Thuban & Zosma info/code name from anandtech "Juicy"

Huh? the tdp is still 140W. The same thing that a 965 BE C0 does to a mobo, this guy will do as well. Come on, stop inventing problems. The tdp is the same as older AMD CPUs so i don't understand why it would be a problem now.

OFC, when OCed it's going to go up, but when you OC you usually cool stuff better than normal/stock cooling.

thats the point, OCing these things will get you 50 more watts of heat than any PII quad core will, except it will be possible to get those 50W without any extreme cooling. i could see someone using an average waterblock and pushing 1.55v into this for 4.2ghz and watching something burn.

[Hell Hound]

Sound's like the 9950 in a X6 package lol.

AMD should have focused on getting 32nm out of the door to allow high clock speeds and less TDP, because a CPU at 140W just isn't cutting it. I love AMD and I'm curious about these processors, but I don't like seeing a product using so much power.

AMD won't be spending any resource in pushing 32nm K10.5 parts
Let's look forward to BullDozer

Wow, common guys, the TDP has never scared me. I have yet to see a 965BE C2 140w chip run 140w load at stock or any of the AMD chips pull the rated watts. They are and have always been inflated numbers. I hope to see some results soon. I am eafer to get one.

Stand in line with the last of the Nvidia holdouts waiting on FERMI.

in that case then look forward to Fusion
K10.5 + GPU

It's a pity, though. 32nm parts could clock really high, and fill the void during 2010. Let's hope 6 core CPUs are going to be decent competitors!

Thuban is 32nm parts? I highly doubt that...

[informal]

Thuban is not 32nm and I doubt anyone claimed that,ever.

[initialised]

Your wrong, the good scaling in I7 CPU's is due to HT, without HT we would see lower scaling than on a PhII, like in a I5 750.

And also, you calculate scaling based on single thread performance, not on the ratio between increase in frequency over increase in performance.

That's data I took on a Gulftown, not an assumption.



What I was pointing out was that the linear 4x scaling on i7 quads does not extend to hexas, it appears to drop as core count goes up.

Depends completely on the application at hand.

AMD is a lot larger than 2 dudes in a garage banging out processors and working on fabrication. They have multiple CPU design teams, some working on Bulldozer while others working on K10.5 derived parts like Istanbul/Thuban. Global Foundaries is the company working on 32nm fabrication, AMD can't do anything until their 32nm node is functional.

those numbers dont give much room for growth do they. the 1075 has the same speed as a 945
also the TDP is listed alot lower than what we were already shown

I'm expecting at least a 3.0GHz with 140W TDP X6.







If you take a look at the charts you can see that the Shanghai(=Deneb) based Opterons current top modell is still a 3.1GHz with 140W TDP one while at desktop they already have a 3.4GHz with 125W modell with the same die. Yes I know it's already C3 but there is a C2 modell at 3.4GHz with 140W since May. The desktop parts are always ahead in frequency than server ones.

The current 2.8GHz(140W TDP) top Istanbul was released in last year's July. I can't beleive that they can't make at least a 3.0GHz modell for desktop.

[Hell Hound]

Not all boards support 140w so keeping it @ 125 means wider consumer base for that part.3.0ghz 125w makes more sense.

so you think that people who're buying 3-phase mobos will buy Hexa-Core CPUs that costs multiply times more!?

[Hell Hound]

Yes and the Gpu they buy will cost twice the price of the Cpu.The heat pipe's and eye candy on the board is not a necessity.

think, is some diference between "tdp" servers and TDP desktops in documents. But i dont know it at 100%

[Manicdan]

i think once we see what voltage they run the 2.8 at and at 140W, it will give us a good idea if they will make a 3.0 or 3.2ghz version. if they have a lower voltage than normal, we know there is little chance the 3.0+ can use the same voltage, and thus have a much higher wattage. but if the volts are normal, then they can probably just raise the clocks up and still very close to the same TDP. but i think most of us are praying it comes out at 125W

I'd expect 125W stock clocked Thubans(frequencies undisclosed). There may be a "top dog" BE/140W model,but new revision on which Thuban is based should provide solid headroom for both stock and OC frequencies .

Server "TDP" is ACP

TDP is TDP

Agreed


Otherwise I think that the AMD's wait about the desktop six-core Phenom CPUs launch is completely purposeful. Maybe they're waiting for the Intel to launch and advertise its rather expensive six-core unit and few weeks later AMD will say that, hey we have six-core CPU too for the Intel's 1/3 price.

[Manicdan]

^that requires AMD to advertise, which they dont do the best of job at.

[Behemot]

Server "TDP" is ACP

Good is AMD still specificates TDP (maximum power dissipation) next to the ACP (average power consumption). Intel's "TDP" is closer to what AMD's ACP is.

Sounds plausible. Also today I wrote something about Thuban in my blog:
http://citavia.blog.de/2010/02/05/so...the-t-7946531/

So I hope, Anton's story is not based on speculations published here and elsewhere.

BTW, he got his article about the BD architecture terribly wrong (similar to Fudo).
