There is no physical difference Between 215-08520xx project (” Hawaii “) and 215-08800xx (” Grenada “) ASICs.  The only difference Between the full variants (ie CUS 44 and 64 ROPs) with binning and fuse configuration. 215- 0852000 – Hawaii XT (67B0h DID MA-RID 0h, 0h MI-RID) 215-0852022 – Hawaii XT (L) (67B9h DID MA-RID 0h, 0h MI-RID) 215-0880004 – Grenada XT (DID 67B0h MA-RID 8h, MI-RID 0h)The XT (L) bin is the Highest Quality of Hawaii family of ASICs. The dies are binned for LOWEST Possible leakage characteristics in order to reduce the power consumption and dissipated heat. it is only Used in 295X2 cards. “Grenada XT” has the Highest leakage characteristics of Hawaii family. Higher leakage makes it Possible reach Higher clocks without violating the design of electrical characteristics of the die, in terms of voltage. The down sides in using high leakage ASICs are the Higher Temperatures through the board and Higher power consumption (due Temperatures and lower VRM efficiency). Any performance difference Between “Hawaii” and “Grenada” cards is Caused by the display driver. AMD changed the configuration fused in a way the driver can tell the difference Between “the old” Hawaii and “the new” Grenada cards. They both obviously share the DeviceID but “Grenada” Their cards have revision number bumped to 8 hours (instead of 0h on Hawaii). The revision number is Configured by the fuse configuration During manufacturing and can not be Altered by the bios on retail cards. If you are testing differences Between “Hawaii” and “Grenada” bioses, note That “Grenada” bioses have Higher clocks thru the different performance states Than “Hawaii” bioses. This Means That if at some point the card Reaches it’s power limit and starts to shuffle through the different performance states, the “Grenada” cards Might Appear to Be Faster Than “Hawaii” simply Because of the Higher clocks. If you are testing the differences Between the two bioses, make sure you have the power limit set to the maximum setting (+ 50%) on both of Them. Ps. Internally “Grenada” has been Called as “Hawaii Refresh
