Heat reduction: 560mA (emerald) -> 500-510mA (sapphire).
Stability: We stressed it with 9 Block Erupter USBs in a row without heatsinks heating up each other in a very dense USB hub with 25C without active airflow. No unexpected (non-probabilistic) HW errors ever happen.
Speed: This comes after better stability. Now the hashrate converges to its theoretical value of 336MH/s.
Appearance:
Manual assembly (emerald) -> SMT machine assembly (sapphire)
Standard heat-sink (emerald) -> heat-sink front-case 2-in-1 logo-ed (sapphire).
LED added.
