wonders how ARM did that - the MIPS R2000 came in at ~115k and the 80286 ~134k

anyway - say you want 50% of the transistors for on chip RAM these days, then thats

100 billion / 50 thousand = 2 million ARM 1s

clocking at say 3GHz

6e15 MIPS = 6 peta MIPS

so if you could run code on it, you would get a 10,000x speed up ;-)

A fairly deep dive into it

ARM1 has no cache memory, no hardware multiply and division, no MMU and no cache.
