USB data transfer is about to get a lot faster. The USB Promoter Group is rolling out SuperSpeed USB, a supplement to USB 3.0 due out later this year that should surge your speeds two-fold.
SuperSpeed USB is supposed to give you 10 Gbps USB data rate, which is the same theoretically as Thunderbolt but in actuality this is only burst speeds and not sustainable like Thunderbolt and of course is not two way or capable of driving monitors are like Thunderbolt is It's also expected to feature better data encoding for transfers, more efficiency power efficient ports, and best of all, compatibility with existing devices. Later this year when you download a movie or a CD, it could take much less time thanks to the new standard.
To take advantage of the double-speed USB 3.0 interface, devices such as computers, hubs, and digital cameras will need new USB controller hardware. However, the new version of USB 3.0 uses the same connectors, so existing USB devices can be plugged into the higher-speed ports.
USB 3.0 cables may or may not work. "Existing SuperSpeed USB cables are not certified to operate at 10 Gbps; it is possible that some existing SuperSpeed USB cables may be capable of operating at 10 Gbps," the group said.

The New Tegra 4 CPU for Smartphones Is here and it's fast. It packs 72 GPU cores, 4 A15 CPU cores, and a built-in LTE.
In a (somewhat simulated) head to head test between a Nexus 10 tablet and and a Tegra 4 mystery machine, the latter loaded 25 webpages in only 27 seconds, with the older chip taking 50. Not many of us will be loading up 25 webpages simultaneously, but Nvidia is hammering beefed up browser performance here—as well as topping the iPad 4's A6X processor across the board. Nvidia says it's simply the fastest mobile processor in the world. Nvidia says.
The Tegra 4 will also have supercharged HDR photo rendering, Nvidia says, beating out the iPhone 5's abilities with better capture speeds thanks to all of those aforementioned cores working at once. In actual life terms, Nvidia says it'll be the difference between two seconds of rendering on the iPhone and 0.2 seconds on a Tegra 4-powered mobile camera.
One particularly nifty feature is "live HDR," which actually shows a video preview of the difference between a shot with and without HDR. Very impressive, and nothing we've ever seen before.
Nvidia is banking pretty heavily on the virtue of HDR here! Sometimes it looks nice, sometimes it looks tacky—but at least with a live preview you'll be able to tell beforehand.
A demo of Dead Trigger 2 running on Tegra 4 yielded some highly purty visuals—think early-PS3 era—though there was some slowdown. Still! This is phone and tablet tech. Fancy stuff.
No word on when we'll start seeing these things in our things. Soon!
