The specifications of the AMD B550 chipset appear, a somewhat simpler version than the X570, losing the PCIe 4.0 x16 interface.
Users have long been requesting a simpler chipset for AMD Ryzen 3000 processors. The X570 chipset is the most powerful solution, but the company is now finalizing the B550 chipset. This chipset shares many similarities with AMD's current chipset, but lacks the PCIe 4.0 x16 interface. This isn't a major loss, as interest in the PCIe 4.0 interface appears to be quite limited.
The new B550 chipset will mainly be intended for the Ryzen 3 and Ryzen 5 ranges. Motherboards with this chipset will in principle be cheaper and also simpler. You may also miss the chipset fan, being a simpler solution.
AMD B550 chipset specs released
Perhaps one of the most interesting parts is that it offers us two USB 3.2 Gen2 @ 10Gbps and six USB 2.0. This AMD B550 chipset offers us four SATA III @ 6Gbps ports. The connectivity between chipset and processor is reduced to a PCIe 3.0 x4 interface, reducing the bandwidth a bit with respect to the X570 chipset.
Despite the loss of support for the PCIe 4.0 interface, not many users want it on their system. Additionally, the graphics card market is not getting the most out of this type of interface.
The interesting part is that the PCIe 4.0 interface for M.2 SSDs will be kept. It will allow us to install an SSD drive on a motherboard and get a little extra performance. These new motherboards could hit the market next October.
If they arrive in October they could match the recently leaked Ryzen 5 3500 and Ryzen 5 3500X processors. We don't have any news about the Ryzen 3 processors yet. Possibly because of TSMC's problems to manufacture processors for AMD, the low-end is delayed a lot, if they end up reaching the market.
