PCPER.com: 5 GHZ+ Phenom II Overclock on Dry Ice, 6Ghz on LN2

oh, wonderful news

phenom 2 for me, lads :D

6ghz.... whee, didnt think ill be seeing that on an amd processor, ever... :eek:
yet breaking down the coldbug on that architecture

I've had AMD for a while now, and at this news, I'm even more sure of hanging onto it. ;)

Hope its true.

Getting AMD back in the game would be awesome.

Faster and cheaper hardware for everyone!

So many sources are confirming this message .... Yeeha! :D

If this is true, I am so ready to buy a AMD-system

You're saying these don't have coldbug and they will be cheaper than bloomies?

I say: I'm getting an phenom the second!

Lets just hope the retail ones can keep the same numbers. And hope these aint another cherry picked ones like the 3Ghz Phenom that was earlier.

Also as said the 6Ghz already changed. Plus here is abit more about the rest:

AMD took care of that itself at an event in Austin this morning, where it showcased four overclocked Phenom II systems. TR editor-in-chief Scott Wasson was on the scene, and while AMD didn't allow attendees to take pictures, he jotted down a few details.

The slowest system—cooled with a heatsink and fan—managed to reach just under 4GHz with a 1.55V core voltage. With liquid cooling, AMD successfully pushed a 45nm Phenom II in another machine just over the 4GHz mark. That required kicking up the CPU voltage to 1.6V, however. For the other two systems, AMD took out the big guns. One was strapped to a phase-change cooler and reached the mid-4GHz range at 1.7V, while the fastest system managed to well over 5GHz using liquid nitrogen (which kept the core temperature down to a chilly -185°C).

So no 4Ghz without water. And even with phase its mid 4Ghz at 1.7V. And the 5Ghz+ was 1.9V.

There he is!

Funny thing is, that's not what most sites are saying, at least thats not the consensus. So you start off talking about cherry picking, then go cherry pick a statement/news article....:nono:

Looking forward to it, if it's true. First AMD chip I am considering since S939 Opteron.

mostly NB speed will decide where the final performance ends against the intel parts.... its already shown on shanghai that cache latency and prefetch is way better, nb speed on deneb will be higher then shanghai.

:welcome: to an AMD news thread

perhaps first make a list of all kents and york's that hit 4ghz below 1,55vcore on air playing games (no not just cpu-z) before you make such a statement...

here he goes again :rolleyes:

those reports about shift in marketing are true, but real address for kudos is Dresden design center and AMD-IBM team in Fishkill ;)

Don't remember who posted this explanation about AMD's 65nm doldroms (maybe Hans)

http://www.eetimes.com/news/semi/sho...printable=true

But with 45nm tech things are complitely different, and AMD/IBM team has done some amazing job with their imersion 45nm tech, that yield all these goodies (lack of coldbug, high voltage tolerance, high clocks...)

You can read all about it here: http://www.eetimes.eu/semi/showArtic...printable=true

this part is most significant:

The new design of the PFET moves the embedded silicon-germanium source/drain regions closer to the channel to maximize the transfer of stress, thereby increasing hole mobility. Although shorter gate lengths are not driving the improvements, it is a reduction in dimensions that allows increased channel stress to provide the performance scaling. AMD 45-nm PFET design reduces the space from embedded silicon-germanium to the channel edge by half.

The transistor drive current for AMD's 45-nm devices is much lower than that of the Intel HKMG transistors. But power consumption is quickly becoming a high priority for server chips. AMD's transistors exhibit very low channel leakage.

Our transistor benchmarks indicates that leakage current is less than one-third of the value measured on AMD's 65-nm process. It's also significantly lower than the Intel 45-nm HKMG process. In fact the Ion/Ioff ratio for AMD's PFET is nearly 10 times better than that for the Intel PFET.


oh when I remember some comments on this forum that SOI is doomed with coldbug for eternety, and that is unable to produce any benefits beyond 90nm tech :rolleyes:

Its funny how 6Ghz reported by everyone is now 5Ghz+ by everyone :D

And not even 4Ghz on air?

I wonder what more will change.

And you seem to want a flamewar?

Remember AMDs 65nm was also better than Intels 65nm in this area....

Its more likely that they want to show enough to get the enthusiasts interested & not enough to get the attention of Intel that could lead Intel slashing prices heavily on its product range before AMD gets the P2 out the door.

It worked for ATI with NV prices being way off the mark because ATI held a little back of the 4XXX's full potential.

In fairness this isn't the final stepping. Could be even better come retail launch.

I am struggling to believe this statement without the IV curves and Ion/Ioff curves to assess the validity of this.... it just sounds way way to much.

here is what I mean, Intel's drive current for PMOS is about 1000 uA/um at an Ioff of 100 nA/um ... that is a ratio of 10:1, for AMD to be 10 times better would mean that at a Ion of 600ish that the EETimes article is quoting ... their Ioff would need to be 6 nA/um this is an order of manitude lower than any PMOS Ioff ever reported for a high performance high Vt proces. Ever.

It is just hard to believe.... hopefully AMD/IBM will produce some data at IEDM in a few weeks and we will be able to see if this guys claims are true... I sincerely doubt it.

At this time this is actually higher than what Nehalem can do.

while i'l be glad if amd is back in the game, i'l believe it when i see it. With so much hype lately and no actual delivery from amd anything is possible. Let's see retails do that.

Pfew, I was almost afraid you wouldnt show up anymore, but well, you prolly have the same reason as Ive anyway regarding timzone and stuff.

Anyway, how many Intel systems actually reach 4Ghz+ without water? There's a few nice chips from Intel but seriously, there ain't a lot different with those results compared to Intel:rolleyes:

But it's indeed recommendable not to have too cherry picked chips, more of pre-testing a bunch not to risk to have a lemon.

average 3.6 on air with 1.4v, more voltage doesnt help really...

some chips can do 4ghz on air (TRUE) with 1.4v but not that many...

Are you speaking from personal experience with these chips? Or are these your estimates?

I hope this is for real. I haven´t seen any cpu that turned me on after the Q6600. Maybe AMD will recandle my cpu upgrading flame. Well guys don´t forget what happened with the release of HD 48XX CARDS: (lowered prices and something new to play with) On a more serious note, ain´t you guys bored with overclocking only Intel chips.

AMD fanboy detected...:p:

Anyway, these are GREAT news for the consuming community. Competition = Lower Prices = Better technologies to come... etc :up:

the future looks nice :) hopefully most can do 3.6-4Ghz... will this be AMD's comeback ?... nice to have some competition again...2009 will be fun

Saaya works for Foxconn if I remember correctly, so I guess it's from experience.

I pretty much expected these chips to be cherry picked, but that does not mean we won't be seeing any of its overclock potential. Current 65 nm. Phenoms don't always have a coldbug either, so it's not something that came out of nowhere. My guess is that we will be seeing coldbugs on Phenom II, but not on all of them (hopefully not on most of them).

The AM3 versions of Deneb will probably be even better than these stepping C2 version and 4 GHz. on air should not be a rare sight to see with those is my guess. The C3 2,8 GHz. part has a DP of 95 compared to the 125 W. of the C2 version of the same clock, that has got to account for some improvement to the process and CPU. I'm eager to know what these chips will clock like in about a year from now, as AMD has the tendency to greatly improve its manufacturing process over time.

EDIT:

BTW guys, could we stop making nasty comments (or flame baiting/trolling) to others, even if you consider that other user to do so himself (once in a while). You should not say things about others and to others that you don't like to be said about you. Or how some would say it, don't lower yourself to someone else's standards. It will only put you in bad light, so speak.

Well he certainly seems to have connections. But it's not necessarily a given which is why I asked.

That makes me think of another question I'd be interested to know: Does foxconn have any plans for future enthusiast AM2+/AM3 boards?
