[Q]xperia z ultra lower benchmark? topic

Hey I have recently flashed the gpe 4.4.2 for xperia z ultra and I have benchmarked and found my phone is under what it is meant to be (i was using antutu) it Is sitting under the s4 and is meant to be above all but the note 3. I am at factory clock and I have 1.2g of ram free and I don't understand why it is not..well as powerful as it should be.
No background processes were running at the time. It got a score of 24712 and its meant to have something in the 3000 mark
