Theoretical CPU question.

[via]

im not an expert at CPU's so humor me. would a 4 core i5 clocked at 4.0GHz be just as powerful as a 4 core i7 clocked at 4.0GHz? for specifics i am comparing the 4690k and the 4790k.

i7 has hyperthreading, i5 does not

 

if you are running something which can utilize hyperthreading, the i7 pulls ahead, if not they will perform pretty much the same, at the same frequency

are you talking about if you disabled hyperthreading would they be identical? yes

[CoolaxGaming]

No, I7's always have hyper threading,, which will make it win

But if there was a i5 and a non-hypered i7 at both were at 4core 4ghz, same architecture, they would perform the same

 

And for the 4790k and 4690k, the i7 is faster because it has hyperthreading

They would perform the same in gaming

They would perform the same in gaming

I dont think so.

I7 will always bout ~2fps faster

That's by margin of error.

 

They are the exact same without hyperthreading

Are you sure?

The i7 has a faster clock speed

[Comessy]

Are you sure?

The i7 has a faster clock speed

No he's asking about if they are both at 4.0ghz

[CoolaxGaming]

Oh ok... Sorry, I misunderstood your last post.

Eh, no. i5s anf i7s are different gens, and would never match up with each other. Hyperthreading, more stable OCing, the works. i7s tend to have better silicon lottery also.

They would definietly not be the same. The I7 has Hyper threading and uses more power/ Can Clock more and Keep more cool thus making the I7 at the same Clock speed superior
