A Honest Computer CPU Buying Guide

Posted by on 4 September, 2015 in CPU

Should you wish to either build a desktop PC from scratch or even upgrade your current one, the most critical component that you should consider is the kind of computer CPU you can obtain. This can be accurately regarded to be the very “brain” of your PC. Not only does it determine just what you can do, but how quickly and efficiently you can do it. The CPU is also called the processor, and it controls virtually everything from working with productivity tools to playing a game. With a few exclusions, the exact power you can obtain from a processor is directly proportional to the price you are willing to foot. To this end, the following is a computer CPU buying guide that can assist you in making the right choice.

Price

PC building and even upgrading, like previously pointed out, starts at what exactly you intend to use it. Given, it is very possible to execute similar tasks with a $100 processor as you would with a $1000 one. However, the major difference lies in just how well you will be able to perform the particular tasks you have in mind. Therefore, determining the exact amount that you want to spend should be the first thing you should take into account. Typically, high priced CPUs tend to be much quicker and more efficient. So it is very important to bear this in mind.

Cores

The exact number of cores a processor possesses is undoubtedly the most crucial factor you need to contemplate on. Nowadays almost all CPUs integrate from two to six cores. Should you be planning to make use of your computer for intensive tasks such as video or photo editing, you will certainly benefit from a processor with more cores. At the same time, it is important to take note of the fact that it is possible to obtain a CPU that comes with just a single core. But it is highly advisable to bypass such products. Dual core processors are very commonplace and relatively inexpensive, and it can be a wise decision to settle for such products.

Clock speed

Back in the bygone era where all processors featured a single core, clock speed or operating frequency was the most critical issue to dwell on when attempting to buy these components. Most especially when it came to deciding just how quick and efficient a CPU could be. Currently the number of cores a computer CPU has effectively replaced the dominance of clock speed, but the latter is still an essential factor that you should think about.

Clock speed is gauged in gigahertz (GHz) or quite simply the number of billion times per minute a CPU’s clock pulses into the microprocessor. With this in mind it is safe to think that a 3GHz processor is definitely much faster than a 2 GHz rated one. Nevertheless, this assumption can be erroneous in certain particular circumstances. For instance, it is well known that in multiple core CPUs, the number of pulses are usually stacked. So a 4 core, 3 GHz processor is in an excellent position of beating a 2 core, 3.3 GHz CPU. Hope this computer CPU buying guide has been insightful.

Types of Computer Hard Drives

Sometimes you may switch on your computer and get the message “imminent Hard disk failure”. You may also drop your computer and when you try to switch it on, you only get a blank screen or I does not light at all. These are just the few things that will indicate to you that you do need a new computer hard drive. When your hard drive crashes, they likelihood of you loosing all you documents and photos is up to 90%. For a computer user, this can be among the most frustrating things to happen.

A computer hard drive stores all the software installed in the computer and this is the reason why it will not come to life. The windows application used by your computer is itself a software. It is a form of permanent storage for your computer unlike the RAM, which is much more temporary. This means that even when the computer is turned off, your data is safe. The two types of hard disks include: Solid state drives and Hard disk drives.

Hard disk drives

These are the most dominant and have been a traditional type of hard disk. They have been used since the early days when the computers began being used. They consist of a rigid disc that is made of non- magnetic materials which have been coated with a thin layer of material that is most often magnetic. The data in these computer hard drives in stored through magnetizing this thin film. The disk usually moves at high speed and the magnetic head that is mounted on the moving arm is used to read and write data. Normal hard disk drives operate at a speed of 7, 200 rotations per minute and this is usually specified on the hard disk itself.

Because of this movement, hard disks are generally very noisy and have a humming sound although manufacturers have really tried to reduce this noise in modern hard drives. They are very robust and can be used for many years without causing the users any issues. Their most common issue that causes them to crash is the head crash that occurs when the magnetic head scratches the magnetic film. This problem normally occurs as a result of physical stress mostly when the computer drops while it’s still on. When the magnetic film is damaged, it can cause loss of data making it a great idea to have a backed up copy of all your files.

Solid- state drive

They are relatively newer to the market and mostly for high- end expensive hard drives. The use flash memory often used in memory cards and flash drives. Because they have no moving parts, they are rarely damaged by physical shock. They are mostly not preferred because they are very expensive. For example, a 110Gb hard drive may cost about $80, an SSD of the same capacity could cost as much as $150. However, with many companies coming up, their price is reducing gradually.

They are quick in reading data and are not as prone to damage as hard drives.
