That's actually really fast for 1962.

By 1980 the workstation market was thinking about 3M: A megabyte of memory (RAM), a megapixel display and a million instructions per second (all for less than a "megapenny"). -- https://en.wikipedia.org/wiki/3M_computer

OK, the machines of 1980 we're desktop sized rather than room sized, but, as Foone points out, the 7090 was also really a single-user (at a time) machine.

These days you can get a similar spec (within approximately an order of magnitude) in an Arduino: 8,000 or 16,000 kHz with 32kB (rather than the 7090's 144kB) of RAM.

Moore's law is strong but the applications are varied and sometimes the form factor is what changes the game rather than the raw specs.
