1. GPU’s
Define what is meant by a Graphics Card:
A graphics card basically does maths calculations to make the graphics look better
What different types of cards are available in the marketplace and what price ranges do
they sell at?
There are many different cards and the can range from £50 on the low end and and
£300 on high end ones
What speeds do the cards run at and what impact does the speed have on the
performance of the card?
Speeds can improve the performance of computers by a lot and also can let the user
boost his graphics setting
What is meant by cache and why does a GPU often have it own cache onboard?
"Cache" is a specialized form of computer memory. In the case of Internet, "cache" is
commonly used in the context of "browser cache". Cache is designed to speed up the
computer by prioritizing its contents for quick access.
To speed up internet browsing
What is the difference between a 2D card and a 3D card (include in your answer details
about address/data bus; two-dimensional (2D) and three-dimensional
(3D) processors, eg what they can process in terms of pixels, polygons, nurbs)?

2. "2D graphics" is exactly as it sounds... graphics that only deal in a 2 dimensional space.
3D graphics use a 3d coordinate system and vector graphics to plot/draw things.
Because things are in a 3d space, objects can be in front of other objects. Objects can
be displayed from a perspective viewpoint in which the further an object is from the
viewpoint, the smaller the object will be. Only after all the calculations for the placement,
perspective size/angles, lighting, colors, and textures of the objects are made, is the
image is rasterized (turned into a flat 2d image that is displayed on the screen.) 3D
graphics API's often have many features built in that allow the creation of nice effects
such as reflections and light/shading.
What GPU is in the PS4 and XB1?
Ps4 has
x86 PC CPU
xbox 1 has Shader Cores: 768

3. Displays
Research the current displays that are used for gaming. Look at both portable gaming
and in the home. Create a factsheet that covers :Built-in displays; (displays on pads (VMU) and handhelds)
Are the displays liquid crystal?
Colour or monochrome?
External displays; (Monitors, Televisions, Projectors)
resolutions,
connectivity
Colour or monochrome?
