In 1985, Intel released the 80386, a particularly complex and sophisticated microprocessor for its day, consisting of 275,000 transistors, a rather large number for the day.
How many transistors went into the accompanying 80387 floating-point coprocessor?
I’ve wondered about this for a long time — manufacturers don’t seem to communicate FPU transistor counts as readily as CPU counts.
The best I’ve found so far is a claim on coprocessor.info that the 80387 contained approximately 120,000 transistors (quite a bit more than the 8087’s 45,000 transistors).
