Be warned, however: If you opt for the 4K display (which has four times as

that you’ll get 15 unplugged hours with the 1080p screen and half that time with
the 4K upgrade. As you’ll see in the next section, our test results are in line with

any USB Type-A ports. Dell helps ease your transition from USB-A to USB-C by
including a dongle with the XPS 13, but it’s BYOD (bring your own dongle)
when you need to connect USB-A peripherals to the IdeaPad S940.
SUFFICIENT, IF A STEP BEHIND
For our benchmark tests, I matched the S940 against four other high-end
ultraportables, three of which—the above mentioned VAIO and Dell, and the
Asus ZenBook 14 (UX433F)—feature the same Core i7-8565U processor.
A member of Intel’s 8th Generation Core chip family, the CPU has four cores,
eight processing threads, a base frequency of 1.8GHz, and a max turbo
frequency of 4.6GHz. The Acer Swift 7 features the Core i7-8500Y, a 1.5GHz
dual-core chip that draws only 5 watts to the Core i7-8565U’s 15 watts. All the
systems here feature 16GB of RAM, Intel integrated graphics, and either a
512GB or 1TB solid-state drive.
