Ubuntu-based Pop!_OS (made by System76) aside, the HP Dev One is built around a 14-inch 1920x1080 screen with 800-nits of maximum brightness, packed in a 0.75-inch chassis.
HP went for AMD's Ryzen 7 Pro 5850U, a 15W 8-core/16-thread Zen 3 CPU with 4MB of L2 and 16MB of L3 cache, running at 1.9GHz base and up to 4.4GHz maximum boost clock. It has Radeon RX Vega 8 graphics with 8CUs, running at up to 2000MHz.
HP has paired the AMD CPU with 16GB of DDR4-3200 memory, upgradable to 64GB, and 1TB of PCIe 3.0 x4 SSD storage. The battery, which should keep it alive for around 12 hours, is a 3-cell 53Whr one. It also gets a 720p webcam, ambient light sensor, stereo speakers, dual multi-array microphone, Realtek's RTL8822CE 802.11a/b/g/n/ac (2x2) Wi-Fi and Bluetooth 5, glass clickpad with gesture support, HDMI 2.0 output, two USB-C and two USB-A ports.
There is also an optional HP Dual Point Backlit spill-resistant Premium Keyboard with the "Super Key", something developers coming from Linux would surely appreciate.
The HP Dev One starts at $1,099 and is currently available for purchase only in the US. HP has made a dedicated HPDevOne.com website where you can check it out and order the laptop.
