This is what comes from not following the URLs.
The same holds true to a lesser degree, because even if the
CPU in a workstation is more important than in a server, still the
most important part(s) in a workstation isn't the CPU but are the
graphics adaptor and the system buses.

This is old stuff. It was never relevant in IA32 and S/390,
just a curiosity.
Thre are still lotsa organisations depending heavily on AIX.
And GNU/Linux in the Apples is simply a pain, due to unsupported
components like the softmodems and some units in the graphics
adaptors. Witness the G5 hasn't even a unit in the hands of
developers yet.

And?

This is just a small part of the story. Actually cache is
just to compensate slower memory and buses; make them faster and cache
gets less relevant. And this precisely has been one of Apple's
handicaps, and the reason why cache increases on Apples have been so
heartily cheered.
