Intel on Monday announced an upgraded version of its Thunderbolt tech, with 20Gbps throughput instead of the current 10Gbps. With that, the new technology, which is expected to arrive in 2014, will support 4K resolutions, possibly pointing to even higher resolution Mac displays. Most notably, perhaps Apple will finally unveil an iMac with Retina display next year.

As of now, Apple is limited because of the current Thunderbolt technology. With a bump up that doubles Thunderbolt's capabilities, Apple will have the means to introduce more eye-popping machines. In addition to the upgrade in Thunderbolt technology, codenamed Falcon Ridge, Intel will also unleash next-generation core processors in 2014.
