Intel prepares two new Thunderbolts in 2013

Written by Fuad Abazovic

Redwood Ridge 2C and 4C

Intel currently has three Thunderbolt controllers selling for its 2012 platforms. The one that needs the least power is called Port Ridge 2210 and it’s a device only port, supports 10Gbps but no display and it is a 0.7W TDP device.

Cactus Ridge 4C 3510 is a host and device controller with 4 Thunderbolt channels supported. It works as a PCIe Gen 2 (4 x1 or 1 x4) unit and supports Display Port 1.1a with sink and one source. It has a TDP or 2.8W and supports one or two connectors.

The last on the list is Cactus Ridge 2C 3310 host only with two thunderbolt channels 10 Gbps bandwidth, Display Port 1.1a with one sink. It has 2.1 W TDP and supports a single connector.

The new devices coming in 2013 are codenamed Redwood Ridge 2C or 4C. Redwood Ridge 4C 4510 is a host and device, supports four Thunderbolt channels 10Gbps Display Port v 1.1a with 2 sink and 1 source as well as new Display Port v 1.2 redriver. It is PCIe Gen 2 x1, x2 or x4 capable, has TDP or 3.1W and with Intel power optimizer in battery its idle power drops to below 1mW compared to 7mW in 2012 generation units.

The new Redwood Ridge 4C 4510 supports one or two connectors and fits the 12x12 mm FC-CSP with integrated SVR package. The runner up is Redwood Ridge 2C 4410, a host only device with two thunderbolt channels, 10Gbps and Display port 1.1a 2 sink or Display Port v1.2 redriver support. Display port v 1.2 brings a support for higher resolution, doubles the bandwidth to 17.28 Gbit/s as well as multiple independent monitor streams via daisy chain.

It needs 2.3W with one display or 2.45W with two display and still operates at t same less than 1mW idle power. It supports 1 connector and you will find them in Shark Bay notebooks, Haswell powered in 2013.

We would not be surprised to see Apple as one of the first customers including these new ports and Display Port 1.2 support on its latest MacBook Pro notebooks.
