The transition of the K10 architecture by AMD to the 45nm silicon fabrication process is stirring up interesting revelations these days. First, it was about surprisingly low power consumption of the quad-core Phenom parts, and then about the overclocking headroom those 45nm parts provided, at least the engineering samples did so far. And now, news coming in that AMD could be resurrecting the "FX" series of extreme performance products. Over the past three or so years, the performance trail AMD products had over Intel's made it close to impossible for AMD to sell parts that provide performance tuning advantages such as unlocked FSB multiplier settings for a premium, like it did back when K8 reigned the performance segment. "Black Edition" chips made up for that deficit by providing consumers overclocking advantages while not charging a significant premium and at the same time, safeguarding the "FX" title, not letting it dilute.
Come AMD Deneb core and lot seems to be on offer. To begin with, unlike the Windsor core that had a maximum FSB multiplier of 16.0x, initial reports suggest the Deneb to sport a maximum 25.0x multiplier, 200 MHz x 25 = 5.00 GHz, with the FSB left to play with. Considering at 2.30 GHz the Deneb draws in 57.3 W (according to findings), it should still leave enough room for AMD to sell premium products clocked at high frequencies.
From Reviewage's findings, there seem to be two Phenom FX processors in the making. The numbering seems to take off where it last left at the Athlon64 FX 74. The two chips, Phenom FX 80 and Phenom FX 82 could be clocked at 4.00 GHz and 4.40 GHz respectively (stock speeds). An interesting statement is that at 4.00 GHz, the Phenom FX 80 should outperform an Intel Kentsfield core clocked at 5.00 GHz, implies it has to be faster than the Kentsfield on a clock-to-clock basis. This opens up an interesting debate on how these parts compare to the succeeding Yorkfield chips. This should also open gates for several models to enter the market at various clock speeds.

by: btarunrThat should make it better than a yorkfield, by a decent margin. I'll believe it when I see it, that's a pretty huge architecture improvement. Maybe in some very specific test and circumstance, but overall, that seems unlikely. Still, it would be nice if it were true, drop some prices and make things nice and competitive like the vc market. It would have to be soon though, as far as multi-tasking goes it's quite unlikely these things will stand up to nehalem, so it would be nice if they get out first...........
I'm not AMD, we're not betting. :)
It's claimed 4:00 GHz Deneb = >5.00 GHz Kentsfield. Shouldn't that take it close to the Yorkfield?
I really, REALLY hope this is true. I would love to start making money on my AMD stock! If a 4ghz Deneb = a 5ghz Kentsfield, I believe Deneb and Yorkfield should be close to neck and neck. We will see, I heard enough bs about Phenom before it was released.
by: btarunrMathematically heat output doesnt scale in a linear fashion. See the power draw of a QX9650:
That isn't 140W anymore. 9950 got a new rating of 125W. Besides some tests show 2.30 GHz Deneb operating at 58W. Why does 4.40 GHz look impossible...mathematically?
Doesn't have to be linear, just telling it doesn't look impossible looking at Deneb's 2.30 GHz wattage results.

Yep, that pretty much obeys the Law of Diminishing Returns. :P
After you reach a certain point, it takes more and more power to get less and less of a speed increase. It's the same way with cars.
Either way, even if this chip sucks a hell of a lot of power, it'd still be cool to see it perform. (Even Intel chips at 4+ GHz pull a hell of a lot of watts.)
4.0 Ghz for a Stock CPU is Unheard of , and will be awesome . I nelieve in AMD to come up with something . They have been down too long now, and when things get desperate, desperate companies take desperate measures and rise from the ashes to fly high .
Looking at that core voltage 1.168V ( Holy Crap ! ) . This has to be perfectly possible . Can an Intel cpu do 4ghz at that voltage ?
If this is true, bye bye nehalem , Spider Platform , here i come .

If this is true, AMD has done a great catch-up on Intel. But 4.0Ghz?? If that's out of box, they must pack a good cooler with them, not like that Prescott like cooler that idles at 65c:laugh:.
i want one saving for it now :D

You and me both! My Dream would come true. because i too have stock in AMD. :rockout:
Would consider to buy my first Quad Core if it's true =)
Why do you all compare this with kentsfield cores? nehalem will bash this rubbish :laugh:
by: hugzI'm not quite so sure. To me nehalem seems to be much like a hyperthreaded kentsfield, allowing more threads but not adding much horsepower.

A Phenom clocked at 4ghz stock however, is indeed a force to be reckoned with, if it does so exist.
I was saving to convert my system to nehalem, but by the looks of it, I might reconsider going back to AMD.
Bad choice AMD. Skip this generation, and go for better than Nahalem.
I saw somewhere trusted benchmark of QX9770 running at 4.6 Ghz +- getting bashed by 265$ 2.6 Ghz nehalem.
Nehalem also means $260 + < insert LGA 1366 / 1160 motherboard price here > + DDR3 (if you don't have)
Phenom FX gives you the option of
1. Using a AM2+ / possible "AM3" board single
2. Comes in Socket 1207 flavours
3. Use two chips on a dual socket 1207 board over DSDC. Different from server boards, design approach takes off from where NVIDIA nForce 680a left.
So effectively that $260 processor is $260 + X58 board price.
There's no such thing as "trusted benchmark", often we brand reviews/benchmarks that sync with our thoughts / choice / opinions as "trusted" while those that don't sync we brand as "this is the worst bench / review I've seen".
BTW, that SANDRA plot of QX9770 vs. Bloomfield 2.66 GHz had the QX9770 running at stock.

deneb cpu is not made to go head to head with yorkfield but is for the cut down version of desktop nehalem as the shanghai server 2P/4P/8P? cpu is for the high end nehalem.
AMD has already said deneb will beat yorkfield but has not said anything about it beating nehalem. Intel is in big trouble if nehalem does not do better then already shown.
am already selling my Intel set-up as its not going to be worth anything at todays value at the end of this year lol. :nutkick:

Interesting indeed...As I won't have the funds saved for the new build until Dec of this year or jan or feb of the new year, I'll have plenty of time to watch and see how these new "toys" pan out...Exciting stuff
you need 3 ddr3 sticks, x58 motherboard, nehalem cpu etc = 1000+
i just hope AMD don't make the same mistake last time (high prices)
deneb works with both ddr2 and ddr3

Since i dont OC its going to be hard to pick.
by: CDdude55That should make it easier, one less factor to vary in to a decision, plus all benchies are always done at stock. It will be an interesting fall......

One thing that does make this so exciting...AMD's vid cards...they just kick ass...AMD said they would and they delivered..Stands to reason that the "NEW" cpu's would follow suit...good times :-)
That`s the pic a seen a few weeks back ,Wonder if these will be in the mid $350 range?
please let it be so, i am so ready for this. go amd :toast:
by: H82LUZ73Less , AMD has to win back the enthusiasts to there side. The only way they can do this is by lowering the price like they did with HD 48xx series and won over all of you . Now you guys think 2 times before going Nvidia .

It is great for the market period IF this is true, AMD fan or Intel fan!
