Thunderbolt and USB are changing? Robbie explains How and Why http://www.span.com/search/usb_space_type-c SuperSpeed USB 10Gbps (USB 3.1 Gen 2) from the USB-IF The SuperSpeed USB 10Gbps (USB 3.1 Gen 2) Specification adds a 10Gbps speed mode that uses a more efficient data encoding and will deliver more than twice the effective data through-put performance of existing SuperSpeed USB over enhanced, fully backward compatible USB connectors and cables. The specification extends the existing SuperSpeed mechanical, electrical, protocol and hub definition while maintaining compatibility with existing USB 3.0 software stacks and device class protocols as well as with existing 5Gbps hubs and devices and USB 2.0 products. Delivers 10Gbps USB data rate * 2x improvement over current SuperSpeed USB 5Gbps data rate Improved data encoding for more efficient data transfer leading to higher through-put and improved I/O power efficiency Compatible with existing USB 3.0 software stacks and device protocols Works with both existing 5Gbps USB 3.0 hubs and devices, as well as USB 2.0 products SuperSpeed USB (USB 3.1 Gen 1) from the USB-IF As technology innovation marches forward, new kinds of devices, media formats, and large inexpensive storage are converging. They require significantly more bus bandwidth to maintain the interactive experience users have come to expect. In addition, user applications demand a higher performance connection between the PC and these increasingly sophisticated peripherals. SuperSpeed USB addresses this need by adding an even higher transfer rate to match these new usages and devices. USB continues to be the answer to connectivity for PC, Consumer Electronics, and Mobile architectures. It is a fast, bidirectional, low-cost, dynamically attachable interface that is consistent with the requirements of the PC platforms of today and tomorrow. SuperSpeed USB brings significant performance enhancements to the ubiquitous USB standard, while remaining compatible with the billions of USB enabled devices currently deployed in the market. SuperSpeed USB will deliver 10x the data transfer rate of Hi-Speed USB, as well as improved power efficiency. SuperSpeed USB has a 5 Gbps signaling rate offering 10x performance increase over Hi-Speed USB. SuperSpeed USB is a Sync-N-Go technology that minimizes user wait-time. SuperSpeed USB will provide Optimized Power Efficiency. No device polling and lower active and idle power requirements. SuperSpeed USB is backwards compatible with USB 2.0. Devices interoperate with USB 2.0 platforms. Hosts support USB 2.0 legacy devices. For the Thunderbolt 3 news, read below: Major Thunderbolt™ Computer Update Major computer OEMs will have shipped Thunderbolt 100 million Computers with Thunderbolt by the end of 2015. 250+ Certified Thunderbolt peripheral devices such as Highest speed and capacity portable storage, Multi-card reader hubs without bottlenecks, 4K 60Hz docks and Display docks. Computer Ports over the years: 1998 – USB consolidates and simplifies data ports 2011 – Thunderbolt 10Gbps interface for data + display devices 2014 – USB-C connector - Small - Reversible - Fast - 100W charging - Alternate Modes 2015 – What’s Next? Namely, Thunderbolt™ 3, Codename Alpine Ridge. Thunderbolt™ 3 brings Thunderbolt to USB-C. Featuring: More Speed More Protocols -The USB-C that does it all. -More Pixels -More Power -Dual 4K displays -60Hz -100W -charging 15W devices -40 Gbps fastest connection -More protocols than any other I/O controller -Connect any dock, device or display, including billions of USB devices Alpine Ridge integrates a USB3.1 (10Gbps) host controller – among the industry’s first to market. More Speed! Thunderbolt™ 3 (Includes USB 3.1).Moving from HD to 4K creates substantially more data than the transition from SD to HD. Two 4K displays has nearly 16 million more pixels than one HD display. View and edit photos and video on a notebook while simultaneously connected to 4K 60Hz display and external storage from a single port 4K TV’s and displays for under $999.
