Notable Differences
- 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 Southbridge has been replaced with the PSB Southbridge
- 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 boards use solid state capacitors for the CPU and GPU output filters
- Some of the boards no longer have glue applied around the CPU and GPU
