This sounds like quad units, which would be four singlecores or two dualcores 
(the 1024-machine Pixar render farm was installed in 2004, which predates 
quadcores, but they could have upgraded it since then).  "850 machines" suggests 
that multiple projects were being rendered at the same time; the system would 
assign portions of the farm to each project based on their priorities, and you'd 
expect the feature in work at the time to get the lion's share.
