Yesterday, the USB Promoter Group revealed the next evolution of its ubiquitous peripheral spec: USB4. The new specification, which is still a draft in the final stages of review, is based on Intel's Thunderbolt 3 protocol, delivering up to 40Gbps throughput over existing, Thunderbolt spec-certified Type-C cables. That's twice as fast as current USB 3.2 maximums. It's also backward compatible with existing USB 3.2, 2.0, and Thunderbolt 3 specs and devices. Read More
USB 3.1 still isn't incredibly common on consumer electronics, but the USB Implementers Forum is looking to the future. The group has formally announced the new USB 3.2 standard, which not only promises to be twice as fast as USB 3.1 (in some cases), but will also be far more confusing. Read More
The USB Promoter Group has just announced the USB 3.2 spec update with one major change over USB 3.1: multi-lane operation on hosts and devices and thus double the bandwidth on existing SuperSpeed Type-C cables.
With USB 3.1, both hosts and devices were designed for single-lane use. The SuperSpeed cables, however, were designed with multi-lane in mind, but weren't able to make use of it because the devices they connected to on both ends didn't support it. Thanks to USB 3.2, upcoming certified hosts and devices will support multi-lane operation so existing cables can benefit from double the speed when connected to them. Read More
