AMD 4700S SoC Desktop Motherboard Pictured

Pictures of the mysterious AMD 4700S SoC desktop kit just hit the web, courtesy Disclosuzen. As we reported earlier, the 4700S could be derived from the semi-custom SoC AMD originally co-developed with Microsoft for the Xbox Series X/S consoles. Close-ups of the PC motherboard reveals an interesting aspect—the board lacks any discernible display output, and instead relies on a PCI-Express graphics card. The board is built in the Mini-ITX form-factor, and draws power from a conventional combination of 24-pin ATX and 8-pin EPS power connectors.

A custom-design fan-heatsink cools the SoC. There are no memory slots, an unknown amount of hardwired memory under the SoC heatsink. 6-channel HD audio, wired Ethernet, and twelve USB ports (six each of USB 3.x and USB 2.0), make for the rest of the I/O. Storage connectivity is interesting—there are no M.2 NVMe slots, just two SATA ports. Why AMD even came up with this contraption is anyone's guess, but we guess it serves two purposes—1, it lets AMD harvest dies with faulty iGPUs, and 2, it serves as a decent developer platform, for game devs to at least optimize for the CPU. The lack of any NVMe storage interfaces points to the likelihood of this board not being meant for the general audience. Retail channel availability of the board seems unlikely, although it won't surprise us if suppliers on AliExpress list it anyway.

Thin clients with a very low power GPU with better than average video acceleration options for digital signage, a training room to run multiple monitors and a primary video screen.

No memory slots or any mention of soldered RAM.

Based on the CPU backplate I'd say it's soldered on and uses the backplate as a heatsink.

You can see the obverse of the memory pads on each side of the CPU at the top of the board.
Looks like eight chips in total.
