Processor Speeds

The processor speed is the most important thing inside a computer. It is what you want to look out for when purchasing a computer. Processing speed is what makes a computer run faster and is how many commands it can execute a second. The only fault in computer speed is the RAM is extremely slow so its always best to get a very large RAM for a faster computer speed. Computers with slow processors are likely to not last for a few years. Moderately fast processor speeds can last a little while longer, but really fast top of the line processors can go for quite some time before dying and becoming unusable. High processor speeds are not always better. High processor speeds are not always better. You need a balanced and well rounded PC for the processor speed to actually make a significant difference. If you have a 3.2 Ghz processor speed but weak statistics on everything else, then it isn't worth all of the money spent. Having a system with good balance is ideal. If you have a 2.66gHZ processor speed, with 9GB of DDR3 RAM, then your computer is likely to not even utilize all of it. As games and cameras become more advanced however, it will eventually catch up.


A computer core is the main component behind a computer. There can be dual cores, quad cores and even 4 cores in one computer! Each one of these cores contain a cache memory, page file, RAM and all the main components for a computer. You only need one of these to run a computer but obviously more of them means more commands which means a higher processor speed which means that the computer can have an even bigger processor speed.

A dual core processor is one of the newest advancements in computing technology. They were heavily implemented in desktop computers beginning in 2005, allowing computers to process significantly more data than a single core processor can. Dual core processors split the incoming data stream into two pieces, which are calculated simultaneously, leading to a speed increase in processing heavy applications. Each dual core processor has two separate computing modules linked together into a single unit. As long as the cores are the same type of speed it will keep getting better and better. The new 64 bit which have quad cores which are the newest.


Cache memory is extremely fast memory that is built into a computer’s CPU, or located next to it on a separate chip. The CPU uses cache memory to store instructions that are repeatedly required to run programs, improving overall system speed. The advantage of cache memory is that the CPU does not have to use the motherboard’s system bus for data transfer. Whenever data must be passed through the system bus, the data transfer speed slows to the motherboard’s capability. The CPU can process data much faster by avoiding the bottleneck created by the system bus. There are usually 2 or 3 sections of cache for storing the extra commands because its extremely fast, a lot faster then the RAM so it can get the commands quicker.

Memory size

Memory size is an extremely important part of computer development. The Memory size always should be increased but not to large or it would be a waste of space. The memory is required to transfer the commands and is commonly mistaken for the hard drive and storing data. The memory is only used for temporarily storing the data and then execute the commands at the CPU. However, system memory relies heavily on how much RAM you have as well.
