Why isnt a AMD 8350 better than a i76700k?

[RangerLunis]

This is probably a dumb question and been asked quite a bit before, but why would a AMD not be better than a i76700k? I'm asking this out of complete curiosity.

 

If you look at the specs, a AMD 8350 has the same clock speed as a i76700k but a 8 whole cores compared to the i7's 4. 

 

So why does the AMD 8350 not perform as well as the I7?

 

I actually personally own a i76700k and am quite happy with it, but i'm still generally curious, could this have something to do with how much cache each processor has or just something in build quality?

14nm vs 32nm. The 8350 is simply older tech. It's the same reason the 2600K is not as good as the 6700K

[Enderman]

because cores and clock speed =/= how much performance

IPC. 

 

 

[Sakkura]

Each Intel core simply gets more work done per clock cycle. A lot more.

[ivan134]

GHz is not an accurate way of comparing different architectures.

[tbake0155]

It's not about quality really, it's about micro architecture.

 

The skylake x86 micro architecture is more efficient and has newer more powerful instruction set capabilities (translates to new micro architecture implementations).

 

The i7 is capable of far more instructions per clock cycle.  CPU speed can only help but so much in this regard.  Think of it like gearing in a transmission.  A car with more horsepower can use shorter gears (less GHz) to get the same work done as a car with less horsepower but taller gearing (more GHz).

 

That's probably confusing too though : )

The clock speed only tells you how many cycles it can do in a second, not how much it can do work in each cycle.

Cause an 8350 is about as fast as Conroe.

not really no.

 

even the 32nm Sandy Bridge processors beat the 8350 at the same clockspeed (8350 @4.5ghz gets 725cb and 2700k @4.5ghz gets 800) 

It all comes down to ipc

[Djole123]

#1) It has a different architecture

#2) It has waaaaaaaaaaaaaay lower IPC

Same architecture (x86), different micro-architecture

Thanks for everybodies reply, I feel I understand quite a bit better. Pretty interesting stuff.

AMDs processors right now are on a 32nm process node right now while Intel is on 16nm. The smaller the process node the more transistors you can generally stuff into the same or similar size package. Every generation of processors has a certain ipc (instructions per clock) that each processor can perform. Intels are able to perform many more then AMDs right now. Cores and clock speed don't mean everything.

That explains great man, Thanks

Not to be mean but are you mental? you are comparing a cpu from late 2012 to a cpu from Q3 2015. How did you think it was going to be?

I know their both better man, but why are they better? The 8350 has 8 cores compared to the i7, i just dont know what exactly makes it better and i'm really curious, it's information I really wanna know, and I guess now I do. Of course I know a i76700k could wipe out the 8350

[DXMember]

because i7 costs more

The intel CPU's are better in single core performance and well newer.

intel is on 14nm

IPC has nothing to do with process node - it's not about who has more transistors, it's about how you use them

That answer does not help one bit you need to say the full thing "instructions per clock" also more programs are now using 8-threads which make the FX do great but not better than the overpriced i7-6700K...

Well I said not to be mean. I guess I am just a bit to tired of seeing all of this fx 8350 things and how it is so "bad". I am sorry if I hurt him in anyway

Nothin hurt mang, sall gud. I understand those questions are pretty annoying but I really just wanted the knowledge, the 8350 is fine for lower end builds and intel for higher end. I came here understanding how each one compares to the other but not the science or information or whatever behind why.

It's not a fair comparison. If you compare the 8350 to the 2600K you will be making a more sensible argument/question.
