The ASM4242 is said to have a PCIe 4.0 x4 interface and does as such support up to 64 Gbps of bandwidth. As this is a two port controller, it's still not quite enough to enable both ports to operate at the full 40 Gbps that USB4 Gen 3x2 supports, but it should be enough for most consumer implementations. ASMedia has also added support for DP Alt Mode and USB4 is of course also backwards compatible with Thunderbolt 3. ASMedia is already sampling its partners. We should hopefully get a better look at what ASMedia is working on next week, but DigiTimes mentions that ASMedia has also developed PCIe 5.0 controllers of some kind and have finished the tape-out of said products.

ASMedia to Launch USB4 Host-Controllers This Year
Taiwanese ASMedia appears to become the first peripheral chipset company to launch a USB4 host-controller chipset, based on reports from an event the company held this week. ASMedia is at least the first company to get certified by the USB-IF, as its ASM4242 host-controller is the first of its kind to get certified. The ASM4242 was certified alongside the ASM2464PD device controller, although it's unclear exactly what type of device controller this is, but the PD in the model name indicates that it has native support for USB PD power delivery, without the need of any additional chips. This should allow for simpler implementation, as well as it would be saving some PCB space that the extra components no longer take up.The ASM4242 is said to have a PCIe 4.0 x4 interface and does as such support up to 64 Gbps of bandwidth.
