Nowadays, graphics cards are generally good for video memory, bit width, bandwidth, cores, etc

The graphics core is the most important. Responsible for handling all the calculations of the game. The second is the stream processor, each stream processor is like a group, the more groups there are, the higher the corresponding processing efficiency, and the auxiliary GPU is rendered together.

Bandwidth and bit width are not the same. Bandwidth is the amount of data transmitted by the graphics card per unit of time, and bit width is the length of data transmitted by the graphics card. Correct the upstairs.

Bandwidth = bit width x memory frequency 8. You can't change the graphics card as much as you want, you have to measure what level of graphics card is appropriate according to the performance of the CPU. The quality of the CPU can directly affect the performance of the graphics card.

If you want to play large 3D, you need to play it on a graphics card at least 460 or 560. Correct the upstairs again, the 1G 560Ti will explode the video memory at high resolution and high image quality. 560ti must be 2g.

A high-performance graphics card consumes a lot of power, so the power supply is also a factor that must be considered.

Over 30.

Card GTX460 core and above.

3.Bandwidth = bit width x memory frequency.

4.The display core determines the grade of the graphics card.

They are all important, they are mutually reinforcing.

The function of the video memory is to temporarily store the data processed by the GPU in the video memory for the system to call, the larger the bit width, the more bits can be transmitted in a clock cycle, and the memory frequency Memory bit width 8 = memory bandwidth. The greater the bandwidth, the more between the graphics memory and the display chip"Pathways"The wider the data"Run"It will be smoother and will not cause clogging. The higher the memory frequency, the higher the data throughput speed, but if the memory bandwidth is too small, even if the speed is high, the data throughput will not be much, which is basically the same as a multi-lane highway and a single-lane highway.

The core frequency is just the speed at which the GPU processes data, as long as there is no bottleneck between it and the video memory, the type of video memory directly affects the performance of the entire graphics card, such as sports cars and bicycles on the road.

The core bit width of the current mainstream graphics card is 256bit, and this does not need to be mentioned. According to your requirements, I think the suitable models are HD5750, HD4860, and GTS250 and so on. HD5750Although it only has a 128bit memory bit width, it uses GDDR5 particles, so its memory frequency is very high, so the final output memory bandwidth is still larger than that of a 256bit graphics card at the level of GTS250, so 128bit bit width is not a bottleneck at all, so there is no need to worry.

Moreover, the power consumption of HD5750 is very low, and the rated 250W power supply can be used, which is an advantage that GTS250 and HD4860 are definitely not comparable!

HD5750 is now more popular and easy to buy models are Sapphire and Onda, the latter steals the core voltage, so the working frequency has reached the public level of HD5770.

Sapphire HD5750 1G Edition:

Onda HD5750 512M Shengo Edition:

Next, GTS250 is the only choice for N card at 700 900 yuan, and Yingzhong and ZOTAC have a good GTS250 to choose from.

ZOTAC GTS250-512D3 F1:

Yingzhong GTS250 Game Edition:

As for HD4860, of course, it is the strongest performance of the three, using the strongest RV790 core of the HD4800 series and 1GB 256bitGDDR5 particles, although the number of stream processors is only 640, but the performance after a small overclocking is already comparable to the HD4870 GDDR5 version of 800SP. The price is also very reasonable, and it is attractive to gamers who are looking for absolute performance. At present, only the HD4860 of Sapphire is recommended, because its core voltage is the same as HD4890, so you can flash the BIOS to reach the public frequency of HD4890.

Sapphire HD4860 Platinum Edition:

For the LZ you require video memory1GB,I can be responsible for saying that this is chicken ribs,There is no practical meaning,It's really necessary to use up the 1GB video memory capacity to play smoothly,Its requirements for graphics cards are estimated to have reached the level of GTX260+ or above,You choose HD5750 4860 and GTS250 level card core performance is obviously not enough。

In the case that the core, SP, core frequency, memory frequency, video memory speed and other conditions are about the same level, the performance of a graphics card with a high bit width must be stronger than that of a graphics card with a low bit width.

The function of bit width is to transport the channel of the graphics bandwidth, the GPU will store the results in the video memory through the bit width after processing the graphics operation, and then output the display, you can think about it, if the bit width is very low, then the transmission between the GPU and the video memory will be greatly discounted, so that the graphics bandwidth will be insufficient, and the natural picture will be sluggish. On the contrary, if the bit width is high and the video memory is average, it can be compensated for by high-speed exchange of broadband data.

Generally speaking, the core determines the performance, and the core frequency subdivides the core of the same level, and the data processed by the core needs to be throughput through the video memory, so the video memory speed and bit width can also restrict the play of the same level and frequency core (you can't afford to run a sports car in the alley, there must be a highway), it is difficult to explain the relationship.

If you have to choose, of course, it is the core (which high frequency to choose which) video memory bit width video memory size.

The 2 cards you said are basically the same, but the latter has 256 more video memory than the former, so it will be better in theory, please refer to it.

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 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.

Correspondingly, the core bit width refers to the bit width of the interface where the graphics card chip exchanges data with the outside. It doesn't matter which one is more important, they have to restrain each other, of course, the actual performance is low or high, but the graphics card chip is more expensive than the video memory particles, so just look at it, or the core bit width is more important.

But at the current level of the market or technology, we only talk about bit width, and rarely talk about core bit width.

This determines the performance of the graphics card and**.

The graphics card is more important. The second is video memory.

Video card, graphics card, also known as graphics card, is one of the most basic configuration and most important accessories of a computer. As an important part of the computer host, the graphics card is a device for the computer to convert digital-to-analog signals, and undertakes the task of outputting and displaying graphics.

Video memory, also known as frame buffer, is used to store render data that has been processed or will be extracted by the graphics card chip. Like a computer's memory, video memory is the part that is used to store the graphic information to be processed.

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.

Bit width is relatively more important than video memory.

In comparison, 128 bits wide is good, the graphics card mainly depends on the type of video memory, DDR5> DDR4> DDR3> DDR2> DDR, DDR5 is the current mainstream graphics card memory type, and the general graphics card needs DDR3 or above, including D3. The larger the bit width, the better, and 512 is generally enough for the mainstream of video memory. 64-bit wide, 32-bit wide don't think about it, they are all low-end graphics cards.

Between different models, bit width is important. If the video memory is insufficient, you can still eat the memory, and the bit width cannot be changed.

For the same model, it depends on the frequency, and the rendering pipeline.

The bit width can't see anything on the low-end graphics card.,But your 64's is too much.,Now it's generally 256 more points.,Video memory is relatively important.,Now it's generally d3 and d5,D5 is good.,You take that 512 128 to use it.,If it's convenient, it's best to send the model of your graphics card.,Because some graphics graphics cards are really unhappy just looking at the parameters.,But it's not necessarily a good thing.。

If the GPU model is the same (e.g., both GT430) and the memory type is the same (e.g., both GDDR5), the former is better.

Different GPUs cannot be compared, and different memory types cannot be compared.

A k generally refers to the memory bit width The memory bit width is the number of bits that can transmit data in a z l clock cycle 6, the larger the number of bits f the greater the amount of data that can be transmitted in an instante e, which is one of the important parameters of video memory. Memory frequency x memory bit width. 5, then c in the case of the same memory frequency o, the memory bit width will determine the memory bandwidth of the large r small b.

For example, if the same memory frequency is 6600MHz for 156-bit and 742-bit video memory, then the memory bandwidth of n will be 6 for 317 bits 600mhz*648 5=, and 308-bit 500mhz*786 3=, which is 5 times that of 562 bits.

Wide position in front. The second is video memory. Of course, there are DDR numbers in front. Core frequency. It's a process. Many, much more.

Complementing each other, no one is the most important, it should be matched according to the law, generally the bit width is the same as the video memory, or the video memory is greater than the bit width.
