What are the interfaces between common graphics cards and motherboards and what is their transfer sp

The former of AGP and PCIe has long been phased out, with a transmission rate of 2133M (AGP8X).

The latter transmission rate is 10240M (PCIe16X

In fact, this transfer speed is all theoretical, in fact, it doesn't need that much at all, don't worry, those are not a problem, choosing the right graphics card is the right thing.

I'm too lazy to write.,I took a screenshot of the nuc at hand and showed it to you.,1.Memory bandwidth,Single memory 64bit,Dual channel is 128bit,Bandwidth is related to memory frequency,2133Frequency is this 34133MB bandwidth,Read and write,That is, the actual bandwidth,In addition to being affected by frequency and bit width,It is also affected by the northbridge frequency and memory timing,The default northbridge frequency is 3G,I remind you,This may not be a reference value for you,Because 2133The memory timing is a lot,My memory timing is 11 11 11 31

3.The PCI question you asked, M2 is 32GB S, that is, 4GB S, because 4 PCIe are used, so 16 is 16GB S, 128GB S, and the same X1 is one, that is, the maximum 1GB S, 4The question you asked about M2 and SATA, this M2 can play a very good performance for the SSD used in NVME, it has not yet reached the theoretical limit of 4GB S, but it has broken through the speed of 1GB S, NVME's M2 and SATA SSD read and write speed, you can see my machine above, these two are relatively cheap goods, PM951 and 850evo, SATA3 is the most common SATA hard disk interface.

5.This idea is extravagant, because the actual speed can only approximate the theoretical speed, which can only be achieved by idealization.

The hardware listed in the problem, the most critical is the choice of CPU, the CPU is selected, after the motherboard is selected, these two things are decided, then the prototype of the computer has been basically determined, and other hardware is piled up on the basis of these two, but it is a supporting role.

The choice of CPU performance is a decision of the application and the game, the graphics card is also a game decision, if you do not play, the nuclear display is on the line, and the other choose the supporting hardware according to the budget, but you need to pay attention to the power supply, it is recommended to have a higher rated power.

In general, there are two kinds:

1. AGPAGP, the full name of Accelerated Graphic Ports, is a kind of graphics system interface for PC, which has been eliminated at present. At the time of the emergence of this technology, 3D graphics acceleration technology became popular and rapidly popularized, and in order to obtain higher bandwidth than the PCI bus for data transmission between the system and the graphics acceleration card, AGP came into being.

2,pci-e:

PCI Express is the next generation of bus interfaces. As early as the spring of 2001, Intel proposed to replace the PCI bus and the internal connection of a variety of chips with a new generation of technology, and called it the third generation of IO bus technology. Subsequently, at the end of 2001, more than 20 industry-leading companies, including Intel, AMD, Dell, and IBM, began to draft specifications for the new technology, which was completed in 2002 and officially named PCI Express.

It adopts the popular point-to-point serial connection in the industry, compared with the shared parallel architecture of PCI and earlier computer buses, each device has its own dedicated connection, does not need to request bandwidth to the entire bus, and can increase the data transmission rate to a very high frequency, to achieve high bandwidth that PCI cannot provide.

The most popular one is PCI-E slots. The best in the PCI-E slot right now is the version.

PCI-E: Higher bandwidth, lower latency Compared with PCI-E, PCI-E's goal is to continue to double the bandwidth to 10GB S, to achieve this goal, it is necessary to increase the speed, PCI-E's signal frequency has been increased from 5GT S to 8GT S, and the coding scheme has also changed from the original 8B 10B to a more efficient 128B 130B, other specifications are basically unchanged, and 2 bits of data are still transmitted per cycle, supporting multi-channel parallel transmission.

In addition to the significant increase in data throughput due to the doubling of bandwidth, PCI-E has faster signal speeds and correspondingly lower latency for data transmission. In addition, there are specific optimizations for software models, power consumption management, etc. Put simply, PCI-E is like the highway, with faster cars, lower starting intervals and more comfortable seats.

There is ISA PCI AGP AGP4x agp8x PCI-e, which is transitioned from generation to generation, and the previous one is the oldest... Nowadays, most of them are PCI-E, and some motherboards also have AGP8X, and some motherboards also have two PCI-E ports that can form an ATI firefight to enhance the performance of the graphics card.

It used to be called AGP interface, but now it has been eliminated. Now it is generally the PCI-E interface, and the mainstream is that the PCI-E x16 or PCI-E bit width will be twice as small.

Now it is basically a unified PCI-E x16 interface.

As long as the graphics card socket is the same as the motherboard socket, it means that it can be installed, but there are many other factors to consider when changing to a relatively suitable graphics card.

1. The graphics card generally only needs to match the interface. Compatibility problems can only be known by testing on the computer, but incompatibility is rare.

2. When changing the graphics card with the same interface, you should also consider the performance of the CPU. For example, if it is a dual-core or i3 processor, you can use a mid-range graphics card such as Jingying GTX650 or HD7750, and you can use up to GTX750. If you want a GTX560Ti or higher graphics card, it is recommended to have a minimum of 4 cores or i5 processors.

That said, the better the performance, the higher the processor requirements.

3. Different graphics should be equipped with different power supplies. Because the power supply is small, it will also crash and lose power. For example, if the graphics card power is below 70W, use the ** power supply rated above 300W.

If the power of the graphics card is about 70W-140W, it is recommended to use a ** power supply rated above 400W. If the graphics card is a high-power graphics card like GTX770 that is about 230W, it is best to use a ** power supply rated at more than 500W.

Not all motherboard graphics card interfaces are the same.

The interface type of the graphics card refers to the type of interface used to connect the graphics card to the motherboard. The interface of the graphics card determines the maximum bandwidth of data transmission between the graphics card and the system, that is, the maximum amount of data that can be transmitted in an instant. Different interfaces can bring different performance to the graphics card, and also determine whether the motherboard can use this graphics card.

The graphics card can only be used if there is a corresponding interface on the motherboard. Since the development of graphics cards, there have been several interfaces such as ISA, PCI, AGP, etc., and the data bandwidth that can be provided has also increased sequentially. The current popular PCI Express interface graphics cards were introduced in 2004.

The graphics cards with ISA and PCI interfaces have been basically eliminated. AGP is also only available on old aircraft.

The graphics card is not inserted casually, the older graphics card is a PCI interface, and later replaced with an AGP interface, and now the new motherboards are all PCI-E interfaces.

When the new motherboard is plugged into the GPU, it will automatically block the integrated display.

The integrated graphics card is made on the motherboard, and you can't pull it out if you want to pull it down, and after you plug in the discrete graphics card, it will automatically block the integrated graphics card. Only high-end motherboards have integration and a discrete display firefight.

The graphics card is mainly divided into PCI E slot and agp slot, what slot is inserted into what motherboard, you don't need to pull out the integrated graphics card with a discrete graphics card, you can't pull it out... It's integrated on it.

There is PCI, there is AGP 2X (X: double speed, Speaking: Speed X, 8X, there is PCI-E16, the second one is partially compatible.

The output of the graphics card basically has only four interfaces, and in order of transmission quality, it should be S terminal, VGA, DVI, HDMI

DVI and VGA, DVI is digital output and VGA is analog output.

A detailed explanation of the three interface types of notebook desktop computer LCD TV LCD screen.

At present, the graphics card interfaces that can be used by mainstream desktop computers include PCI, AGP, and PCI Express;

PCI E is currently the most widely used interface in personal computers.

There are three most common types, which are VGA, DVI, HDMI. The resolution is the highest in HDMI, followed by DVI, and VGA in general. But the most used is the VGA (Historical Problem).

If you ask about the interface of the motherboard, then most of them are PCI or PCI-E interfaces, basically as long as the motherboard is not too old, it will have this interface.
