That's not so mind blowing to me. If you want to run a GUI desktop
application or a TCP/IP server accepting thousands of connections,
then a 386 feels far underpowered. But if you're doing calculations a
40 (or even 20) Mhz cpu with fpu really can do a lot. Especially with
highly optimized code.
Sometime explore how much of the time our desktop CPUs spend in an
idle loop or performing NOOPs.
What's interesting to me is when I run across tasks that really do
start to give the cpu a work out. Recent ones I've noticed:
* photo slide show screen saver
* music player visualizations
* converting a video
Other than that, my laptop usually keeps one of the cpu cores turned
off and the other one on low power mode. I will note that its nice
having the dual core and speed step so that when you want the cpu
power its there. But most of the time the cpu sits idle waiting for
something to do.
