Lots of misunderstanding in this comments section.
Movidius makes low power neural network processors for mobile application. The Myriad V1 is used in google tango and the V2 (what the USB stick has) is used in the new DJI Phantom 4.

The Myriad chips are interesting because they combine MIPI camera interface lanes on the same chip as a general purpose NN/CV processor and an SDK suite of hardware accelerated computer vision functions (edge detection, Guassian blur, etc).
here's the white paper for the chip: http://uploads.movidius.com/1441734401-Myriad-2-product-brie...
Because programming these chips essentially requires having the hardware, and because the hardware was very hard to come by, programming these chips was mostly limited to Google, DJI, and other big partners.
With this release the everyday developer has access to these vision processing chips, and the barrier to development entry is considerably lower.
This is not meant to replace your titan X gpu.
