AMD explains 4x4 architecture.
AMD has had a small "coming out party" for it's new 4X4 architecture. AMD recognizes that in order for true multitasking, you need two things, processor cores and high memory bandwidth. And so, AMD takes two A64 X2 chips, enables ccHT so the processors can talk to each other, allowing for extremely high memory bandwidth and four processor cores. At AMD's "coming out party", they showed 4x4 technology running multi-threaded applications very well, as well as two very intense applications running side by side. Assuming that a process is multi-threaded, 4x4 technology also allows for combining of the 4 cores to run one process, as seen in 3Dmark06.The monitor on the left represents an FX62, and the monitor on the right represents 4x4. The FX62 started first, and the 4x4 finished first. While 4x4 architecture won't exactly take the performance crown back from Conroe, it will certainly keep AMD in the game.

* Which is GOOD!
APK
P.S.=> This is good news for AMD fans, for certain, & for users in general, as imo @ least, it will force price breaks from BOTH sides probably (I hope so, don't you all?)... apk
Wait, that sucks though, more money to keep up with the cheaper Conroe ::scowl::
MUWAHAHAHA
God, conroes are a revolution.
:)
Still, it forces AMD to answer, & answer they are! We all gain by it imo, & hopefully it will make Intel step down pricing some.

* BUMS ME OUT, large, but I have NO SAY in it, whatsoever!
(Still, power consumption's been on the minds of the oem's of hardwares this past year, & you can bank on it that this is the driving force behind it... especially for datacenters!)

if you could have 4 cores all running the same thread..................
i'm shivering with excitement.
now, if only these things worked with 939 boards. i don't want to replace my 3800+ 939 with an am2 3800+
just think: quad core rendering in 3ds max 8...............
:D
This aint saying that they wont be competitvely priced as far as performance goes - AMD is already competitve in the low-end - but as far as clock-for-clock and MFlop-for-watt, gate shrink aint enough.
just like intel revamped their whole archatecture, its time for amd to do the same to keep ahead.
although i do think that the 4x4 platform is a satisfactory interm solution for us performance junkies, even if it does cost more than conroes. they have to stay compeditive somehow.
and the fact that it can run a single thread on all 4 cores is really kick ass. you can't do that on a conroe.
The K8 is just a suped up K7 afterall. and its way too early for a new arch. design, as this ones just starting to shine!!
That's where the K8L comes in... ;) K8L is AMD's answer to conroe...
as long as they can give me a high performance chip for a reasonable price, i'll be happy
i'm sorry, i've never really cared about cpu performance in 3dmark before recently because i couldn't OC
Properly implemented, the instruction-per-clock abilities of conroe and its shared cache (and possibly its intellingent memory prefetcher) as well as its better ooo execution coupled with AMD onboard memory controller could be the architecture to rule them all.. until the NextBigThing™ comes out anyway.
AMD itself doesent seem to sure about when its coming out though, one month its Q3 2007, then its Q4 2008, then its 2007 again... time will, as always, tell.
Personally I'm slightly concerned that at this rate Intel will be swimming in 45nm by the time K8L on 65 is out...
