Limit to processor speed?

Isn't there a limit to processor speed?
I mean they cant simply go on bringing ever faster processors ?

There should be some theoritical limit to it. what is that?

Physics comes into play. Currently pretty much at the limit of current
technology.

LOL

Only a limit to current technology. You should see some of the tech they are
working on tho. Some amazing stuff. Hopefully, the race for mhz will start
to dwindle and true performance increases will prevail. AMD has been trying
this for a couple of years and showing quite successfully the flaw of the
megahertz myth. I would like to see Intel follow suit.

186,000 miles per second?

Not as such. Depends if you mean speed of crunching numbers or clock speed.

Why?

Why should there be?

There are certainly limits on the current lithographic type process used to
manufacture silicon chips in relation to feature size. AMD and IBM are
talking of 65nm fabs - half the feature size of current XPs. That'll come
after the 90nm fab due to be working at the end of the year (I think thats
current info).

But you can always do something different, think about it in an alternative
way and maybe make gains there.

It's actually 186,355 miles per second
(http://www.phys.virginia.edu/classes.../spedlite.html)

and in theory, you might be able to "cheat" and get around that speed
limit too depending on which physicists and theories you want to
reference.

I'm convinced that computer systems will get faster and faster, at least
within the next 20 years. Because one could always start to use processors
in parallel once we reach the theoritical limit. However, this will
introduce some overhead, so 2 processors won't be 2 times faster than 1
processor. And that means imho that there is ultimately a limit to speed.

Wasn't there rumors a couple years ago of a European company trying to
produce a slower MHz cpu with a very wide data/address bus. Something like
1024 bits wide?? The idea was their cpu would do as much or more work per
cycle than faster & narrower bussed cpu's.

I remember reading about that - in an article about the 8Mhz 286 processor.
