[WCCF]AMD Bulldozer (Zambezi-FX) Specifications Leaked by Asus - Page 21

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.
What's the point of comparing? You know SB is going to be faster than a Phenom even without benchmarks considering both Intel and AMD's architecture changes over the years. K10 chips in the same price range just don't perform as well as SB, so why compare the obvious?

Who cares? Pointless argument. BD will be out soon and the real comparisons can begin. This line of arguments is going nowhere and noone really cares. Let people compare them if they want, it isn't going to affect your or my decision on what to buy.

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.
If you have time to read the "Bulldozer blog is live" thread in the AMD section (all 100+ posts), you'll know more than you probably want to know about the architecture. This is a pretty decent overview, though, that shows the shared bits:

This entire thread is pointless, we're all just giving our opinions, everything has been said and said again. The only thing left to do is wait for actual numbers.

Well, its a rumors section. All we can do is give our opinions. Once there are facts, it won't be a rumor anymore....

So basically they share Cache(L2/L3), Fetch and Decode(again, way over-simplifying). Way less than I was aware of. Btw, isn't Sandy Bridge's FPU's 256 bit now? What was Nehalem's, 128? I apologize for the misinformation and all my previous posts in other threads about this as well. The AMD's are far more so a true 8 core than I had thought. Still not a 100% full 8 cores, but more so than most would like to think.

Thanks for explaining the rumor section, my point was this thread still contains no worthwhile information, just our personal opinions.

Well what i posted is based about the cores is based off AMD official slides.

But anyways, it don't matter if we compare Phenom II to SB now or Bulldozer to SB or whatever, because people will always complain about test's not being fair or being biased. Basically, when Bullozer benchmarks come out and it is compared to SB that is basically a pretty fair comparison. Regardless which is faster we all win. Why, because we call get new tech to play with.

I'll give you credit for that one , I'm sure some haven't seen it. The comment was more referring the majority of replies, there were a couple of diamonds in the rough like yours but overall this thread was just fanboys going back and forth.


I for one will be glad when BD is released so we can put all of this to rest, whether it passes or fails, too many BD threads going around with nothing but speculation.

According to the anantech article I linked you to, Core2, Nehalem, Phenom II and Athlon II all have a 128bit FPU. Sandy Bridge has a 256bit FPU but can't split it like BD can. Here's a blog post from JF-AMD that explains why AMD thinks their "Flex FP" approach is better:
