USB4

A week after USB 3.2 Gen 2.2, we get USB4. Intel had previously announced that its Ice Lake platform, due to ship later this year, will integrate both Thunderbolt 3 and USB 3.1 Gen 2 (aka USB 3.2 Gen 2) controllers. Currently, offering Thunderbolt 3 requires the use of an additional chip, one of Intel’s Alpine Ridge or Titan Ridge Thunderbolt 3 controllers. Intel said that it would contribute the Thunderbolt specification to the USB Promoter Group, the same organization that announced the USB4 specification. Doing so will enable other chip makers in the USB-PG to build Thunderbolt 3 silicon royalty-free. As such, we’d expect to see it become nearly universal. Why is this such a big deal? Thunderbolt 3 on the 3.1 standard could bring 40Gbps data transfers, which is about double the speed of the preceding USB 3.2 specification. Its exciting times ahead as, universal standard with higher power delivery has endless possibilities.
