As you can see, the list includes ten chipsets: X870E, X870, B850, B840, X670E, X670, B650E, B650, and A620A620A. All support PCI Express 4.0 for CPU lanes, but only some are compatible with PCI Express 5.0. Some support PCIe 5.0 for both graphics and SSDs. Others only have PCIe 5.0 for the SSD slots. Other than that, the remaining differences between AMD AM5 chipsets mostly concern the number of additional PCI Express lanes, their support for the USB4 standard, and their SuperSpeed 20 Gbps, SuperSpeed 10 Gbps, and SuperSpeed 5 Gbps USB ports. Let’s take a look at them one by one and see what exactly they offer:
AMD X870E Chipset
The X870E is AMD's most powerful AM5 chipset for the Ryzen 9000, 8000, and 7000 tunisia telegram data series processors. It builds on the dual-chip design of its predecessor, the X670E, using two interconnected chiplets that communicate via four PCI Express 4.0 lanes. The X870E chipset supports 24 direct PCI Express 5.0 lanes from the processor, distributed as follows:
sixteen lanes dedicated to the video cards, allowing one GPU to run at x16 speed or two GPUs at x8 speed each.
Four lanes are dedicated to fast NVMe SSD storage, providing the highest storage speeds.
Four lanes are general-purpose GPP lanes, giving motherboard manufacturers the flexibility to use them as needed for additional devices.
