How to distinguish between good and bad master Pay attention to those parameters

First is the core type, then the number of stream processors, then the stream processor frequency, then the core frequency, then the memory frequency and memory bit width, then the graphics card power supply and cooling and interfaces, and finally the memory capacity.

The most important thing about a graphics card is to look at the display chip! The best right now is the GTX295 display chip! The graphics chip can be understood as the graphics processor!

Then look at the video memory (the bigger the better) the type of video memory (the higher the better, now it is generally DDR3, the best is DDR5) and then look at the frequency of the video memory (the higher the better, the higher the type of video memory, the higher the frequency), and also look at the overclocking performance of the graphics card! When purchasing, look at the workmanship and materials are the resistance on it(Generally choose a big manufacturer, the more complex the above things, the better).

Core frequency: The core frequency of the graphics card refers to the working frequency of the display core, and its working frequency can reflect the performance of the display core to a certain extent, but the performance of the graphics card is determined by the core frequency, video memory, pixel pipeline, pixel fill rate, etc., so in the case of different display cores, high core frequency does not mean that the graphics card has strong performance.

Memory frequency: refers to the frequency at which the video is stored when working on the graphics card by default, measured in MHz (megahertz). To a certain extent, the frequency of the video memory reflects the speed of the video memory.

Video memory capacity: is the amount of video memory on the graphics card, which is one of the key parameters for choosing a graphics card. The video memory capacity determines the amount of data stored temporarily in the video memory, and the video memory capacity of the graphics card is 16MB, 32MB, 64MB, and 128MB, and the graphics card with 16MB and 32MB video memory is now relatively rare, and the mainstream products are 64MB and 128MB.

There are also some products that use 256MB video memory capacity, but it should be emphasized that 256MB video memory cannot bring performance improvement in current home applications, which is a little wasteful.

Memory bit width: is the number of bits of data that can be transmitted in a clock cycle, the larger the number of bits, the greater the amount of data that can be transmitted instantly, which is one of the important parameters of video memory.

Memory Clock Cycle: It is the repetition period of the memory clock pulse, which is an important indicator to measure the memory speed. The faster the video memory speed, the larger the amount of data exchanged per unit of time, and the performance of the graphics card will be significantly improved under the same circumstances.

The clock cycle of video memory is generally measured in ns (nanoseconds) and the operating frequency is measured in MHz. The memory clock cycle corresponds to the operating frequency, and the relationship between them is: operating frequency 1 clock cycle 1000.

Then the memory frequency is 166MHz, then its clock cycle is 1 166 1000 6ns.

Hope it helps you thanks for adoption.

The main thing is to look at the main frequency of the CPU, and the brand should also be referenced, after all, it is a brand played by quality.

Generally we use Core.

Whether the interface is complete Whether there is a possibility of upgrading in the next few years Whether the power supply system is complete In fact, the motherboard is bought for stability.

Precautions for DIY installation procurement accessories.

geyin has recently been upgraded from 775 to 1155, and I feel that the following points should be paid attention to1Platform: Intel-1155, New Stable and Reliable Fan: 4 Pin Smart Temperature Control Fan (PWM), energy-saving, noise-reducing, and prolonging fan life radiator fasteners.

Choose a fastener that automatically locks directly on the front without having to disassemble the motherboard for easy maintenance.

3.Motherboard brand:

Choose from the first three lines, ASUS, Gigabyte, and MSI.

The second-tier ZOTAC is also famous.

4.Motherboard display output, at least VGA+DVI dual interface, do not choose the best +HDIM with a single interface

5.Display: There are dual interfaces, VGA+DVI

6.Optical drive: serial port interface, parallel port has been eliminated, and there is no corresponding socket on the new motherboard7Chassis: The thickness of the board is the best, too thin, which is easy to cause deformation of the motherboard and case resonance8Power supply.

Interface specifications, with a separate power interface for 6P graphics card.

Number of interfaces. Intelligent Fan Speed Control (PWM).

Xialu master and other software for performance testing, graphics card performance is one of the most important performance, others can not be paid too much attention as long as they can.
