What is a graphics card?
A graphics card is a device inside a computer that displays image clarity, color, and overall graphical information on a display. Simply put, a graphics card is a connector between a CPU and a monitor.
That means nothing will come to your computer monitor except the graphics card. Now a question may come to your mind, if your computer does not have a graphics card, then how is your computer running? Although I will discuss this below, I will give you a few ideas.
Graphics cards are of two types, namely, external graphics card and built-in
graphics card. All motherboards currently on the market have built-in graphics,
so low-budget PCs do not require any additional graphics cards.
Why is a graphics card used?
If you look
at the low budget PCs in the market, you will find that they focus on CPU, RAM
and STORAGE instead of graphics cards. For low budget PCs, even if you don't
have a graphics card, you can build an "integrated graphics processor /
IGP". Relying solely on the IGP is not a bad thing. This is the case in
most offices, schools / colleges. But if you are a diehard gamer or content
creator, then a graphics card is essential for you.
Modern graphics cards (whether high-performance video cards or IGPs) manage 2d and 3d content display, drawing desktops, decoding and encoding video content of programs and games.
There are only two companies in the consumer market that make high-performance video cards - AMD and Nvidia. These videocards are commonly called GPUs (Graphics Processing Units).
However, it is better known as graphics card. Founder Edison's GPUs are the most consistent and strong performers, but the design is somewhat conservative.
And third-party companies (Asus, EVGA, MSI, Gigabyte, Sapphire, XFX, and Zotac) launch modifications from the founders, such as cooling fan design, overclocking, and LED mood illumination.
Some board-partners-founders release both the Edison and
modified versions. With the current IGP, common tasks can be done, but in many
cases GPU is required. Let's see what work requires GPU-
Professional
Workstation Users-CAD software or video and photo editing.
Productivity
Minded Users- To use Multiple Displays.
Gamers-RAM
and CPU as well as GPU required.
Graphics
cards are basically divided into two parts based on the work-
Dedicated
cards - professional workstations, scientific computing, calculations and
artificial intelligence work.
Two types of
cards are used for the above two types of work-
In the case
of consumer cards - Nvidia’s GeForce and AMD’s Radeon RX series.
In the case
of Pro workstations - Nvidia’s Titan / Quadro and AMD’s Radeon Pro and Radeon
Instinct series.
Currently
Nvidia is influencing both types of markets. But first we look at the consumer
market.
In 2021,
Nvidia is divided into two sub-brands - GeForce GTX and GeForce RTX. And AMD
has the Radeon RX and Radeon RX Vega families (though now almost extinct) and
the Radeon VII (which are nowhere to be found except in the pages of history).
Things to keep in mind about graphics cards.
Resolution and Monitor - Current minimum power cards can also display 3840 to 2160 pixels (4K) programs. But in the case of high performance games, it is not possible to give a good framerate performance with this card.
Video-card positions in games, geometry and lighting, and transforms images in real time. Therefore, the more detailed images and resolution of the monitor in the game, the more power graphics card is required.
The resolution currently used by gamers is 1080p (1920 by 1080p), 1440p (2560 by 1440p), and 2160p or 4K (3840p by 2160p). In a word, the graphics card should be bought according to the highest supported resolution of the monitor.
High-Refresh Gaming: For many years 60Hz monitors had panel-refresh ceiling, but now high-refresh gaming is 144Hz, 240Hz, even 360Hz but smooth performance on the monitor. Most gamers don't bother with extreme refresh rates, but high-refresh rates are an advantage over fast-action and competitive games.
HDR Compatibility: Graphics card has to be selected keeping in mind the capabilities of HDR. While this is not a very useful feature for many gamers, HDR is very important visually.
Rayo Vallecano vs. Salamanca G-Sync: free-sync is AMD and G-Sync is Nvidia, both adaptive sync tech has been used. If not, the games screen shows half.
Now that we know a lot about graphics cards, let's take a look at some of the comparative key factors between Nvidia and AMD.
Clock Speed: Clock speed determines how fast the core of a graphics card works. And the higher the core, the higher the speed. If the GPU is the same, the clock speed can be differentiated.
For example, GTX-3080 base clock-1,710MHz but RTX-3080 base clock-1,815MHz. However, the base clock and the graphics boost clock are completely different.
Boost clock manages to temporarily increase the speed when there is extra pressure on the graphics (keeping the thermal condition under control). It depends on the cooling system. The better the cooling capacity on that board.
Understanding Onboard Video-Card Memory: How much video memory is on the card is also an important issue. However, the amount of memory capacity the card usually holds is predetermined.
For example, a board built for 1,080p games will not support 4 / 6GB RAM, while a board for 1,440p / 2,160P / 4K games will support 8GB or more of RAM.
The wrinkles: Some boards have less GPU but more support for VRAM, which makes the price of the board a little higher than the regular version. Therefore, VFX, 3D programming, modeling, video editing is given more importance in national work than boost clock speed in VRAM.
Memory bandwidth: Memory bandwidth is another important feature that determines how fast data can be input and output from the GPU.
Memory type: AMD board HBM2 series AMD Radeon VII, RTX 2080, gaming can be done, and content creation with 16GB VRAM can also be done. HBM2 is actually used for video editing in Adobe Premiere Pro and for launching boards at minimal cost.
GDDR6, on the other hand, is called the workhorse of the modern GPU, with HBM2 disappearing. GDDR has almost all the AMD cards that have come out in the last ten years, which are also capable of running very high power games.
However, Nvidia has already added this new memory to the GDDR6X, which is able to effectively double the available bandwidth.
Things to keep in mind before buying a graphics card.
The above discussion may not be understandable to everyone. So before we buy a graphics card, let's take a look at some of the things to keep in mind -
Bandwidth
Many people may think that I am talking about buying a graphics card but why didn't I talk about memory first?
You see, more or less we all have a misconception that "the more memory graphics cards I buy, the higher the performance will be."
But that is not the point at all. The key here is bandwidth. The main fun of a graphics card is the bandwidth. The higher the DDR on your graphics card, the higher its bandwidth.
One thing to note here is that the DDR of the graphics card has nothing to do with the DDR RAM in your CPU. How fast the GPU can access memory is basically a matter of bandwidth.
The higher the bandwidth of the card, the faster the data exchange rate between the cores will increase. And the faster the data is delivered, the better and smoother your games and videos will be.
There are two things to keep in mind when it comes to bandwidth.
Clock speed
Bus Speed or Width
Remember, DDR5 RAM has twice the performance of DDR3 RAM at the same clock rate. So DDR5 of 1GB RAM is much better than 4GB of DDR3 RAM.
Memory
Graphics card memory is not a storage, it is basically a RAM. As discussed above, the higher the DDR of your card, the higher the efficiency of your CPU.
Bandwidth is more important than the amount of RAM or memory on the card. So more memory means more performance. You need to select the memory of your card based on how you work.
Shader core
The main function of a shader core is to render images. It has a huge impact on bandwidth. Shader cores basically work with 3D objects.
Each company names the shader core one by one -
Nvidia = CUDA Cores
AMD = Stream Processors
The more shader cores your card has, the greater its image processing capability.
CPU review
Many people say that it is better to buy a CPU and attach a good graphics card and work with it. But the main thing is to get a good output of a good quality graphics card, your CPU must be of good quality.
Suppose, if your CPU is Celeron, Pentium or dual core, then buying a more expensive graphics card there is nothing but a waste of money.
However, if your dual core CPU is of the update generation. In other words, if it is Dual Core 7 Generation, then a good quality graphics card can be installed there. However, I would suggest you to use at least Core i series CPU for graphics card.
Cooler option (heat sink and cooling fan)
In fact, there is not much to say about this. This is because almost all the companies in the market at present use good quality cooling systems in their graphics cards.
However, there are some companies that do not have the option of a cooler fan on the card to give a graphics card at a lower price. Which, of course, made the video an overnight sensation.
This is because if the card does not have a good cooling system while operating any high performance software or game, it can become extremely hot.
The main thing
You see, if you buy a graphics card from a good company at a good price, you will not be deceived in any way. But we are basically looking for good quality graphics cards at low prices.
As discussed above, Nvidia and AMD are two companies that make graphics cards in the market. And companies like Asus, EVGA, MSI, Gigabyte, Sapphire, XFX, and Zotac take cards from those founders, modify them, and launch them on the market.
The prices of graphics cards of good companies are also of high quality. Although some cards are available on a budget, the way software and games are being upgraded at the moment requires a good quality graphics card as well as your CPU.
