Summary: The definitive comparison between apples and oranges.


Comparison of various graphics engines (all figures are approximate):

			Cray		Pixar		Amiga
			2		Image Computer	1000

Bits/pixel		0		48		6

Number of colors	1		1,073,741,824	4,096
displayed simultaneously

Number of pixels	0		8,388,608	64,000

Performance		1000		10-40		.5
(mips)

Hold And Modify		no		no		yes

Base Cost		$20,000,000	$80,000		$1000

FluorInert cooling	yes		no		no

---------------
Clearly, the Amiga wins hands down for mips per dollar.
However, the Pixar has an edge in colors per dollar.  The Cray
wins on FluorInert per dollar.  Any questions?

P.S. - The computation of "Luxo Jr" took around an hour and a half per frame
	computed on a CCI 6/32.  This is an
	improvement over previous times: Andre and Wally B. took from 7
	minutes to an hour on a Cray X/MP-48; the Young Sherlock Holmes
	effect took up to 6 and one half hours on a CCI.
