The names are Kevet, Keifer and Larrabee (possibly Larabee, Laraby or Larraby), and they all are, or were, mini-core projects at Intel. Larrabee is the survivor, it was just given the go-ahead while Kevet and Keifer were axed. RIP whatever they were.
This brings up the question of what mini-cores are, and what are they intended for. More interesting is why a sales-person in the PS3 section of the Roseville, MN Best Buy knew what they were? ยต
