Subject: RAPTOR 3's Processer-Independent technology?

According to a performance comparison chart sent to me by DeskStation
Technology, a Raptor 3 workstation with the 5/300 (Alpha 21164/300) CPU
module installed is approximately:
61 times faster than an Amiga A4000/040/25
51 times faster than a Pentium 90
31 times faster than a Raptor IIA (Alpha 21064A/275)
So yes...it's speedy. (Is this the only 21164 based CPU out?)
Their brochure says this:
"SINCE THE DAWN OF THE COMPUTER AGE, YOU'VE LONGED FOR THE GREAT DISCOVERY.
A COMPUTER THAT COULD WITHSTAND THE TEST OF TIME, IMMUNE TO OBSOLESCENCE,
CAPABLE OF MORPHING ITSELF INTO THE THE DAY'S FASTEST, MOST POWERFUL MACHINE
FOR GRAPHICS AND 3D ANIMATION.
IN OTHER WORDS, YOU'VE BEEN WAITING FOR RAPTOR 3. YOU SEE, IT'S A COMPLETE
WINDOWS NT WORKSTATION WITH ONE SIGNIFICANT ADVANTAGE. IT'S PROCESSOR-
INDEPENDENT. WHICH MEANS UPGRADING IT IS AS SIMPLE AS CHANGING AN ADD-IN
CARD. NOT TO MENTION LIKE GETTING A WHOLE NEW MACHINE."
Raptor 3 Specs:
4 PCI SLOTS - (3) 32-bit PCI, (1) PCI/ISA slots
2 ISA SLOTS
2 32-bit PCI SCSI-II ports - (BTW, what's Windows NT disk striping?)
8 36-bit SIMM sockets for up to 1GB of main memory
Bus Width: 128 bit
Bandwidth: 150 MBytes/second
My question is: Does having the processor independent of the motherboard
really make the Raptor 3 immune to obselence?
The next generation of Alpha chips from DEC are supposed to run in the 600Mhz
to 900Mhz range (not exactly sure). So what specifically is it about the
design of the Raptor 3 that guarantees that CPU modules can continue to
be developed for it, and just simply plug in?
At what point does the design of the main motherboard itself become obselete?
Any thoughts you can share would be appreciated.
Thanks,
Dave
