On October the 19th, AMD officially launched the latest version of its successful Athlon 64 processor line, the 2.4GHz Athlon 64 4000+. PCstats spent a few weeks with this CPU prior to its release, and after running the silicon through its paces, we've come to a couple conclusions which we'll share with you in this review. These Athlon 64 processors share the socket 939 form factor with the high end Athlon 64 FX class, though as you will see later in this review, the line between the two is beginning to blur. To be specific, the Athlon 64 4000+ contains twice as much Level 2 Cache memory of the Athlon64 3800+. In other words, this chip is packing a full 1MB of exclusive L2.
