Please take a look at this card

This thing is not called a graphics card, it is called a TV card, it is plugged into the computer, and the purpose is to receive the satellite TV analog signal used in the TV set and convert it into a VGA signal that the computer can display. That is to say, plug this card into the computer, and use the FM software in the driver of this card to search for TV channels. Once you've tuned your channel.

Your computer can be used as a TV. Other than this use, it will not improve the performance of the computer.

As for the brand, I can't see it clearly on the map, so I can only confirm the brand of the main chip. You can't confirm the brand of the card.

I'll also explain the functions of several main parts on this card.

1 The protruding silver thing on the picture is called a high-frequency head. The high-frequency head is the core part of a TV card, through which the TV card converts the TV signal into a digital stream signal and transmits it to the decoding chip. The high-frequency head is divided into two types: analog and digital, and because the analog high-frequency head has poor anti-interference ability, it must be placed in a closed space.

2 The largest branded chip is called a decoder chip. The decoding chip is responsible for preliminarily sorting and compressing the collected digital signals into DMA data streams in the PCI bus, and then transmitting the data streams to memory through the PCI bus.

3 In the small figure below, the circular interface in the middle is called the S terminal. Generally speaking,TV card also has** collection function,You only need to put the analog **output equipment (such as video recorder, camera, TV, *** machine, etc.) ** signal access to the interface,You can collect the ** signal of the above equipment through the computer。

4 In the small figure below, the interface on the left is called the audio input interface. This interface is used to collect the sound of external devices, and is generally used with the S terminal to collect audio while collecting **.

5 In the small figure below, the interface on the right is called the audio output interface. For some TV cards, the built-in acquisition chip is not satisfactory for the acquisition and processing of sound, through this interface, the user can directly input the audio information in the TV signal into the audio input interface of the sound card, so as to collect the sound signal through the sound card. However, at present, some high-end TV cards have canceled this interface.

Eldest brother. No one understands that.

It is the lowest graphics core in the AMD 7 series**.

2.No, the two are completely different and the core frequency is more important point 3The flow processor can be understood as the core of the graphics card, and the rest, I can't tell you clearly, and there is no difference in nature.

The parameters of the Shuangmin Fire Cyclone 2 HD5550 V1024 Maverick Edition are:

Graphics chip: Radeon HD 5550 Manufacturing process: 40nm core code:

Redwood Memory Type: GDDR3 Core Frequency: 550MHz Memory Capacity:

512MB memory bit width: 128bit video memory speed: video memory frequency:

1400mhz

The parameters are in line with the results you see with gpu -z. The one you said should be a DDR5 that should be Shuangmin Fire Whirlwind 2 HD5550 DDR5 V1024 Maverick Edition, with ** differences.

The reference price of the former is 399 yuan, and the reference price of the latter is 479 yuan. If you buy your front graphics card with the ** in the back, then you are deceived. Go complain.

You are fooled, 460 yuan should be the DDDR5 one, and the DDR3 one is only more than 390 yuan. In addition, if you buy a dual-sensitive HD5550 graphics card, there should be no HD5500 graphics chip, if it is indeed an HD5500 graphics chip, then you may have bought a fake.

If you buy it in a place such as a computer city, you can go to the management office of the computer city to complain, and generally these places have a place to accept consumer complaints. But you need to have evidence, such as invoices.

It is DDR3, 4nm process. 512 video memory, 128 bit width. Lvliang Life Network.
