Socket-939 Roadmap for 2004
Clock Speed Cache Size Release Date
AMD Athlon 64 FX-55 2.6GHz 1MB May '04
AMD Athlon 64 FX-53 2.4GHz 1MB Mar '04
AMD Athlon 64 4200+ 2.8GHz ??? H1 '05
AMD Athlon 64 4000+ 2.6GHz ??? Q1 '05
AMD Athlon 64 3800+ 2.4GHz 512KB May '04
AMD Athlon 64 3500+ 2.2GHz 512KB May '04
According to the roadmaps, the Athlon 64 3700+ on Socket 939 has been renamed to Athlon 64 3800+. Athlon 64 3400+ has been renamed to Athlon 64 3500+. Notice these changes are effective on the Socket 939 platform only. "The innuendo is that equivalently clocked Athlon 64s will perform better on Socket 939".
Socket-754 Roadmap for 2004
Clock Speed Cache Size Release Date
AMD Athlon 64 3700+ 2.4GHz 1MB Apr '04
AMD Athlon 64 3400+ 2.2GHz 1MB Already Available
AMD Athlon 64 3200+ 2.0GHz 1MB Already Available
AMD Athlon 64 3000+ 2.0GHz 512KB Already Available
AMD Athlon 64 2800+ 1.8GHz 512KB Q1 '04
AMD Athlon XP 3200+ TBD 256KB Q1 '05
AMD Athlon XP 3000+ TBD 256KB Q4 '04
AMD Athlon XP 2800+ TBD 256KB Q3 '04
However, the updated roadmap has a few surprises in store for Socket 754 as well. First of all, there has been the addition of Athlon XP 3200+ for socket 754. Athlon 64 2800+ will begin showing up very soon as the roadmap simply states Q1 for the release date. Since AMD has planned more Socket 754 processors (albeit budget oriented) the architecture is beginning to look much more forward looking than many originally expected. As we pointed out in the previous roadmap, the Athlon XP chips on the Socket 754 interface have a reduced cache and only run in 32-bit mode.
Of course the largest issue here is why the changes in the Socket 939 processors were made. It seems plausible that a new instruction set addition or optimization may give the Newcastle processors better performance than originally anticipated. Or perhaps the real answer is more mundane; AMD may have just renamed the processors to avoid confusion between Socket 939 and Socket 754.
Regrettably even though we know SSE3 instructions are set to start showing up on Athlon 64, AMD officials could not confirm upcoming release schedules for the technology.

Com os A64 3000+ a bater um P4 3.2 GHz em várias coisas, é normal ver a AMD a aproveitar-se e rotular um possível 3400+ num 3500+. O chato é que é só uma mudança de socket.
