Is 2.16 ghz processor is better then the 2.4 ghz processor?

Processor speed is one of those tricky things that's really hard to grasp. Most retailers and computer junkies will refer to a processor's speed by the processor's clock speed (in Hertz, Hz). This is usually an indicator on how fast the processor will work. Unfortunately, that's not always true.

For example, a single-core 2.16 GHz processor will not perform near as well as a dual-core 2 GHz processor. In general, newer processors that have many cores will throw clock speed ratings out the window. (For a more accurate definition of speed, try to find out how many "flops", or calculations per second, a processor can do. This is more commonly seen on supercomputers.)

Assuming that these are both single-core processors, a clock speed of 2.16 GHz would be faster than a clock speed of 2 GHz. If either of these are multi-core, however, it's probably better to go with more cores.

Which CPU is manufactured as a multi core processor with one of the cores disabled?

Triple

Edit:

"Triple?" What does this mean? Triple core? There are Rana processors that are shipped as dual-core but have 3 cores on the die. This means that your answer is wrong.

The most common examples are triple-core processors, but not all of them. As for actual examples, Phenom X2-X3 and Athlon X3 processors are famous for having locked cores.

Processor speed is measured in?

Processor speed is benchmarked in terms of Hertz (Hz), or some derived unit of it (MHz = Megahertz, GHz = Gigahertz). It may also be measured in FLOPS, or Floating-Point Operations Per Seconds, or its derived units (MegaFLOPS, GigaFLOPS, TeraFLOPS, etc).

How can i test a CPU?

I would try running windows experience index if you have a PC.

What is difference between positive logic system negative logic system?

If you would like to perform an action by energising to act ( Logic 1 = desired output) then it's positive logic.

If you would like to perform an action by de-energising to act ( Logic 0 = desired output) then it's negative logic.

Here is an example for the positive and negative logic

POSITIVE LOGIC NEGATIVE LOGIC

o/p Y = 1 (energise to act) o/p Y = 0 (de-energise to act)

A B Y A B Y

1 1 1 1 1 0

1 0 0 1 0 1

0 1 0 0 1 1

0 0 0 0 0 1

any how the required action can be performed by using either a positive logic or a negative logic.

What is the purpose of using thermal compound when installing a CPU a heat sink and a fan assembly on a motherboard?

so the transfer of heat from the cpu to the heatsink is 100% even. If not the imperfections in smoothness of the heatsink's surface doesn't allow for an efficient and even transfer of heat. This reduces the efficiency of the heatsink condiderably. But too much is not good either. Just enough to create a thin layer as direct heat transfer

What was the original purpose of the microprocessor?

The emitter of a transistor was placed a micrometer distance between two, so it was called a microprocessor. Technology advanced, and the distance was improved to nano meter. Still, they call it micro.

What is the difference between a processor and a computer?

They are the same

Another Answer

The CPU (Central Processing Unit) is the core of any computer, while the microprocessor refers to the whole functional chip that is inserted into a motherboard. The CPU is the sub architecture of the microprocessor that interprets the program instructions and cascade triggers the sub-functions of each instruction.

What are cores on micro processors?

The "core" in a processor is the microprocessor inside of the CPU(Central Processing Unit).

For example, if you have a Dual Core CPU then you have 2 microprocessors inside of the CPU, this allows you to do two things at once, as a microprocessor can only do one thing at a time the only exception to this is Multi-Threading which allows one core to do the work of multiple cores, but its not as fast as having multiple cores.

How is a microprocessors speed measured?

Typically, microprocessors (like the ones found in computers), measure their speed in hertz. A hertz is the measurement of a cycle in a second. So, 10 hertz means 10 cycles per second.

In computing, a cycle (or, more specifically, a clock cycle) is the basic unit of measurement that the CPU uses to carry out instructions given to it by software. Therefore, in a CPU running at 900MHz, 900 million clock cycles will occur per second.

Software sends commands to the processor called, instructions. These commands are the basis for how all programs run on a computer and are handled by the computer in a very complicated manner.

However, a computer running at 3GHz, for example, is not performing 3 billion instructions per second. Some instructions take multiple cycles to complete and some can even have other instructions in the same cycle simultaneously.

To complicate matters further, it is not accurate to say that a higher speed processor is better than another one at a lower speed. Certain AMD processors, for example, run at lower speeds than comparable Intel processors of their family but, because they use different architecture, perform at the same (and, sometimes, higher) performance levels than CPU's with high clock speeds.

Also, processors with some sort of Hyper-Threading technology or, better yet, multiple cores (like Intel Core 2 Duo processors) will be rated at lowered speeds than other CPU's in their price range but, because of more than one (virtual) processor is running parallel to the others, more instructions are performed per clock cycle.

There are also a few more factors to consider but this is the gist of it.

Which processor is latest computer processor?

The latest trend in the processor technology is i3,i5,and i7 processors.these smart processors adapt to an individual's needs, automatically providing a 'boost' of performance for everyday applications. They become energy efficient to the point of shutting down processing cores or reducing power consumption to provide performance when people need it, and energy efficient when they don't."

What is a quadcore?

Intel Quad Core is one of the newer technologies developed by Intel for their consumer level Core 2 Quad and higher end Xeon processors. Basically, a quad core processor incorporates four processors onto one chip. In theory, you could see a massive improvement in performance from a quad core system but in reality, most programs, (and operating systems for that matter) do not yet support full utilization of all four cores.

How are microprocessors used in mobile phones?

Mobile telephones communicate with the mobile phone network using digital technology, yet the voice communication that still provides for the majority of mobile network traffic is purely analogue. A mobile phone must therefore convert voice communications into digital signals that can be transmitted over the network and it must convert digital signals received over the network into analogue voice data that can be heard by the mobile phone's user.

Who is the maker of AMD Athlon 64?

AMD is Advanced Micro Devices, Inc. located in Sunnyvale, California.

What are advantages and disadvantages of microcomputers?

Before the invention of the microcomputer, computer's were large, complex, and expensive, often occupying entire rooms. The microcomputer was much smaller, and could easily fit on a desktop. While they initially had limited processing power and memory, they were relatively cheap and become popular as home computers. From the 80's onwards, they became more and more powerful, but with the advent of the IBM Personal Computer and its compatibles, they became easier to maintain, highly upgradable and (gradually) more user-friendly -- making them ideal business machines as well as home computers. The term microcomputer isn't used very often these days -- it simply means small computer -- but it differentiates home and business computers from mainframes and supercomputers. Today, the need for desktop microcomputers is much less, however the term encapsulates laptops and other mobile devices which have begun to replace the desktop PC to a large extent.

The disadvantage of the microcomputer is the lack of processing power. While they are by no means under-powered for the tasks they were intended to fulfil, we still need mainframes and supercomputers for their superior transaction and mathematical processing abilities. So, ultimately, the only real disadvantage of a microcomputer is when it is used inappropriately.

What is the definition of CPU?

A CPU scheduler maximizes CPU utilization. It can do the scheduling based on two types, which is either a preemptive or a non-preemptive scheduling.

Can you replace a Intel atom precesser with a Intel atom dual core?

If it shares the same slot-type and the motherboard supports it, yes. In some cases, a motherboard will support a processor with a higher number of cores than was originally intended thanks to BIOS updates.

For instance, Asus M2N motherboards were originally released around the time that dual-core Athlons (Athlon X2) were gaining popularity. They supported single and multi-core processors of the AM2/AM2+ (slot) type by design. With the latest BIOS updates, they officially support AMD Phenom II X4 processors of the AM3 type up to the Phenom X4 945, and many users have had success installing 955s in these boards too.

If you are considering installing a dual-core processor in place of the existing single-core processor, it would be best to check the compatibility of your board with such processors before going further.
