Notable Differences

A July 2009 Jasper with a Kronos GPU
  • The 80nm Rhea GPU has been replaced with the 65nm Zeus GPU
  • Hynix H5RS5223CFR-14C and Hynix H5RS1H23MFR-14C 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
  • Some of the boards no longer have glue applied around the CPU and GPU

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-14C RAM 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 the Arcade SKU
  • 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
