Hello,Would you please tell me why is the Intel Core i5 760( 2.80GHz - 1MB L2 - 8MB L3) faster and has better results than the AMD Phenom II X4 965 BE ( 3.4GHz - 2MB L2 - 6MB L3) , though the x4 is 600MHz faster than the i5? http://www.anandtech.com/bench/Product/102?vs=191
Thank you

Simple answer: the 600Mhz you mention is not accurate.

The i5-760 has Turbo and often runs at 3.5Ghz in many of the tests you linked. Thus in reality the Intel is often running 100Mhz faster than the AMD and not 600Mhz slower like many people would really like you to think.

(And when not running at the max turbo of 3.5Ghz it is still often running at a boosted state which means it could be running at something like 3.2Ghz or 3.3.Ghz. RARELY would it ever be running at the base clock of 2.8Ghz if the machine is not in an extreme environment.)

The max turbo is 3.33Ghz, not 3.5Ghz, and whilst it is true that the machine would rarely be running at its base clock of 2.8Ghz, it is also equally true that the i5 760 simply has higher IPC than the PhII 965.

The quick lookup of the max I did obviously was wrong. (I looked it up again... it does say 3.46Ghz as the max for that chip.... so I guess that website was wrong.)

But the IPC difference is not great as many people have been erroneously led to believe.

And it is also still true that the difference is not the misperceived 600Mhz the OP quoted.

i5 760 = $209
PhII955 = $149

Choose thy poison, and thanks for stopping. Bye.
