they actualy do dude, just go and look at an fx4100 review and compare it to a phenom II 980BE, you are looking an an fx8150 which clocks up to 4.2 and has 8 cores thats why it does better than a typical quad core phenom II, but comparing a quad core bulldozer to a quad core phenom II it fails miserably
only in situations were new instructions sets are supported does bulldozer hold ground,p but in typical use its way behind clock-clock, and yes by 20% if not more
phenom II does 3ipc while bulldozer does 4ipc shared between 2 cores, and because it has such a long pipeline each cycle takes a longer time(which isnt bad because its kinda designed that way so the resources can feed the second core in the module while the first one is munching on data)but things didnt go so well and the latency is worse than expected
heres some of conclusion from legitreview, i wasnt talking out of my ass just so you know
"When it comes to performance we were shocked to see the AMD A8-3850 'Llano' processor and the Socket FM1 platform performing better than the AMD FX-4100 'Bulldozer' processor and the Socket AM3+ platform. We quickly found out that the FX-4100 was priced this low as it needed to be. The performance of the FX-4100 wasn't awful, but we didn't expect to see the AMD A6-3650 running at 2.6GHz to beat the AMD FX-4100 running at 3.6GHz in benchmarks like POV-Ray and Cinebench! "
