"There is dreadful news for Socket 754 owners; AMD is going to end the production of Athlon 754’s with its 3500+ microprocessor. You can expect to see 754 chips off the roadmap by the end of this year. For those looking to upgrade to a Socket 939 chip, AMD is expecting to launch their FX57 chip sometime mid-2005. The support for higher clocked Socket 939 chips and FX chips is on a positive outlook and AMD may even launch a FX59 this year. AMD also has no plans to break the 4GHz barrier, but they will most hit the 3GHz this year."

More here.

The Athlon 64 FX-57 (Q2) will be clocked at 2.8GHz.
The Athlon 64 FX-59 will be clocked at 3.0GHz.
AMD will also release their dual core Athlon 64 FX this year on Socket 940.

why are they ending it?

Because AMD can provide the same chips on Socket 939 for the same price.

and same chip, +dual channel = worth an extra 200mhz worth of performance on a754. 2.2ghz 754~2.0ghz 939.
Dual channel is really helpful for AMD, as their integrated memory controller removes any northbridge bottleneck.

actually isnt the last cpu for s754 the 3700+, thats what ive been seeing round from reading and stuff...

also for 754, the new line "Sempron" has taken over as a value processor like the durons, and celerons for intel were.... these semprons are so called crippled 64 bit athlons...

The Athlon 64 3700 is the fastest Socket 754 CPU.
I think, however, that dual-core mobile Athlon 64s will start on Socket 754 giving Socket 754 users the ability to upgrade to the next computing era.

The Semprons either use the T-Bred core (Athlon XP, Socket A) or one of the Athlon 64 cores (Socket 754). The Athlon 64 core Semprons have 64-bit disabled. All Semprons have 256MB of level 2 cache. The Semprons will soon migrate to Socket 939.
