Light Peak vs. USB:
Light Peak:
10 Gb/s simultaneous in each direction (100 Gb/s future)
Cable length 100 m
Can run video, audio and data at the same time on the same cable, in multiple protocols.
USB3:
4.8 Gb/s
Cable length 3m
Runs only data on the USB protocol
IMNSHO, USB3 is just evolutionary, taking the same thing we’ve been doing and going faster with it. Light Peak gives one thin cable than can saturate a hard drive’s platters and run multiple 1080p HDTV streams at the same time over the same cable. At least that’s if Intel can deliver.
And if the DRM doesn't induce a bunch of latency.
