The B5000 was slower, but had a more advanced architecture. That 100,000 figure makes some significan assumptions about the instruction mix. For the faster instructions it could get almost to 500,000/s.

At 100,000 instructions per second, the 7090 wasn't all that fast. Pilot ACE, in 1951, could execute 15,000 instructions per second.
