Well if you have an infinite GPU maybe,keep in mind that console cores are jaguar cores that run at less then 1.5Ghz ,probably a lot less when all of them are working,consoles are completely dependant on splitting tasks up into multiple threads since all 6 of their available cores are probably slower than a single i3 core without the HT.
We already have most AAA titles filling up the console cores completely,there is no difference in how they get used the total amount of work stays the same and the i3 has shown that it is fine running such workloads.
