(2) (Hammer) The code name for AMD's 64-bit CPU chips using 0.13 process technology. The Sledgehammer was introduced as the Opteron in 2003 for servers and workstations, and the Clawhammer began as the AMD Athlon 64. Designed for different markets, the Athlon 64 processor contained one HyperTransport link while the Opteron came with three.
Using silicon-on-insulator technology (SOI), the Athlon and Opteron versions of Hammer provide backward compatibility for all 32-bit software that has been running on PCs since the mid-1990s. In 2002, Microsoft announced Windows support for these 64-bit chips. See
