not full cores, 8 integer cores.

It matters because if they were two complete cores with the architectural advancement made since Phenom, they may have been the same speed on a core for core basis as Intels offerings, who knows? (in before Intel fanboy says no way, couldn't happen! LOL)

But the point is AMD didn't want to build yet another cpu based on the same old core concept and decided to build Bulldozer the way it is, with its shared components and cut down cores.

You're deliberately missing the point entirely. It's a piece of silicon, how it's divided up at a microscopic level it completely irrelevent, Intel fanboys should know better than anyone else that it's benchmarks that count.

If AMD wanted to put 500 cores on a cpu the same price as an Intel 4 core, so what?

I'm not missing the point what-so-ever. The post was more or less directed at the people thinking it was some form of HT on the Bulldozer; which it isn't.

The people that call others fanboys are usually fanboys themselves.

No. Wrong, completely.

It has two integer pipelines and one floating point pipeline, the integer pipelines appear as cores to the OS...Intel's hardware just makes the OS think there's two integer AND floating point pipelines instead of one, hence, all the hardware is shared, AMD has more separate parts in each pipeline (EG. Separate pipelines, L1 cache), its still mostly shared though so it ends up being the same thing with more efficiency basically...Hence, 4 modules is the same as 4 cores on Intel with HT, but a 4 module CPU wouldn't be compared to a 4 core CPU without HT. (Just like you couldn't expect an i5 750 to beat a i7 860 at the same clock speed in an app that uses more than 4 cores)

If I were to guess, I would say that BD is 50% faster than Phenom 2 and 20% faster than the i7-950 which puts it on par with the 2600K like I've said all along.
They're talking about the x6 which is practically equal with an i7 950 in multithreaded scenarios, so I'd assume that's where Bulldozer shines.

Pipelines ≠ Real Cores, by your logic, floating point pipelines don't help define a core...

To put it bluntly, Hyperthreading is like having a 386 with a 387 copro that appear as though its two 386s and two 387s, BD is like having two 386s but one faster 387 for both, as well as shared RAM.

It is AMDs form of HT, I don't see an entirely separate core in BD, I see two half cores with shared components...It's just a way of fitting more cores on die, just like HT is, albeit less efficient.

Wrong in what exactly? It has two independent integer schedulers (albeit shared FPU) with two independent threads... that's essentially two cores and two threads as I said.

I'd only ever call it a form of HT in extreme laymans terms.

It has shared L2 cache (iirc), a shared FPU and nearly everything else is shared.

All HT does is put two processes down the one pipeline to save die space rather than have full extra cores, this simply has two pipelines sharing other parts of the CPU to save die space rather than having full extra cores...Same purpose, just because AMDs modules are a hellova lot more efficient than HT doesn't mean they're not the same idea. (i.e. Not a full core, but adds similar extra performance)

An 8 core CPU has 50% performance on a 4 core 2 year old CPU?
Wow, that's aghhh, really something. Lets hope that this report is to be false and there is a greater distance in performance in the two CPUs...

as for the argument alot of you are having, who cares what brand has the more powerful product, at then end of the day people are looking for performance for the price.. unless you do have the money

Look above, it's also a quad core.

I'm sure BD will be a big improvement over the Phenom II. Not sure if it will be faster than an i7-2600k though. We'll have to wait to find out how good it really is.

One thing is for sure.
If it blows it sucks.

EDIT: I have a 1090t and AMD share so...
as above mentioned.
