The Hammer will have full SSE2 (what makes the P4's fast) as well as having
its own memory controller on the chip(memory latency reduction of near half)
larger caches (more memory latency reduction) as well as a full Athlon
weight FPU. AMD claims that 25% or better perfomance than the AthlonXP
processors, and benchmarks that are floating around show it doing SSE2
applications at about 180%-200% faster than a P4(based on 800 Mhz hammer
pilot systems Vs. 1.6A Northwood P4) otherwise, it should perform at about
the 3.2Ghz P4 level with the chip running @ 2Ghz or so. No one has any Idea
about the cache sizes, as AMD has some NDA clamps on most of the info.
Also, the memory for the Hammer (named Opteron, FYI) will be 128bit DDR,
using 2 channels of standard DDR(most likely registered) Each chip in a MP
system will have its own memory bank, but the memory will be shared by all
the processors.

Subject: Mersenne: AMD Hammer
I have heard that AMD is making a new 64-bit chip called Hammer
early
next year. Will that allow an increase in testing speed similar to what
we
saw with the Pentium 4?
