The AMD Athlon 64 4000+ was the last single core Athlon 64 that AMD will make. The new AMD Athlon 64 X2 dual core processors will take over where the AMD Athlon 64 single core processor left off. The new AMD Athlon X2 dual core processors will start from 4200+ on up to 4800+ on the same core. With that said, The AMD Athlon 64 FX processors and the AMD Athlon Sempron processors will remain on a single cores.

Probably some price changes on the horizon for the entire AMD "fleet"? Asus A7N8X-X 1800+ @ 8 x 210MHz 768MB PC3200 Asus A9550 128MB/128-bit Gamer Edition WinME/WinXP Pro

Yeah I can imagine, but the slowest Athlon 64 X2 processor will start at 530 bucks when it's set to launch in June, which is more then the fatest Pentium 4 D processor. From what I have been reading the Athlon 64 X2 will smoke a Pentium D, thus is why the slowest Athlon 64 X2 processor will cost more then the fatest Pnetium D processor. I also found out that AMD made the Dual core processor 2 years ago, but they were waiting for the rest of the computer hardware to mature around it. So dual cores isn't as new as many think it is.

They never are cobra !!! These things dont get developed and put into production over night. Both Intel and AMD have been working on the dual core for the last 5 years. The both 64bit from Intel and amd have been on the shelve awaiting 64bit xp for 3 years. AMD chose to release theirs early, not sure why but the gamble worked.

Well I knew they already produce them in advance and let the hardware mature around it. Why did they release theirs to the public early? From what I read on of the main reasons why AMD Athlon 64 bit chips were released 2 years ago was mainly for so that beta could test Windows XP 64bit Alpha. Makes sense. Back to the topic. I wonder if the Semprons will eventually move on to the new Venice cores and become 64 bit in the next year or so. It wouldn't shocked me if that happened considering the older Semprons moved on to the old Athlon XP cores. I hear the 754 is near its death in production and all the newer Semprons will move on to the 939 socket soon. So it looks like the Semprons are slowly starting to make the move to be the only mainstream single core processor AMD will make in the future. I still don't know why the Athlon 64 FX series will remain on a single core until the new sockets come out next early year.

I think its going to get harder do predict what is going to happen from here on in, to be honest. I think the 4 ghz barier may prove to be more of a problem than perhaps first thought. I would suspect that heat may prove to be an issue, for both of them. The lga 775 has proved that even with the lower end clock speeds let alone the 3.8 or higher. When you look at it the p4 never ever ran at 50 C in the past, but now the standard temp is about 47 C getting in the old amd teritory. Just goes to show, that amd always had it right in the first place, but it was their hsf that let them down. My 3500+ sits on about 34 C at idle, but by gees it sings with XP64 on it, Im trying to get the final release out of MS but not having much luck at the moment. As for the FX I think that chip is about as awsome as it can get, suspect they may have pushed it as far as it can go, in current construction. But who knows. I wouldnt be at all suprised if we see a bit of a waiting game from here on in, if Im correct we might see something more early next year as we get closer to Longhorn. But I havent been keeping up with the latest in this field in recent times, been to darn buisy trying to develop and audit a web site, for a relative of mine.

Well as technology advances, the need for a lot of clock speed will decress. I mean, the G5's from IBM are a prime example of that. Sun microsystems is going to release a server processor in 2006 that is 1.1ghz but will be three to four times more powerful then the current top of the line server processor that runs at a much higher clock speed.
