AMD Phenom II hits 5GHz stable

A sneak peek given to the press by AMD, showcased their upcoming line of processors known as the "Phenom II".

The Phenom II are AMD's answer to Intel's newest chipset, the Core i7. Hoping to compete in the market with the Core i7 the Phenom II line of quad-core processors will be AM2+ compatible. The first two models to be released will have a clock speed that starts at 2.8GHz. However, one of the key bragging areas for AMD's line of Phenom processors is its overclockability.

AMD claims a 30-40% reduction in power consumption under full load thanks to their transition to a 45nm fab process. AMD has also stated that in addition to the 30-40% power consumption reduction that consumers can expect, they should also expect a 30-40% increase in performance over previous Phenom models.

In a demonstration, AMD displayed the overclocking power of the Phenom II X4, showing it hit 4GHz stable at 1.55v on air cooling with a temperature of 32?C. With water-cooling the CPU broke the 4GHz barrier with a 39?C temperature. For kicks and giggles the Phenom II was shown running stable at speeds higher than 5GHz on nitrogen cooling and even booted at speeds that were higher than 6GHz.

It's too early to say whether or not the Phenom II's can match the power of the i7's as we'll have to wait until benchmarks are released to do so, but the competition seems anything but idle.

This is a blessing for us AMD fans. Glad to see AMD has turned things around

I wouldn't get your hopes too soon. I really want AMD to bring there "A" game to the next round of processors, but until we see numbers, we should reserve judgment.
#1.2 generic mike on 21 Nov 2008 - 20:41
True true, need to see the benchmarks, but AMD is really the only competition for Intel right now and if AMD goes under than Intel will have, in the simplest description, a monopoly.

If that happens then Intel will have a possibility of raising prices, lowering standards of progress or both.

One thing is hitting 5GHz the other is calculation power...

4GHz stable at 1.55v on air cooling with a temperature of 32?C.

OMG! i hope thir performance are alike!
Edit:
At thir stock speeds.

AMD haz megahurtz?! impossible!

How events turn around eh? few years ago when Intel posted records of overclocked northwoods and prescotts, AMD kept reminding us that clocks do not fix inferior architecture (which is true)

Now it is the opposite after years trying to erase the concept of clocks speeds to describe cpu speed.

overclocking is about upping the speed on a processor. overclocking has nothing to do with the 'inferior architecture.' therefore, this is simply a demonstration that their processors are not only more efficient than the previous generation, but that they are also far more overclockable. don't get your ideals twisted into thinking they're going back on what the said about clock speed, they were simply showing the flexibility of their new chip.
#4.2 carl0ski on 24 Nov 2008 - 02:41
It's also a promise that official Phenom processors will soon after be available at higher clockrate of the to be released 2.8ghz. Upto 4.0GHZ is on the possibility list of being release shortly after launch.

Unlike the original Phenom which barely exceeded its launch speeds of 2.4ghz? and hurt it's potential for future growth in consumers minds.

Yes, it's all about instructions per cycle, and other factors.

That's not necessarily true. MHz does not count for nothing. Imagine a 0 mhz processor, what use would that be to you?

I don't really.

Same Architecture means the IFC wouldn't have changed
MHZ must count for something otherwise all Intel i7, Core2duo and Core2Quad models would have the exact same price tag as their family.

I believe that a 30-40% increase over previous phenoms is still less than the i7 can do.

I think you're right. If it's close enough, it can help drive down the cost of both Intel's and AMD's chips.
#7 lylesback2 on 21 Nov 2008 - 18:52
I was waiting for AMD to return fire on Intel when they released i7.

I love competitions like this!
#8 KillerZ123 on 21 Nov 2008 - 18:56
I hope AMD is back. I want to see some performance numbers first but even if the i7 is a little faster, I would still take AMD if its cheaper, i7 is too expensive right now.

They do not mean very little. They are just less important than they once were.

I hope for AMD that they are really back......but after all the failures I doubt it :/
#11.1 generic mike on 21 Nov 2008 - 20:44
I wouldn't say that they 'failed', but that they just didn't have the resources to keep up with Intel.

Perhaps aquiring ATI was a bit too much for their plate with the economic fall that followed, but I suspect that in the coming years that they will finally be able to (not catch up) streamline their compatability to produce results that will compete with Intel on a parallel but not similiar standing.

Why do you doubt it?

Intel was able to recover the failure that was the Pentium 4. I remember when my friend bought his Pentium 4 cpu. It was clocked higher than my AMD Athlon and was more expensive. We had the same gfx card and the same amount of ram and i was able to get a better framerate in games than him.

If intel can do it AMD too.

Btw AMD ATI was able to recover in the gfx business with the 4850 and 4870.

oh, I wasn't saying that they fell behind in the GPU market, I was just saying that it seems like they haven't been able to completely streamline it's too product like they wanted to yet. I speculate that it's going to be a bit longer than they planned b/c of the economic state.

If your not familiar with it's stream-lining plan, as i understand it, it's going to be a bit similiar to Apple in the aspect of their parts working smoother with each other than with another. I beleive they called it the 'spider' something.

Our Core i7 920 sample is stable at 3.8 GHz and with a bit more tweaking would likely stabilize at 4 GHz as well.

Jacob Freeman @ EVGA somehow manages to overclock the 2.66GHz Core i7 920 all the way up to 4.30GHz using just air cooling and the EVGA X58 motherboard!


keep in mind this isn't even nitro cooling, this is all on AIR

AMD = stock 2.8 / OC 4.0
Intel = stock 2.6 / OC 4.3
#12.1 gonchuki on 21 Nov 2008 - 20:42
Keep in mind that it's just the results of ONE sample processor as every chip will overclock to a different limit, and that we have no exact figures of IPC and clock scalability on each processor. It may turn out that the AMD @ 4.0 ends up being faster than the i7 @ 4.3.
#12.2 Recon415 on 22 Nov 2008 - 00:09
Also keep in mind that "EVGA somehow manages to overclock the 2.66GHz Core i7 920 all the way up to 4.30GHz using just air cooling and the EVGA X58 motherboard!" means EVGA, and not the average person. And also realize that EVGA's not going to be doing all the overclocking here.

So:

AMD = stock 2.8 / OC 4.0
Intel = stock 2.6 / OC 3.8

And also keep in mind that the chip is NOT OUT YET. So for all we know, EVGA could go OC it to 4.6 or something.

not out ?????

you can find them every where in e-tailers
#12.4 LaP on 22 Nov 2008 - 17:37
I love all those air cooling figures people post. For a strange reason i am never able to reproduce them in my own case even if i have a good Thermaltake Big Typhoon and 3 120mm fan in my case with modular cables for my OCZ PSU. Wonder how big the heat sink need to be is over the cpu to get such results ...

It's all "ooh" and "aah" for now. Just wait until we see the benchmarks. I really hope AMD has something good this time around.
#13.1 TruckWEB on 22 Nov 2008 - 01:27
That's what I'm thinking. Because, 30-40% better performance would probably not be enough to compete toe-to-toe with Intel i7. Since the Phenom was already slower than the Core2....
#14 psionicinversion on 21 Nov 2008 - 22:06
why are ppl bashing amd ooo 6 ghz it aint about megahertz and crap. yes it aint but they probably just demonstrating how resilient the silicon is and what the 45nm process is able to achieve.

I doubt the phenom 2 will beat the i7 but developing a true quad core processor architecture will have a few niggles with it at first. so once they iron it all out they can start improving on it which i hope is what theyve done with this processor. i reckon amd will start coming back with a there next few processors giving intel a run for the performance crown

I don't get all ya I have the 9600 quad on an asus m2r32-mvp two 4850 vid cards and 4 gigs of mem this takes anything I can throw at it all game run awesome no problems I'll probably upgrade on the 22 node when the new vid cards come out who gives a crap if intel has something faster oh wow it will finish a few seconds faster bid deal....
#15.1 skynetXrules on 22 Nov 2008 - 22:44
you dont went the extra power , doesnt mean no one went

or no one cares

and the differnce are big from C2Q too Phenom P.O.S.
#16 +Xerxes on 22 Nov 2008 - 04:39
Speed means nothing, Intel knows this more then most (when they went for pure speed back in the P4 days and got their arses handed to them by the much slower Athlons) It's all about how much work the processors do per cycle and at the moment the i7 is in a completely different league to anything AMD has. Can the "Phenom II" match the Core i7? maybe we know AMD are capable of it, but we'll have to wait and see cause right now boasting it can run at 5Ghz is all smoke and mirrors.
#17 devHead on 22 Nov 2008 - 05:30
Is that 5 Ghz per core? That's insane!!
#18 Drone_101 on 22 Nov 2008 - 10:14
Yeh and we all have nitrogen cooled rigs sat around waiting for things like this?

Just give me decent benchmarks while air cooled running your stock clock speeds at decent prices and I'll take notice.
#19 2Cold Scorpio on 23 Nov 2008 - 21:30
We heard this sort of talk about the first Phenoms (not going that fast mind you, I meant hype in general) and look how that ended up. I'm waiting for concrete benchmarks. Until then, I'm looking to get an i7.
#20 Tikitiki on 24 Nov 2008 - 01:15
nitrogen cooling for 5 GHz? C'mon now. What market are they aiming for? Super computing?
(1 reply) #21 Raiderman on 05 Dec 2008 - 02:01
People also put WAY too much stock in benchmarks... Benchmarking and real world performance are two different things. TBH, I really dont give a hoot whether you can encode a DVD 10 seconds faster than me! All I care about is AMD competing a little better against Intel for the plain simple fact of Pricing!
#21.1 iamwhoiam on 25 Jan 2009 - 09:49
Very true.

I used AMD for the better part of 25 years and finally went to the Intel Q6600 then to the i7 just recently. AMD will be back at some time and even if they don't compete directly with the latest Intel offerings, it will help to lower prices all around.

Whatever anyone thinks of either AMD or Intel, competition is good for us consumers.
