Original AMD Athlon 64 core. This was found on both the Socket 754 and Socket 939 interfaces. The Clawhammer core featured 1 MB of L2 cache and ran a 800MHz Hypertransport bus. Furthermore, the Clawhammer was based on the 130nm manufacturing process. These processors ran roughly 20 - 30% faster than the Athlon XP Bartons at the same clock frequency.

Do not confuse the Clawhammer with the newer Newcastle core which is also on the Socket 754/939 but features only 512KB of L2 cache. The Clawhammer core was the original Athlon 64 and is the core for the Athlon FX series (53, 55).
Today I bought a Athlon 64 based on the Clawhammer core and it ripped apart the Intel Pentium 4 in all benchmarks.

God, that clawhammer couldn't hit the broadside of a barn if his life depended on it.

When your girl is on her knees going down on you, grab the base of your cock and guide your cock into her cheek. This is when you move quickly to one side dragging her with you.
