AMD Dodeca-core

[DeathReborn]

i REALLY REALLY REAAALLLYYY wanna know WHY amd abandoned dual chip in one package research back in the k8 days. WHYYYY????

Perhaps the culprit is the IMC, considering how in K10 they split it into two 64bit controllers.

[The Warlock]

I think it sounds promising with Shanghai , wonder how this will do on wcg crunching?

[triple_A]

Now let me see them 45nm 4ghz AMD's

[saaya]

agreed. we could've had quad core setups on old 939 back before c2d was even out.

i hear ya!

[YukonTrooper]

I think it sounds promising with Shanghai

Isn't that what we all said with Phenom?

[triple_A]

Isn't that what we all said with Phenom?

ehr.. no?

[YukonTrooper]

ehr.. no?

Yes it was. Everyone was stoked about Phenom ...until the reviews came out. AMD talked it up like a giant slayer and we all bought into it, because we all wanted to believe in it.

I just hope they deliver this time around. Less of this optimistic bla, bla, bla.

[cegras]

Not really. What I read about phenom in the press didn't quite make it sound as good as this, I think this time they're finally addressing issues that their marketing section wouldn't let them do. I'm more 'stoked up' about this announcement vs other AMD news releases : P

[twilyth]

I think it will have an effect on the server market. The chip is supposed to be 1207 compatible with the only difference being you don't get HT3 for interchip communication. So if you've got 4P boards with Opterons for 16 cores per board, and you can go to 48 cores just by dropping in new chips, who isn't going love that? You triple the output of your server farm with 1 simple upgrade.

If the Shanghai chips clock better than barcelonas, and i'm willing to bet they do, it's going to be a no brainer for any shop that already has an investment in 1207 servers.

1 simple upgrade? Well, I'd guess more like 4 simple upgrades. You can't just replace one processor. I'm guessing that Shanghai will improve a lot on Barcelona--it may not increase the MHz by much, but it should increase efficiency by a good bit. Many companies would rather a dense rack of slower machines in a small form factor--something that cannot be done very well with current Barcelonas. If they can match or beat Intel on performance-per-watt, they will have a sizable chunk, even if they don't have #1 performance.

i dont think thats the problem... there are memory bandwidth limited apps, and there are cpu power limited apps. the latter is more often, and in those cases 4 cores work greeat even IF you are limited by the memory bandwidth.

now think of this, intel can keep 4 cores happy, bandwidth wise, with the ancient fsb feeding them! so how could amd not maintain the bandwidth requirements for 4 cores with an imc? thats nonsense...
an x2 is even fine with single channel memory! thats all the bw it needs...

QFT!

[mAJORD]

agreed. we could've had quad core setups on old 939 back before c2d was even out.

hah you wish. The TDP on 90nm at that point in time was way too ty for that... (unlike now where.. space and perf concerns aside, a 2.6Ghz 90nm K8 could be MCMd and be within an acceptable TDP)

You won't see octocore shanghai until 45nm K10 is mature enough to allow sub 65watt TDP/core..

[Syn.]

Here is me just wanting a Phenom that is clocked higher then my 939 X2 4800+.

Today 2 cores is a high tech as software has got maybe by the time we start getting more then 6 cores we should see all software being optimized for them.

Until then i want faster performing cores, not just more of them.

[awdrifter]

Well, quad cores would be targets at enthusiasts, and the 90nm 4600 EE's TDP is only 65w, so they could've made a quad core with two of those and it's only 130w TDP.

I agree with mAJORD on this one. What we're seeing at 90nm today wasn't the case back during the 939 days. Both AMD and Intel have always improved their processes.

actually I believe the limit has less to do with hardware but more to do with bad programmers trying to get away with lots and lots of bad design decisions.

Heck right now I am using a Commodore 64, with a fully GUI and thus far the 8bit proc and 64kB of Ram have yet to limit my web browsing....

I see you..joke...as always.

More like a CLI based one with virtually nothing but simple text.

That's exactly what I want, I realize the ghz race was getting no where, but still, I'd rather be seeing some ultra fast dual cores with SMT than a native octo core as I'm 99.99% sure I won't be needing that power any time soon. I wonder what the effect of Itanium having the high core count and desktop cpus having the highest possible clocks and ipc would be on intel's profits

Same here, that's why my Wolfdale 8400 should be in my rig by next weekend. Having multiple computers mean I don't have multitask enough to worry about Multi-Core until at least the 2nd revision of Nehalem.

[Donnie27]

BTW, some of us never saw Barcelona/Phenom as a Conroe killer=P

[STEvil]

lets see here...
1 socket: 12 cores.
2 sockets: 24 cores
4 sockets: 48 cores
8 sockets: 96 cores.

Whoa...
