Bulldozer Die Shot!

[Olivon]

Where is Hans de Vries?

Right Oliverda, we need Hans !!!

^^

I measured again and got 15% difference this time.

It can't be the other way around, the difference is too small for that.

Semi accurate does not open for me

Here is a roadmap for reference "First bulldozer based cpu "

Here is another site with same/similar news

The Orochi disappeared from the roadmaps on the last year's analyst day...

p.s.: Sadly, the core structures are blurred and no crucial detail could be seen.

WHo says it's a 4 module/8 core part? I'd say it's two modules/four cores (one on the left, one on the right).

[slaveondope]

So Orochi is 4 core if so Id take it each module is per a side(large upper and smaller lower linked = module)

distance between smaller core and shared resources into bigger core is very long

[Mats]

I'd say it's two modules/four cores (one on the left, one on the right).

I thought so too, but I can't see why they'd put one integer core that far away from the rest of the module.

[hurleybird]

No. You aren't going to have L3 (or L2 in your theory I suppose) sitting between the cores in a module, they would be more tightly linked than that. All the information we have already points to orochi being 4 modules anyway.

Does anyone else get the feeling that AMD is playing with us/Intel? I mean, showing such a provocative die shot with the important fine details blurred out kinda seems like they are intentionally trying to confuse the hell out us!

[ajaidev]

Amm am i not seeing 4 L2's "unconnected" is it not true that the cores of a module are suppose to share the L2 not to mention other elements? Why put one part on the module on the left and another on the right?

[Manicdan]

im getting the feeling this is just showing us what 2x K10 cores would look like with a little more L2 @32nm vs 2 BD modules with less L2

[hurleybird]

I think the 2 module theory can safely die now. Bobcat + bulldozer theory is interesting, but the modules seem to have too many similar/identical structures.

Perhaps we're actually looking at a six core part. The road-map that was posted earlier:



Shows Orochi not as an eight core part, but a >4 core part. My best guess here is that only the top two are actual "modules". The bottom 2 are single cores, with lots of cache, designed to get lots single threaded performance. Heterogeneous computing.

Hell, it's just as likely something else, but that's the only thing I can think of that makes sense right now. If true, it's hard to believe AMD would let something like that out of the bag.

[Raqia]

Could be that this is a Fusion part... but it would look strange for a Fusion part too.

[Hans de Vries]

Perspective corrected shot:



The upper two "modules" are definetly larger, but their respective L2 arrays are opposite of that.

JF already said that they would do some photoshopping to hide
the details. The lower modules look more as what I was expecting.

I'm becoming more convinced of my six-core theory. The only part about it that doesn't make sense is why AMD would show their hand like this.

The cores seem to be too big for single bobcat cores but single core bulldozer is a possible assumption with greater L2 cache and much better single/dual thread performance.

So in this theory we would have 2+2+1+1 cores = 6 cores

Yeah, the high resolution picture is obviously shopped to hide the details in the core. Are you saying that you think the different sized caches/modules are also shopped? That seems less likely to me, but if that's it I'm sure we could get JF-AMD to confirm it.

[informal]

This is the 8core/4module part and the image is heavily photoshoped (that's why the 2 module above look different/bigger).It's just AMD being cautious.

Yep, they've blurred out the core/module areas of the die. See the larger picture few posts above.

So can you guess what die size would be from that pic?

Also doesn't it look like top two modules cache seem a little compressed compared to the others?

[JF-AMD]

That is an 8-core Orochi.

And some blurring.

And some photoshopping.

Actual die shots are released at launch, not before. Don't start doing math on this, if you think the "single threaded client performance from a server benchmark" numbers were way off, anything done off of this die shot will be even more incorrect.

[hurleybird]

So, this isn't an actual die shot? just a mock up? the modules aren't different sized?

Forgive me, but it does seem a bit funny to create a fake die shot, blur out the 'sensitive' parts, and then present it to the world as the real thing at a GF event...

[Oliverda]

It's a fake by AMD.

I think that the yellow highlighted parts are the visible corners of the real cores. You can see smaller parts on the top because they put larger fake cores to there.
