The USB Promoter Group has announced the pending release of the USB4 specification, a major update of USB architecture that builds on the existing USB 3.2 and USB 2.0. It doubles the bandwidth of USB and enables multiple simultaneous data and display protocols. The USB4 architecture is based on the Thunderbolt protocol specification recently contributed by Intel.
The new USB4 architecture defines a method to share a single high-speed link with multiple end device types dynamically. This ensures that the connections best serve the transfer of data by type and application. As the USB Type-C connector has evolved into the role as the external display port of many host products, the USB4 specification provides the host
“The primary goal of USB is to deliver the best user experience combining data, display and power delivery over a user-friendly and robust cable and connector solution,” said Brad Saunders, USB Promoter Group Chairman. “The USB4 solution specifically tailors bus operation to further enhance this experience by optimizing the blend of data and display over a single connection and enabling the further doubling of performance.”
Key characteristics of the USB4 solution include:
- Two-lane operation using existing USB Type-C cables and up to 40 Gbps operation over 40 Gbps-certified cables
- Multiple data and display protocols to efficiently share the total available bandwidth over the bus
- Backward compatibility with USB 3.2, USB 2.0 and Thunderbolt 3
With over 50 companies actively participating in the final stages of review of the draft specification, the USB4 specification is on track to be published around the middle of 2019. Coincident with the release of the USB4 specification, the release of an updated USB Type-C Specification will be made to comprehend USB4 bus discovery, configuration and performance requirements.
USB Developer Days 2019, in the second half of this year, will include detailed technical training covering the USB4 specification and the latest for USB Type-C, USB Power Delivery, and other exciting topics.
This update is part of the USB performance roadmap and is specifically targeted to developers at this time. Branding and marketing guidelines will be established after the final specification is published.
“Releasing the Thunderbolt protocol specification is a significant milestone for making today’s simplest and most versatile port available to everyone,” said Jason Ziller, general manager of Client Connectivity at Intel. “By collaborating with the USB Promoter Group, we’re opening the doors for innovation across a wide range of devices and increasing compatibility to deliver better experiences to consumers.”
“USB4’s high throughput and advanced features enable new scenarios in consumer, enterprise, and intelligent edge markets, while maintaining interoperability with existing USB and Thunderbolt 3 devices,” said Roanne Sones, Corporate Vice President, Microsoft OS Platforms. “We are excited to work with our partners in the ecosystem to bring USB4 to market and showcase its benefits.”
Google announces its ‘Netflix for gaming’
The new gaming platform, Stadia, promises high-definition gaming on TVs, computers, and mobile devices, writes BRYAN TURNER.
Google has announced that it has moved into the gaming space, and it focuses on two big aspects of gaming: streaming of games for gamers, which will allow gamers to game anywhere with a fast, low-latency Internet connection; and audiences that watch gamers in-game.
This is a big move in making gaming accessible to more gamers, as it reduces hardware costs, by utilising the benefits of low-latency cloud computing. This will be achieved by using a globally connected network of Google data centres. Gamers who stream games are most likely already using a high-speed, low-latency Internet connection, so access to the Stadia platform will be an added expense.
Through the Stadia platform, gamers will be able to access a large library of games at all times, with no installation time, on virtually any screen. Scaling of hardware like CPU, GPU, memory, and storage is also possible, as one would for cloud server resources.
Google will be leveraging its other platforms, like YouTube, with Stadia streaming. It claims that 200-million people are watching game-related content daily on YouTube. This allows, for example, Stadia players to jump in with other Stadia players – no downloads, no updates, no patches, and no installs.
For console players, Google has designed a custom controller.
The controller was designed to establish a direct connection from the Stadia controller to Google’s data centre through Wi-Fi for the best possible gaming performance. The controller also includes a button for instant capture, saving, and sharing gameplay in 4K resolution. It sports a Google Assistant button and built-in microphone, as many Google products do, for voice control.
The device is expected to be released later this year, pending FCC approval.
Nintendo announces Stranger Things 3 game

It is claimed to have modern gameplay mechanics to deliver nostalgic fun with a fresh new twist. Players will be able to experience their favourite show through a mix of exploration, puzzles, and combat.
Just ad in the show, teamwork is at the heart of Stranger Things 3: The Game. Players can team up in a two-player local co-operative, or in single player mode alongside an AI partner. Players can choose to play as one of twelve characters from the show, each with different abilities and attributes. Together, they’ll play through familiar events from the series, while also uncovering never-before-seen Stranger Things secrets, ensuring a fun experience for those new to the world of Stranger Things as well as for those familiar with the series.
