What Your Quad Core Computer Can Do For You?

Quad core computer contains four processors and can be considered a part of multi core processors family. There is hardly any doubt that the performance of quad core computer is much faster than that of dual core computers. However, the performance of quad core computer depends upon the type of programs that run and the algorithms used in those programs.

There is a popular misconception that the quad core computer runs four times faster than the single processor computers. It does work, but for programs that are designed to perform on quad core computer. The codes written in those programs allow the processor to accomplish four different tasks simultaneously. Games such as Gears of War or Crysis which require multiple tasks like audio, physics benefit or AI to run simultaneously can be played through the multi-threading processors of quad core computer.

Performance wise quad core computers are faster in multitasking and parallel programming. For instance, multiple virtual machines can be run with four processors. Hardware virtualization, high-end video game playing provision, video and photo editing, audio transcoding, data folding, 3D rendering, voice recognition facility, the options are so many to choose from in quad core computers. You can run virtual studio on XP, work on Photoshop projects on core OSX install or do any other programs in lunux distro. You can also run XP virtual machine on top of XP. You will be able to run the maximum amount of virtual machines that ESX 3 is capable of running. However the number of Virtual machines you run depends on the memory space of your quad core computer.

While talking about quad core computers, it is worth discussing about certain models of the quad core family. The Kentsfield is the first quad core desktops range from Intel. Its High performance model was Core 2 Extreme QX6700 and mainstream brand was named as Core 2 Quad Q6600. Currently Intel has brought two other models: the Core 2 Extreme QX6850 and the Core 2 Quad Q6700. Of these two, the Core 2 Quad Q6700 is just a modification from the Core 2 Extreme QX6700 adorned with a locked core multiplier.

Actually the Core 2 Q series processor of Intel is nothing but combination of two completely distinguishable Core 2 Duos packaged into a single-socket CPU. The L1 and L2 caches are different to the two individual Core 2 sets. Front side bus architecture is used to communicate with a unit of external memory controller of the north bridge. The initial Core 2 Q6700 shows an effective 1066MHz FSB clock speed with a bandwidth of 8.5GB/sec and the Core 2 Extreme QX6850 can go up to 1333MHz having bandwidth of about 10.7GB/sec.

Having said about the things that you can do on a quad core computer, the question that is being currently debated on is whether these quad core computers are a real need for this hour. For example, same performance and speed can be achieved with a dual-core CPU of Core 2 E6850 as with the Core 2 Extreme QX6850. So why you any user opt for quad core series which are expensive than the Core 2 computers? It is a fact that for general purpose use, today, Dual core or Core 2 is best economical option. Actually quad core computers were not designed for general users. It is for high end users who want to use complex algorithm programs, run parallel programming, multithreading as well as multitasking simultaneously.

However, with the advent of more complex coding programming, quad core computer is expected to be in demand in near future. In fact, computer manufacturers are positive about a significant growth of quad core computer users with in a year or two.

How To Prevent Your Computer From Slowdowns

Written by oneself on 4:15 AM


by: Subhash Kumar


Prevention of your computer from slowdowns effects the performance of your computer, because if your computer working with proper speed, it definitely increases your efficiency and working speed. These are the guidelines given below which will help to maintain your computers speed:

•Fragmented hard drive is the biggest bottlenecks of all. Disk fragmentation can significantly slow down your machine. A common cause of disk fragmentation is a disk that is too full. You should keep 20 percent to 25 percent of your hard disk space free to minimize file fragmentation and to improve the defragmenter’s ability to defrag the disk. Thus, if a disk is too full, move some files off the drive and restart the defragmenter. Once you defrag (defragment) your hard drive, you may notice an immediate and significant increase in system performance.

•Ensure antivirus software is installed, automatically checking for updates, and automatically scanning all incoming files. If there is a virus associated with a new file it will automatically be repaired or quarantined. New viruses come out daily. Because of this, the anti-virus software needs to be configured to automatically updates it's self.

•When Windows boots up, one of the first things it does is check the Fonts folder and then load all of the fonts present so that they will be accessible from whatever applications you are running. The problem is that all of those fonts eat up resources, and they slow down your system, especially on boot up. To over come this problem open my computer, then double-click the Control Panel icon, and then the Fonts folder. The system will display a list of all of the fonts currently installed on your computer. Double-click any font to see examples of it. If it looks like something you will never use, select and then delete it.

•One often-ignored culprit of system slowdown is the machine’s BIOS settings. Slowdowns may occur if the BIOS settings do not match the optimal machine configuration. Often you can improve machine performance by researching your motherboard’s optimal BIOS settings, which may not be the same as the factory defaults.

There is no centralized database of optimal BIOS settings, but you can employ a search engine such as Google or AllTheWeb and use your motherboard name and BIOS as keywords to find the correct settings.

•Read the terms and conditions before signing up for or downloading anything for free on the Internet. Free downloads like Kazaa (music), games, toolbars, and coupons often come with adware or spyware. The terms and conditions of downloads explain adware will be installed on the persons machine in exchange for the free software, music, pizza or whatever. Of course, few people read these terms and conditions.

•Multitasking was a boon for which we had been waiting for years. Suddenly, we could actually set the computer to a task and that task could continue while we did something else, such as work on a document or browse another Web site. Microprocessors, even today's more powerful ones, can only do so much before they begin to bog down. If you have multiple applications open, especially if they are each working on tasks, overall speed will suffer; the multiple tasks will indeed get processed, but that processing will take place more slowly than if any one of the activities were the only one taking place.

•Modern processors generate a lot of heat. That’s why all processors require some sort of cooling element, typically a fan of some type. When the processor temperature goes over spec, the system can slow down or run erratically.

•Install a hardware firewall to keep hackers out. Hackers have automated tools that are looking for any PC connected to the Internet without a firewall. If you are connected to the Internet but don't have a firewall, hackers (criminals) will be in your PC. Beyond stealing your information they can install programs that can damage or slow your PC down. A hardware firewall to protect all the PCs on the local area network provides the best protection. Recommended hardware firewalls are Linksys, Netgear, and D-link.

•Your computer is a complex system comprising many pieces of hardware and software, all of which must work well together for optimum results. Eliminating the bottlenecks that result in system slowdowns is one major step in that process.

If you follow the above prevention, definitely your computer running better. We suggest doing these things yourself or schedule a computer professional to proactively perform and ensure these preventive maintenance steps are in place and working on a monthly basis. This will prevent computer slowdowns.
