Phenom FX in the Works, AMD to take Another shot at...Kentsfield
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.

also look at AMD's die shrinks now 130nm 2ghz=90w 90nm 2.8ghz=90w 65nm 2.8ghz DC=65w 2.5ghz QC=125w
so it is possible for a huge TDP drop to happen
check the link i found... preview for a deneb early engineering samples(could be fake... don't stone me to death yet)

i think it will be better if someone can translate all the jibberish in english from the native page on the hardspell.com
Our test already proved that 45nm Phenom may save near 40W under the full-load conditions compared to 65nm Phenom the power loss, scope close half, this result is very satisfying.
Sorry if the english is bad,its from the translated link,last page.
His overclocked results with undervolted cpu suggest the phenom is capable of more than mainstream setups have been getting out of it. Granted his top cpu speed isn't extraordinary, but the voltage he achieves these results at is far far better than stock.
Tye
no 4 and 4.4GHz :(
Also add the M3A78-T and the Sept-Oct release of the M3A79-T (above board with SB750)
I guess we will have to wait and see if there will be an fx phenom.
btarunr i win:cool:
we've been waiting for this for a while now.....
(Wonder if it will work on my Kna2plat):ohwell:
these are the OEM that will be 3.2 ghz but the mighty FX will be at least 1ghz higher, no doubt about it (4ghz)
the only doubt is the power it needs (1.168v or 1.475v) or maybe in between these figures.

if you look at the revision, its old news and at least 5/6 months old, the recent is b1/c1/?
