Everything on the AMD X870 motherboards
Screwless ports and WiFi 7 support
The AMD X870 and X870E support Ryzen 7000, 8000, and 9000 series CPUs. That way, you can choose which processor you use in the motherboard. A noticeable upgrade of these motherboards are the screwless M.2 and heatsink slots. This allows you to easily place an M.2 or heatsink in the motherboard without screws. The new generation AMD motherboards also have WiFi 7 support. This fast connection has a maximum speed of up to 46Gbps. This way, you can enjoy extremely fast wireless internet.
AMD X780(E): more PCIe 5.0 support
The AMD X870 and X870E motherboards have at least 2 PCIe slots. The secondary slots of the X870E also support PCIe 5.0. Using PCIe 5.0 is becoming more and more important, because it allows you to connect new and faster video cards to the motherboard. The X870E motherboards also have more variation in the number of lanes the PCIe slots have. For example, the ASUS ROG Crosshair X870E Hero gets 8 lanes and the ASUS TUF Gaming X870-Plus WiFi gets 4 lanes. This support is more extensive than with older motherboards. This allows you to place more expansion cards in the motherboard.
The largest difference between AMD X870 and X870E
The largest difference between the AMD X870 and X870E motherboards, is that the X870E has dual chipset chips. This allows you to connect twice as many USB and PCIe slots in the chipset. This means the X870E has a higher bandwidth. The X870E has 44 PCIe lanes and the X870 has 36 PCIe lanes. This makes the X870E more suitable for a hardcore games, because you can install more video cards. The X870E also has 8 SATA slots, just like the X670. This way, you can connect multiple hard drives to the motherboard. As a result, the X870E processes more data per second than the X870. That's useful for gaming, because you play with higher frame rates and with slowing down less.
USB4 ports for fast data transfer
A USB4 port has the same shape as a USB-C port, but a maximum transfer speed of 40GB/s. This is twice as fast as the transfer speed of USB 3.2. This allows you to transfer larger files such as 4K videos very fast. Just as with a Thunderbolt 3, you can connect your gaming accessories to the motherboard with a USB4 connection. You can also connect a 4K or 8K monitor with a USB4 port, via the DisplayPort Alt Mode.
