Depends how much of the chip is being used on trying to keep the
rest of the chip busy. With out-of-order, speculative, etc., the
overhead for keeping track of all of that is huge. If you packed
as many simple CPUs into a single chip instead, and let the OS keep
them all occupied, you may well get better overall performance per
chip.

(This would be for server/scientific stuff obviously - "typical desktop"
machines would not do well with such a design.)

That's how it looks to me, but then - I also think VLIW is a good
idea, so obviously I'm a kook. :-)
