Template:Infobox Component

The Jasper is the successor to the Falcon, and is used in the Original Xbox 360 series.

Notable Differences

  • The 80nm Rhea GPU has been replaced with the 65nm Zeus GPU
  • The XSB has been replaced with the PSB
  • Arcade Jaspers came with 256MB (later 512MB) nand chips that combine system storage and a Memory Unit
  • Traces and pads for an additional flash controller (referred to as "DUMBO" or "PANDA") have been added, but never populated
  • Other small changes were made to the board layout
  • 8x64MB Hynix H5RS5223CFR RAM was added, only used on a small number of boards
  • Very late Jaspers manufactured in July 2009 come with the Kronos GPU instead of the Zeus GPU
