Over ten hours of battery life

is perfectly acceptable for the

HP Spectre x360 15, though

it’s still outmatched by Dell’s

offering. Dell’s panel is only

1080p, however.

There’s a great deal of

variance in these 3DMark

comparisons, mainly due to

the GPU. This result indicates

that the Spectre x360 15

(2019) performs close to what

you’d expect from a premium

content-creation PC, without

quite reaching gaming-PC

status.

For an evaluation of the

GPU, we turn to the

3DMark tests. Our tests

typically use the Sky Diver

DirectX11 test, spanning a

range of notebooks. We

also directly compared the Dell XPS 15 9570

and HP’s Spectre x360 15 in a more advanced

benchmark, Fire Strike, which we normally

use with gaming PCs. Here, Dell’s XPS 15

(score: 6,881) is 4

percent better than the

tested Spectre x360

(score: 6614).

Finally, there’s battery

life. We would expect a

discrete GPU and 4K

screen to crimp battery life

roughly 90-minute movie is excellent, both
from a relative performance standpoint as
well as a practical use of the Spectre’s
computing power.
