2003-09-23 AMD Athlon 64 / 64 FX (Clawhammer) An "Opteron for the desktop", AMD64 (x86-64) chip previously known as Athlon DT or Clawhammer. Originally planned for October -02, later delayed to Q2, and launched in September -03 at Athlon 64 3200+ (2.0 GHz, $417), 3000+ ($278) and Athlon 64 FX-51 (2.2 GHz, $733).
Introduced with 1MB of L2 cache and two DDR channels in the 940 (later 939, incompatible to 940) pin package named FX.
The 754 pin package with only one DDR channel is the normal Athlon 64 and will be available with 1MB, 512KB and 256KB of L2 cache.

2003-04-22 AMD Opteron AMD's 64 bit extension to IA-32 aka Sledgehammer or Hammer. 0.13 micron chip using "HyperTransport" for internal data traffic, a NUMA (Non-Uniform Memory Access) bus to speed up large multiprocessor systems. The version with 1 MB of L2 cache includes 100 million transistors on an area of around 180 mm2.

Starts at 1.8 GHz and consumes about 70W of power. Later, 1.8 and 2 GHz chips will be released, followed by 2.2 GHz, 2.4 and 2.6 GHz. Server prices are rumoured to start at $3000 to $6000.

Three types available: 8xx, for up to eight-way servers, 2xx for dual servers and 1xx for single processor systems. The xx is a subjective performance number.

In April, Opteron 240 ($283), 242 ($690), and 244 ($794) was launched.
On 03-06-30 the 840, 842, 844 ($749-$2149), 140, 142 and 144 ($229-669) were released.
On 03-09-09 the 146 and 846 were released.
