The USB Promoter Group, a consortium of companies including Apple, HP, Intel, Microsoft, and others, announced the “pending release of the USB4 Version 2.0 specification.” The update won’t be finalized sometime before November, so don’t expect to see PCs and other devices with USB4 Version 2.0 before the end of the year.

Data speeds are the main improvement this time around, just like with most USB updates. The maximum speed is now 80 Gbps, thanks to a “new physical layer architecture,” which is expected to be compatible with 40 Gbps existing cables. That’s faster than Thunderbolt, which maxes out at 40 Gbps across both Thunderbolt 3 (which USB4 is based on) and Thunderbolt 4. That could lead to improved external GPUs and other hardware that requires an ultra-fast data connection.

The new standard, at least on paper, may provide a speed boost with older hardware as well. Devices using USB 3.2 can only…
