Lenovo Yoga C740 15 review: How does it compare to the 14-inch Yoga C740?
Source: Windows Central
I recently reviewed Lenovo's xiv-inch Yoga C740, a mid-range convertible alternative to the loftier-end Yoga C940. In my review, I noted its solid aluminum design, robust audio from height-firing speakers, and splendid functioning from the tenth Gen Intel Core "Comet Lake" processor (CPU). Following the review, I got my hands on the larger 15.6-inch Yoga C740 sibling that shares a lot of traits with the smaller version. Information technology'south not just a larger version of the aforementioned laptop, nonetheless, and there are some things yous should know.
15-Inch Convertible

Bigger screen, more keyboard
Bottom line: The 15-inch Yoga C740 is correct for anyone who absolutely needs the extra screen space and HDR back up, though the 14-inch Yoga C740 is no doubt going to be improve for near people.

Lenovo supplied Windows Cardinal with a review unit of measurement of the 15-inch Yoga C740 complete with 10th Gen Intel Core i7-10510U CPU, 12GB of DDR4 RAM soldered to the board and a 512GB M.2 PCIe solid-state drive (SSD) with integrated 32GB Intel Optane retentivity. It has an upgraded bear on brandish with FHD resolution, 500 nits brightness, and Dolby Vision HDR400. This exact configuration costs most $970 from Lenovo. That'southward about as premium every bit this laptop gets, unless you add upward to 16GB of RAM, a 1TB SSD, and an active pen.
To compare prices, a xiv-inch Yoga C740 with the same CPU, SSD, and RAM — though with an FHD touch display that tops out at 300 nits — costs about $920 from Lenovo. It's not a huge cost difference, but it is something, especially when we begin to look at what's on offer with the fifteen-inch option.
Here's a detailed breakdown of the specs found within the 14- and 15-inch Yoga C740 review units.

Comparing Lenovo's Yoga C740 14 and C740 15
The 14- and 15-inch Yoga C740s share the same solid aluminum chassis with house dual-hinge design. They're well-nigh physically identical on the outside save for the size and port placement. The C740 xv weighs more than a pound over what the 14-inch model weighs; starting at iv.19 pounds (1.96kg), it'south not the amend choice for anyone who wants to have their laptop everywhere. This is a convertible, so there'south also the matter of using it as a tablet. Weight and size make information technology a bit unwieldy, but it excels in stand mode.
The left side of the Yoga C740 fifteen has two USB-C ports (one used for charging) and a 3.5mm sound jack. On the right side are two USB-A ports, one more than the 14-inch Yoga C740 offers. That'southward particularly welcome if you lot hate using a docking station and want to connect multiple accessories. Nonetheless, both laptops will work with a powerful dock that relies on USB-C connectivity.
Opening the hat, yous're treated to a total-size keyboard with number pad, sizeable Precision touchpad, and a fingerprint reader for Windows Hello. The touchpad is the same size equally on the 14-inch model, so it doesn't seem equally large, merely its drinking glass surface still tracks perfectly. The fingerprint reader is well out of the way, significant you lot won't feel information technology rubbing nether your palm while typing. For some added privacy, there is a shutter for the 720p front-facing camera above the display.
With a full keyboard and larger HDR display, the Yoga C740 fifteen makes for easy productivity work.
Other than the number pad, which isn't present on the fourteen-inch Yoga C740, the fifteen-inch model'southward keyboard has some different sized keys. Tab, CapsLk, Shift, and Ctrl on the left side have all been shrunk down, too as the Backspace key. Yous will go used to it, and the number pad is undoubtedly a benefaction for productivity, just I prefer the C740 14's key sizing.
To make room for the number pad on the 15-inch model, the speakers have been relegated to the bottom of the chassis. You still get Dolby Atmos for a nice heave, and the sound is total and loud, only the peak-firing speakers along the side of the keyboard on the 14-inch model practise a far better job in notebook mode. Using the Yoga C740 15 in stand style (where the bottom of the laptop is facing up), however, doesn't upshot in the aforementioned muffled audio as you become on the C740 14.

The 15.half-dozen-inch FHD display is available in either anti-glare IPS with 250 nits brightness or IPS sleeky with 500 nits brightness and Dolby Vision HDR400. The review unit has the latter brandish (which tacks on about $100), and it'southward totally worth the coin if you have room in your budget. I noted in the C740 xiv review that its 300-nit brandish was often challenging to run across in a well-lit room, merely that's less so in the 15-inch model cheers to the increased effulgence. I saw nigh 550 nits at maximum brightness in my testing.
I tested color with a SpyderX Pro colorimeter and got back 95% sRGB, 72% AdobeRGB, and 73% DCI-P3, all solid results at this price point. The brandish works with an active pen like Lenovo's Active Pen 2, though one wasn't included to examination. Neither laptop is available in 4K, and neither comes with the selection to add a dedicated graphics bill of fare (GPU). For those types of specs, yous'll have to bank check out something like the premium Yoga C940.
Getting into performance, both laptops come with a lot of the aforementioned available hardware. These are machines built for rather heavy productivity workloads, though the lack of dedicated GPU means you'd have a hard time getting into whatever specialized work. Both have RAM that's soldered to the board, though you lot can upgrade the SSD subsequently purchase. Both laptops also seem only to offer Wi-Fi 5 connectivity.
The C740 15 has a larger 60Wh battery compared to the 51Wh battery in the 14-inch C740, balanced by the larger display and upped brightness. Like the C740 14, the xv-inch model saw about half dozen hours of bombardment life on a charge at virtually sixty% brightness. Information technology does offer Rapid Accuse and so that y'all tin can gain back well-nigh 80% life in an hour. I ran some synthetic benchmarks to see precisely how performance stacks up.

The tenth Gen Core i7 CPU gets an excellent single-core score, though its multi-cadre score falls short of the 10th Gen Intel Cadre i5 CPU establish in the 14-inch C740. This could have to do with a chip of thermal throttling, or it could be simply the CPU itself.

The K.ii PCIe SSD here is extremely slow and doesn't come shut to comparing to the fourteen-inch model. Manufacturers generally have to utilize whatever SSD they can source, so hopefully, this isn't an event seen in all 15-inch C740s. In any case, y'all can swap out the SSD after buy.
Should you buy Lenovo's Yoga C740 xv?

The Yoga C740 15, thanks to a larger brandish and full keyboard with a number pad, is a improve fit for anyone with heavy productivity in listen. It's non as portable, nor does it brand as skilful of a tablet as the 14-inch version, but it's still a sleek aluminum convertible that's undeniably well built. The selection to upgrade the display to 500 nits brightness with Dolby Vision HDR is no dubiety also going to be attractive for a lot of people.
However, the 14-inch Yoga C740 does brand a better all-around convertible laptop. Its display isn't as impressive, and information technology lacks the actress USB-A port, but its top-firing speakers, keyboard layout, and smaller size were preferable. Both laptops are priced quite competitively, coming in well beneath $1,000 to start. If you're searching for something more in the premium vein, be sure to have a look at the Yoga C940 with dedicated GPU, 4K touch display, and soundbar hinge.

Information technology's by pattern, sure, but at that place's a distinct lack of firearms in Dying Light 2. For better or worse, mod medieval Villedor is a place to build your own weapons. Merely what happened to the guns and ammo and might it ever make a comeback?
