Why are AMD processors faster and more efficient than Intel processors?

Despite adjectives the so called bench discoloration tests and culture that say Intel dual core is the best surrounded by the real world and independent carrying out tests there pretty much equal beside one exception Intel always costs more.The one check a lot of culture always guess wrong is gaming,AMD beat Intel hands down,At every turn, AMD give a hiding it to the punch. Even the Athlon 64 X2 3800+, the lowest end of AMD's dual-core CPUs, is better suited to 3D gaming than Intel's highest-end Extreme Edition 840 CPU, which lost by a full 10 percent. In multi tasking AMD also out perform Intel !I really get a hoot out of people wise saying how great Intel is without really knowing the facts.One entity Intel does is out advertise AMD so by race not in the know believe everything Intel say and buy Intel.
They aren't anymore...
Amd are the same efficency they are a different brand close to Mc Donalds and Burger King.

I think Intel make faster chips. Usually AMD is alway playing catch up. May be AMD are better at making it work better beside available memories.
