hiii frnz....
today there r no of processors in the comp industry...i myself find the diff btw each of them very confusing,so in this post i hv tried to mark the diff btw above mentioned processors...
comments are most welcome...
Core 2 Duo is a brand name by Intel - Dual-Core is a generic description meaning two separate physical cores in one chip package.
Dual core is simply a generic term referring to any processor package with two physical CPUs in one. The Pentium D, Core Duo, Core 2 Duo and Athlon X2 are all current CPUs that have dual cores in one package.
The Pentium D is simply two Pentium 4 Prescott cpus inefficiently paired together and ran as dual core.
The Core Duo is Intel's first generation dual core processor based upon the Pentium M (a Pentium III-4 hybrid) made mostly for laptops (though a few motherboard manufacturers have released desktop boards supporting the Core Duo CPU), and is much more efficiently than Pentium D.
The Core 2 Duo is Intel's second generation (hence, Core 2) processor made for desktops and laptops designed from the ground up to be fast while not consuming nearly as much power as previous CPUs.
Note - Intel has dropped the Pentium name in favor of the Core architecture as Intel is restructuring and refocusing it's efforts to become number one again (and are doing a fine job, might I add).
The AMD Athlon X2 CPUs have two revisions, the first one is essentially very similiar to the Pentium Ds in that they are simply two Athlon 64 chips fused together, making power requirements quite steep (around 89 watts). The second revision is made more efficiently, like the Core Duos, with much less power consumption (around 65 watts).
There are, of course, other differences, but that is the gist of dual cores as it relates to Intel and AMD.
____________
Note that there are different Core 2 Duos, too. There is an extreme one, too, but that just may mean it's hyperthreadable and not too much of an advantage (or possibly a disadvantage) in Seticrunching.
Actually, the Core 2 Extremes do not have HT and it's unsure whether Intel will keep using this or not.
The only difference between a Core 2 Duo and a Core 2 Extreme is that the Core 2 Duo's have a locked multiplier and the Core 2 Extreme's have a range of multipliers, which seems to be the first time Intel is encouraging overclocking since the original Pentium Classic days.
The new Conroe/Core duo ect have got me a bit confused. Can someone tell me which would be faster. Comparing to almost identically priced chips.
both about £110;
Pentium D 945 -- (3.4Ghz FSB;800 2Mb)
Core Duo E6300 -- (1.86Ghz FSB;1066 2Mb)
How do these compare to each other?
What speed chip (Core Duo) would you need to get to get similar or better performance (not just for seti ect) than standard Pentium D's at about 3-3.4Ghz? I know you can get faster and cheaper D's but then their too slow or too expensive really.
According to user reports, a Core 2 Duo E6600 (2.66GHz, 1066MHz FSB) is much faster than a Pentium D running at about 3.4GHz due to it's ability to process more Instructions Per Second (IPC) and it's shorter pipeline (doesn't take as many stages to decode the same instruction) and it's more efficient L2 cache. Not to mention it consumes LOTS less power than a Pentium D at a higher clock speed.
Comparitively, the E6300 should be about as fast as a Pentium D 3GHz (roughly).
Basically, if you're looking to build a new system and have decent budget, go for the Core 2 Duo (Conroe). You'll be happy that you did.

11] Keep your Dektop clean with unwanted icons
12] Use Intel Application Accelerator to speed up your disk access,
13] Memory management (at least 512MB RAM Required). This allow XP to keep data in Memory instead of paging section of RAM.Go to->Start->Run->regedit->HKEY_LOCAL_MACHINE->SYSTEM->CurrentControlSet->Control->Session Manager->Memory Management->Double click it->DisablePageingExecutive->Double Clik it->Set value to 1.
14] Disable Yahoo Messenger, Google Talk, and other unwanted programs from startup. (You can use registry editior to do this.). Because they do not appear in normal Startup Option.
15] Disable indexing files service (only if you do not use search option regularly). To do this follow the following steps.Go to My Computer->Select the drive for which you want to disable the indexing service->Properties->Unselect 'Allow Indexing Service'->Ok.
16] For Windows XP, You must use NTFS partition. FAT partition is less supportive for Windows XP.
17] In BIOS, Select first booting device as your HDD.
18] Setting Priority High for a particular program.Open Task Manager->Processes->Select the desired Program->Right Click->Set Priority->High->Ok.This Priority set if for current session. Once you restart your system then its priority will again be Normal.
19] Keep deleting your Temporary Internet Files in regular intervals.Go to Windows Drive (c: or d:)->Select the User->Local Settings->Temporary Internet Files
20] Empty your browser's cache in regular intervals.

Computer hardware cleaning...useful tips
GENERAL CLEANING TIPS
Below is a listing of general tips that should be taken when cleaning any of the components or peripherals of a computer as well as tips to help keep a computer clean.
1. Never spray or squirt any type of liquid onto any computer component. If a spray is needed, spray the liquid onto a cloth and then use that cloth to rub down the component.
2. Users can use a vacuum to suck up dirt, dust, or hair around their computer on the outside case and on their keyboards. However, do not use a vacuum for the inside of your computer as it generates a lot of static electricity that can damage the internal components of your computer. If you need to use a vacuum to clean the inside of your computer, use a portable battery powered vacuum designed to do this job.
3. When cleaning a component and/or the computer, turn it off before cleaning.
4. Never get any component inside the computer or any other circuit board damp or wet.
5. Be cautious when using any type of cleaning solvents; some individuals may have allergic reactions to chemicals in cleaning solvents and some solvents can even damage the case. Try to always use water or a highly diluted solvent.
6. When cleaning, be careful not to accidentally adjust any knobs or controls. In addition, when cleaning the back of the computer, if anything is plugged in, make sure not to disconnect any of the plugs.
7. When cleaning fans, especially the smaller fans within a portable computer or laptop it's suggested that you either hold the fan or place something in-between the fan blades to prevent it from spinning. Spraying compressed air into a fan or cleaning a fan with a vacuum may cause damage to some fans.
8. Never eat or drink around the computer.
9. Limit smoking around the computer.
CD-ROM CLEANING
Why? A dirty CD-ROM drive or other disc drive can cause read errors with CD discs. These read errors could cause software installation issues or issues while running the program.
Procedure: To clean the CD-ROM drive we recommend purchasing a CD-ROM cleaner from your local retailer such as a local Radio Shack. Using a CD-ROM cleaner should sufficiently clean the CD-ROM laser from dust, dirt, and hair.
Also see our below CD cleaning recommendation for steps on cleaning each of your CDs.
Additional help: CD-ROM Page
CD CLEANING
Why? Dirty CDs can cause read errors and/or cause CDs to not work at all.
Procedure: Cleaning CDs should be done with a CD cleaning kit but can also be done with a normal clean cotton cloth or shirt. When doing this with a clean cotton cloth or shirt, wipe against the tracks, starting from the middle of the CD and wiping towards the outer side of the CD. Never wipe with the tracks; doing so may put more scratches on the CD.
It is recommended when cleaning a CD that water is used. However, if the substance on a CD cannot be removed using water, pure alcohol can also be used.
HARD DISK DRIVE CLEANING
Why? While hard drives cannot be cleaned physically, they can be cleaned with various utilities on the computer to help it run fast and more efficiently. Utilizing these utilities will prevent the hard drive from slowing down.
Procedure: Refer to our basic troubleshooting section for your operating system for steps that can be done to help improve the performance of your computer.
PALM PILOT CLEANING
Why? Dirty touch screens can cause difficult navigation.
Procedure: To clean the Palm Pilot Screen, use a soft cloth moistened with rubbing alcohol and rub the screen and the casing of the palm pilot. It is not recommended to use glass cleaner as it could damage plastics over time
