Types of graphics cards and how to choose them



There has been a lot of controversy recently among users of graphics cards about the comparison between Nvidia and AMD or ATI previously, and there has been a lot of discussion about the degree of quarrel - oral - and the exchange of opinions sometimes between some fanatics of users for each of them, and in this blog we will make a simple comparison between both Nvidia and And AMD let's find the difference between them, but before that let's present a simple summary about the graphics card, what is it? When did it start to use and what are its types?


What is a graphics card?

The graphics card, graphics card, video card, graphic card, Vega card, graphics card, Video card, graphics accelerator card, display adapter, graphics card, or VGA card are all names and terms for this small unit of device The laptop is responsible for handling and dealing with image, graphics and video files, creating and creating the image and showing it on the device screen, this small unit is responsible for everything you see on the desktop, icons, tags, pictures, video, windows, movies, games and everything that is located in your eye on the screen .
The majority of the companies that produce computers use the cards except IBM, they do not use graphics cards, but rather use another unit, "Commodore Amiga".

                   History of  graphics cards




The first video card was invented in the 1960's when it began to replace printers with screens as a color from virtual animation, so it was necessary to invent a graphics card to create images. The first video card that was sold on the market was from the IBM Foundation’s version in 1981 and it was called “MDA” for the “Monochrome Display Adapter” and it used one feature, which is the texts and its memory does not exceed 4 KB and only uses one color ..



Types of graphics cards

Professionals use two types of graphics cards:



Integrated card which is attached to the "Mother Board".
 The card is separate from the motherboard or external card.

There will be limited discussion here now on the second type, which is: the external card, which controls its change, dismantling and installation, and has dedicated entries for it, and for this type of shipping cards there are many chips and versions.


Factors to consider when choosing between screen cards
There are a number of things to consider when comparing one card to another:



GPU Speed
Memory Speed
Direct X card support
Time of arrival
Band Width
Refresh rate
GPU unit


There are two other things that must be considered:



Compatibility with computer units: It is unreasonable for a person to choose a higher-quality screen card for a processor with weak capabilities and low frequency, then strong performance is expected,
Nature of use: There is something that cannot be forgotten when choosing the appropriate screen card, meaning that a person asks himself - before he accepts to choose a particular card -: What will I use the card for?


If the use is for browsing and movies, then the most appropriate is the sufficiency of the integrated graphics card in the motherboard, because these applications do not need high processing, and cards for vulnerable groups can be used.

If the use of powerful games and large settings and you are a fan of design or working in it and use programs with high capabilities such as Photoshop and Adobe then the cards that are best for you is Quadro and tesla from Nvidia, or Firepro cards from AMD.


What is better NVIDIA or AMD - ATI

After you determine your need for the category to which the card you want belongs, it is the role of comparison between the best types of cards and there are two types of cards are the most common and revolve between them a severe symmetry and modern versions do not stop: Nvidia and ATI (formerly AMD or ATI), We will discuss both companies to try to compare them:



                                                                                             First:NVIDIA graphics card     

Nvidia calls its desktop product name "GeForce". The company issues its treatments in the form of four categories, for each category a number and then a code after the numbers a symbol consisting of several letters, to indicate the specifications of the graphics card
And they are as follows: ((ABCD FF)), the A represents the graphics card category - the B represents the model from the same category, the CD usually represents zeros, the FF represents the letters that give you data about the specifications of the graphics card, for example: 8600GT
Take an example: Nvidia Geforce 8800 GT, of course Nvidia Geforce is fixed in all Nvidia cards so the important part is 8800GT, and we analyze it as follows:
First: the categories category and divided into three sections


Cards whose name ends in 100, 200, 300, 400, or 500 are weak and slow category cards, and are not recommended, for example: Nvidia Geforce 7200 GS
Cards ending in 600 or 700 middle-class cards are recommended for those who want to play games, for example: nvidia geforce 8600 gts
Cards whose names end in 800, 900 or 950 are the highest category cards and are highly recommended and are very powerful and run all games on Maximum, graphics programs, Adobe and others, and examples are: Nvidia Geforce 8800 Ultra

Second: The word that comes after the card, and the words are:


Cards ending in LE are very weak and are not recommended at all.
Cards ending in GS are weak and not recommended.
GT cards are good and are significantly better than GS.
Cards ending in GTS, including 8800 GTS which is excellent, and 8600 GTS which is good.
Cards ending in GTX are very, very good.
The cards that end with Ultra, the most powerful cards ever, are single-core.
The cards that end in X2 which are very powerful cards are dual-core.

           Second: AMD "ATI"screen previously

ATI is a Canadian company founded in 1985 by three Chinese expatriates under the name Array Technologies Incorporated, and then transformed into an American company in 2006 from AMD in one of the largest deals in the technical world and since then it was named after AMD.
AMD calls its desktop card product name "Radeon", and also the company issues its treatments in the form of four categories, for each category a number and then a code after the numbers a symbol consisting of several letters, to indicate the specifications of the graphics card
The card is from the HD7000 generation. As for the hundreds box, it indicates the type of card. Is it from the upper or lower or middle category, and often the upper category, the number of hundreds in it is (9), and the middle category (8-7) for the pre-6000 series, the name varies in terms of number 8 It indicates the upper category, and the lower category below that, such as (6-5-4-3). As for the number of tens, it indicates the power of the card in the same category, for example, the card 7870 is stronger than the 7850, and the card 7770 is stronger than the 7750 and so on.
The most important benchmarks for NVIDIA and AMD comparison
First: In terms of the technology used:



                                              Power Efficiency

NVIDIA was able to eliminate the problem of withdrawing energy in exchange for performance, or what is known as PERFORMANCE PER WAT, so it increased its capabilities to withdraw energy in the new generation through the GTX600 generation and beyond, where the performance reached three times compared to previous generations.
Likewise, AMD has also increased its ability to draw energy in its new generation HD 4000, so it pulled the energy of the HD7000 generation cards compared to the GTX600 generation, not much, but the difference between them is simple, but it is in the interest of NVIDIA and GTX600 cards with a negligible difference.
Dynamic Clock Adjustment technology
It is one of the new features that AMD added in its processors first and then introduced NVIDIA in the name of GPU Boost, as the feature of GPU BOOST automatically raises frequencies when there is a program or game that uses the card and needs more graphic performance. Used and permitted to increase performance.
Multiple screens
This generation came from NVIDIA company capable of operating up to four screens with a card, not only this, but the company developed from this technology on the GK104 chip to operate with one card in the mode of operating three-dimensional 3D instead of two cards in the previous generation.
As for AMD, it was a pioneer in this field with its amazing AMD Eyefinity technology, which it developed in the fifth generation HD5000 with Eyefinity 2.0 technology in the third dimension with the possibility of multiple screen, which greatly increased the resolution and efficiency of the screen.

Anti aliasing

NVIDIA was in the previous generation of the type NVIDIA FERMI The new winding inhibitors were introduced FXAA and did not contribute sufficiently to improving the quality of the image.
 AMD responded by updating a number of tools used to improve image quality with the 7th generation of its graphics card, such as developing the SSAA and MLAA technologies, and it was able to reach better image quality by processing edges and edges of distorted images.
VIDIA PhysX feature
NVIDIA Physx technology is an exclusive technology that cannot be run on AMD processors, but the number of games that support this technology so far are few
In response to AMD on that exclusive technology that only works on NVIDIA cards, it supported the physical effects HAVOK on its cards. What distinguishes this technology is that it is open source, so it can work on all graphics cards and even central processors from any company.


Second: In terms of performance
As for NVIDIA, most of its energy from the last category consumes high energy and emits high heat
  As for performance versus price, every company has a card that achieves this metric well. For example, the AMD performance meter has the fastest dual card and NVIDIA has the fastest single card.
Third: in terms of compatibility
  The Nvidia card is characterized by speed, therefore it is preferred when those who are interested in games because it controls some of the characteristics of the processor, which reduces the load on it, which makes the device faster, but the defect that it leads to heating the card, which affects its performance, while the AMD card is much stronger in the field of graphics and large games.

Fourth: In terms of cooling


NVIDIA Most of its energy card consumes high energy and emits high heat, especially modern cards from Nvidia, whose temperature is very high, which sometimes leads to fluctuating performance, and affects its shelf life.
As for AMD, most of its cards consume suitable energy and emit reasonable heat, but some of the AMD cards have high heat and very large consumption in electricity.
Fifth: In terms of stability and safety - over the life of the piece -
NVIDIA and AMD cards live and endure more and can withstand 10 years, but with this terrible progress I do not think there is a card that will ever withstand the terrible challenges ahead
Sixth: in terms of graphics cards definitions


As for the definitions, Nvidia is characterized by the stability of its definitions, while AMD has few problems.
 After we turned around the topic, and exposed to the most important technologies that are characterized by both companies, it seemed that there is little difference between the NVIDIA screen card and the AMD screen card, and in general the two companies share the general manufacturing power and the power of the cooling system and the quality of manufacturing varies from one company to another ..
And if some NVIDIA minor privileges remain and the matter remains two things:
The price is the decisive factor in the preference between them, if you want the best graphics card and modern technologies, you must have the latest version of NVIDIA, but if you want a special card and lower prices then AMD is excellent.
If your use of the computer is normal, which processor is suitable for you, it will not cause problems, and if you are fond of running heavy programs and games, it is appropriate for you is NVIDIA, but if you are fond of graphics, for example, and you want to work at full capacity of the device and processor, it is appropriate for you is AMD.
