Pentium G3258 - How can it be slower than an i3 @ -1GHz

view story

http://forums.anandtech.com – Can someone please explain how can it be that in benchmarks (admittedly not all) the Pentium chip running 1 GHz faster than an i3 4330 be slower? And in the cases where it's faster, it's not by much. Is that extra megabyte of L3 cache that important? Can hyperthreading really make up for a 1GHz difference in clock in multi-threaded tasks? Or is the Pentium chip crippled in other ways than those two? (OK, there's the lack of AVX, but how many of those applications used in benchmarks really use AVX?) (Hardware)
