Thread: Why is Core i7 920 better than Phenom 2 955

I just want to ask the question about Core i7 clock speed is lesser, the amount of cache is the similar but why does it performs superior in most apps? I wonder how, I doubt why?

Core I7 architecture is special to Phenom II structural design. The frequency (clock speed) is not the most significant factor any longer. Some differences:

I7 has more L3 Cache, HT technology (which allows it to become an "" 8-Cores-CPU """ ). A better memory controller system (Tri-Channel and up to 2000Mhz vs. Dual-Channel and up to 1600Mhz... right?).

By the way, there’s not a giant difference. It depends on the software you make use of; on High-Resolution gaming they run very comparable. But I7 is superior in many other things.

I think it is mostly due to Intel's superior cache and prefect design, as well as, given the core2 cores have superior IPC than K8's then all things now equal both now have an IMC then the i7 is somewhat faster on most applications than K10.5. i7 as well as K10.5 both have cores that are basically based on their predecessors.

In my view the Phenom II is still superior value for money and quick enough for most. The Average user isn't going to actually see a difference. Oh yeah Hyperthreading is an attention-grabber, it still only has four processor cores.

You can't judge against Hyperthreading from the P4 era at present. If it made no distinction, why does both performance as well as power consumption boost when it is enabled?
