AMD demos 45nm at Cebit.

[informal]

Let's just stop the Nehalem talk and concentrate on 45nm K10.
From the Cebit today came the information that Shanghai will consume 15% less power than 65nm Barcelona parts.So this is very good news.Also this is not a straight shrink of the core since the 3x larger L3 cache and some core changes.This thing will definitely be better per clock and per./watt(even more so) than Barcelona\Phenom.AMD just needs to hard launch this baby in Q3/Q4.

Hard launch and 3g+ launch (stock) speeds please... pretty please

I wouldn't mind a high-clocking tri-core. It's basically a dual-core with an extra core for alt-tabbing out of a dual-threaded optimized game. I'm looking for an e8400 equivalent from these new AMD 45nms...if they can pull something like that off (same price range), I'll return to the home land haha.

[Marvin_The_Martian]

This thread isn't about tri cores but native quads

[w0mbat]

clk should be <2GHz w/ this model

[Sparky]

Wondering if it would be a worthwhile upgrade from my current 9600BE I just got... depends on price, performance, and how much of an OC I can get out of my current chip (way too busy to OC right now - 36 hours work + 13 hours school + homework + eating + sleeping = no time to OC )

[grunge100]

Things are starting to look better for AMD

Any word on the Puma platform yet?

That's just early silicon right? Anyone have some insight already at which speeds these will launch?

I wouldn't call C0 early silicon

AMD 45nm Deneb C0-stepping K10.5 live @ cebit

can't wait to get my hands on AM3 haven't messed around with an AMD rig for too long.

[Marvin_The_Martian]

but <2ghz can't be a real clock speed unless this was their slowest lowest offering and that wouldn't quite fit the 'showcasing tech' standpoint right? I'm just hoping 45nm will bring Amd closer to the oc potential off them other chips from Redmond.

Since the A and B series were Barcelona/Phenom, it's actually as early as it gets.

[informal]

The purpose of the showing was not the clocks but to show that the design works well in the present form and can run software error free today.The clocks should be higher than Agena FX that will come in late Q2(2.7/2.8GHz).So i expect them to launch a new FX chip at the 2.8GHz in Q3 or if it slips maybe in Q4,with 2.6Ghz in Q3 then.These chips will have lower TDP/power requirements than 65nm Phenoms and will probably OC much better(since they have same current limitation for the socket AM2+,both for cores and IMC and this means that they can run with lower voltages for the same clocks as Agenas)

sry

I'm afraid I'm not very familiar with AMDs procs

[BrowncoatGR]

It also looks like B3 beeing the last revision of K10 might be true

Well if you take in to account AMD's history of manufacturing transitions. You'll notice pattern from which one can conclude that first revision of the new manufacturing process is focused on bigger yields rather than higher frequency bins.

K8 first revision – Clawhammer – 130nm was all about getting as much as possible dies out from the factory! Getting from initial 2 GHz to 2.2 GHz was harder that today for K10 to get from 2.2 to 2.4 GHz!

K8 second revision – NewCastle – 130nm allowed reaching 2.4+ GHz, and those advances was implemented in Clawhammer (1MB L2 version) later on, so those chips also reached 2.4+ GHz…

Transition from NewCastle and 130nm to Winchester and 90nm resulted in smaller chips and bigger output from 200mm wafers, but equal clocking capability to proven and mastered 130nm tech. With arrival of 90nm Venice core, things started to change in fawor of 90nm tech!

With Windsor AMD squeezed maximum from 90nm tech, but between Winchester and Windsor there were Venice, San Diego, Manchester, Toledo, Orleans! So it's no wonder that with arrival of the first 65nm core – Brisbane it's predecessor Windsor was more overclockable! But, AMD needed just one revision of 65nm tech to surpass excellent previous tech. I'm talking about G2 Brisbane

I do believe that B3 revision of Agena will bring little speed up, and we'll finally get faster CPUs in compassion to Phenom 9600! Also I believe that Deneb's main purpose is to bring bigger K10 output thanks to smaller chips, and that speed gains in terms of clocks will not be spectacular. It's just common business sense.

But second revision of 45nm, the one that'll bring Ultra-Low-K tech will bring significant clock improvements, just as AMD stated in their FAQ about 45nm tech.

[Marvin_The_Martian]

Yeah they need those faster gates I remember now having heated arguments about this with someone stating Amd could reach the same clocks as Intel using their current process.

Think I wasn't paying to much attention to all the details atm.

But using older generations to predict the future is something which can bite you in the behind, it's not like tech developments follow historical rules.

[Piotrsama]

Best AMD news in a long time.
Looks very nice.

[zakelwe]

20% improvement is good news over 65nm K10, is this IPC or due to increased speed? If it is IPC then what is the major change that has given them this boost?

10-20% IPC improvement due to far bigger L3 cache and several tweaks to the core.

[dinos22]

this is unexpected

hopefully we'll get to see them fulfill the promise this time round even though half yearly estimates are large enough

so December this year maybe :d hehe

macci please do something about those damn cold bugs

<edited> meh, that guy was clueless (reference to something completely different, and way out of left field, ignore this) -- AMD has focused on 45 nm now for sometime, my general gut instinct is they got 65 nm to an acceptable (not perfected) point then put all resources... so it may indeed turn out well.

[MotF Bane]

Evidently Shanghai and Deneb are already shipping:

http://www.informationweek.com/news/...ubSection=News

Now we just have to wait a little bit, and then samples will almost certainly show up here.

[da-key]

Voltage at 1.64 is a bit interesting. How much headroom can it have already that high?

Ahhh, I edit the link out... that guy obviously confused AMD's sampling of B3 65 nm with 45 nm Shanghai demo.

Voltage reading is not correct..

I think he maybe was implying that AMD shipped the ES 45nm parts to major partners for validation and testing purposes.

See here:

Advanced Micro Devices on Tuesday said samples of its first 45-nanometer processors have been shipped to computer manufacturers, and the company is on track to start production in the second half of the year.
