CPU ceiling?

Yep, beyond that generates too much heat. In the middle 90s, Intel talked
about bio-chips, etc. by Y2K. That never happened. Intel kept upping the
CPU speed until they ran into a heat problem.

Fortunately, they had a skunkworks in Israel that came up with the
multi-core idea.

What Intel does beyond that to improve speed, I don't know but it seems the
aliens from Roswell are no longer around to advise them.

Well a radio oscillator can run over 300 ghz. Why can't a microprocessor?

Power.

This is an example of something that goes fast. You'd use this
on the front end of a fiber optic transmission system, to
bring the data rate down to something that silicon can handle.
(Serial to parallel conversion.)

"HBTs also have potential for the highest-speed
digital and mixed-signal circuits with clock rates
beyond 100GHz."

It has the speed, but not the gate density, to build processors.

It recently changed from "****tard" to "****turd"...

Well, I _could_ say that I've been involved with PCs since
IBM announced their version. Or I could mention that I build
and maintain my own machines. Or I could mention that I've
used versions of DOS from 3.3 to IBM's DOS 2k, Windows from
3.0 to XP pro 64, plus various flavors of OS/2 and Linux.

But I think I'd rather go with the available evidence and
conclude that you're off your meds.

Bullshit. More like a Third Worlder who has heard of that stuff
since he stumbled onto the Internet recently.

But the Linux part is believable...

Says a Linux Lunatic who thinks that the "Pro" in Windows XP Pro
means that it runs faster than Windows XP home. It says "Pro" so
it must go VROOM! Sure buddy, you are the expert...

Just because some third worlder cannot afford decent hardware,
does not mean that decent hardware does not exist.

Core 2 Quad Q9550, 2.83 GHz
Playing Forged Alliance. When using only one core, the one core
quickly maxes out and makes the game slow and choppy...Using
four cores makes it run smoothly
Click to expand...

In the attached/corresponding picture is what CPU activity looks
like when the game's CPU load is spread from one core to all
cores, using a tiny utility called "Core Maximizer" made by a fan
of the game. In full screen mode, the game goes from choppy to
smooth. With the game in windowed mode, the entire system
performance goes from slow to fast.
 
Following is another example, playing Supreme Commander 2. The first
pic is starting the game normally using all four cores. The second
pic is starting the game and using Windows Task Manager to jostle the
process priority, toggling core zero off and then back on. Still
using all four cores, just turning core zero off, applying the
change, and then turning core zero back on again.
