Cheaper memory on the card... XFX uses Elpidia memory generally.
This is very surprising to Me!
What else can affect the same card model kh/s 
Also is t h e r e any way to find out if the shop sells the same brand but with elpidia memory?

Depends on the brand, the XFX wont do more than 1300mhs. I'm able to pull 1530mhs with the stock fans in an AC'ed room and using bathroom fan to suck the warm air away from the cards on an open rig, temps don't go over 72C with 20C ambient temperature, I have Asus 7990's, hope it helps.
this helps thanks very much.I thought no one will reply and I forgot about this question.
Why do XFX go lower? The brands can only change cooling design right? Everything else stays as OEM (AMD) made it.
