AM2 \> 939 \> 754

yes i left out the 940, but look up what they are and you’ll see why 🙂

Socket 939 processors support 3DNow!, SSE2, and SSE3 (revision E or later) instruction sets. **It has one HyperTransport link of 16 bit width that can run as fast as 2000 MT/s**. Processors using this socket have 64KB each Level 1 instruction and data caches, and either 512KB or 1 MB Level 2 cache.

ugh i really don’t wanna spend 20 minutes explaining this…

939, is newer technology, just read the wiki article.

oh here is an easier thing, i just for some reason over read

> Socket 754 was the original socket for AMD’s Athlon 64 desktop processors. Due to the recent introduction of newer socket layouts i.e. Socket 939 and AM2, Socket 754 has become the more “budget-minded” socket for use with AMD Athlon 64 or Sempron processors. In comparison, it differs from Socket 939 in several areas:
> 
> ```
> * support for a single channel memory controller (64-bits wide) with maximum of 3 DIMMs (no dual channel support)
> * lower HyperTransport speed (800 MHz Bi-Directional, 16 bit data path, up and downstream)
> * lower effective data bandwidth (9.6 GB/s)
> * lower motherboard manufacturing costs

> Although AMD has promoted Socket 754 as a budget platform on the desktop and encouraged mid and high end users to use Socket 939 (and recently Socket AM2) instead, Socket 754 remained for some time as AMD’s high end solution for mobile applications i.e. no Socket 939 Athlon 64 CPUs has ever been marketed as a mobile processor. Recently however, Socket S1 has been released and is slated to supersede S754 in the mobile market through its support for dual core CPUs and DDR2 RAM.
