They are two different companies. Cyrix is a smaller company, their processors are not as performant as Intel ones, however they would exponse exactly the same set of instructions. Regardless the lack of performance compared with Intel, Cyrix had a very good market in the mid 90s, for people that did not have the money to purchase Intel. Instead of purchasing an Intel at 166 Mhz with 400 dollars, one could purchase a Cyrix at 150 Mhz for only 99 dollars. Of course, the performance of the cyrix would be far smaller, but the price difference would make it worthwile. Had a Cyrix between 97 and 2000. Was very happy with it.
Pentium MMX, AMD K6, CYRIX M2
A Cyrix processor typically has much lower performance than an Intel processor of a comparable speed. The only main advantage that Cyrix has is that their processor run much cooler and draw less power than most Intel processors.
VIA (owner of Cyrix processors)
Socket 7 is used by the following processors: * Intel Pentium (75 MHz to 200 MHz) * Intel Pentium MMX (166 MHz to 233 MHz) * AMD K5 (75 MHz to 133 MHz) * AMD K6 (166 MHz to 300 MHz) * AMD K6-2 (233 MHz to 550 MHz) * AMD K6-III (350 MHz to 500 MHz) * WinChip (180 MHz to 250 MHz) * Cyrix 6x86 (100 MHz to 233 MHz) Note that most Socket 5 processors can also be used on a Socket 7 motherboard.
Dual voltage is used by Pentium MMX, Cyrix M2, and AMD K6. One voltage is used for external operations and another for internal operations.
some graphic processer are: intel(pentium,class p5 and p6), centaur (IDT-c6,class p5,),cyrix (6x86 class p6) and AMD (k6 class p6)
Cyrix's population is 300.
AMD, Intel, Cyrix
This is a bit of a confusing question. IBM-Compatible computers are a type of microcomputer themselves. Any x86 based processor, such as AMD, Intel, VIA, and Cyrix, are IBM-Compatible. Other systems also exist, such as older Macs which used IBM PowerPC processors and Motorola processors. There also exists Sun Systems SPARC processors, and a whole host of others. IBM-Compatibles are the current dominant consumer system.
Nothing; it's a brand name. Intel chose it because they had lost cases where they attempted to assert brand name ownership of "286", "386", "486" and related usages like "80x86" - courts decided, repeatedly, that these were generic terms for a type of architecture and not a product name (which would have been protected). Intel wanted this kind of protection because there would be nothing to match a Pentium, on release, for a long time (on the PC platform) and they did not want other manufacturers (e.g. AMD, Cyrix, VIA) being able to later claim that their products were "Pentiums", as had happened with the previous Intel releases, and so capitalize on Intel's marketing.

There are several companies that have made microprocessors. National Semiconductor, AMD, CYRIX, Texas Instruments, and Motorola are just a few examples.
AMDs 'dual core' CPUs, those that contain 2 CPU cores, as opposed to the 1 CPU core found in earlier AMD (and intel, VIA, cyrix etc) CPUs. Dual core CPUs have much better multitasking performance than traditional single core CPUs.

x86 is a generic term referring to the "instruction set" of the most successful CPU "architecture". The architecture is defined as how the CPU arranges and uses resources such as RAM and I/O. Intel invented the x86 architecture, and AMD, VIA, Cyrix and others have manufactured chips compatible with x86. CPU's read bytes from RAM as instructions and do stuff based on that data, this is how programming ultimately works. All computer languages eventually have to be translated into this data, called machine language. A byte is a number 0-255, and the set of byte values and their corresponding instructions forms the instruction set. There are many different types of CPUs that adhere to a specific philosophy, and therefore each major type of CPU has its own instruction set that is not compatible with a different CPU. Other types of instruction sets include MIPS, PPC, ARM, 6502, Z80, 68000, and others. The two main types of philosophies are CISC (Complex Instruction Set Computing) and RISC (Reduced Instruction Set Computing). CISC packs more "power" into each instruction but requires the CPU to be slower and more complicated, RISC makes each instruction do less but makes the CPU cheaper and faster. x86 is a CISC CPU (as were most in the late 70's/early 80's when x86 was born) with RISC extensions. x86 as a name comes from Intel's numerical designation various chips in the architecture. It begins with the 8086, and then 80286, 80386, 80486, and onward through the Pentium chips, Core line and beyond (often called "686" chips even though they no longer have numbers). To summarize, x86 is a term referring to the way that the CPU in the common PC was built and how it functions.

ToolsWhen putting the computer back together (or disassembling it for that matter), there are some basic tools that you'll find handy. Of course, you'll need your ESD protection equipment and a Phillips screwdriver (keep a flat-head screwdriver nearby, too. A small flashlight and a magnifying glass may come in handy, as well as needle nose pliers. A useful device for any kind of computer work is a small srewdriver with a Phillips head on one end and a flat-head on the other (I have no idea what the proper name is for the tool). Once again, you're not in a race. A good carpenter measures twice, and cuts once. When working on computers you want to double-check everything you install or connect. Before you start, make sure you have taken all your ESD precautions. As you continue, make a conscious effort to remain aware of these precautions.The Power SupplyA fairly basic installation, just lineup the holes and screw it on. Don't plug it in yet. Remember, the cable going to the remote switch on the front of the case carries 110 volts AC. If you took the wires off the switch, make sure you connect them just as they were before (I hope you documented). A wrong connection here can burn up your PC. After your power supply is installed, do not plug it in, you may not be able to tell if the switch is on or off and you don't want to turn the power supply on without a load.The RAMDIP memory modules are the hardest to install. Luckily, it's not done much anymore. SIMMs are inserted at about a 45 degree angle then stoand up until they clip into place. If they don't clip in properly, maybe you have them in backwards. They'll usually have a key cut into one side. DIMMs are keyed on the edge connector side, they can only be inserted one way. Once they are lined up, push them down until the locking tabs on the side come up. You may have to support the motherboard from underneath if it looks as though its going to flex too much. COAST modules are also keyed on the bottom and insert much like an adapter card (Coast On A STick memory is cache SRAM).The CPULuckily, CPU sockets aren't friction fit anymore. If you have a PGA Central Processor (Pentium MMX or Celeron, Cyrix or AMD), it will fit into a ZIFF (zero insertion force) socket. Pin#1 on the chip has to be lined up with pin#1 on the socket. This can be indicated on the socket with an arrow, a #1 silk-screened on the board, or a flattened corner. Usually the CPU will indicate pin#1 with a flattened corner (and, or a dot on top, and, or an arrow on the bottom center of the chip). Unclip and lift the handle, insert the chip, lower the handle and clip it in. If it's a Pentium II or a Pentium III, it will fit into a Slot 1 socket. These are rectangular in shape and have 242 pins in two rows. They're keyed, and the cartridge should only fit in one way. Check any documentation that came with the motherboard or CPU, and refer to your notes.The MotherboardMost PC cases will allow you to remove the metal tray that the motherboard attaches to by removing 2 or more screws. If you didn't do that during disassembly then you should familiarize yourself with it now. The plastic standoffs on the motherboard are to keep the solder-side of the board from touching the metal case and shorting out. Usually, it's better to install the RAM and CPU first to avoid the possibility of flexing the board and cracking solder connections or traces. Orient the motherboard properly and either clip in, or slide in the standoffs until the mounting screw holes line up. Insert the screws that hold the board in place. The screws need to be snug, but do not twist them into the motherboard. You may be able to connect the power to the system board as you install the tray. A power supply with a baby-AT form factor will have two motherboard connectors (P8 and P9). These connectors are keyed but can be reversed. Make sure the black wires on the two connectors are beside each other. Clip the keyed edge in at an angle, then straighten the connector up and slide it on. ATX power connectors slide in until the tab clicks. Once the motherboard and tray are secured in place, you can re-install the wires for the front of the case (refer to your documentation).At this point, you can install the video card. Do a final check on everything installed. Re-check all installations and connections, attach and plug in the monitor. Turn the computer on. Watch for lights on the front panel. How far does the BIOS POST routine get? Are there any error messages? Is this expected?
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 secondAbsolutely 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/Hertzhttp://en.wikipedia.org/wiki/Clock_ratehttp://en.wikipedia.org/wiki/FrequencyAlso 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.htmor,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!
1 - Firewire headerFirewire is also known as IEEE 1394. It is basically a high performance serial bus for digital and audio equipment to exchange data. The technology preceded USB but yet is faster than any current USB port. Often used for transferring digital video to the PC straight from a digital camera. The FireWire header onboard means you can install a FireWire port on your machine. Again these cables are often supplied as an optional extra which you will need to check with the retailer to see if they are supplied with your board.2 - PCI Express 16x slotsNow the most common slot for Graphics cards, the PCI Express 16x slots provides 16 separate lanes or data transfer. PCI express 1.0 slots offer a data transfer rate of 250MB/s the second generation of PCI express (PCI Express 2.0) offers twice the data rate at 500MB/s. Currently in development is PCI Express 3.0 which offers 1GB/s of data transfer. PCI Express 16x slots are also the basis for both SLI and Crossfire multi graphics card setups. With the increasing demands graphics cards are putting on systems, no less than a 16 lane slot will be good enough for any modern graphics card.3 - PCI Express 1x SlotLike the PCI Express 16x above the 1x slot uses exactly the same system but only has a single lane of serial data transfer. These slots are used for expansion cards that do no require the same amount of data transfer that a graphics card requires. You will usually find components such as tv tuners, network cards and sound cards make use of the PCI Express 1x slot. You will also notice the difference in size between the 1x and the 16x slots. The PCI Express 1x slot is noticeably smaller and easy to spot.4 - Chipset - North Bridge (with heatsink)The Motherboards chipset can be described as what sets it apart from other boards in its category. Different chipsets contain different features and components. A chipset is a number of integrated circuits built onto the board to provide specific functions e.g. one part of the chipset may be an onboard component such as a modem or sound chip. Other parts may be used to control the CPU functions. Most chipsets are designed to work with only one "class" of CPU although now many older chipsets support more than one type of CPU such as socket 7 which supports the Pentium, Cyrix 686, Cyrix MII, AMD K6 and K6-2. There are certain restrictions though to what type of processor a chipset can handle because of the logic that the CPU uses to access the memory and its cache etc. Since these chips are working harder with each generation, motherboard manufacturers have started to put heatsinks and active coolers (fans) on the main parts of the chipset to disperse some of the heat.5 and 8 - ATX Power connectorThe standard ATX power connector, the cable for this will be coming from the PSU, a clip is normally provided to make sure you get them in the correct order. As a tip, don't try to push too hard if its stuck, check to see that it is in the correct way, I have seen plenty of power connectors where the pins have pushed out some of the connectors, these can be difficult to get back into place, so its best to be careful.6 - CPU (Central Processing Unit) socketAll the CPU "sockets look very similar, however they are different in the way they have different amount of pins and in different layouts. There are currently two major CPU socket types PGA and LGA. PGA or Pin Grad Array uses a system of pins on the CPU and holes on the socket to line up and hold a CPU in place. The introduction of the ZIF (Zero Insertion Force) socket for PGA types allowed the CPU's to be lined up without any pressure on the CPU until a level is pulled down. LGA or Land Grid Array uses a system of gold plated copper pads that make contact with the motherboard. It is very important to read your motherboard manual to discover what types of CPU's you motherboard supports as most motherboards are aimed at a specific type of CPU.7 - DIMM (Double Inline Memory Module) slotsDIMM's are by far and away the most used memory types in today's computers. They vary in speeds and standards however and they need to match up to what your motherboard has been designed to take. The four standards of DIMM's being used at the moment are SDR (Single Data Rate), DDR (Double Data Rate), DDR2 and DDR3. The speeds of memory can vary between 66Mhz to 1600Mhz.Get great Value on Memory Upgrades at SavaStore Click Here9 - Motherboard controlsNot available on all motherboards, but some allow direct control of the motherboard via simple buttons. Power switch, error checking, CMOS clearing, passwords and more features can be accessed directly on the motherboard on some models.10 - Chipset - South BridgeWhen we talk about chipsets you mainly only ever hear about the North bridge. Even those into PC technology have a hard time naming the south bridges without looking them up. Names like Nforce 2 and KT600 are North bridges. The South Bridge does an important job as well. It handles things like the PCI bus, onboard Network and sound chips as well as the IDE and S-ATA buses.11 - Serial ATA ConnectorSerial ATA or more commonly seen as S-ATA is a new way of connecting your Hard Drives to your PC. S-ATA drives have the capability of being faster than the IDE counterparts and also have smaller thinner cables which help with the airflow of the system. S-ATA hard disks are fast becoming the norm for hard drive technology. Current motherboards feature both IDE and S-ATA connectors to facilitate all types of storage hardware.12 - USB 2.0 headerAs well as having USB ports on the rear of the motherboard, motherboard manufacturers often add a couple of USB headers so you can connect optional cables for extra USB ports. These cables are often supplied and you only need to add them on if you need the extra connectivity. USB 2.0 replaced USB 1.1 as a much faster solution. It is backwards compatible meaning all USB 1.1 devices will work in these new USB 2.0 ports.13 - Motherboard BatteryThe battery gives the board a small amount of power in order to store some vital data on your machine when the power is off. Data stored is that like the time and date so you don't have to reset them every time you boot the machine up. Motherboard batteries are usually long lasting Lithium batteries. Removing this can reset all the data on your machine including the BIOS settings, however not replacing this correctly can lead to irreparable damage to the motherboard. Only remove the battery if it is dead or if you can't have access any other way to resetting the data on your machine by use of the clear CMOS jumper or something similar.14 - PCI (Peripheral Component Interconnect) slotThe PCI bus (not PCI express) is now an older technology and although the PCI slots are still available, they have decreased in number and are being replaced by the PCI Express 1x slots. Its unlikely that you will get a motherboard without a PCI slot at the moment due to the fact that a lot of components still use the standard PCI slot. It would be awkward to upgrade to a system without PCI slots as it may mean upgrading more components than you would like to,15 - Floppy Drive ConnectorMore simple than the IDE connector you only have to remember to get the red line to pin 1 of the connector and the red line to pin 1 on the floppy drive, This port is only to be used with floppy drives. You may not have a floppy controller on your motherboard as its slowly being phased out as more people are using writable CD's and DVDs to transfer data, to store data and to use as boot up discs.16 - IDE connector Not on DiagramThe connector to which you will insert an IDE cable (supplied with motherboard) IDE cables connect devices such as hard disks, CD Drives and DVD Drives. The current 4 standards of IDE devices are ATA 33/66/100 and 133. the numbers specify the amount of data in Mb/s in a max burst situation. In reality there is not much chance of getting a sustain data rate of this magnitude. Both the connectors and devices are backwards compatible with each other, however they will only run at the slowest rated speed between them. All IDE cables will come with a red line down one side, this red line is to show which way it should be plugged in. The red line should always connect to pin one of the IDE port. Checking your motherboard documentation should show you which end is pin one. In some cases it will be written on the board itself.In the case of ATA 66/100/133 there is a certain order that you plug devices in, the cable is colour coded to help you get them in the correct order.The Blue connector should be connected to the system boardThe Black connector should be connected to the master deviceThe Grey Connector should be connected to the slave device17 - BIOS (Basic Input Output System) Chip - Not onDiagramThe BIOS holds the most important data for your machine, if configured incorrectly it could cause your computer not to boot correctly or not at all. The BIOS also informs the PC what the motherboard supports in terms off CPU etc. This is why when a new CPU is introduced that physically fits into a slot or socket you may need a BIOS update to support it. The main reason for this is that different CPU's use different logics and methods and so the BIOS has to understand certain instructions from the CPU to recognise it.
