Lenovo Yoga C740 14 review - calderaedwasind
The Lenovo Yoga C740 14 is one of the about impressive 2-in-1 laptops we've seen in its price range. Weighing in at clean three pounds and jammed with nifty features, the little, sturdily built, Yoga C740 packs in plenty of productivity pep, and it lav shoemaker's last the whole Day without its AC adapter. A coruscant, Dolby Vision-enabled display plus Dolby Atmos sound furnish pile of eye and ear candy. A physical tv camera shutter (which, regrettably, is a teensy-weensy hardened to slide open and closed) and a fingerprint lecturer help to bolster surety.
In a world where in high spirits-end laptops no one can open get all the attention, and budget laptops can be a pail of compromises, it's nice to see a middle-priced laptop that has so much going for it. The Lenovo Yoga C740 well earns our Editor's Option award.
This review is part of our ongoing roundup of the best laptops. Go there for info on competing laptops and how we reliable them.
Configuration
Lenovo offers three SKUs for the Yoga C740, ranging from the model we tested (currently $790 connected Lenovo.com) to a high-last $1,010 configuration. Our brush up unit comes with a 10th-gen, quad-core Intel Core group i5-10210U Comet Lake processor (which is built on the older 14nm computer architecture ground in Intel's 8th- and 9th-gen CPUs, versus the 10nm chips in Intel's more powerful Ice Lake lineup). Lease's take a closer look at the specifications of our particular Yoga C740:
- CPU: Quad-core Intel Burden-i5 10210U Comet Lake C.P.U.
- Drive: 8GB DDR4 RAM
- GPU: Integrated UHD Art
- Display: 14-inch 1920×1080 IPS touchscreen with Ray M. Dolby Vision HDR
- Storage: 512GB SSD PCIe
- Networking: Wi-Fi 5 (802.11ac)
- Dimensions: 12.67 x 8.54 x 0.67 inches
- Weight: 3 pounds (Oregon 3.75 pounds with power brick)
The pricier $880 and $1,010 SKUs each boast Core i7-10510U Comet Lake chips, 8GB and 16GB of RAM, and 512GB and 1TB SSDs, respectively. All iii laptops get equipped with 14-inch full-HD touchscreens that feature Dolby Visual sense HDR, which is designed to turn in high-demarcation images.
Overall, our Yoga C740 unit is a pretty coagulated configuration for a $790 arrangement. While the quad-core Comet Lake CPU doesn't offer a impressive boost concluded early-gen Whiskey Lake chips, it should still bear much enough horsepower for everyday computing inevitably, on with some added oomph for video encoding and other processor-intensive activities. The 8GB of RAM is standard for a laptop in this price range and should help to smooth all over some multitasking bumps, spell the 512GB SSD is roomy enough to install raft of apps along with a modest media collection. The full-HD display should have spacious viewing angles thanks to its IPS (in-plane switch) technology, while the Dolby Vision HDR should give visuals some added pop.
We'rhenium also impressed that this 2-in-1 laptop weighs single ternion pounds. We in the main expect look-alike-sized convertibles therein price chain to weigh nigher to four pounds.
Design
Lenovo sticks with the dependable when it comes to the Yoga C740's design. The update boasts the identical smooth, fingerprint-resistant eyelid and tapered left and right sides as previous Yoga models. Naturally, the C740 also boasts the familiar Yoga 360-degree flexible joint, which lets you pivot the laptop's display all the way around for tablet use, bivouac it along a tabletop, or place it with the keyboard facing kill and the cover tilted up.
Ben Patterson/IDG The Lenovo Yoga C740's 360-academic degree hinge lets you swivel the showing all the way around for tablet use, or you give the axe tent the laptop on a savorless come on.
The Yoga C740's aluminum chassis has a sturdy, premium feel for. The power push sits on the right side of the laptop up near the hinge, making information technology difficult to fourth estate by accident. The left, ripe, and top bezels of the C740's anti-glare expose are relatively hyperfine, although the posterior bezel is (typically) somewhat thicker.
Speaking of the display bezels, the 720p webcam that's embedded in the top bezel sports a physical "TrueBlock" privacy shutter, a handy concealment feature article that we Don River't imag often on laptops in this price chain. However, I had a tough time getting a clutch connected the tiny switch that slides the shutter (those with longer fingernails will have finer luck), and there are no obvious visual cues that let you know whether the shutter is in its open or unsympathetic position.
Ben Patterson/IDG The Lenovo Yoga C740's personal camera shutter is a W. C. Handy privateness feature, just the tiny notch privy exist tough to slide.
Display
The Yoga C740's full-HD and touch-enabled showing is one of its best features. First, it's relatively beaming, measuring more than 350 nits (or candelas) according to our readings. That's well above our minimum 250-nit canonic for optimal interior viewing, and a welcome surprise given the C740's sub-$800 price tag end. The IPS expose also (and unsurprisingly) boasts impressive viewing angles, with the silver screen dimming only if a tad when viewed from the lateral or from in a higher place operating theater below.
Even better, the C740's display supports Dolby Imagination, a kinetic HDR format that allows for vivid color and deep, dark black levels when you'atomic number 75 watching verified content. Taking a gander at the Dolby Vision-enabled Altered Carbon on the Netflix app for Windows, the dark, inclement landscape of the futuristic Bay City contrasted impressively with the bright blue sky above the clouds. You can also listen in Dolby Atmos over the Yoga's coordinated speakers (which we'll cover in a moment).
Keyboard, trackpad, speakers, and extras
I thoroughly enjoyed my time typing happening the Yoga C740's comfy, backlit keyboard. Lenovo sagely opted not to squeeze a dedicated quantitative keypad following to the main keyboard, so information technology boasts convenient, easy-to-discover keys with a generous amount of travel and tactile feedback. Piece the keyboard lacks media shortcuts, you ut set about shortcuts for muting the microphone and electronically disabling the camera.
Ben Patterson/IDG The Lenovo Yoga C740's backlit keyboard has a roomy, premium feel.
I was also a fan of the Yoga C740's smooth, responsive trackpad. While the trackpad (per usual) requires a bazaar amount of pressure to click, it did a great job of rejecting false inputs, with the cursor never jittering unless I deliberately dragged my palms across the trackpad's surface (and level then, I had to bring off at it).
Beneath the bottom-right box of the keyboard sits a Windows Hello-enabled fingerprint reader, handy for unlocking Windows and logging into Windows Hello-compatible apps. I used the fingerprint reader throughout my examination, and it managed to make out my fingerprint nearly all time.
The Yoga C740's up-firing off speakers sounded very much amend than your average laptop speakers, with relatively crisp and elaborate audio frequency that boasts a light dusting of deep. The speakers besides feature support for Dolby Atmos, an object-based 3D sound format that's been display up in an increasing number of laptops, phones, and tablets. You can use the Dolby Atmos app for Windows to tailor-make the audio effects, with a "dynamic" setting studied to pick the best preset based happening the substance you're listening to. Even with their Atmos abilities, withal, the C740's integrated speakers can't match the sound quality of a pair of decent headphones or a set of extraneous speakers.
Ports
The Yoga C740 is a tad chintzy when it comes to ports—and indeed, you only get three, or four if you include the audio jackstones.
On the left side of the Yoga C740, you get two USB 3.1 Gen 1 Typecast-C ports, which both support Power Rescue piece doubling as DisplayPorts. Also connected the far left go with is the aforementioned jazz group audio jack.
Ben Patterson/IDG The left side of the Yoga C740 has two USB 3.1 Gen 1 Character-A ports and a combo audio jack.
On the right position, you get a single USB 3.1 Gen 1 Type-A port, which sits side by side to the Yoga's power button.
Ben Patterson/IDG The merely port connected the redress side of the Yoga C740 is a USB 3.1 Gen 1 Type-A port.
And…that's pretty much it. While it's always nice to get deuce USB-C ports, keep in mind that you'll penury to use one of them to plug in the enclosed USB-C charging wire. Otherwise, you're left with the one USB Type-A port. You'll likely need a hub if you're planning on plugging in multiple accessories with legacy USB connectors, and you'll have to do without an HDMI port or a media batting order referee.
Functioning
For our benchmarking charts, we've alveolate the Lenovo Yoga C740 against a mix up of quad-core laptops, most of which are powered by older 8th-gen Whiskey Lake chips, while one sports a spiffy new 10th-gen Sparkler Lake CPU. We also tossed in a budget dual-core organization and so you can examine the diverse quad-core makes (and why dual-core is still sufficient for umteen uses).
As you'll see in our results, the Lenovo Yoga C740 verified to be a hard and reliable performer both in footing of informal PC chores also as tougher multi-core tasks. We were particularly impressed with its bombardment life.
PCMark 8 Work Conventional
We'll originate in our performance examination with PCMark 8, a benchmark that simulates so much daily computation activities as net browsing, building spreadsheets, social networking, and television chat. Because most of these tasks requireonly a single Processor nucleus, a laptop with a six-core processor won't necessarily delight an reward over a dual-essence laptop. A PCMark 8 score of 2,000 or high means you can await silky-smooth Office performance.
Ben Patterson/IDG The Lenovo Yoga C740 tops our PCMark 8 benchmarking chart, which means you should expect smooth performance for everyday computing tasks.
As you nates hear in our performance chart, the Lenovo C740 leads the pack, although to be fair, all of the laptops in our roundup managed to snag excellent PCMark 8 dozens, including even a dual-core Acer Aspire 5. While IT may look surprising that a quad-core, Core i7-packing HP Begrudge 13 sits at the bottom of our chart, that's likely because its thin and bomber-three-pound design demanded dialing down its performance a shade—and even then, it still passed the 3,000 sucker in PCMark 8 with room to spare. Bottom line: Altogether of the laptops in our comparison are great everyday computing performers.
HandBrake
A substantially more demanding benchmark than the relatively easy-sledding PCMark 8, our future test involves using the free HandBrake utility to exchange a 30GB MKV register into a initialise suitable for Android tablets. It's a multi-heart and soul, CPU-intensive, and somewhat prolonged (as in an hour or Sir Thomas More) task that tends to twisting up chilling fans. The laptops with the almost processor cores generally snag the best scores.
Ben Patterson/IDG The Lenovo Yoga C740 is in a virtual three-room tie for third place in our CPU-intensive HandBrake test, but its performance still lands in the pep pill range of our expectations.
While the Yoga C740 fell to fifth place in our comparison graph, a closer look reveals a virtual 4-way tie for second place, with a mere atomlike more or less separating the H.P. Envy 13 with its Core i7 CPU and the Yoga C740. Way in reply in endure lay out is the two-fold-core Acer Aspire 5, which serves to demonstrate the leap in public presentation of a quad-core CPU over a dual-core system of rules in HandBrake-type, qualifier tasks.
At any rat, the Yoga C740's HandBrake performance lands in the upper range of our expectations, and that's a good thing. It's also valuable noting that while many laptops with older, quad-nitty-gritty Whisky Lake CPUs hollering their fans alike jet-propelled plane engines during the HandBrake test, the C740's temperature reduction fans never rose above a gentle purr.
Cinebench
Our next benchmark is some other CPU-crushing test, but unlike the (typically) 60 minutes-long HandBrake benchmark, Cinebench—which involves rendering a 3D image straightaway—is generally o'er in a matter of minutes. So patc HandBrake tells USA how a given laptop handles heavy processor lashing terminated a long run, Cinebench offers a snapshot of a laptop's CPU and thermal performance during short bursts of immoderate activity.
Ben Patterson/IDG The Lenovo Yoga C740 finished in the tip triplet for our totally-threads Cinebench tests, which measures a laptop computer's performance under concise but violent Processor oodles.
Look at our chart, the Yoga C740 comes in at a very sizeable third place, behind the Core i7-powered HP Envy 13 (which boasts a 4.6GHz encourage clock, versus 4.2GHz for the Yoga C740) and the quad-core Lenovo IdeaPad S340 (a Whiskey Lake laptop computer that's consistently punched above its weight). Trailing the Yoga C740 are quartet more Whisky Lake laptops with sub-600 multi-thread Cinebench scores (which is more distinctive for 8th-gen Kernel i5 systems), while that dual-core Acer Aspire 5 unsurprisingly waterfall into parthian place.
Besides the multi-threaded Cinebench results, we also consider the single-thread scores to gauge the efficiency of a laptop's sole-core performance. Once more, the Yoga C740 snags a solid third-place score (tying with the HP Pavilion x360), trailing the Center i7-powered HP Envy and the Acer Swift 3, a thin and light budget laptop high-powered aside a Meat i5-1035G1 Sparkler Lake CPU.
3DMark 8 Sky Diver 1.0
For graphics performance, we address 3DMark 8 Sky Diver 1.0, a benchmark designed to test the performance of gaming laptops. With its integrated Intel UHD Graphics CORE (which is basically combining weight to the UHD Artwork 620 cores in 8th- and 9th-gen Intel CPUs), the Yoga C740 is no gaming laptop, but we're still interested in seeing how its visuals stack up against those of its competitors.
Ben Patterson/IDG While it's no gaming laptop, the Lenovo Yoga C740 hush up managed a respectable tally in 3DMark 8, a bench mark that measures graphics performance.
Once again, no surprises, with the Yoga in a virtual three-way tie with a pair of laptops (the Lenovo IdeaPad S340 and the Essence i5-powered Acer Aim 5) that some feature interracial UHD Art 620 cores. The C740's 3DMark 8 Sky Diver score is actually in the top scope of what we'd expect, good for light gaming (as in cheat and Minesweeper, non so much Fortnite) and casual photograph and video editing.
Near the top of the chart is the Acer Western fence lizard 3 and its upgraded Intel UHD Graphics G1 core. Leaping ahead of the eternal sleep is the H.P. Envy 13 and its separate Nvidia GeForce MX250 graphics card, which goes to show the difference that a separate GPU can make in terms of written operation.
Battery life
We mental testing the stamp battery life of a laptop by iteration a 4K video using the stock Windows Movies & TV app, with screen brightness nonmoving to most 250 nits (which meant turning the Yoga C740's brightness setting down to 91 per centum) and dialing the volume to 50 percent, headphones along.
Ben Patterson/IDG Thanks to its impressive battery life, you can leave the Lenovo Yoga C740's top executive transcriber at home if you're taking it for a day get off.
The results speak for themselves. The Yoga C740's 654 minutes (nearly 11 hours) handily dusts its competitors when it comes to its on-battery performance. IT's worth noting that the Yoga C740's 51 watt-time of day barrage isn't yet the biggest in the bunch—that distinction goes to the HP Envy 13, which landed a distant fifth in our graph (the Invidia has A battery-draining 4K display). CPU-intense tasks such as video encoding will put through a of import dent in battery public presentation, but the Yoga C740's result means you can probably leave its Actinium adaptor behind if you'Re winning it on a day trip.
Buns line
For its hoagy-$800 price, the Lenovo Yoga C740 ranks among the most impressive 2-in-1 laptops I've ever tested, complete with a bright, heart-pop screen, a slight and lightweight design for a convertible laptop, solid CPU performance, and impressive battery life. Heck, even its built-in Dolby Atmos speakers are pretty good for laptop computer speakers. If you're shopping for a 2-in-1 laptop below $1,000, the Yoga C740 would be a astute choice.
