Over the past few months we have seen increasing adoption of AMD Ryzen processors by makers of ultra-compact form-factor (UCFF) desktops. At present, the number of UCFF systems powered by AMD’s Ryzen is not large, but it is growing. On Tuesday HP announced its first small form-factor commercial desktop powered by AMD’s Ryzen Pro 2000-series.

Measuring 177×175×34 mm and weighing 1.26 kilograms, HP’s ProDesk 405 G4 is among the most compact desktop computers based on AMD’s Ryzen available today. The machine can pack AMD’s quad-core Ryzen 5 Pro 2400 GE processor with Radeon Vega 11 graphics that can be paired with up to 32 GB of DDR4 memory, an M.2 PCIe/NVMe SSD and a 2.5-inch HDD. The system consumes up to 65 W of power supplied by an external power brick.

Connectivity-wise, the ProDesk 405 G4 provides an 802.11ac + Bluetooth controller (from Intel or Realtek), a gigabit ethernet port, six USB 3.1 Gen 1 ports, a DisplayPort 1.2 with MST, and optional connectors (including USB 3.1 Gen 2 Type-C, HDMI 2.0, D-Sub, Serial, etc.) based on the specific sub-model.

    I will nave buy hp prodisk 400 g2. Vey bad experience. I am using these computers in IT labs in diffrent schools. In each school lab 15 computers in which almost half of computers have bios issue.

    I put 20+ of the elitedesk 800 in a computer lab and they've worked wonderfully. Wonder if the 400g2 had specific issues or a bad bios update or ?

    Oh gosh, that's an adorable little PC! I'm not all that interested in desktops these days, but this one is cute and it gets around Ryzen's awful idle power management problems in notebooks simply by being chained to an outlet where its a non-issue.

    Nice PC for a nice price but it's kind of ugly to me. I think it would look a lot better if they went with the HP Spectre design language.

    I'm glad they went the direction they did. I find the Spectre aesthetic, especially the newer ones, quite gaudy.
