How do you calculate your computer system speed?
Speed matter when it comes to computing. With new computers costing upward of $1,500, you will naturally want to ensure that you are getting what you paid for. Computer speed can be calculated through a number of different ways, but all of these methods can provide a reasonable approximation of how fast your computer is running. Many of these methods can also let you know how quickly your computer is running when compared to similar models, letting you know whether you found a bargain or a lemon.
steps
1. Locate the basic speed of your computer by right clicking on the "My Computer" icon and selecting the option for 'Properties.' This will list the processor speed and onboard memory amounts of your machine, allowing you to see whether they match up with the promised manufacturer specs. Additionally, if you are running either Windows Vista or Windows 7, the screen will contain a general performance rating, allowing you to ascertain how capable your computer is of running the operating system.
2. Download the run the Sandra test (linked below in Resources) to determine how fast your computer's subsystems are when compared against similar models. You will be able to judge your computer's memory speed, hard drive speed, network speed, processing speed and all other salient characteristics of your machine. It will also allow you to compare your computer's results against the results of similarly equipped computer. The test itself is free to download, making it a bargain when it comes to calculating computer speed.
3. Use the SuperPI program (linked below in Resources) to calculate your overall processing speed compared against the most powerful computers in the world. The SuperPI program will calculate the number PI to 4,294,960,000 decimal digits, which will take most computers a fairly substantial amount of time.
These kind of devices could make communication with friends and people you know alot easier from home, they also make life easier, i.e : you can talk to your friends without meeting them using these devices.
Which has less number of instruction risc or cisc?
RISC stands for Reduced Instruction Set Computer. The design strategy of a RISC processor includes limiting the number of instructions. This does not mean that ALL RISC processors have less instructions than ALL CISC processors, but in general, they do.
What is the speed of the CPU meausured in?
There is no one measurement of CPU speed. Different CPU's may perform differently on various tasks. For instance, you might find something like this:
CPU 'A' runs program 1 in 5 seconds
CPU 'A' runs program 2 in 4 seconds
CPU 'B' runs program 1 in 4 seconds
CPU 'B' runs program 2 in 7 seconds.
It may appear that CPU 'A' is faster over all in this instance... But it may be the case that program '1' is run 100 times more often than program '2' which would make CPU 'B' the faster one.
There are some very complicated ways of actually figuring out which is faster, but that would require looking deeply into its architecture. And the problems your CPU will be working on. The best way to get an idea about what processor is actually faster is to look at sites that offer processor benchmarks such as TomsHardware.com. Otherwise you will be looking into MIPS (Millions of instructions per second.) along with GHz, and today you will even need to see how much a parallel architecture will speed up your program.
Don't let anyone tell you there is one simple number that will tell you how fast a computer is. Many people have tried to use GHz as a measure in the past, but this just isn't valid on its own. If you have 20 pipelines stages, your throughput will be lower for the same clockrate. The only time clock rates can be compared is between processors with the same architecture. (And I don't just mean x86 here!) They need to be developed with the same caches, branch prediction etc.
What is the normal temp for a CPU?
The temperature at the CPU varies from CPU to CPU, the best thing to do is to find your CPU model at Intel or AMD (more likely) look at the specs. and should tell you the maximum temperature it can handle
CPU speed is calculated off of the Front Side Bus (FSB) speed and the CPU Multiplier. Don't confuse HyperTransport (HT) or Quad Data Rate (QDR, aka Quad Pumping) with FSB. HyperTransport and QDR have "replaced" FSB, but they too rely on the FSB. FSB was formerly used as a transport medium for data between the processor, memory and northbridge chipset and is now used more just as a reference clock frequency.
FSB * Multiplier = CPU Speed
For example, my Sempron 3400+ runs at 2.0 GHz with an 800MHz HyperTransport bus. It runs on a 200 MHz FSB bus and has a multiplier of 10. The HyperTransport multiplier is 4.
200 MHz FSB * 10x Multiplier = 2,000 MHz CPU
200 MHz FSB * 8x HT Multiplier = 800 MHz HyperTransport bus
What is the Difference between microprocessor and chip?
the IC that is organized as a single-chip microprocessor contains only CPU without the other peripherals like ROM, RAM, and I/O ports that comprise a microcomputer, while the single-chip microcomputer is the chip that contains all the components that give the capabilities of the microcomputer.
How much does a processor cost?
Depends on what you are buying.
Small embedded processors can be purchased (in large quantities) for well under $1 (many are available for about 25 cents).
Very sophisticated processors may run into the thousands of dollars each.
Mil-spec or aerospace rated microprocessors can easily reach into the tens of thousands of dollars each.
What are control words in microprocessor?
to initialise the chip in microprocessor....that is for which purpose we are going to use it......
List three factors need to consider when upgrading processor?
Clock speed, MIPS (if such information is provided), how many cores, and socket.
But all depends on what you really want to use it for. You won't need more than dual-core or a quad-core if you're just gaming (most programs and games don't use more than one).
However if you're into the content-creation industry (video editing/producing, YouTube or other video sites) or if you run a business that requires business-grade servers, then more cores will definitely help with rendering times and load balancing.
What is the term for when two processors are employed in a computer?
Word pad and PowerPoint i think it is sorry if i am wrong
What is level 1 2 and 3 cache?
; L3 Cache (Level 3 Cache) This type of cache is becoming more prevalent as microprocessor manufacturers ship more processors with L1 and L2 cache built into the processor. L3 cache is then the extra cache that sits on the motherboard between the processor and main memory, since the processor already contains L1 and L2 cache. Some processors are starting to ship with L3 cache built-in as well to speed up memory operations further. In those cases the L3 cache often sits on a separate area of the die, not built directly into the chip core.
What is the multiplier if your front side bus is 133 MHz and your processor runs as 2.53 GHz?
Im guessing your multiplier would be around 19x or so, you could check this by entering your BIOS at startup and checking in there.
Ususally to enter the BIOS you hit one of the following:
-Esc
-F2
-F10
-F12
-Delete
One of these usually enters the setup.
How is a CPU different from a motherboard?
The Central Processing Unit (CPU) is the chip that actually performs the calculations that drive a computer. The motherboard is the board on which the CPU sits, and has the bus on which data is passed to the various input and output sources. Motherboards also usually contain slots for accessory cards (sometimes called daughterboards) such as a video card or network card.
The motherboard would be considered the nervous system, arteries and internal organs of a computer. The Central Processing Unit (CPU) would be considered the brain of a computer.
In a processor these are 120 instructions Bits needed to implement this instructions?
Log2 260 is 8.022, so it would seem that 9 bits are required to handle 260 instructions. In practice, however, the opcode is a multiple of 8 bits, so most instructions are 8 bits, with a few being 16 bits.
Will a intel Dual core e3400 2.6ghz Processor play top end games?
This processor will play a big part in playing top end games yes but you will need a good graphics card also.
Where is the cmos battery located in a Compaq Presario R3000 Laptop?
After taking apart the laptop (see instructions at
http://www.takeitapart.net/forum/index.php/topic,5.0.html) I found there is a CMOS battery under the keyboard, but it is soldered to the motherboard. This doesn't make it useful as a reset. I did not find a jumper or any other reset switch internal to the laptop. My research seems to suggest that holding the power button for 30 seconds is supposed to reset the CMOS. Unfortunately, that did not help in my case, but may for yours.
Regards,
JC

I have a dual core 1.6 ghz processor would i be able to play a 3 ghz single core game?
Sorry, but no. It doesn't mater how many cores it has, a 1.6 is still a 1.6.
Is processor speed measured in GHz?
yes it is,
the term hertz represents repetitions per second, ie, a 3000 hertz processor makes 3000 calculations per second. the term hertz also refers to anything that follows a cycle a computer screen refreshes at about 70 hertz, or updates what you see 70 times a second
Absolutely false on both accounts!To answer the above question, "Is speed of CPU is measured in hertz?" - the answer is NO! The performance of a CPU is approximated by a multitude of different criteria including specific testing programs depending on what functionality of the CPU specifically needs to be tested and measured. This overall performance can widely vary depending on the testing program, all supporting hardware and the preconditions of the testing environment.Regarding the original answer, these are all too common misconceptions these days! Unfortunately, you'll see ill advised reference to this throughout the periodicals, both on-line and off and even the marketing departments that desire to make the technical "jargon" more palatable - but not necessarily accurate.
The metric of "speed," which involves physical movement, has absolutely NOTHING to do with frequency measured in hertz. The two are NOT the same thing and are not interchangeable. A high school or college physics class will also prove this. You certainly don't get in your vehicle look at the speedometer and read 750 MHz or 3 GHz. Conversely, I've yet to see an actual laptop or desktop personal computer get up and physically move around the room or the house! It even seems silly!
How about some on-line proof? Check out the definitions on Wikipedia and elsewhere as cited below:
http://en.wikipedia.org/wiki/Speed
(Notice that nothing is stated about computing)
vs.
http://en.wikipedia.org/wiki/Hertz
http://en.wikipedia.org/wiki/Clock_rate
http://en.wikipedia.org/wiki/Frequency
Also reference the following:
Megahertz, for example, is defined as MHz, kilohertz as kHz and hertz as Hz. It is, in fact, ALWAYS a capital "H" to pay homage to the German Physicist Mr. Heinrich Hertz. Consider:
http://www.ideafinder.com/history/inventors/hertz.htm
or,
http://searchnetworking.techtarget.com/sDefinition/0,,sid7_gci214263,00.HTML
(Scroll down and notice the table) or,
http://tf.nist.gov/timefreq/general/glossary.htm
(Click on "M" or "J-K" - these folks should know the difference)
Want further proof? Take a look at, www.fcc.gov and note their frequency references. In addition, simply take a look at a stereo dial, clock radio or even your transistor radio and notice how the manufacturers abbreviate frequency. Notice that this has NOTHING to do with "speed." You don't tune your radio to a different "speed" nor do you head down the highway at 2 kHz or 3.2 GHz.Obviously, they're not interchangeable! The point is they're entirely different metrics.
In addition, the above claim that "a 3000 hertz processor makes 3000 calculations per second" is also false. Different processor manufacturers such as AMD, Cyrix(former), NEC, TI, Intel and others manipulate various calculations and instruction throughput differently. Depending on what specific instruction is being executed in the processor, it may take from a few cycles to several processor cycles to finish the execution of any particular instruction. Meaning, it is NOT a one-to-one ratio in relation to the clock rate! In other words, a 3 GHz microprocessor does NOT execute 3 Billion instructions (or calculations) per second!
What is the most common CPU speed?
This can be measured in a lot of ways. Typical for some categories listed below:
Typical home-end clock frequency is 3.0-3.6 GHz without any kind of overclocking.
Typical MiPS is averaging nearly 100,000 (This is getting phenominal!)
Processors are approaching the TFLOP level on the home-end as well.
IPC is 30~ for AMD and 50~ for Intel.
The last 3 are far more important in determining a processor's speed than the clock frequency.
Does the Asus A8V-VM motherboard support any dual-core processors?
Yes. This motherboard supports the AMD Athlon 64 X2. I believe the Athlon 64 X2 4800+ is the fastest processor this board will support.
