Lenovo now offers two sizes for its refreshed Yoga C940. The 14-inch version doesn't have a dedicated GPU or number pad, but it does include up to a 10th Gen Intel Core i7-1065G7 CPU and 4K touch display with HDR400. It's a more affordable choice for anyone who doesn't need the extra performance found in the 15-inch model, including dedicated NVIDIA GTX 1650 GPU and up to 9th Gen Core i9-9880H vPro CPU.

Features and design

The 14-inch and 15-inch Yoga C940 models are quite similar despite the size difference. Both have a unibody aluminum design with a convertible hinge that allows you to rotate the touch display around for tent, stand, and tablet modes. The hinge doubles as a soundbar, pumping out robust audio, whether you're using the device like a tablet or notebook.

There's no IR camera available on either model, but both laptops do have a sort of reverse notch above the display that offers enough space for a 720p front-facing camera and privacy shutter. To help with security, both come with a fingerprint reader built into the right-hand palm rest. The keyboard is essentially the same on both models in terms of comfort, but only the 15-inch Yoga C940 offers a full number pad for improved productivity. Both laptops come with a sizeable Precision touchpad.

Ports are the same on both laptops, with two Thunderbolt 3, one USB-A 3.1, and a 3.5mm audio jack. That's not exactly a generous selection, but it gives you the option to connect a powerful docking station if you're looking to set up a workstation. Along the side of the laptop is also a built-in silo for the active pen. It pulls out easily, and when it's inside the silo, it's charging for the next use.

Display and inking

Both the 14-inch and 15.6-inch display available here are touch and compatible with the included active pen. You get a solid inking experience from either model, and the ability to use the laptops as tablets adds to the versatility.

The 14-inch display comes in either FHD anti-glare with 400 nits brightness, FHD glossy with 400 nits brightness, FHD anti-glare with 500 nits brightness, or UHD 4K glossy with HDR400. For the best picture possible, you'll want to go with the 4K option, but keep in mind the price will rise, and battery life will drop accordingly.

If 14 inches isn't big enough, the 15.6-inch model should satisfy. It comes in two flavors based on which resolution you need. Both the FHD and 4K versions offer VESA-certified HDR400 with Dolby Vision and up to 500 nits brightness. Both are glossy, so if you need anti-glare you'll likely want to go with the 14-inch model. In either case, you're getting a beautiful display, but the larger model will make substantial productivity just a bit easier thanks to the increased screen real estate.

Performance and price

The 15.6-inch Yoga C940 starts at a higher price than the 14-inch model, but along with the larger display and chassis, it's also sporting some performance hardware. Included is up to a 9th Gen Intel Core i9-9880H vPro CPU, and all models come with an NVIDIA GTX 1650 dedicated GPU with 4GB of VRAM. It's much better cut out for tackling some specialized work, including gaming and editing, and the larger 68Wh battery helps with life between charges. You can add up to 16GB of DDR4 RAM and a 2TB M.2 PCIe solid-state drive (SSD) to round things out. The high-end 15.6-inch model costs about $2,700, while a model with 9th Gen Intel Core i7-9750H CPU, NVIDIA GTX 1650 GPU, 12GB of DDR4 RAM, and 256GB SSD costs about $1,610.

The 14-inch Yoga C940 costs considerably less than the larger model, but it doesn't have a dedicated GPU. It's instead using integrated Intel Iris Plus graphics that come with 10th Gen Intel Core i5 or i7 CPUs. Overall performance won't quite match up to the larger Yoga C940, but the smaller model is still ideal for productivity work. Add up to a 2TB M.2 PCIe SSD and 16GB of LPDDR4x RAM. Both laptops are available with Wi-Fi 6 connectivity for fast wireless speeds, though neither has LTE available.

Introductory 14-inch models with FHD display, 10th Gen Core i5 CPU, 256GB SSD, and 8GB of RAM cost about $1,150, while high-end models with Core i7 CPU, 4K touch display, 16GB of RAM, and 1TB PCIe SSD cost about $1,830. If you don't need a dedicated GPU or the larger display, you can deck out a 14-inch C940 for about the same price as the introductory 15.6-inch model.

The 14-inch Yoga C940 is a better option for most people

Due to the lower price and overall stellar construction, the 14-inch Yoga C940 should appeal to more people. As long as you don't need a dedicated GPU or Core i9 performance, the smaller model offers better mobility and will still keep up with any task you throw its way, as long as you're not interested in intensive specialized work.

Need boosted performance from a dedicated GPU? Want a more substantial touch display with HDR400 and Dolby Vision? The 15.6-inch Yoga C940 will cost more, but it does deliver impressive specs.
