It must have been difficult for Intel to watch AMD's Athlon 64 and then the Athlon 64 X2 and FX pretty much take over the performance PC market, putting the once-untouchable chip giant into a position where its only competitive response was to cut prices. Those were dark days indeed. But now, with the release of the long-awaited codename "Conroe" -- the Core 2 Duo and Core 2 Extreme processors -- Intel looks set to start a new age of desktop domination.
Most onlookers expected Intel to take back the performance crown from AMD, but few anticipated the sheer magnitude of this victory, or the nearly flawless style with which Intel performed it. And the Core 2 Duo is just the first strike in this battle, as Intel is also planning preemptive Pentium D price drops and has revamped its single-core Pentium 4 and Celeron D lines as well.
The Conroe excels in three areas, which add up to the very definition of what a current buyer expects from a top-end desktop CPU. These factors are price, performance, and power requirements, and the 65-nanometer-process Core 2 Duo and Extreme have surpassed their AMD counterparts in each, completing the same type of triple play that AMD had turned on the Pentium 4 and Pentium D.
The question of who's got the best performance is not even up for debate: The 2.93GHz Core 2 Extreme X6800 is the fastest desktop processor on the planet, and the 2.66GHz Core 2 Duo E6700 is not far behind. Even the next-step-down 2.4GHz Core 2 Duo E6600 is an outstanding desktop performer that can outpace AMD's flagship Athlon 64 FX-62 in most tests.
Power and cooling requirements are also extremely low -- the Core 2 Duo line offers the lowest power draw of any dual-core processor, with the Core 2 Duo Extreme not far off. Prices are also extremely competitive. In fact, it's amazing that for such a competitive price , the Core 2 Duo E6600 can outrun AMD's entire desktop lineup. The lower-end Core 2 Duo E6300 and E6400 models are even more affordable, although their 2MB instead of 4MB of Level 2 cache mean their relative performance isn't as high.
Intel has accomplished this via a drastic shift away from the Pentium's NetBurst technology. Conroe's next-generation core performs more instructions per clock cycle (IPC), rather than having a longer and potentially less efficient pipeline that can be clocked into the stratosphere. Core 2 processors' 2MB or 4MB of 256-bit L2 cache feature what Intel calls Advanced Smart Cache, dynamically shared between the two cores for maximum efficiency rather than chaining half the cache to each core.
With IPC levels exceeding those of AMD plus clock speeds up to 2.93GHz and a 1066MHz front-side bus, Intel has moved well ahead in the performance game despite sticking with traditional CPU and chipset architecture rather than AMD's on-chip-memory-controller approach.
The Conroe design also reflects a need to keep power requirements and heat production down via various power-saving technologies. Since the basic architecture will be shared through all of Intel's processor lines (except the Itanium), including upcoming mobile CPUs, this translates into very power-efficient processing.
The Core 2 Duo and Extreme processors may offer industry-leading performance, but Intel's SpeedStep technology ensures that the chips can ramp down the multiplier and reduce clock speed to conserve battery power and/or lower core heat levels.
Moreover, new Intelligent Power Capability can go beyond slowing the CPU as a whole to turning various core functions on and off as required. These power-saving techniques don't get in the way of outright performance, as the Conroe instantly jumps back to top speed when required.
Through the use of technical expertise obtained through advanced CPU server technology and exprertise Intel has leapfrogged once again to a combination of power , low energy use and heat production and reliability especially since with advances in CPU speed can disabling and damaging hear.
The Core 2 Duo CPUs should be a major consideration in your next high end computer purchase.

AMD Versus Intel CPU War
If you are in the market to purchase a computer there are many options in existence. You can purchase a Hewlett Packard, Gateway, IBM, or a custom built system. But there is one thing that all of these computers will utilize and that is a CPU (central processing unit). The CPU is responsible for interpreting and executing instructions for the motherboard. CPU's are key to the functioning of your new computer. CPU's from Intel and AMD power virtually every personal computer that you can purchase today.
The argument over an AMD CPU versus an Intel CPU and which has a higher functionality is currently raging. Simply two years ago this was not even a question. Anyone would tell you that the Intel CPU won the speed and complex algorithm war with AMD CPU's without question. Fast-forward to today and Intel is now playing catch-up to the latest in AMD technologies.
Intel played marketing games with their CPU's pricing them high and touting the functionality that they posses as cutting edge. AMD started out as the cheap alternative CPU manufacturer for computer brands such as e-Machines and low-end Compaqs. From the beginning, AMD CPU's were fighting an uphill battle to catch up with the technology in the Intel CPU. As the years have progressed, AMD has progressed.
AMD now clearly leads in the consumer pricing wars. AMD CPU equipped machines with similar performance specifications will cost you hundreds of dollars less than equivalent Intel CPU based machines. This cost differential is now enough to push many Intel CPU customers to the upstart AMD CPU equipped machines.
If performance is the main concern over price, the AMD CPU line was the first to include 64 bit technology. In 2003 AMD pushed the first 64 bit CPU to market. It was unstable and unreliable at first. But the underlying architecture was sound. The AMD 64 bit CPU was soon running stable and fast. The performance of this AMD CPU caught the Intel CPU team off guard.
Intel had to rush to market their EMT64 CPU to compete with this upstart challenge from AMD. The next item on the board was dual CPU power. Again, AMD one-upped the Intel CPU rule.
AMD CPU's have the information transfer on a dual chip machine flowing through the chips. The Intel dual CPU has a bridge to the motherboard where the information that is being processed by the dual CPU's flows for splitting.
The internal data flow in the AMD CPU's allows them to function with lower heat generation than the dual core Intel CPU's. As a consumer this lower heat generation allows the AMD CPU to last longer than the Intel CPU.
If you are energy conscious, then the AMD CPU will be for you as well. The AMD CPU equipped motherboard will function with approximately 275 watts of power. Compare that to a similarly equipped Intel processor at 400 watts of power, and you have major energy savings by going to the AMD CPU.
So where do the Intel CPU's win out over the AMD CPU's? The Intel CPU's are able to function faster with single programs. So, if you are going to play one game and only that game on your machine, the Intel CPU equipped machine can pull and analyze the data faster. However add in chat and e-mail running in the background and the AMD CPU machine catches up.
All in all, the CPU processor war that is currently waging between AMD and Intel is great for the consumer. Each company is in the middle of a CPU processor one-upmanship and both are looking to gain market share.

Why Upgrade To Corsair DDR2 RAM?
New technology is being introduced every day it seems. Computers are finally getting more stable and they continue to get faster. In this article we I will be talking about some of the new advances in RAM, specifically the new Corsair DDR2 Ram and what it can do for your computer.
First, for the newbies, a definition of what RAM is; According to Princeton University, random-access memory is the most common computer memory that can be used by programs to perform necessary tasks while the computer is on. It is an integrated circuit memory chip allowing information to be stored or accessed in any order with all storage locations being equally accessible
When you check your computer’s resources, you are checking the amount of RAM that is still available to run programs on your computer. Every program that runs in the background is using a little or a lot of your available RAM. All of those icons in your system tray down on the right are programs that are running and there are some necessary processes running that are not displayed as icons that are also using some of your RAM.
For a long time conventional wisdom showed us that processor speeds were outpacing memory, which didn’t allow the processor to work at its own top speed. Now due to Corsair DDR2 memory, the situation has reversed. You now need to be sure your motherboard can allow this amount of faster, more effective ram to work up to its maximum potential.
This is good news for computer users. It will allow the makers of processors and motherboards to improve upon their hardware, giving us truly faster computing.
A quote from a Corsair press release states, “Corsair® Memory, the worldwide leader in design and manufacture of high performance memory, today unveiled the world’s first DDR2-800 2GB kit rated at true low latency of CL3. The latest addition to the award-winning XMS. Family of products, TWIN2X2048-6400C3 delivers unparalleled memory performance at 800MHz and supports the industry’s lowest latencies of 3-4-3-9 in this speed grade. Featuring Enhanced Performance Profiles (EPP), a new open memory standard jointly development by Corsair and NVIDIA®, the users can take advantage of the added memory performance characteristics and capabilities when used with an EPP-capable motherboard.”
Corsair has succeeded in finally addressing the problems of latency as processor speed continues to increase. By doing so Corsair DDR2 RAM will allow manufacturers to continue building faster processors while Corsair starts working on DDR3, whatever that might be.
How fast is fast enough? That’s a question I get asked often. The average computer user only uses a small portion of the computing power at their fingertips. However, many companies, government agencies, and researchers use all of the potential built into their computers processors and ram.
There are many important tasks that computers perform that affect our daily lives. Air Traffic Control, Defense Systems, Health and Medical Research, Accounting, the Stock Market, and even traffic lights and signals at railroad crossings. The need for faster, more reliable, and more powerful computers is crucial to each and every one of us. Thanks to Corsair, we are moving forward.

How To Add A USB 2.0 Hub To Your Computer
Digital and video Cameras, scanners, mp3 players, and just about every other electronic device are designed to be connected to your computer.
And all new computers make it simple to connect these devices with the use of the USB or Universal Serial Bus port. But with the many devices you may have,you can still run short of these ports.
If you find your computer using all of its USB ports, you can get your hands on a USB Hub. This hub contains several usb ports. So rather than unplugging one device to plug in another, a usb hub allows you to connect multiple devices.
To setup a usb hub on your computer you need to be sure your system allow you to connect the hub. If your computer was made before 1997 it most likely won't support a USB.
Check your computer to see if there is a usb port available. http://www.ultimatepcrepair.com/photos.html have photos showing what USB ports look like and where they should be found in any computer.
You should consider the reason you want to purchase a USB hub. This will help in deciding the type of usb hub you want to purchase. And research the device you want to connect, as not all devices can be connected to USB hubs.
The two types of USB hubs are the Self Powered which draws power from an external power supply and the bus powered hub which is inserted in an expansion slot and draws power from the motherboard.
Some devices that use large amounts of power work poorly with bus powered hubs. A scanner for example, will wotk much better connected to a self powered USB hub.
When connecting a device to the USB hub, see what version of usb it may be. USB 1.0 was the first version released and today the fast version is the usb 2.0 All USB 2.0 hubs are backward compatible. This allows them to run the slower USB 1.0 devices.
The price of a hub 2.0 hub varies from about $25.00 to $65.00 and comes in several brands. The price depends on the number of ports you want on the hub.
INSTALLING YOUR NEW USB HUB
Its always a good practice to backup your files before you work in your computer.Remove the hub from its packing and carefully inspect it for damaged and be sure all components are present. Stop and carefully read the hub manual for instructions such as turn the computer off first or that you must install the software before connecting the hub to the computer.
If you have a powered hub, plug the power cord in an outlet and connect the usb cable from the usb hub into an open USB port. With the hub connected place the cdrom that come with the hub and install the software onto the hard drive.
Set the USB hub in a location where you can easily connect your scanner,modem,or other devices. Remember that your computer only runs at the highest usb speed.If your hub is a USB 2.0 but your computer only supports USB 1.0 then the 1.0 connection will be your max speed.
If your USB hub is self powered,install the card in an empty expansion slot by removing the system unit cover, removing the retaining screw and cover from the slot, firmly slide the card in the slot, and use the retaining screw to secure it to the motherboard.
Start your computer and your operating system should recognize the new device. Install any software that came with the hub.You may need to install a device driver to allow the computer to communicate with the hub.
Its that easy and why not make it something fun to do. Learn as you go and be in the state of mind to enjoy your task. You will look forward to perform other tasks in the same state of mind.
