CPU,GPU and Memory

CPU

The phrase CPU stands for Central Processing Unit. The main Function of the CPU is to handle everything all the different processors of the PC/game console. The CPUs main purpose changes if it is in a PC or a home console. this is because they both have different functions, while the game console only has to handle playing games so most of the CPU is used to control memory, graphics and store other bits of information. While in the cause of a CPU in a PC then it has to handle a lot more tasks so it has to be changed to meet all these demands. 

A CPU works by in side is a very large number of switches that turn on or off so for it to preform certain actions certain must already on. For example:

The first switch would only active when you were close enough to a door, once it had been switched on you would then be able to access the second layer of switches deciding if the door was open or not.

Even though the CPU preforms nearly the same function in a PC as in a home console. They are in different places on the motherboard. The CPU on the computers motherboard is places below the heat-sink because it is the most effective place for it to be. while in the case of a home console it is usually places next                                                                                           to the heat-sink and near the GPU.

Differences in systems of ps1 and ps3

There is a huge number of differences between the CPUs of the ps1 and the ps3, this is mainly due to the several years difference between them. So it is only natural that the Central Processing Unit would have improved a great amount. 

In the case of the PS1's CPU is it a 32 bit RISC microprocessor,  This sort of processor worked at either 20,25 or 33.33 MHz, this was able to handle up to 4kb cache. The most impressive part of the CPU is that it had a geometry transformation engine allowing 3D animations, the features of this engine are:

operating system at 66 MIPS (million instruction per second),

360,000 polygons a second,

& 180,000 textures mapped and light sourced per a second.

While as expected due to the increase of technology the PS3 works a lot faster because of its CELL micro-processor, it works at a much higher speed than these predecessors CPU working at a incredible 4GHz.

Multiple Core Processor

A Multiple Core Processor is a process with more than one CPU this means that it is able to run a considerable number more instructions at any one time making it overall faster and smoother. The main reason that a Multiple Core Processor is able to work faster and smoother is because they are able to handle a lot more different instructions.

GPU

GPU stands for Graphic Processing Unit and its main function is to handle the immense calculations involved with rending the 2D/3D image. The processor would have special instructions to handle a number of things like Modelling transforms,lighting ,animation, texture and the overall rendering process. The processor can be found on the motherboard of any console while in the case of a PC it can be bought as a graphics card, allowing your to make the overall gaming process on a PC a lot smoother and better.


Every electrical device that has come kind of screen will have a Graphics processor (phones,consoles,computers,laptops and several smart televisions). Out of all these devices computers normally have the most powerful GPUs because you are able to upgrade them to get more out of them, shortly followed by the GPUs in consoles which are top of the range when they are first made but being unable to be upgraded mean that they become out of date rather quickly. Phones most likely have the weakest GPUs because high end graphics are not needed in a phone, just enough to play a few simple games.
Arguably the best graphics card on the market is the AMD Radeon HD 7970 GHz edition, which was made to celebrate the Radeon HD 7970's 6th month birthday.  The vital stats for this graphics card are a GPU powered by Tahiti XT and an impressive clock speed of 1,050 MHz with an equally impressive memory capacity of 3GB. This one of the best graphics cards on the market and it is because of upgradeable parts that PC has always and always will have an advantage over consoles and other graphic devices.
Due to the fact that home consoles can't be upgraded then the xbox 360 falls in comparison to the modern PCs so to try and make people forget that the xbox is nowhere near as good as a PC the best possible GPU has to be added to mean that the console at least stands a chance of keeping up with the rate that graphics are improving. So when the Xbox was realised in 2005 it was given the Xenos graphic chip, this isn't as impressive as the Radeon but still has a clock speed of 500 MHz.

Memory

Memory is often referred to as RAM which stands for random access memory, the whole point of this is that you are able to access this at any point your please. This works brilliantly on computers because it allows you to access different saved files when you pleased, while in the case of gaming consoles it works as checkpoints allowing the player to return to any point they please if they had reached it yet. This makes it quite important in the case of gaming because if we didn't have it the player would have to restart the game every time you were too insert it into the game. There is a different memory in the case of the CPU and GPU because it is where all the save states and files are saved too while in the case of the CPU stores the programs and the GPU handles and stores the graphic pipeline.
