Economical AMD B550 chipset-based motherboards with PCI Express 4.0 support should go on sale starting June 16, 2020. Retailers should already restock, and some of them have already released new items in their stores. Online: Motherboards are available to order, for example in Australia, from the official Interconnect IT Solutions distributor.
The Australian retailer posted on its website three models of the motherboard: ASUS ROG Strix B550-F Gaming (Wi-Fi), TUF Gaming B550M-Plus (Wi-Fi) and Prime B550M-A – all three at a price equivalent to 153 US dollars each. Given the different position of the models, Asus is unlikely to evaluate the trio equally. It is important to understand that this is only a pre-order, and the store could only set preliminary prices so far.
For reference, the current ASUS ROG Strix B450-F Gaming and TUF B450M-Plus Gaming motherboards on the AMD B450 chipset are currently sold in the US retail market. USA For $ 130 and $ 90 respectively.
As you know, motherboards with AMD B550 will support a high speed PCIe 4.0 interface. The new bus requires a motherboard design with a wider crawl interval than PCIe 3.0. While PCIe 3.0 can transmit signals on one layer of the PCB, PCIe 4.0 needs at least six layers, which will make B550 based motherboards a bit more expensive than current B450 offerings.
