Sorry, Madison will intro at 1.5 GHz and will scale to
higher frequencies later on. Deerfield will be clocked
at a lower rate. How much lower depends on the power
dissipation target Intel and its OEM partners set for it.

Don't count on it. As I have said before, I'll be
surprised if Hammer gets above 2.5 GHz in 130 nm.

Opteron beating Madison on SPECfp2k?
Madison falling behind many other 64 bit MPUs on
SPECint2k?
