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.

4.4Ghz is a bold claim for stock speeds. If AMD can deliver, this chip will be well worthy of the FX name. Its about time AMD :)

Looks like leftovers of the original Phenom marketing campaign.

This is good news for AMD if they can pull it off. I'd like to see them bring rivalry to Intel again.

from 2,6Ghz with 140W TDP in 65nm to 4,4Ghz in 45nm.. that is just impossible..
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?

Wtf, 5GHz stock clock(or 4.4). Thats awesome. I may have to sell my system to build a new AMD Deneb system.:rockout: Hopefully there not that expensive. This is good news for us non OCers to.

the step of 65nm to 45nm should bring 2ghz? thats to much..

and these slides of the Phenom FX are very old.

i would love to believe that, that is true

But since this is Socket AM2+ can't you just buy a AM2+ board now and it will support this?

Well that step reduced power consumption by around 45%...which means room to take the clocks higher. :)

Why, didn't the shrink from 90nm to 65nm allow the Cedarmill to sell at insane 3.80 GHz frequencies (and clock-speed records)? Compared to 2.80 Prescotts that were already hot? Ofcourse Cedarmill didn't lop down TDP as expected.


Those slides are of no relevance to this article they're just PR do's / don't s.

i have made already plans for my new rig with intel but seems is worth waiting even a half year till this new chips come out

let us bet :)

maximum 3Ghz..

Deneb has more Cache and a better IPC. At 4,4Ghz it would blow all availables cpus out of hell

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?

If true, then holy crap! If not than BOO!!! I would really like to see AMD back in the performance game, I have been waiting on this since the dang Phenom came out.
