Desktop and notebook graphics card chips are distinguished

A notebook graphics card with m on the back.

First, the subject is different.

1. Graphics card: It is one of the most basic components of personal computers, which is used to convert the display information required by the computer system to drive the display, and provide progressive or interlaced scanning signals to the display.

2. Display chip: It is the main processing unit of the graphics card, so it is also called the graphics processor.

Second, the technology is different.

1. Graphics card: The various 3D special effects supported are determined by the performance of the graphics chip, and what kind of display chip is used roughly determines the grade and basic performance of the graphics card, such as NVIDIA's GT series and AMD's HD series.

2. Display chip: The core technologies used include hardware T&L (geometric conversion and lighting processing), cubic environment material mapping and vertex blending, texture compression and bump mapping mapping, dual texture four-pixel 256-bit rendering engine, etc.

Third, the role is different.

1. Graphics card: responsible for converting the display signal sent by the host to the display into a general electrical signal, so that the display can understand what the personal computer is doing.

2. Display chip: The graphics card reduces its dependence on the CPU and completes part of the work that originally belonged to the CPU.

The graphics card, i.e., the graphics card, is a piece of hardware, and the graphics chip, i.e., the GPU, is a chip.

The graphics chip is installed on the graphics card, the graphics card is used to receive digital signals, and the display chip is responsible for converting the digital signal into a graphic signal, which is output to the display by the graphics card.

There are tens of thousands of professional graphics cards, and the display chips of professional cards are different from those used for games, and the display chips used in games are removed from the professional design that ordinary people can't use, in order to reduce costs; The professional card is for professional image processing personnel, such as the special effects processing of movies, etc., many of the movie CGs you see have to be rendered for a long time to make, and they can't be completed with game cards at all!

The display chip is soldered on the graphics card, and there is also video memory, capacitor and inductance on the graphics card, etc., and it is useless without these display chips.

It is the number of data transmission bits used inside the display chip, and the current mainstream display chips basically use a bit width of 256 bits, and the use of a larger bit width means that the data transmission speed remains the same, the larger the amount of data that can be transmitted instantaneously. Just like valves of different diameters, under the condition of a certain water velocity, the larger diameter can provide a larger amount of water. The bit width of the display chip is the bandwidth of the internal bus of the display chip, and the larger the bandwidth, the faster the computing power and data throughput capacity that can be provided, which is one of the important data that determines the display chip level.

At present, the maximum bit width of the display chip is 512 bits, which is the Parhelia-512 graphics card launched by Matrox, which is the world's first display chip with a width of 512 bits. At present, all mainstream graphics chips in the market, including NVIDIA's GeForce series graphics cards, ATI's Radeon series, etc., all use 256-bit bit width. The two largest display chip manufacturing companies in the world, which are currently the world's largest, will also adopt 512-bit width in the next few years.

The increase in the bit width of the display chip does not mean that the performance of the chip is stronger, because the integration of the display chip is quite high, and the design and manufacturing require high technical capabilities.

The bit width of the video memory is the number of bits of data that can be transmitted by the memory in a clock cycle, and the larger the number of bits, the greater the amount of data that can be transmitted in an instant, which is one of the important parameters of the video memory. At present, there are three kinds of memory widths on the market: 64-bit, 128-bit and 256-bit, and people are accustomed to calling 64-bit graphics cards, 128-bit graphics cards and 256-bit graphics cards to refer to their corresponding memory bit widths. The higher the memory bit width, the better the performance**, so the 256-bit wide video memory is more used in high-end graphics cards, while mainstream graphics cards basically use 128-bit video memory.

As you know, the memory bandwidth is 8, so in the case of the same memory frequency, the memory bit width will determine the size of the memory bandwidth. For example, if the same memory frequency is 500MHz for 128-bit and 256-bit video memory, then their memory bandwidth will be: 128-bit 500MHz*128 8=8GB s, and 256-bit 500MHz*256 8=16GB S, which is twice that of 128-bit, which shows the importance of memory bit width in video memory data.

The video memory of the graphics card is composed of pieces of video memory chips, and the total bit width of the video memory is also composed of the bit width of the video memory particles. Memory bit width Memory particle bit width Number of memory particles. The memory particles are equipped with the memory number of the relevant manufacturer, you can go to the Internet to find its number, you can understand its bit width, and then multiply it by the number of memory particles to get the bit width of the graphics card.

This is the most accurate method, but it is more cumbersome to implement.

At present, there are four main manufacturers of display chips, NV, ATI, INTEL and VIA. Among them, Intel and VIA's chips are almost all in the integrated graphics card market (VIA has very few discrete cards, but they are basically not found). Independent graphics card chip manufacturers can basically think that there are only two NV and ATI.

If it is only a chip, it cannot complete the graphics rendering work of an ordinary computer, and it must also have a circuit board, video memory, power supply module, etc. that are matched with the chip to become a "graphics card".

As for the display chip and the graphics card model, there is no necessary relationship, you can also call her a 9800 whirlwind or something if you use a 9600 chip to make a graphics card, but most major manufacturers will bring the core in their naming, such as GTX 460 Destroyer or something.

The graphics chip is an important part of the composition of the graphics card, and the relationship between the graphics card and the display chip is like the relationship between the motherboard and the CPU, and the appearance is the same, it is a circuit board and a chip.

The graphics card is GPU + video memory + analysis circuit +.But the display chip refers to the GPU.

Laptop graphics cards and desktop graphics cards, except for the model numbers are relatively similar, the difference between the physical objects is clear at a glance, and no one will confuse it.

The most obvious difference is that laptop graphics cards are either soldered to the motherboard or use the MXM connector, but they still fit snugly against the motherboard's surface, while desktop graphics cards are plugged vertically into the PCI-E connector on the motherboard.

The notebook graphics card basically does not have an output interface, but borrows the output interface of the integrated graphics, so if you use an XP system that does not support the switching of dual graphics cards of the integrated graphics card, only the integrated graphics card can continue to be used in the two graphics cards, and the independent graphics card will be disabled because it does not have the output capability. The desktop independent display must have an independent output interface, and there is generally more than one. This is another distinction that is clear at a glance.

Laptops and graphics cards all have an M in their model numbers, while desktops don't.

Notebooks and desktop graphics cards with the same model number can only indicate that they are the core of the same generation (and sometimes not), and they are similar in terms of market positioning, such as GTX970M and GTX970 both represent the level of high-end sub-flagships, and GT610M and GT610 both represent low-end entry levels. However, their actual performance is often more than 30% different, and the power consumption is as low as that of a desktop graphics card.

Take NVIDIA's graphics card as an example, the PC graphics card is prefixed with GTX, GT, GTS, and the notebook graphics card is followed by an M, such as GT650M, AMD's graphics card should be similar.

Laptop graphics cards generally have an M behind them, and the performance of desktops is stronger than that of notebooks and desktops of the same model.

Look at the suffix to have M to distinguish it, the same model of desktop graphics card is much stronger than the laptop graphics card.

Graphics cards are different. Notebook graphics card models generally come with an M. GTX850M like this.

1.The laptop graphics card and motherboard go together.

2.Desktops are truly self-contained.

3 You can see that discrete graphics cards are used on desktops.

4.You just look at it and you know,How to install such a large discrete graphics card on a desktop 5There is a difference,The same model of notebook graphics card and desktop graphics card are completely different。 Laptop graphics cards reduce power consumption and reduce the size, and desktops can't be put on laptops.

It's definitely different, the memory of laptops is very small, while the memory of desktop computers is 2nd and 3rd generation, and the area is nearly twice as large as the memory of laptops.

It's not the same. The graphics card of the laptop is a mobile chip. Limited by heat dissipation, the overall performance is half a grade worse than that of desktops.

Some are about the same, some are different, let's put it this way, the worse the graphics card, the lower the power, the smaller the gap between the desktop and the notebook, the greater the power, the more high-end, the greater the gap between the notebook and the desktop.

The model is the same, but there is a gap in performance, because the notebook is a low-voltage version

For the same model, there is a big difference in the performance of laptop and desktop graphics cards. The power and heat dissipation of desktops, laptops are far inferior. So it's different.

The graphics card of a laptop is not the same as the graphics card model of a computer. If you have to compare it, the desktop one is better, and it is better than the notebook graphics card of the same price.

The same model of graphics card, notebook and desktop are also different.

There is still a difference between a model of graphics card, a laptop and a desktop.

Because of the space, the graphics card is generally smaller, considering the power consumption and heat dissipation problems.

The desktop still has independent heat dissipation, so the performance at the beginning of the material is much better.

The same model of graphics card notebook and desktop are definitely different because there is a difference.

The difference between the desktop and the notebook graphics card is that there is an M in the back, but the performance is not the same, and the desktop is much more powerful than the notebook graphics card.

It's not the same, the desktop has a larger graphics card, and the heat dissipation performance will be a little better, but the laptop has limited space after all, so there may be a little difference in performance.

The same model of graphics laptop and desktop are the same, and there is no difference in performance.

Because although the model of the notebook and the desktop graphics card are the same (the notebook has the word M or mobility for the mobile version), the core is different.

Just like you said about the mobile version of the GT540M, the core is actually the same as the desktop version of the GT430.

PS: There is no GT540 in the desktop graphics card.

The mobile version of the graphics card is generally a downclocked version of the desktop version of the lower-level graphics card. For example, the mobile version of HD5870M is 800SP, 128bit, and GDDR5And this spec is actually the desktop version of the HD5770.

The desktop version of the graphics card corresponding to each mobile version of the graphics card is different, and the frequency is also different, so it is difficult to explain the performance gap, but there is at least a 30% performance gap in the same model, and the lower the graphics card, the smaller the gap. The more high-end the graphics card, the bigger the gap.

Laptops and desktops have different graphics cards of the same model.

No, the notebook is a little worse.

It's definitely different.,And where did you come from the same model?,Notebook desktop is different.。

You can know by looking at the parameter table when you buy.

There are two kinds of integrated graphics cards in notebooks, one is the graphics card integrated on the motherboard, and the other is Intel's new CPU i3 i5 system, which has been added to the graphics card in the cup.

A discrete graphics card, on the other hand, is a separate board, just like a memory connected to the motherboard through a slot. Discrete graphics cards are generally divided into A cards and N cards. The A card is an ATI graphics card acquired by AMD, while the N card is a graphics card produced by NVADIO.

Both graphics cards are very good.

It is recommended that if you are only using it for office and Internet access, you can use the integrated graphics card. This also extends the standby time of the notebook. If you want to work with 3D applications, you choose a discrete graphics card.

Of course, if it is a cup of the i5 system, some notebooks can integrate graphics cards and independent displays, which can be easily switched.

What is the difference between a laptop integrated graphics card and a discrete graphics card?

There is a clear sign on the outside of the notebook, you can also go to my computer, properties, and device manager to see the graphics card, and there is also information about the graphics card under the right-click properties, settings, and display on the desktop. Or go directly to Start -- Run -- type dxdiag -- select the Display tab Is it integrated, and it will write graphics or something like that in the name.

I see that there is ATI or NVIDIA graphics card chips, all of them are independent graphics.

1.The easiest way to do this is to look at the labels:

Laptops have labels on them, one is definitely for the CPU, and the other is for the graphics card (if not, it can only be said that it is integrated).

2.Looking at the power consumption, if the standby performance of a computer with similar battery performance is far from the standby performance, it can only mean that the standby time is short is the discrete graphics card (sometimes it may not be accurate, affected by energy-saving software, wifi, etc.).

3.Use software,GPU-Z is a special software specially used to test the graphics card category,You can use it to distinguish,If the display core of the display is ATI or NVDIA graphics card,Then he is a discrete graphics card,If it's Intel,It's likely to be an integrated graphics card,Just confirm the model on the Internet (but Intel also has a discrete graphics card,GMA series,But the performance is very poor,Whether Intel's graphics card is independent or integrated,The performance is not very good。

4.Test performance,3DMark is a set of more professional software,The higher the score, the better,If you don't want to use this more professional software,You can also use Master Lu。
