Not sure if you read the article:
In addition, NVIDIA also introduced a brand new type ofhigh bandwidth SLI bridge*that it has dubbed*SLI HB. This bridge facilitates high-speed data transfers between SLI interfaces by linking both connectors in*a dual-link SLI mode*that offers more than double the bandwidth of older bridges. More specifically, the new SLI interface runs at*650MHz, as compared to 400MHz in older GeForce graphics cards using the legacy bridges. This allows the SLI HB bridges to take advantage of Pascal’s higher speed /IO, and enables users to better maximize performance at 4K resolutions or higher.
In fact, NVIDIA says that certain older SLI bridges – custom bridges with LED lighting to be specific – will also be able to operate at 650MHz when used with the GeForce GTX 1080.

The NVIDIA GeForce GTX 1080 is the undisputed single-GPU king, that much is clear now. But what about two of them in SLI? We plugged a couple of these cards into our test rig to find out!
