Why did Amd go with "Modules" instead of more "Cores"?

post #1 of 12
Thread Starter 
Has it been discussed why Amd went in the direction that they did? Why did they think this route was better then a phenom iii X8?

This is not a flame thread. Im just curious as to why they did what they did.

To save on die space.
Which is kind of ironic, since the die is much larger than SB and doesn't perform as well.

amd probably screwed up somewhere or there really is some extra performance hidden somewhere in the bd design...


but a design isnt good for only 1 year ... its rehashed and improved over time ... and that is how we should look at it


how far can bulldozer be scaled and improved ???

Sorry if I sound stupid and uneducated but what do you mean by modules instead of cores? I thought the latest line of FX processors were true 8 cores? (This is just from looking at the new banner for the FX cpus on Newegg CPU sections. )

That's one of the modules.

Each module has two cores. However, since there is one L2 cache in each module, it is being shared by both cores.

I wish I could understand how much of this works (FMAC, schedulers, pipelines)

They wanted to go to modules so they can fail epically that is why...They are committing masochist behavior

This is a whole new design. I'll admit, I fell for the marketing. We all did. We thought this was going to be a great chip. Apparently not.

Like the smarter people on this forum have been saying, this is a new architecture and since AMD is a much smaller company compared to intel, so you can expect a slower "maturing" of the architecture if you're used to intel's marketing and pace of development.

Maturing means optimizing or working out the kinks, if you will; In theory, the architecture looks great but now that it's out and in our hands, they are learning more about how it works in real world application and can improve on it. Although benchmarks can serve as a viable means of assessing a processor's power, it is how the processor performs on stage that matters. However, the benchmarks do show some serious potential. Will AMD ever be competition to intel? I doubt it. AMD's glory days are over. As a company, Intel has now grown to gigantic proportions while AMD, in retrospect, can now be considered a baby company. But hopefully, like I said before, they can pull a rabbit out of their ass.

I'm still vexed about the marketing though.

Scalability i would imagine. Of course the design was supposed to give more performance per watt and be efficient also but it isn't. There is definitely something wrong with BD and they need to fix it.

You really couldnt find this anywhere else?
Read the anand review in the BD benchmark thread. It goes into a lot of detail on the design behind BD. Short answer is to be able to fit 8 cores, taking out the least components or those that require a lot of space. Instead of 2 integer cores and 2 FPUs, they mashed the FPUs together to create one FPU that could be used by either "core" or all of it applied towards a single core (128 bit per, or 256 bit for one). Again, read the review for more details.

because the old architecture was dieing, atleast the new architecture does decent against intels offerings.
