Thanks!<p>&gt; Those cores are going to be 
sold to you largely on their 
memory bandwidth benefits 
for the top end of the Xeon range.<p>That is, (A) <i>bandwidth</i>,
bytes moved per second or (B) 
total permitted memory size,
say, 1&#x2F;2 TB?<p>My guess is that memory sizes
of 1&#x2F;2 TB require <i>registered</i>
memory, that is, a <i>register</i>
in the memory to simplify timing
which can be challenging for such
large memories, but the use of
the register is an intermediate
stop on the way to&#x2F;from the processor
and its cache(s) so, really, reduces
bytes per second that might be
achieved with, say, the 
simpler, <i>consumer</i> 1600 MHz,
DDR3?<p>Of course, other issues could
include number of electronically
<i>independent channels</i> to&#x2F;from memory,
address <i>interleaved</i> memory,
etc.?<p>&gt; look seriously at IBM<p>I looked at the article;
IBM seems to be trying
to sell hardware (again!).
Okay.<p>So far my software is all
written for Windows, and
my guess is that Windows (7
Pro or Server)
doesn&#x27;t run on IBM&#x27;s Power 
processors?  And even if
Windows does run, lots of
other software that runs
on Windows and Intel
x86 likely won&#x27;t run
on IBM Power?
