To USB or Not to USB


Why we need Double-Speed USB 3.0, Thunderbolt goes to 20 Gbps

As reported by the Apple Insider, the Innovator announced double-speed ThunderBolt under the code name Falcon Ridge this Monday.

This means ThunderBolt 2.0 will run at 20 Gbps.

You can seen the graph below at Apple Insider (originally published by the Innovator) This clearly gives Thunderbolt a lead over USB 3.0, and is 2x the speed of 10G USB.

Comparison of USB 3.0 and Thunderbolt 1 and 2

Published on Apple Insider who got it from the Innovator.  You know who they are.

Because it’s 1:40am here, I’m not going to explain all the usage scenarios except to say that Thunderbolt at 20Gbps can carry 4k video UNCOMPRESSED which needs something like 18.9 Gb/s and lots of data as well.  This might even eliminate the need for an HDMI chip and a royalty to the HDMI people.

More another day, but now that Thunderbolt 2 is 4x the speed of USB 3.0, it makes sense that next gen 10G USB running Double-Speed USB 3.0 will be absolutely needed as a second, open interface for those who don’t want to use the closed, Thunderbolt 1 or 2 standard.  Thunderbolt 2 will start shipping in 2014.

Look into the Thunderbolt pricing for chips here and a video explaining how and who makes money here and why the standard stays closed.

More importantly, it makes USB 3.0 imperative, absolutely necessary to implement now.
