threaded and multi-threaded performance.
(The former accounts for most office
productivity tasks, while the latter comes into
play for image processing and rendering.)
To see how laptops fare under sustained
workloads, we encode a large video file with
the free HandBrake utility. Again, the C940
got the job done faster than nearly every
laptop with a comparable CPU, save for MSI’s
GS65 Stealth 9SD.

benchmarks: The Yoga C940 15 breezes through
productivity tasks.another look at how the Lenovo Yoga
C940 15 zips through work tasks. Any
score over 2,000 is satisfactory, so the
Yoga C940 15’s score of 3,927 keeps you
well above the baseline.
The Lenovo Yoga C940 uses the Max-Q
version of Nvidia’s GeForce GTX 1650
graphics card, which balances performance
with the thermal challenges of thin-and-light
designs. As such, laptops with standard GTX
1650 GPUs fare a bit better. In 3DMark’s
TimeSpy benchmark, for instance, the C940
fell markedly behind Dell’s XPS 15 7590 (go.
