Need Info MT6589

Hello guys, I just bought this phone: http://www.fastcardtech.com/HDC-Galaxy-Note-2-H7189

And I saw here that this phone comes with PowerVR SGX544 GPU, and when I googled some other sites, I found on a few places in a product description that the phone has PowerVR SGX531 GPU..

Now my question is; is it possible that phones with Mediatek MT6589 processors come with PowerVR SGX531 GPU?
Or does this mean that these guys on other sites just got a bad info??

Regards,
Emrah.

P.S.
I saw on wikipedia right next to mt6589 processor that it supports PowerVR SGX544.. Link: http://en.wikipedia.org/wiki/MediaTek
But I am still not sure if the phone has to come with SGX544, or if that is the maximum that CPU supports..
