The motherboards for AMD processors with Thunderbolt 3 connector were officially certified by Intel for the first time. The certificate was given to ASRock - X570 Phantom Gaming ITX/TB3 motherboard, which is a small form factor Mini-ITX motherboard based on the latest AMD chipset for X570 enthusiasts.
Intel has previously not charged any license fees for Thunderbolt. Instead, vendors were not allowed to manufacture a silicon Thunderbolt controller, and now this is allowed freely. A lump-sum payment is now required and is not disclosed. It is unclear whether Thunderbolt certification will continue to exist after USB 4 standardization in the market.
Thunderbolt 3 as a USB Type-C port offers up to 40Gbps faster speed, which is twice the bandwidth of USB 3.2 and four times faster than USB 3.1 connectivity. It also offers serial connectivity for up to six devices.
