AMD launched zen 4 600 series motherboards featuring socket AM5 and 4 new chipsets. X670E, X670, B650E, and B650.
In this video we will explain the differences in the various motherboard features based on the different chipset.

For those who do not know, a chipset is a group of interdependent chips on a motherboard that control the flow of data and instructions between the CPU and external devices. It controls external buses, memory cache and some peripherals.

AMDs 600 series motherboard lineup are X670, B650E, and B650 which includes only the latest socket and memory configuration. 

These chipsets are built for Ryzen 7000 series processors recently introduced by AMD and released in late September 2022.

Each chipset is targeted at different users.

Here is a chart from AMD comparing the key features like PCI-Express, USB, and SATA ports between these different chipsets.

X670 Extreme.
This top-end option is for users who want support for future PCI-Express 5.0 capable graphics cards. This chipset is likely to be found on all the top-end motherboards tailored for PC enthusiasts and workstation users. It packs 44 PCI-Express lanes with 20 lanes capable of 5.0 speeds, 12 USB 10Gbps ports, 2 USB 20Gbps ports and 8 sata ports.
X670.
If you don't need a full complement of PCI-Express 5.0 lanes, but still want a lot of fast USB ports and SATA drive connections, the normal X670 should do the trick. It does still support one fast, N.V.M.E. Gen 5 SSD as well. It packs 44 PCI-Express lanes with 4 lanes capable of 5.0 speeds, 12 USB 10Gbps ports, 2 USB 20Gbps ports and 8 sata ports.

B650 Extreme.
This is a bit of a paradox, being an "extreme" version of a more mid-range chipset, but it might be popular with enthusiast-focused boards that are limited on space or price. It gets the same level of PCIe 5.0 support that X670 Extreme has, just with a reduced number of PCI-Express 4.0 lanes, USB and SATA ports. It packs 36 PCI-Express lanes with 20 lanes capable of 5.0 speeds, 6 USB 10Gbps ports, 1 USB 20Gbps port and 4 sata ports.

B650.
For the time being this will be the most affordable chipset option supporting Ryzen 7000, but even if a lower model comes out, this will probably be a popular choice for compact micro ATX and ITX motherboards. It is perfect for those who want the latest AMD CPUs and DDR5 memory, but who aren't concerned about support for bleeding-edge PCI-Express 5.0 devices. It packs 36 PCI-Express lanes with 0 lanes capable of 5.0 speeds, 6 USB 10Gbps ports, 1 USB 20Gbps port and 4 sata ports.
