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.

    Nice! Finally mini PC with usable CPU/GPU unlike some Pentium/i3 based :-).

    There are lots of Nuc's you can get with i5 and i7's - not just Pentium/i3's.

    On CPU side- ok, but iGPU?
    Also 2400GE similar level Intel based will be much more expensive.

    Dropped decimal point

    Thickness 34 mm | 133 inches
    should be 1.33 inches

    I wish the Mac Mini had taken the Ryzen route. I'd happily sacrifice couple of CPU cores for decent graphics.

    My guess is that they are too invested in Thunderbolt, which as of now cannot be combined with Ryzen. One can hope it changes when USB4 hopefully makes it easier for vendors to integrate Thunderbolt on non-Intel systems.
