Why is PCIE2 0 enough for today s graphics cards? 50

lz,Please choose my answer,I'm a deputy moderator of the Pacific Forum,I've studied this problem,The bandwidth is very generous for the current graphics card,For 690,Dilan7990This dual-core flagship has an effect,In the case of and are enough,The high-end graphics card of the non-current top dual-core flagship is enough。

And if your machine is a P67,Z68 motherboard,To upgrade, you don't need to upgrade Z77 at all,Unless you are dual SIM 680 or 7970,Single card 670,680 is no different from playing games。 The bandwidth is there and it is not outdated, except, of course, the embossed double SIM or even 3 cards.

Definitely enough, because now hindering the speed of the computer, is on the hard drive.

Nowadays, the speed of computers like CPUs, graphics cards, and memory is enough, but the problem is that the speed of the hard disk is slow, and you use an SSD, which is not as fast as the CPU, graphics card, and memory, so most of them don't need to care about the speed of the graphics card.

Nowadays, the speed of computers like CPUs, graphics cards, and memory is enough, but the problem is that the speed of hard disks is slow, so you use SSD, and its speed is not as good as CPU, graphics card, and memory, and most of them don't care about the speed of the graphics card.

The highest graphics card does not exist. It's just a matter of whether it can be used to the maximum effect.

The difference between different versions of PCIe is in the data throughput. The specific throughput is shown in the figure above. Your PCIe2 can support up to 8GB s of throughput.

What is this concept? A frame of 1080*1920 has 2 million pixels, assuming that a pixel needs 8 bytes to describe, then the size of a frame is 16 million bytes, and 8G is 8 billion bytes, which is equivalent to transmitting more than 500 frames per second. Well, that is, it can support 1080@500hz graphics cards.

The 4K resolution is 4 times the 1080 pixels, so the frame rate is about 125HzIt's the equivalent of a 4k@120hz graphics card.

That's pretty much the best graphics card you can buy right now. The question is, do you have such a good monitor?

Highest graphics card.

Any graphics card that is equivalent to or has a PCI-E graphics interface, whether it is the latest or the oldest, as long as it is a PCI-E interface, can be installed on your motherboard.

1. Different maximum data rates:

PCI-E 2 can only provide a maximum data rate of 5GT s, while PCI-E 3 has a data transfer rate of 8GT S, which increases the bus bandwidth. The PCI-E specification increases the data transfer rate to 8GHz|8Gb s (also initially expected to be 10GHz), maintaining PCI-E 2 backward compatibility. x/1。

and continue to support and 5GHz signaling mechanisms.

2. Different encoding methods:

PCI Express operates at 8GHz, eliminating the traditional 8B 10B encoding. It will introduce a number of techniques, including enhanced signaling, data integrity, transmission and receive equalization, PLL improvements, time-pulse data recovery, and general scaling.

Up to NVIDIA RTX4080 is supported.

Nvidia RTX4080 and other 40 series discrete graphics cards use interfaces, which are compatible with each other. If there are only expansion slots on the motherboard, the RTX4080 can technically be installed. However, the graphics card can only be used for data transmission and exchange in a standard manner, which has a certain impact on its performance.

It is the third generation of PCI-SIG, a PCI Express technical standards organization, and is a rapidly evolving version of the PCI Express.

At the same time, the 128B 130B decoding mechanism is specially added, which can ensure almost 100% transmission efficiency, which is 25% higher than the previous version of the 8B 10B mechanism, thus doubling the transmission bandwidth and continuing the consistent tradition of the PCIe specification.

Tips for choosing a graphics card

1. Choose a graphics card that suits your needs.

Before buying a graphics card, you must first determine your needs, such as the computer usage scenario, the required game discrimination rate, the type of game, etc., these factors will have requirements for the performance of the graphics card. Therefore, it is important to choose a graphics card that suits your needs.

2. Select the graphics card according to the configuration of the computer.

The performance of the graphics card is closely related to the computer's companionship, and if the computer's other hardware is not enough to support the performance of the graphics card, then the performance of the graphics card will be limited. Therefore, when buying a graphics card, you need to choose the right graphics card according to the hardware configuration of the computer, such as CPU, memory, and motherboard.

3. Consider the power consumption and heat dissipation of the graphics card.

The graphics card generates a lot of heat when it is working, so it needs good heat dissipation performance, otherwise it will affect the performance and life of the graphics card. In addition, the power consumption of the graphics card also needs to be considered, if the power consumption of the graphics card is too high, it may lead to insufficient power supply or too many hot search links, affecting the normal operation of the computer.

Yes. First of all, the PCI-E 16X standard graphics card interface looks the same, whether it is or not, the interface is the same, and it can be compatible with each other. However, it should be noted that the speed of the graphics card inserted into the motherboard cannot be exerted, because the speed of the motherboard is slow, which will affect the performance of the graphics card to a certain extent.

and .

PCI-E is either x16 or still or rather, this is universal. The bandwidth of x16 is not as high.

It's an upgraded version of the x16, and that's the only difference. PCI-EX16 is a graphics card slot type. 0 is the technical specification, so of course it can be used.

There is only one point, that is, the graphics card, on the motherboard, the test shows yes. Because the graphics card has to be on a supported motherboard, it can be displayed.

The latest RTX40 series graphics cards continue to be used and will not be upgraded to the latest.

The reason for this is probably due to the fact that the current graphics card performance is not yet fully utilizing the full bandwidth. After all, for the current graphics card, the amount of data exchanged by itself is limited, and the bandwidth of the graphics card slot is enough, even if you use the graphics card slot, the bandwidth is wasted.

You must know that the performance of RTX30 series graphics cards is no different from that of Xia Weiyou. Therefore, under the premise that the graphics card slot is completely sufficient, players do not need to pursue the gorgeousness of the data, and choose products with graphics card slots.

How the graphics card works

The graphics card is plugged into the expansion slot on the motherboard (usually the PCI-E slot, and before that there were AGP, PCI, ISA and other slots). It is mainly responsible for converting the display signal sent by the host computer to the display into a general electrical signal, so that the display can understand what the personal computer is asking it to do.

The graphics card is mainly composed of the graphics card motherboard, display chip, display memory, heat sink (heat sink, fan) and other parts. The main chip of the graphics card is called the "display chip", which is the main processing unit of the graphics card. It means that there is also memory similar to computer memory on the graphics card, which is called "display memory", referred to as video memory.
