less powerful
than my Lenovo P50 laptop which has an Skylake i7 (Xeon capable), 16GB ram (64GB capable), and 2TB of SSD (1TB SATA 2x512GB NVMe), and Nvidia M2000M 4GB GPU, running Linux Mint 17 MATE.
My laptop is a bit bigger(14.86" x 9.93" x 0.96-1.16") probably because it has to include a full sized keyboard and 15.6" LCD.
Though I'm assuming it's cheaper than my $3400 laptop(probably doesn't include a 4k screen by default even though I run mine in 1080p). I don't see pricing for this new HP thing anywhere.
I love HP Proliant and 3PAR though this workstation doesn't seem like much of a workstation if a basic laptop easily out classes it. (I have a HP xw9400 workstation next to me here though it is about a decade old, by no means is it small though).
per above poster my laptop is pretty quiet and comes with a 170W external AC adapter.
