USB 3.2 Gen 2×2: 2 GB per second from an external source in action

ASMedia has shown that the fast USB 3.2 Gen 2×2 works with a controller harness for the Computex 2019, or 2 GB per second for transfer performance. The controller is almost ready to use, but it will be hard to find by the end of the year.

Biostar shows on the stand how the signals change. The ASMedia ASM3242 chip is connected to four channels and makes it a fast USB 3.2 Gen 2×2 compliant port – this could also happen exactly on a motherboard in the future. In the external data carrier, one needs a chip that transforms the signals, in the case of the ASM2364, which frees the tracks again and thus allows the connection of a PCIe x4 SSD in the drive. location M.2.

ASMedia has its own small booth in the USB Implemeters group area and shows it in an additional live demonstration based on the Intel Coffee Lake platform. The Intel chipsets offer enough PCIe 3.0 tracks, so these extra chips can be soldered directly to the motherboards, AMD pulls right here with the new platform.

But the alternative will be at the beginning of a kind of expansion card, because it is already presented at the fair as a blank canvas. Packaged in a small attractive case equipped with an M.2 slot, it would be the clbadic addition of any of the motherboard manufacturers to high end cards. There is currently an M.2 expander for the PCIe slot as a purely internal solution. MSI has already hinted at this.

Background of the USB 3.2

To achieve higher performance than the USB 3.1 (USB 3.2 Gen 2), the USB 3.2 Gen 2×2 incorporates two data cables. Due to the multi-line operation, the raw data rate of 5 Gbit / s (USB 3.2 Gen 1) is expected to reach 10 Gbit / s, instead of 10 Gbit / s for USB 3.2 Gen 2 it is possible to reach 20 Gbit / s with USB 3.2 Gen 2×2. The prerequisite is a USB C type cable, for 20 Gbit / s, it must be certified "SuperSpeed ​​USB 10 Gbps".
