[comp.arch] intel 860 and its applications

Since the introduction of Intel's very own 1M transister chip, i860, 
there has been quite a bit of interest. I read somewhere some companies
are developing workstations around it. Notably, Megatek was such.

Thus, the question is whether there are going to be computers built on
it by which company. 

Also, in its spec, it is said that ,using its special graphics instructions,
21 million Gouraud shaded pixels with Z-buffer can be processed. The question
is how they derive such number. I am sure that there are many of you who
have gotten weary at this type of guessing. However, if you have spare
brain cells to dwell on this subject, it would be interesting. 

I suspect that ,as it is said, they are pixels not polygons. This 
probably means that scan-line information needs to be processed beforehand.
Given 10x10 polygons, it can do 210K polygons at its peak rate. This 
does not include transformation and other house keeping such as dealing 
with edge pairs and all. 

Also, since i860 uses the write-back scheme for caching, is there a 
possibility to realize a multi-processor scheme for different types of 
graphics algorithms?
