ASRock has introduced what could be the world’s smallest system based on AMD Ryzen processor. The 4X4 Box-R1000 ultra-compact form-factor (UCFF) PC can fit on the palm of a hand, yet it packs everything needed to run a variety of software required for digital signage, kiosks, thin clients and other applications.

Measuring 110×118.5×67.3 mm and weighing 0.7 kilograms, the ASRock 4X4 Box-R1000 is based on AMD’s dual-core Ryzen Embedded R1000-series SoC (the R1606G or the R1505G model) with integrated Radeon Vega graphics. The system can accommodate up to 32 GB of DDR4-2400 memory (using two SO-DIMMs), a 2.5-inch SATA storage device, as well as an M.2-2260 SSD featuring a SATA or PCIe 3.0 x4 interface.

When it comes to connectivity, the ASRock 4X4 Box-R1000 features two GbE connectors (controlled by the Realtek RTL8111G controllers), a Wi-Fi 5 controller (Intel Wireless-AC 3168), three USB 3.0 Type-A ports, two USB 2.0 Type-A connectors, one HDMI, two DisplayPorts, and a 3.5-mm audio connector for headsets.

While the small form-factor (SFF) 4X4 Box-R1000 can be used as a UCFF desktop PC, it is primarily aimed at embedded applications. As a result, it is equipped with a watchdog timer and is rated to run at temperatures of up to 40ºC.

ASRock already lists its 4X4 Box-R1000 systems on its website, so their release is just around the corner. Meanwhile, it is unclear when exactly the UCFF PCs will be available and how much they are set to cost.

    "ASRock has introduced what could be the world’s smallest system based on AMD Ryzen processor."

    This might actually mean something if it had a desirable Ryzen CPU.

    I assume that has to be ambient, right?
  • nathanddrews - Friday, July 5, 2019 - link

    Depending on the price, this could be a very desirable system. My head immediately goes to some sort of HTPC or arcade emulation setup, but the Pi4 is probably going to fill that void better for the majority of cases. That said, anyone know why it's called 4X4? I first misread it as being 4x4x4 inches and thought that would be cool to have a tiny cube PC, but those dimensions are impossible with this hardware...
  • Hul8 - Friday, July 5, 2019 - link

    Length: 118.5 mm = 4.67 in
    Width: 110 mm = 4.33 in
    Height: 67.3 mm = 2.65 in

    So your first take was correct - Length x Width is in the 4 inch by 4 inch ballpark. (Although Asrock have taken some liberties with the rounding.)

    I mean in such a small form factor it's not bad, you're not buying one of these to run heavy workloads. With that being said there's no reason they shouldn't at least OFFER a higher-end model with a V1605B.

    As Death said below, if you are willing to go with something slightly larger, they already have the A300 which does socketed 65W Ryzens and thus has far greater possibilities (though I would personally couple the A300 with GE chips).
  • Death666Angel - Friday, July 5, 2019 - link

    Just as a reference for people: The AsRock DeskMini A300 can accommodate a 65W socketed Ryzen CPU and has a size of 155 x 155 x 80 mm³. The R1000 has more USB and LAN ports, fewer internal specs (M.2 / 2.5"). Considering the embedded/business nature of this thing, it looks pretty good. 2 LAN ports means some enthusiasts (who aren't die hard on Intel NICs) will find a use for this thing. Personally, I'd take the A300 for a better hardware package in slightly bigger package. I like AsRock for doing these kinds of things for the consumers.

    I'm curious what the smallest viable option for a Matisse chip will turn out be. The smallest X570 board I've heard of so far is mini-DTX, and since there're no Matisse APUs, looks like it has to fit a GPU unless you're using it more like a server.
  • amb9800 - Friday, July 5, 2019 - link

    There are several announced Mini-ITX X570 boards- those are the smallest so far.
  • Alexvrb - Friday, July 5, 2019 - link

    I don't know if they sell the mini-STX board separately, but if Asrock updates the BIOS for the board in the A300, that could run 65W Matisse. They may just want to wait and release a newer model in a year instead though... the point is that mini-STX is possible.

    Mini-ITX is far more available and sensible though, and if you don't want to spend the cash on X570 there are B450/X470 and future 5xx options.
  • Death666Angel - Sunday, July 7, 2019 - link

    The mini STX needs an APU though unless you go with a PCIe M.2 to GPU hack. :)
