So I can suppose that is a RX 460 inside a RX 560 case... is this a fraud from Sapphire? The label ON the board says SKU# 11267-01 also

!!!

If I'd be you, I'd surely be pissed about it, as AMD clearly states what is considered RX560:

so there should be no cards like yours

Thank you for your help: I opened a ticket on support.sapphiretech.com
I let you know...
