@herderien: You will always be disappointed with your hardware after a certain period :p:. I don't think you will regret your investment, I think Phenom II will mainly be an interesting extra choice to choose from, which is all AMD needs and can deliver. Being really competitive with Intel will make Intel lower its prices and AMD needs the all the profit they can get. Still, I think I'm getting myself a nice Phenom II rig next year. IPC of Phenom II will most likely still be lower on Phenom II than on Core i7 and having an AM2+ platform is not very future proof either (AM3 will be and LGA 1366 of course).

i hope there are some Phenoms rated at ~65W tdp.

With a cheap 7xxG mobo its gona make an awesome cheap cruncher. :cool:

4 cores for ~250€ and moderate power consumption, hell yes!

moderate power consumption? :shocked::shrug:

your implying ~50W for the cpu alone is low?

that thing will run 24/7 and if the whole system consumes ~70-80W under full load (cpu), i say its moderate.

Low would be >30W.

and everything above 100W i consider as high.

Thought for my desktop rig i dont really care how much it uses, it runs less then 5h a day.

For a 24/7 rig every watt counts. One Watt = 1,6€ a year. :yepp:

You don't get my point.
All we know is that all listed phenom2 cpu's will have 125watt TDP, and when overclocked Deneb needs more voltage then Nehalem, as far as we know. So I don't see moderate power consumption happening with these chips. Even with lower clocked Phenom2 cpu's TDP's won't be under 95, an what's the point having a low clocked CPU?

A Deneb cruncher can be cheaper then a I7 crunchr, just because everything you need for a Deneb system will be cheaper. :D

All of the systems were running Crysis, which doesn’t put a heavy load across all four cores, but it does show that it the system was stable enough to run a big name title

yeah probably on air cooling and DICE running at 5GHz

crysis at 6.3GHz i just have a hard time believing
unless someone has heard something from reliable sources please take it easy with such statements before someone gets a heart attack :D

For the AM3 95W versions of Deneb
Watts=Volts*Amps
95=1.35*Amps
Amps=70.37

The voltage does not completely determine what power rating the cpu is. Depending on the load and the situation determines how much power the cpu will be pulling and the TDP is a theoretical maximum that any cpu will probably never hit until overclocked.

Now I think that the reason the voltage is so high on the AM2+ editions along with the 125W TDP is because of how the power regulation is done on AM2 and AM2+ boards. This is also supposing the AM3 chips will not be backwards compatible with AM2 or AM2+ boards. AM3 may allow higher amperage through the socket thus allowing for lower voltage because it seems that AMD does TDP based on the vcore going through the chips. 125W at 1.3v, 95W at 1.25v, and 65W at 1.2v I think, haven't paid attention in a while for 65W chips.

Take what I say with a grain of salt, I'm only a Comp Sci Major...

By the way, has anyone seen what they were doing with the northbridge while overclocking? I find it nice to know that the chips will overclock well and I will finally have an AMD that works well with my vapochill, but I really want to know how the nb scales with it because it helps with speed alot as well.

Stupid pet trick or not I would say that an AMD processor that not only posted, not only ran windows stable, not only ran stable loops of Crysis 2 demo, but did so at a stagering clock speed of something north of 5gHz (reported at something north of 6gHz) is almost unbelievable. A processor revision that not only killed the coldbug but blew the top of the best OC of the previous chip by better than 50 percent. Fanboi or no fanboi that is impressive. It is also apparent that some percentage of the retail parts will be fully capable of operating 24/7 in the 4gHz region. As a drop in chip replacement AMD is going to get some love from desktop and server users.

I understand that all the Phenom II (Deneb) parts are tdp of 95w at 2.8gHz and below. Whoops looks like the 2.8gHz am2+ is listed as 125w tdp, wonder if this has more to do with the am2+ MB/chipset or if they expect to get the tdp down in the am3 revision of deneb. Phenom II parts clocked at and above 3.0gHz are tdp 125w.Source zdnet Also Opteron (Shanghai) cores to 2.7gHz have tdp (acp?) of 75w. The Shanghai is just a Deneb in a server package. A 65w Phenom II is very likely, though I expect that they will all be AM3 chips. Looks like the last hura for the AM2+ is the 920/940

Having a choice for a performance PC is always good, go AMD :up:

No problem! Was just trying to keep the crap down. A blind man could see that wasn't a bash or slam against AMD and that that was an over reaction to nothing. Most folks here are hoping for something good from AMD! I remember you leaned to the AMD side at one time.

Phenom II drag races (LN OC) is OK but I'm looking for more 3.6 to 4GHz Air OC and Benchmarks to go along with it. MHz alone ain't enough as we found out with the P4:rofl:

That would be a nightmare only Intel employee want to see:( Realistically though, these processors will have apps the one will run faster than the others. Some apps will be better suited and run faster on one of these processors by differing spreads. The bickering will continue on as to which is more important or which matters the most.

IMHO, AMD would be stupid to pay nVidia to support their competition on THEIR platforms. AMD is laughing all the way to the bank. Even a High-end system features and Intel system they'll more than likely see matching video. nVidia gets left in the cold either way!

Personally we should be supporting companies who add NEEDLESS cost to products WE pay for. Still wonder why AMD is video card sales are better?

The other guy is right. Last time I checked, this was a CONSUMER centric forum, not a Fanboi site! I don't any Green or Blue in the title:rofl:

SLI liscencing is a non-issue. If AMD puts forth a good product and people want it then nV will either have to cough up drivers that allow SLI to the paying consumer or eat cup-o-noodles/macaroni and cheese for a while.

Well, I think AMD can with-hold specs for AM3, say for example, but nVidia will just stop making mobos and SLI on AMD platforms. Not a good deal either.

Well, to think of it however, you probably can get 2 AMD mobos, 1 with CF and the other with SLI, for the price of a nice(r) i7 board. No, not the cheap ($200+) ones where SLI is unavailable. :p:

Its a shame its taken AMD this long to catch up but atleast maybe they'll finally help drive down prices a bit.

What exactly (non legal) holds AMD back from enabling xfire on the nvidia chipsets? Is their implementation of the PCIE switch so different?

IIRC Blackbird 002 had a hacked BIOS or something that enabled both SLI and xfire. And apparently neither company complained about it - go HP?

You are right, they had a SLI rig running crossfire tho, not a AMD chip running crossfire, AMD is a bit easier giving away crossfire than nvidia is about sli. Either way that was a neat rig, Asus Striker Extreme 680i running 2900xt's in crossfire.

am3 procs are backward compatible, so you can put the next revision (ddr3 capable cpu's) after 920/940 also in any am2+ and also some am2. Power consumption has nothing to do with the mobo, although shanghai does support some new powerdown settings, it has nothing to do with tdp rating.

the deneb is just a shanghai in a desktop package btw :) not the other way around ;)

btw the early launch is indeed a 125W tdp, it doesn't state that they all will actually require that power, just like the recent blue team release.

All I can say is thank the heavens Deneb will work in AM2+, as a past 939 user the one thing that would have completely taken the wind out of my sails was if this was another pass standard tossout.

The now so famous 6+ GHz was done on a GA-MA790GP-DS4H....

Why are you ppl only looking af FX boards? The GA-MA790GP-DS4H is 790GX, obviously performs excellent with Phenom II, and even has worlds best onboard graphic's (there's a high-end feature for you right there lol).

Price is only € 125 in EU and about $140 in the US

http://geizhals.at/eu/a354907.html

So no more moaning about expensive boards please :)

There are many ways of paying less for the goods. It depends how much you are willing to spend or go far for it.

No one seems to like the Irish :(

An example would be the Asus P6T Deluxe originally found for $250 VAT included in the UK and $299 in USA, calculating it with the current exchange rate and a fair comparison (UK, US) the product end up being £200 + VAT which is almost 20% results at £240 so basically shops are getting less than 10% profit each unit , with my skills I found it priced for £210 VAT included, most of USA estates do not charge TAX so for my P6T Deluxe I paid 10% less than if I was in US because the tax was included.

There are many other ways like when I or friends travel around the world for holidays, working, business etc..

Opportunities and information are the key points.

You have to remember that we pay tax, so when making fair comparisons price to price, remove the tax of each country.

An Example: My recent purchase.

Asus P6T = $299 (USA no Tax)
Asus P6T = £180 (price I paid in the UK no Tax)

Exchange rate: $1.50 for £1

$299/$1.50 =£199
£180x$1.50 =$270

A good review is right here.

6x,8x and so on. It depends how you overclock.

I'm an XS user in the sense of pushing the memory latency down to the limits with significant speeds, my priority is to get the best latency and then the highest speed with that latency not to forget it has to be 100% stable for 24/7 operations.

An example: Crucial DDR2 777 with CL3 better than CL5 1066.

This is from my Buddies Milke M and Mike H (thanks for going the extra miles), this is a freak of statistic, this part is not in the middle distribution of the curve, it actually leak some serious current ... but it does OC, really, like hell.
6Ghz, i know i can do it already, let s see what is the next Digit :), and to make sure everything is fair, I ll be joining a master of OC, he knows better than I do about LN2 :)

I am just going to be doing the same as our green buddies, dissable the thermal control, and let s see :)

I ll drop the result here before thanks giving week end!
