What is CPU?
CPU is short for Central Processing Unit. It was first developed at Intel with the help of Ted Hoff in the early 1970’s. It’s commonly known as the brain of the computer as it does anything instructed from any type of hardware, such as your keyboard and mouse. CPUs process commands it receives from decoding the code in programs and many other files. A CPU has four primary functions: fetch, decode, execute, and writeback. Computerhope.com, (2014)
How does a CPU change computer performance?
Firstly for the fetch step, which is the CPU receiving the command that it needs to run a program from memory. Each command in a program, which may contain more than a million commands, is stored at a specific address. The CPU has a function…show more content… Some power supplies do not provide efficiency, but most power supplies provide at least 80% efficiency. Depending on the efficiency the better power supply performs and saves electricity.
There are advantages to having a power supply with high efficiency. It can reduce electricity bills to save money, and produce less heat to avoid over heating problems within the PC. Hardwaresecrets.com, (2014)
What is RAM?
RAM is short for Random Access Memory. It can be referred to as the main memory or system memory. RAM is a computer storage location that allows information to be saved and retrieved quickly from random locations within DRAM (Dynamic Random Access Memory) on a memory module. DRAM was originally invented by Robert Dennard in 1968 and first released commercially by Intel in October 1970. DRAM stores information in a cell with capacitor and transistor; due to this design, the cells must be re-energized with new electricity every few milliseconds allowing memory to keep its charge and hold data.

Typically the GPU is integrated to the CPU and is completely separate from the motherboard, but sometimes the CPU and GPU can be separate from each other as some motherboards do include a GPU slot, which is called the PCI express.
Most GPUs process 3D computer graphics by using transistors. However, some already have built in accelerated memory for mapping vertices, such as geographic information system (GIS) applications. Today there are some GPU that have the feature to program shaders, implementing textures, mathematical vertices and accurate colour formats.
GPU Accelerated Computing
GPU accelerated computing is the combination between a CPU and GPU to accelerate intense applications. GPU accelerated computing provides extraordinary application performance by offloading complete-intensive parts of the application to the GPU, while the rest of the code is still running on the CPU. This significantly increases applications speed and quality at the same time.
