hashing power question

[dadach]

can anyone answer why would the same model vga cards, purchased 6 months later give out 20% less hashing power. ok, the 1st batch was unusually high, but the same version of the cards bought afterwards is slower. any insight? memory speed? circutry? thanks

For every VGA chards, the settings is a little bit different.. Try adjusting it and you should get the same hash rate....

Patches, better optimized for graphics leading to less optimization for other unintended uses.

Every GPU also have diffrent ASIC score, some you can overclock more and some you can't so you can't have the same settings for alll...

Yes, check the bios version and ASIC score by using GPU-Z...
