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.

Sorry long winded answer to a very small point! :eek:
One last point, you say, AMD's architecture is more advanced, that could be true, however, it means nothing if it cant compete, and sadly, across the board it cant compete.....now before you think it (if you havent already!) I was brought up on AMD, I love AMD and I will always go back to them.....when they become more competative.
good stuff man ;)
But time will tell, they have done it b4 ;)
Let it be known, I am not an Intel fanboy. I will switch back to AMD the instant they take the OCed performance lead. (Actually, I still have an AMD rig with a 6400+ in it. I just wish the damn board supported Phenom. :( )
But agreed that AMD is a bit slow in a few other areas, AM2 was not a big leap from the old 939 at all =/ shame tho, just like to see the new 45nm ones with the CPU's of intel today, i think it might be interesting to see ;)
Edit: also, according to AMD's site, the die shrink will in fact reduce power consumption and allow for better power management and usuage. This contradicts Xbit labs "prediction" as they have said themselves, merely a prediction, no supporting evidence.
What mobo you using with the 6400? O ris it only the AM2+ that take Quads?
As for my board, it's a DFI NF UltraII M2. They aren't supporting Phenom on it. Don't know if it's a bios limitation, or their choice tho.
