Intel structure advantage is high performance of individual thread. You can see the good score in single core benchmark above.
i3-3220 is 2C4T and supports Hyper-Threading. IT will be 30% faster than own 2C2T CPU.
Former share, Ivy Bridge 3770K, single thread performance is 3~6% faster than Sandy Birdge 2700K and 10~14% in multi-tasking.
Comparing i3-3220 and i3-2120, the performance is close. It may causes by L3 Cache capacity.
