Computer CPU

CPU is a well-known acronym in the computing world, but what is in them? Learn more about CPUs, including the newest processors and the technology behind CPU speed.

As manufacturers struggle to find new ways to cram transistors on computer chips, it would seem that Gordon Moore's famous prediction will one day fizzle out. Should we retire Moore's Law?

Chasing Moore's Law requires a lot of research and development. Intel's Sandy Bridge processor architecture follows on the heels of Nehalem and Westmere chips. What makes Sandy Bridge different?

When people speak of supercomputers, they often talk about how powerful the machines are. But just what is computing power, and what makes one type of machine more powerful than another?

According to Moore's Law, computer processors double in complexity every two years. Is this really a law, and who is Gordon Moore, anyway?

Like clockwork, microprocessor manufacturers develop new and better chips to power our computers. What makes Intel's Nehalem chip so different?

Advances in technology have allowed microprocessor manufacturers to double the number of transistors on a CPU chip every two years. How long can they keep this up?

It takes a pretty big AC unit to lower the temperature of your entire house or apartment. And while you may not think about keeping your computer cool, it can overheat, too. Is there an air conditioner small enough to cool a computer chip?

Utility computing lets you pay as you go for your company's computing needs. Would you be willing to let someone else take care of your hardware and software?

People are switching to parallel processing to share big computing jobs between several smaller, less-expensive chips. But how does each processor know what to work on?

Instead of installing a supercomputer in your home, what if you bought many regular computers? That's the idea behind shared computing. But how does it work?

Silicon microprocessors are about to reach the limit to their storage capacity. But one technology may extend the life of the silicon microchip -- it's called extreme-ultraviolet lithography, and it may keep silicon useful for a few years longer.

When you sort things out and compare the two chips side by side, it turns out that a Celeron and a Pentium 4 chip running at the same speed are different beasts. You should choose a chip based on how you use your computer.

In this article we'll tell you which processor is faster and why. Learn how chip designers make use of transistors.

A microprocessor will perform without error when executed at or below the maximum indicated speed. Why can't they speed them up? There are two things that limit a chip's speed.

The microprocessor determines the processing power available for any application you run -- without it, there IS no computer. Learn all about this amazing, ever-shrinking technology that makes your computer compute.
