Core processors. In the case of the model at our disposal we have in particular a Core i5-10210U accompanied by 8 GB of LPDDR4 RAM and a 512GB PCIe SSD Samsung branded, the consideration for the OEM market of the latest 970 EVO Plus. An NVMe SSD capable of about 3500 Mb / s read and 3000 Mb / s read.

The latter, together with the card WiFi AX Intel Wireless 22560 is the only replaceable and upgradeable component but, given the excellent performance of both, you will hardly feel the need to perform these operations. By opening the rear panel we note that the RAM is soldered and there are no slots for expansion. In addition to this we cannot fail to observe how small the motherboard is with all its components on board and how much empty space there is around the small cooling fan. In this regard, Lenovo perhaps could have risk something more and insert a larger fan, with a consequent higher cooling capacity and, therefore, greater efficiency and better performance.

Technical specifications Lenovo Yoga C740

  • CPU: Intel Core i5 10210U / 4 cores at 1.6 – 4.2 GHz
  • GPU: Intel UHD Graphics
  • Screen: 14 inches 16: 9, 1920 x 1080 pixels 157 PPI, touch with pen support, IPS LCD
  • Storage: Samsung SSD PM981 MZVLB512HBJQ, 512 GB
  • Ports: 1 USB 3.1 Gen 1 Type-A, 2 USB 3.1 Gen 1 Type-C, Audio Connections: Kombo-Audio, 1 Fingerprint Reader
  • Network: Wi-Fi ax Intel AX22560 / Bluetooth 5.0
  • Dimensions: 321.8 x 214.6 x 14.9 mm / Weight: 1.37 kg
  • Battery: 51 Wh / Power supply: 65 watts / OS: Windows 10 Home
  • Other: Webcam: 720p / Speakers 2x 2 W / Keyboard illuminated with white LEDs

Mind you, not that the performance of this Yoga C740 is so negative, far from it, all the most common operations can be completed without problems and for 90% of users this hardware is a sufficient platform to work without problems of any kind. The most classic programs are well supported and run properly, from the full Office suite to multitasking browsing on Chrome with over 10 open tabs. But not only that, we can also venture a little bit of basic photo editing with Photoshop or export and catalog our photos with Lightroom without incurring particular slowdowns. Video editing with Premiere Pro? Better if you limit yourself to 1080p and prepare to make it not exactly lightning fast.

Unfortunately we don't have discrete graphics cards and not even the latest Intel Iris Plus that guarantee performance comparable to the NVIDIA MX series. This detail excludes the possibility of playing the latest titles even if, for a few minutes of leisure, you can run the porting of the smartphone games that you find on the Microsoft Store without problems.

Here too, as on the Yoga C940, we have the app Lenovo Vantage which allows us to modify the parameters related to cooling and to activate or deactivate the "Performance" mode. What changes? Basically it is an option that acts on PL1 and PL2, or the consumption limits in Watts that can be reached by the CPU. In the case of silent mode these values ​​are 20 and 25 Watts, but they rise to 29 and 51 Watts in Performance mode with the possibility of therefore having a higher peak and a longer stay at frequencies higher than the basic one.

The test charts show a all in all fairly standard trend. Let's also say that Lenovo has been conservative and has preferred to maintain a profile that allows the machine to always run at very comfortable temperatures, favoring the stability of the system over performance. Considering the target I think it is an intelligent and shareable choice. As evidence of this, even during the stress test, with the processor and GPU fully loaded, the machine is called to lower core frequencies down to 1.0 GHz keeping though always very low temperatures between 60 and 70 degrees. There are therefore no episodes of thermal throttling and the system is always responsive even when it is engaged to the maximum of its possibilities.

Finally, also outside, we always have a very low operating temperature. On the keyboard it never exceeds 40 degrees and in the back we have a very similar scenario, which allows us to work by holding the laptop on the knees without them cooking.


We are faced with a product that incorporates the latest Yoga solutions in style, the shell is made entirely of very resistant and optimally assembled metal materials, a combination that gives great rigidity to the whole solution. The panel behind the display does not deform and the keyboard surface, as well as the palm rest, is very resistant and does not flex.

The hinge is divided here into two blocks, unlike the C940 which has a single large central hinge with integrated soundbar, but still allows the display to rotate 360 ​​degrees, as a prerogative of Yoga solutions. These hinges appear very solid and, perhaps, even a bit too harsh when stressed. In fact, you cannot open the notebook with one hand, because of the too much resistance offered by the same and the complete lack of a grip on the front that allows a firmer grip.

The keyboard, as per Lenovo tradition, it is very, very well done: the keys are stable, backlit, have the classic shape of the keycaps of the Chinese company's keyboards and a good run, which allows us to type comfortably and get to know the layout very soon. I mean, what do I tell you to do? Also this time with the Lenovo keyboard has hit the center.

The touchpad is not huge, on the contrary, but it would have been difficult to insert a larger one due to the limited space available. It remains wide enough to allow us to take advantage of the Windows gestures, supported thanks to the integration of the Precision drivers.

On the sides of the keyboard there are two perforated slits behind which they are hidden stereo speakers which offer sound with good overall quality and a sufficiently high volume. Let's also say that, MacBook Pro 13 excluded, they are probably among the best speaker sets that we have tried on devices of this size. This is also thanks to the tuning carried out in collaboration with Dolby which also holds the certification Atmos.

And I close this parenthesis on aesthetics by talking about the connection ports that are undoubtedly few. On the left side we have the headphone jack and two USB Type C 3.1, both enabled for charging but neither with Thunderbolt support. The opposite side hosts instead a USB Type A, always 3.1, and the on / off button. I would certainly have liked a memory card reader, even a microSD, and maybe a second standard USB since, if we want to carry the pen supplied with the notebook, the present one will always be occupied by the accessory used for this task.


I have certainly not forgotten the display, undoubtedly one of the most convincing elements of this 2in1. It is a 14-inch diagonal panel, IPS LCD Touchscreen with FullHD resolution. So far nothing in particular but already from the first ignition we still note the good quality of the same which shows bright colors and a decent anti-glare finish despite the touch.

To the colorimeter test our good impressions are confirmed after all. We have a maximum brightness on 100% of the panel equal to about 250 cd / m2 which go up to something more than 300 including smaller portions of the screen. The contrast is sufficient and the display remains visible without too many problems in most situations.

However, the accuracy in the reproduction of colors is most impressive. THE Delta E mids are indeed very low both for the grayscale and for the colors. In detail, we are talking about a value of 2.8 for grays and 1.8 for colors, both below tolerance and with a maximum error of 3.82, however, very close to the threshold.

As we said it is a touchscreen panel that supports the supplied pen thanks to Windows Ink technology. Nib that I liked very much in terms of ergonomics and that offers very good feedback also in terms of performance. The tip flows very well, the reactivity of the track is good and the sensitivity to pressure levels leaves no room for criticism. The only drawback lies in the transport system of this nib. In fact, in the package there is an accessory used for this task that plugs into the USB on the right side of the laptop, thus permanently occupying the door and hindering access to the on and off button.


We close by talking about autonomy. The battery inside this Lenovo Yoga C740 is 51Wh; a not astonishing capacity but sufficient to guarantee a duration that goes beyond the average. Certainly thanks to the new Intel processors that guarantee very low consumption, but also to the absence of a discrete GPU and a fairly small display.

With standard working use under WiFi, with 50% brightness display and balanced battery settings, we are able to reach the 12 hours of continuous use. It drops to just under 11 hours if we use the notebook to watch streaming videos on Netflix, YouTube or other similar services and it goes up to just under 2 hours of use at full load.

Internet Work in Wi-Fi-8.26%12.1 hours
Netflix HD Windows Store App-9.17%10.9 hours
Rendering / Games (GTX 1050 Max-Q)-51%1.85 hours
Draining in standby (Connected Standby Off)-0.1%41 days

50% screen brightness (approx. 120 nits), 50% audio.

In the package there is a place 65W charger of fairly small size that allows you to fully recharge the battery of the C740 in stand-by in about two hours. Personally I would have used a power supply with integrated power outlet to further decrease the footprint, perhaps by slightly lengthening the thinner cable with the USB-C connector.


We are certainly faced with a good product able to offer balanced performance and important autonomy in every situation. I liked the construction, I loved the keyboard and the display too. For what are my standards of use, certainly more important than the average, there is a lack of computing power, however the C740 can be considered up to expectations if the workload is the one reported during the review.

Are there any flaws? Surely; the lack of ports is one of these, but I could say the same about the difficulty in opening the panel and the absence of a more effective cooling system or a slightly more powerful graphics card, but I think they are the necessary sacrifices to maintain an overall acceptable cost.

The model I tested has a price list of 999 euros although at the moment it is already available on the official store with a discount of 50 euros. At this price perhaps I would not buy it, but if it were to drop below the 850 euro threshold I would seriously consider it, taking into account the presence of the new processors, the very fast SSD and an excellent display I think. Even in the face of alternatives of the previous generation, a little less expensive, in fact, I would tend to choose the new one for a matter of longevity.

MediaTek Dimensity 800 is the new chipset of the Taiwanese manufacturer dedicated to medium and medium-high range smartphones. The solution, proposed almost muted during the festive days at the Product Communication Conference, it therefore goes alongside the top of the range Dimensity 1000, SoC presented at the end of November (and which we will find on Oppo Reno3 "smooth", fresh from the announcement), made with a 7nm production process and equipped with dual mode 5G modem and support for WiFi 6 .

Dimensity 800 will arrive during the first quarter 2020, and we will find it on the first devices already starting from the following quarter, therefore within the middle of the year. Unfortunately, the technical specifications of this solution are not yet known, given that the company prefers to wait for the CES in Las Vegas to reveal further details.

Here we enter the field of hypotheses: according to some sources, MediaTek Dimensity 800 will have the Integrated Helio M70 5G modem, with support for SA and NSA standards and downlink speeds up to 4.7Gbps and 2.5Gbps in uplink. The graphics processing should be entrusted to the Mali-G77 GPU.

  • 4x Cortex-A77 @ 2.6GHz + 4x Cortex-A55 @ 2.2GHz
  • dual cluster
  • Integrated Helio M70 5G modem
  • Mali-G77 MP9 GPU

To be certain, however, it is better to wait a few more days, waiting for MediaTek to officially reveal the first technical specifications. The fact remains that even the mid-range can now count on a new dual mode 5G solution, which will only contribute to an ever faster spread of new generation networks on the market.
