[Year 12 IPM] An interesting fact

[Roland Gesthuizen]

Here is a thought. A calculator used by a student requires only a single
operation, so its response time will not exceed that needed by the operator.
A response time below 0.1 second is experienced as instantaneous by a human
operator. A student calculator thus operates at about 10 FLOPS.

Should people be worried?

Regards Roland

Subject: [Year 12 IPM] An interesting fact

 From the latest copy of Australian Personal Computer, I was surprised 
to read, and my kids were dumbfounded to hear...

* A 1989 Cray 3 supercomputer could do 5 gigaflops (floating operations/sec)

* A Pentium 4 3.8GHz CPU does 15 Gflops

* An NVIDIA 7800 GTX video card does (wait for it) 169 Gflops

So, d'ya reckon Intel might be a mite worried?
