Notable Differences

  • The 80nm Rhea GPU has been replaced with the 65nm Zeus GPU
  • Hynix H5RS5223CFR and Hynix H5RS1H23MFR RAM were added as options
  • 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
  • Very late Jaspers manufactured in July 2009 come with the Kronos GPU instead of the Zeus GPU

The Jasper Tonasket (also known as Kronos) is the successor to the Jasper, and is the final motherboard used in the Original Xbox 360 series. Despite having a different name, it is still considered a "Jasper" by Microsoft.

Notable Differences

  • The 65nm Zeus GPU has been replaced with the 65nm Kronos GPU, which shrinks the eDRAM to 65nm
  • Samsung K4J10324QD-HC14 RAM was added as an option
  • Hynix H5RS5223CFR is no longer used
  • 8x64MB RAM configurations are no longer used, but still supported by the motherboard
  • The 256MB nand chip was no longer used, only 512MB configurations were used in Arcade
  • The additional traces and pads for DUMBO/PANDA flash controller were removed
  • An alternate simplified standby circuit for V_3P3STBY and V_1P8STBY was added, but only some manufacturers used it
  • The board layout was cleaned up
  • All motherboards use an updated RF02 board
  • The extended GPU heatsink was reverted back to the low profile GPU heatsink
  • All boards now use solid state capacitors for the CPU and GPU output filters
  • There is no longer glue applied around the CPU and GPU
