Lets look at the whole picture not just one test.
In the cinebench, pcmark, 3DMark test group: SP3 won 4, SP2 won 5, with 2 Ties.
most differences were less than 10% with 1 each between 10 & 15% difference (11 & 13%).
In the browser test & other 3D mark group: SP3 won 7, SP2 won Zero, No Ties.
3 test were won by 10% or more, 4 less than 10%.
Then you have DOTA and WIFI. sp2 wins DOTA by 40% and SP3 wins WIFI by 39%.
SP3 handily won all the browser tests, and the WIFI test and was pretty even on the rest with only one exception. You know what. I don't even have to think about this. I'll take the SP3 every time.
