Chizow, there's something slightly messed on that site.
For example (but not limited to):
They show
"2003-Q3 AMD Clawhammer-S Clawhammer successor built using a 90 nm process. Believed to start at 4400+ AMD rating-wise.." (Athlon64B ??)
and
"2003-Q3 AMD Paris Low price version of ClawHammer (Opteron 64) with smaller (256 KB) L2 cache." (Duron64 ???)
before
"2003-10-XX AMD Athlon 64 x86-64 chip, previously known as Athlon DT or Clawhammer, built with a 0.13 um process, for medium sized systems, "Hammer for the desktop". Rumoured start prices are at $400. Originally planned for October -02, later delayed to Q2, and now to September, ie after the Opteron launch. Will have 256KB to 1 MB of L2 cache."
