Alpine Ridge Thunderbolt slide claims 40Gb/s performance

Intel's next-generation Thunderbolt chipset, Alpine Ridge, has been apparently leaked in a slide claiming half the power draw and 40Gb/s of peak throughput.

A leaked slide purporting to offer a glimpse of Intel's upcoming Alpine Ridge Thunderbolt controller promises a significant speed boost over current-generation implementations, offering 40Gb/s throughput for connected devices.

Developed in partnership with Apple and featured as standard on the company's computers, Intel's Thunderbolt technology aims to offer a single cable type for all peripheral devices. In addition to high-bandwidth data connections, Thunderbolt offers PCI Express lanes and DisplayPort connectivity as well as carrying power to recharge portable devices.

The current Falcon Ridge Thunderbolt chipset offers 20Gb/s of throughput, double the 10Gb/s of first-generation parts and twice that of USB 3.0. A slide published to Chinese technology site VR-Zone claims that Alpine Ridge will result in another doubling of throughput, offering 40Gb/s of throughput and support for the PCI Express Generation 3 standard.

As well as doubling the peak throughput, the Alpine Ridge controller is claimed to run at half the power of its predecessor. The new chipset will also come with a new connector standard, reducing its height by 3mm to ensure compatibility with future ultra-thin portable devices. The new connector will support power transfer of up to 100W for rapid charging, the slide claims, while adapters will be available for backwards compatibility with existing Thunderbolt devices. Two Alpine Ridge SKUs are claimed for launch: a 4C version, which offers two ports and support for daisy-chaining of client devices; and the LP version, which offers just a single port and no daisy-chaining support.

Intel, as is usual for the company, has not commented on the slide to confirm or deny its authenticity, nor is it willing to discuss unannounced products.

If they want to make TB the new standard they need to reduce the price for the chips and cables. People are not willing to pay this big of a premium and simply stay with USB 3.

Unless they own an Apple device :)

Even then it's too high of a premium over USB3-devices. Look at the external HDDs for example. Yes the higher speed sounds interesting, but it costs allmost double the price of the USB3-version. And there's alot of people using MacBooks, who are not fanboys willing to pay whatever it costs.

Nice, a new chip that Apple can use to refresh its lineup and for everyone else to ignore.
