During the Computex exhibition next week, AMD is expected to display various Am5 motherboards. However, before the exhibition, some netizens of Baidu Post Bar @ amd bar in China had shared the PCB design drawing of ASUS x670 prime x670-p WiFi.
From the position indicated by the arrow in the picture, it can be seen that Am5 encapsulated socket is used, with 4 ddr5 memory sockets and 1 PCIe x16 interface. 14 phase power supply is adopted. It is worth noting that the chipset part. It was previously rumored that the x670 would be combined by two b650 chips, but it was separated from the PCB picture. In addition to the original chipset position, there was another one under the PCIe x16 slot.
AMD's upcoming ryzen7000 Series CPU based on the company's zen4 microarchitecture will adopt a new platform with a new Am5 slot. In addition, they will also use ddr5 memory and pcie5 0 interface and many other innovations. These new platforms will require new chipsets and will initially provide three chipsets: AMD's x670, x670e and b650. It is reported that AMD's x670 relies on two identical chips, while the b650 uses only one of them. Although the functions of the two platforms should be similar (or very close), the former will support more PCIe channels, more ports, richer I / O, etc.
An interesting thing about this photo is that there is a chip between the two x670 chips. Presumably, this is a PCIe switch designed to ensure better I / O performance. Although this assumption seems logical, it should be taken into account that the goal of asus's prime motherboard is relatively cheap. Adding PCIe switches to such platforms is unreasonable unless amd wants its advanced platforms to use such switches to ensure maximum performance and reliability.
In terms of model, ASUS x670 prime x670-p WiFi should not be x670e, that is, it does not support PCIe Gen 5, but should still support gen4.
