Hyper-threading\nHyper-threading, officially called Hyper-Threading Technology (HTT), is Intel's trademark for their implementation of the simultaneous multithreading technology on the Pentium 4 microarchitecture. It is basically a more advanced form of Super-threading that first debuted on the Intel Xeon processors and was later added to Pentium 4 processors. The technology improves processor performance under certain workloads by providing useful work for execution units that would otherwise be idle, for example during a cache miss.\n\nMore information - \nhttp://en.wikipedia.org/wiki/Hyper-threading\n\nDual-Core Or Multi-Core\nA multi-core microprocessor is one which combines two or more independent processors into a single package, often a single integrated circuit (IC). A dual-core device contains only two independent microprocessors. In general, multi-core microprocessors allow a computing device to exhibit some form of thread-level parallelism (TLP) without including multiple microprocessors in separate physical packages. This form of TLP is often known as chip-level multiprocessing, or CMP.\n\nThere is some discrepancy in the semantics by which the terms "multi-core" and "dual-core" are defined. Most commonly they are used to refer to some sort of central processing unit (CPU), but are sometimes also applied to DSPs and SoCs. Additionally, some use these terms only refer to multi-core microprocessors that are manufactured on the same integrated circuit die. These persons generally prefer to refer to separate microprocessor dies in the same package by another name, such as "multi-chip module", "double core", or even "twin core". This article uses both the terms "multi-core" and "dual-core" to reference microelectronic CPUs manufactured on the same integrated circuit, unless otherwise noted.\n\nMore information - http://en.wikipedia.org/wiki/Dual-core\n\n64-bit\nIn computer architecture, 64-bit is an adjective used to describe integers, memory addresses or other data units that are at most 64 bits (8 octets) wide, or to describe CPU and ALU architectures based on registers, address buses, or data buses of that size.\n\nAs of 2004, 64-bit CPUs are common in servers, and have recently been introduced to the (previously 32-bit) mainstream personal computer arena in the form of the AMD64, EM64T, and PowerPC 970 (or "G5") processor architectures.\n\nAlthough a CPU may be 64-bit internally, its external data bus or address bus may have a different size, either larger or smaller, and the term is often used to describe the size of these buses as well. For instance, many current machines with 32-bit processors use 64-bit buses (e.g. the original Pentium and later CPUs), and may occasionally be referred to as "64-bit" for this reason. The term may also refer to the size of an instruction in the computer's instruction set or to any other item of data (e.g. 64-bit double-precision floating-point quantities are common). Without further qualification, however, a computer architecture described as "64-bit" generally has integer registers that are 64 bits wide and thus directly supports dealing both internally and externally with 64-bit "chunks" of integer data.\n\nMore information - http://en.wikipedia.org/wiki/64-bit

It runs at 3.06 GHz , it could run two threads of execution\ninstructions from the same process

D = Dual Core. Two cores are better than one and the price is right. It's like having two CPU's instead of one to a degree, it's not totally the same as there is the I/O bottleneck.

Some of that is old stuff.\n\nSTAT II is the up and coming thing instead of ATA 100\n\nWhat is the RAM?  DDRII?  That's new, also.  DDR is old and SIMM is ancient!\n\nThe CPU is 64 bit ready, correct?

32 bit and there's only one processor! (with dual core)

There are several classes and sub classes, but for the most part:\n\n286\n386\n486\npentium\n--pentium pro\nP2\n--Celeron, crippled P2 (or was it P3)\nP3\nCeleron becoms its own, less multimedia stuff in it\n(linux servers love'em)\nP4\n\nP4HT (Hyper Threading) apears to be 2 CPU's in one. but still one core)\n\nP4DC (Dual Core, acts as 2 cpus, becouse there is 2 coes on one physical chip)\n\nWithin those, there are many variations, for differnt applications such as servers, also there are differnt cache sizes for every one as well.\n\nSo if Joe has a P4-2GHz for $500 and Jane has a P4-2GHz for $100, well janes is going to kick joes butt, could be more cache, 1 meg etc..\n\nJust my 2Cents

This is not a choice.\nDual core are (usually) capable of 64 bit.\nIt's like asking "What's better, a Rottweiler or a dog?"\n///

Dual core means there are physically two processors together in one footprint.\n\nHyperthreading means that there's only one real processor and it is split into two processors virtually (via software/firmware simulation).\n\nSo, in answer to your question, having two real processors (Dual Core) is better than having two virtual processors (Hyperthreading).  But, that may also depend on the speed of the processors, RAM, HD space, etc... so, you'll want to look into that part of it before buying.

Hyper-Threading.\nit's like a processor pretending to be 2.\ngenerally (depending on the application)\nit actually slows down performance\n\ni forgot the specifics on it, but it queus up instructions and splits them between two arithmetic logic units (ALUs)\nand other parts....\n\ndont take the second part of my answer word-for-word. i really don't remember the specifics

64bit processors have the ability to run 64 bit operating systems(i.e. windows xp pro 64bit), and use 64 bit applications. 64 bit allows more system memory, among other things. Yeah the fx55 amd is over $1000 and is "only" 2.6ghz. But it is the fastest cpu in existance right now, so that "justifies" it's price. It beats an intel 3.8ghz. A 64bit 1.8ghz cpu, which is equivalent to a p4 3ghz is about $150. Not that expensive, and way cheaper than intel's new 64 bit chips.

AMD 64 bit dual core. The older CPUs are 32 bit so this is twice fast.It runs at higher bus speeds and blows the doors of of anything that Intel makes. Also it allows you to run alot faster RAM Memory sticks and with the board below as long as you run all the same brand of sticks it will run them in the dual channel mode which is twice as fast.With 4 slots for the memory your talking being able to build a kick butt computer. I think I paid maybe 200 buck for the board and CPU. Intel makes a 64 bit but unless all your drivers are made to run with a 64 bit you have nothing but major problems stuff wont work (cd, dvd,video,sound,and so on) get the picture. Amd 64 on the on the other hand is compatiable with either 32 or 64. Also it is verrrry able to be overclocked (speed up the bus speed) I have a AMD 3200+ 64 bit it is a 2 gig CPU. I have it on a GIGABYTE GA-K8NSC-939 motherboard, the 939 is how many pins are on the bottom of the CPU the higher the better and 939 is the highest right now. By pressing the delete button at start up it will take me into the bios settings setup so if you want to I can change them. One of the nice things with this board is the it allows to change the bus speeds and AGP (accelerated graphics port settings) or basicly the port that your video card is plugged into this nice because you can also speed it up to. Nice for gaming or watching videos. I have turned up the bus speed set on mine without having to turn up the voltage (which might cause the CPU to overheat if set to high) the AMD will handle a voltage up to 4.9 volts right now mine is around 3 volts get the picture AMD kicks a+s. I have my CPU overclocked to 2.41 gigs. So basicly my 2 gig CPU is now a 2.41 gig CPU. Ive had it running like this for a year without ever having any problems at all, infact this bad boy boots up in about 20seconds,not bad!!! Any computer tech will tell you to GO WITH THE AMD they out bench mark and totaly out perform any thing Intel makes!!!!!! Intel makes a quad-core but basicly AMD doesnt care because their dual still blows Intels quad away. Check the bench marks for yourself.\n\nTuea - You have it it on the head!!!!!!!!!!\n\nZeus

Problem with core processors is very little applications take advantage of the multi cores. Yes, it is faster then the regular core duo. I don't remember the speeds check out http://tomshardware.com for reviews perhaps they did one on this.

I will tell about threads in simple language. Do you browse the web and listen to your favorite songs at the samte time?? Well, then the browser is running as one thread and the music player as other thread. Both work on their own and not interfering each other. Got it??\n\nYou must have heard about the HT technology - Intel's latest processor has it. This is the new improvement in hardware that makes it possible to have threading at processor level.. \n\nHope this gave u some info. If u need more details, let me know.. :)

A pentium 4 is a single core single threaded processor. This is the normal kind of processors we have been seeing for a while now. \nA Dual core actually contains two (nearly) independent processors in a die i.e. it is as good having two processors on one chip. These chips typically have a lower frequency rating. But they are designed to provide higher throughput. \nHT stands for Hyper Threaded. In technical jargon called Multi-threaded, this processor gives a notion of two processors even the most of the individual components of the processor are shared. (The Functional Units are shared. My understanding is that Pentium 4HT implements coarse grained multi-threading, so the pipeline is the same but the register file will be duplicated.)\n\nWhich one is better depends on the kind of application you are looking at.

Core 2 Duo is far superior.  The Pentium 4, though it does have the capability of hyperthreading, it is still just a single core 32 bit processor.  The Core two duo has two 64 bit processing engines, so it can process more instructions at one time.

Yep absolutely nothing.\nNow if you want the difference between an AMD XP 2800+ and a AMD Athlon 64 2800+. This will be a big difference.\nAMD 64 is newer technology, it's faster and needs different computer equipment.
