is "8 core" BD really a quad core?

post #1 of 41
Thread Starter 
there's all the media talk of "OMG 8 core loses to intel 4 core!"

I think that's not really correct, should it be 4 modules vs 4 cores? But then again they look at the Bulldozer and are like "WOAH 8 cores!"

There 2 cores for ever module so yes.. it is a 8 core CPU.

BD is a real 8 core cpu, SB is a 4 core CPU with hyper-threading for a "theoretical" 8 core CPU. However the architecture for SB is superior, so SB quad+ht > BD octo

The key part that makes up a core is the actual processing unit inside the core, so since each module has two FPUs in it, that is 2 cores. So yes, 8 cores.

ah, i was confused, because the benchies shows the SB beating the Bulldozer quite badly... which makes me think, should they improve single-thread performance by running one thread per module?

define "core" please...we say things that have no real meanings, like we call most modern cpu's 64bit, but they aren't really, there plenty of parts that have more bits and less bits than that. they have 64 bit gprs, but 128-bit xmm registers, but the memory registers are 48 bit, and most fpu's are 128 bit...so why do we think of them only as 64 bit cpu's?

so to answer your questions, you'd have to answer what makes a core.

yea that's the problem, it used to be that a "core" means the Intel and older AMD models.

However, the bulldozer changes this quite a bit, so, a single definition of "core" doesn't apply to all chips.

CPU-Z shows 8 cores/8 threads, so I would assume it's 8 "real" cores?

Who cares, it doesn't work how it's suppose to, and that's all that really matters in the end, isn't it?
