It supports the PCIe x4 interface and provides data transfer rates of up to 20 Gb / s, which is twice as high as the previous generation. It is noted that such a card will provide support for USB 3.2 Gen 2×2 specifications without the need to purchase a new motherboard. The USB Type-C ports themselves are backward compatible with USB 2.0 / 3.0 / 3.1. The USB 3.2 Gen 2×2 specification was first introduced in 2017, but only recently got to commercial devices. The first batch of hundreds of units has already been sold out, new deliveries are on the way. Many companies are trying to unify hardware solutions to use the same types of connections for different tasks. Today, USB 3.2 Gen 2×2 and Thunderbolt 3, which use a single connector, are considered the leading and fastest. As expected, in the future unification will allow you to “drive” data in different formats on the same cable, which will reduce the number of connections and simplify their replacement.
