The USB Promotors Group has just officially announced the arrival of the USB4 specification, which will supersede the newly formed (and highly confusing) USB 3.2 protocol. USB4 promises to double the transfer speeds of USB 3.2 thanks in part to a critical move made by Intel. Intel has made its Thunderbolt 3 protocol royalty-free, which will allow competing chipmakers to offer implement the standard at lower costs. It also means that USB4 is based on the underlying Thunderbolt 3 protocol. As a result, maximum speeds for USB4 double to 40 Gbps using existing certified cables, matching the speeds offered by Thunderbolt 3. “By collaborating with the USB Promoter Group, we’re opening the...

Were you just getting used to USB 3.1? Well, we’re sorry; the USB 3.2 specification has just been announced, which means that we’re in for yet another speed bump for the interface that we all have come to rely on to connect our peripherals USB 3.2 in essence adds an extra lane to the existing USB 3.1 spec. While USB host controllers were initially designed for single-lane operation, the USB 3.2 spec doubles that to two, allowing for two 5 Gbps lanes (which would equal the 10Gbps maximum of the current spec) or two 10 Gbps lanes, boosting maximum throughput to 20 Gbps. Thanks to this extra headroom, the USB 3.0 Promoter Group says that consumers will soon be able to achieve 2 GB/sec transfers... Read more...
