The Athlon 64 X2 is the first dual-core desktop CPU manufactured by AMD. It is essentially a processor consisting of two Athlon 64 cores joined together on one die. The cores share one dual-channel memory controller, are based on the E-stepping model of Athlon 64, and depending on the model have either 512 or 1024 kB of L2-Cache per core. The X2 sets the Hyper-threading flag and is also capable of decoding SSE3 instructions, so it can run and benefit from software optimizations that were previously mainly designed for Intel processors only.

AMD officially started shipping the Athlon 64 X2 at Computex, on 1^st June 2005.

It has been rumored that AMD plans to ship Quad Core chips in Q1 2006. [1]
