Since its introduction in 1992, the DEC Alpha has always been the fastest
processor, with only Hewlett Packard coming close. Since the demise of DEC,
development continues, but for it to maintain its lead throughout this
coming decade will depend on the continuing support of IBM, whose long-term
commitment is unknown.

For the prices on new Alphas, I quote the following from www.microway.com :

"From the 533-LX Performance Value to the 667MHZ SuperCache-8, Microway is
your best source for high-performance Alpha LX Workstations and Servers. LX
provides the most cost-effective platform for Tru64 UNIX and Linux. Prices
start at $1,995."

Yes, an Athlon 600 is cheaper than an Alpha 21164 533 MHz, and about half as
fast.

I am afraid there is a little more to porting an OS than having gcc for the
processor, especially as FreeBSD is not optimized for portability. FreeBSD
will be ported to the Itanium if people want to make the considerable
effort. So far the Itanium has been all promises and no substance.
