According to VideoCardz portal, ASRock is going to show a whole bunch of new motherboards with B850 chipset for AMD processors in early January. They will be designed for Ryzen 7000 and Ryzen 9000 series models.
Erying has introduced an unusual MoTD motherboard for building gaming system units. The novelty comes with a soldered Intel Core 14th generation processor for laptops, but otherwise it doesn't differ much from traditional models with a socket for desktop chips, and costs much cheaper.
MSI announced MEG Z890 GODLIKE motherboard, which became the most expensive model in the company's portfolio. Its price is comparable to buying a ready-made ?system? capable of running any modern AAA games.
