64 bit Prescott CFLAGS

I have an Intel Pentium 4 HT which on closer examination I found to be 64 bit. I am running Sabayon on it fine but I would like to know what CFLAGS i would need to use. The CPU says its a Prescott with SSE3 (PNI) and EM64T. Can i use march=prescott -msse3 with CHOST="x86_64-pc-linux-gnu" ??? Or does prescott imply 32 bit? I also read that march=nocona should be used as per a Xeon.

Any thoughts anyone?

Nocona is the same as Prescott, its just called Xeon and the prescott P4.

The only difference, really, is that the Xeons may clock faster.

Late Noconas might have really high caches (4meg, maybe?) but 64-bit prescotts can have as much as 2meg of L2.

So yeah, Nocona and 64-bit Prescott are identical for all intents and purposes.
