Nope. There are going to be 8 physical integer cores according to AMD. They don't lie about the number of cores their CPUs have...

Also, it does seem fair to me to compare say a 2600k and a 8-core FX CPU. They both show up as 8-core when both actually only have 4. Intel uses hyperthreading to make it look like 8 and amd uses "bulldozer" modules contaning 2 interger cores to make a 4 core show up as 8. So IMO its even comparision.
I'm hoping the same L3 cache means locked cores in the lower model(s). Would be very nice if the 6 cores are 8 cores with 2 disabled like Deneb. Also, neither is 8 true full cores like you stated, but AMD is much more 8 true cores than Intel's. The OS counts the number of cores based on the number of Integer cores present. Intel's has 4 Integer cores with software somewhat emulating the other 4(I know it isn't exactly this, just trying to simplify). AMD's has 8 full hardware Integer cores. The only difference is the lack of the FPU per Integer core in AMD's vs. Intel. So pretty much AMD has 8 Integer/4FPU and Intel has 4+4 Integer/4+4 FPU, where the +4's are HT "emulated" so to speak.

Hard to compare the two now, as they are using unconventional methods and neither are using what we would call a typical and standard core. I do agree the should be compared directly to each other though, as they will be in the same price bracket and both are 8 thread CPU's.

Funny, that's not what you implied at all...

We were comparing 965 performance to 2500K then you came in and it changed to K10 chips in general. My comment still stands that it's illogical to compare SB with K10, they were never meant to compete. Sure, the prices on high end K10 chips might be close to SB, but performance is considerably lower because of the architecture; BD was developed to fill this gap and compete with SB, whether or not it will we'll see soon.

Actually you started the general comparison, with the very first line of your reply to his post.

What's the point of comparing an architecture as old as K10 with Intel's newest?
Architectures are general, not processor specific. To say that they aren't competing in the current market is incredibly ignorant. So until BD is released for comparison it is completetly valid to compare processors currently being sold by either company. So have fun justifying to yourself why they can't be compared but the simple fact is, that is the only comparison we can make at this point in time.

You're completely missing the point and putting words in my mouth. I never said AMD isn't competing in the market in general, I said the K10 architecture is so old it can't compete with SB, a brand new architecture which it was never intended to compare with. The prices are close for now but this will presumably change after BD.

The simple fact that K10 is what is being sold by AMD at this current time, regardless of its age or ability to compete with newer architecture, makes comparisons valid. Sure it wasn't designed to "compare" with SB, it was developed long before. But there is simply nothing else to compare SB to. Comparing SB with BD is about as good as comparing it to a magical unicorn, we simply don't know anything about its performance yet.

I'll be glad when the professional reviews are out and these misconceptions can be, hopefully, put to bed permanently. BD has one 128bit FPU per integer core, so the FX 8xxx processors will have "8 integer/8FPU". The two 128bit FPUs can be combined into a single 256bit FPU and dedicated to a single core in a module when needed.

First I had heard of that. So if this is true, what did AMD "take out" of the total module package that would have been included if it was two complete normal cores instead? They have stated many times that it shares resources and components between the two Integer cores, so what exactly is shared? They have said they are getting 80-90% of the performance of two complete, non-shared resource cores by sharing, so what do they share exactly? I was under the assumption it was the FPU and some other more minor things. Not arguing with you, I am genuinely curious.
