Here is perhaps the first picture of a socket AM4 motherboard up close. The HP "Willow" is a micro-ATX motherboard custom-designed by the company to deploy on several of its upcoming desktop PC models, offered initially with AMD A-series "Bristol Ridge" socket AM4 APUs. Since this is custom-built for desktops that will probably be sold under $500, the board is built to a cost. The board features AMD A320 chipset.The picture reveals socket AM4 to have extremely fine pins, and feature a square bolt-type cooler retention mechanism similar to that of contemporary Intel sockets. It does away with the rectangular layout. The advantage of a square layout is that it allows you to orient your cooler in any direction. Since the core-logic is moved to the APU/CPU package, the remaining rump of what AMD refers to as "chipset," is just a PCIe multi-function chip that puts out additional SATA and USB ports. With its TDP under 5W, this chip can make do without a heatsink. Other noteworthy features include two DDR4 DIMM slots, a PCIe gen 3.0 x16 slot, a short M.2 slot, a couple of SATA 6 Gb/s ports, and basic connectivity.
