Graphics cards, also known as video cards or graphics processing units (GPUs), have different types and price ranges depending on their intended use and processing speeds. Nvidia and AMD graphics cards for gaming range from £173-£925 and £62-£1013 respectively due to their higher processing speeds of 938-2000 MHz and 2500-3700 MHz, which enhances gaming performance. In contrast, integrated graphics cards for office computers have lower speeds of 350-1150 MHz and cheaper prices from £50-£75 since gaming is not their primary function. GPUs contain their own onboard cache to quickly access and store frequently used important data in a cost-efficient way.

1. GPU’s
Define what is meant by a Graphics Card:
video cards are sometimes called graphics add-in-boards, abbreviated as AIBs,[1] with
the word "graphics" usually omitted. Virtually all current video cards are built with either
AMD-sourced or NVidia-sourced graphics chips.[1] Most video cards offer various
functions such as accelerated rendering of 3D scenes and 2D graphics
What different types of cards are available in the marketplace and what price
ranges do they sell at?
NVidia
The price range of an NVidia Graphics drive ranges from £173 to £925. Mainly
used for gaming PC’S
Integrated
The price range of an integrated graphics drive ranges from £50 to £75, this is
because it mainly used in office computers and not for gaming with.
AMD
The price range of an AMD graphics drive ranges from £62 to £1,013. Mainly
used for gaming PC’s.
What speeds do the cards run at and what impact does the speed have on the
performance of the card?
NVidia
GeForce GT 720M
AMD
AMD Phenom II
Integrated
HD Graphics 4600
938 – 2000
2500-3700
350-1150
The NVidia and AMD graphics are the two top end graphics drivers which are used for
computer gaming as it has the highest processing speed and in result of that it is used in
gaming on PC’S. On the other hand the integrated are mainly used for office computers
so they have a lower processing speed the reason why is because it is not used for
gaming most of the time.
What is meant by cache and why does a GPU often have its own cache on-board?
A cache is an item inside the computer that stores information that is used regularly and
seems important so it can be found a lot quicker. To be cost efficient the caches are
fairly small because it is only used to store valued data that can be accessed quickly.
