Low computing power of 4G graphics card
if you can connect 4G on your graphics card, all you can think of is the memory capacity
the performance of the graphics card is mainly determined by the GPU of the graphics card, and the memory capacity does not fundamentally affect the performance of the graphics card
when mining, the computing power of the graphics card is completely determined by the GPU. If the computing power is very low, it only means that your graphics card is too low-end and poor performance.
the performance of graphics card mainly depends on its core. The core determines whether the performance of the graphics card is strong and whether the score is high.
The difference between 4G graphics card and 2G graphics card is as follows:
1. Different graphics memory of graphics card
Second, the rendering ability of image is different.
1. 4GB graphics card: the rendering ability of 4GB graphics card is stronger, because the ability of video memory directly determines the clarity of the image. The clearer the image is displayed, the stronger the ability of image rendering
2. 2GB graphics card: the image rendering ability of 2GB graphics card is relatively weak, and the clarity of image display is relatively general. The graphics card with 2GB image rendering ability is often used in ordinary home computers Second, different prices1. 4GB graphics card: the price of 4GB graphics card is very high, because the higher the value of graphics memory, the stronger the performance of graphics card, and the more expensive the sales price is, and the general price is more than 2000 yuan
2. 2GB graphics card: the price of 2GB graphics card is relatively cheap, because this kind of graphics card is for the general public, so the sales price will be lower, generally around 1000 yuanthe display chip is the heart of the graphics card, the first thing to consider is the type of display chip. With the increasingly fierce competition, there are more and more brands and types of display chips, and everyone has different choices of other accessories. Considering the coordination of various accessories, it really takes a little effort to choose a satisfactory graphics card. After determining the display chip, we should also consider the following factors<

type and capacity of video memory
the type and capacity of video memory determine the performance of video card to a great extent, which is directly related to the maximum resolution and color depth supported by the video card, and also closely related to the 3D processing speed of the video card. More and more video memory is the trend of video card development. At present, more and more graphics cards use DDR memory, especially high-end graphics cards, such as geforce4gts, radium standard edition, etc., which makes the performance of graphics cards develop rapidly<

interface type
nowadays, the PCI interface graphics card has disappeared in the market, and the graphics card interface has been unified as AGP bus

pay attention to identify fake procts
now there are many specifications of various display chips, which provides convenience for JS counterfeiting. Many JS often mix beads and use low-grade graphics cards as high-grade graphics cards. We must pay attention to identify fake goods when purchasing. It's better not to buy miscellaneous brand procts with too low price. Moreover, if you buy procts from famous brands, even if the price is slightly higher, you'd better go to the agent to buy them.
2. For the performance of a graphics card, not only the parameters of the video memory, but also the core performance and frequency of the video memory are very important; Take n card as an example, the performance of gtx1060 3G is better than gtx1050ti 4G, and the price of 1060 3G is several hundred yuan higher than 1050ti; If both laptops are equipped with NVIDIA's independent graphics card, the performance of 4GB 1050ti is certainly not as good as that of 6GB 1060. Besides the size of the video memory, this is more e to the performance difference of the core of the graphics card
3. According to the 3D mark running scores, the running scores of GTX 1050ti and 1060 in time spy and extreme are 2344, 4085, 3725 and 6161 respectively, with a big gap
in theory, more memory is better. The larger the memory capacity, the smoother the computer speed. 6G must be better
but the feeling of actual use depends on the situation
1. Ordinary home users: 4GB of memory is enough. 4 and 6G feel almost the same
2. Game enthusiasts: at present, the biggest demand for games' memory is 6GB. Therefore, 4G memory games can't get in, and 6G has obvious advantages
3. Video and animation procers: 8g is a bit low, so more memory is better. 6G is obviously better than 4G.
You can't answer this question
because: how many GB of video memory capacity is just one of the specifications of many graphics cards, it is far from representing the performance level of a graphics card . Mainly depends on the graphics card GPU model
for example, someone asked: what grade of car is equipped with leather seats? This is also unanswerable. Because millions of Porsche 911 can be equipped with leather seats, and Chery QQ can also be equipped with leather seats
similarly, the entry-level graphics card of gt610 level can be equipped with 4GB of video memory, and the medium and high-end graphics card of gtx1060 level can also be equipped, but the performance of the latter is several times that of the former
in recent years, e to the correlation between the performance level of the graphics card and the capacity of the graphics memory, unscrupulous merchants intentionally or unintentionally ignore the model and specification of the GPU core of the graphics card, and only use the size of the graphics memory capacity to deceive ordinary people who do not know computer knowledge. The most commonly used trick is to use a low-end graphics card with a huge capacity of video memory to fake a high-end graphics card and sell it at a high price to earn money. Two or three hundred yuan of 4G garbage card pretends to be thousands of yuan of 4G high-end card, and one card can make more than 100% profit at most. Marx said that with such high profits, capitalists can wage war. Originally, now a normal computer can only earn one or two hundred yuan, such a flicker, installing one is equivalent to installing several
now that you have asked this question, you need to say something more: you should learn to pay attention to the model and physical specifications of the graphics card core (GPU chip) -- GPU architecture, number of stream processors (the most important), memory bit width, core frequency, memory frequency, memory type (GDDR3 or gddr5), DX special effect level supported, etc, It's OK to read more horizontal comparison and evaluation articles of graphics card to understand the dynamic development of graphics card technology
the performance of the graphics card is not determined by the memory, but mainly by the GPU
so you can compare their parameters in general<
gtx660 GPU specification:
CUDA processor core: 960
drawing frequency (MHz): 980
texture filling rate (bill / sec): 78.4
gtx650 GPU specification
CUDA processor core: 384
drawing frequency (MHz): 1058
texture filling rate (bill / sec): 33.9
CUDA processor core is equivalent to whether CPU is single core or multi-core, The more CUDA cores there are, the stronger the computing power of GPU will be. When the drawing frequency of 660 and 650 is similar, the former has more than twice the number of CUDA cores, and the texture filling speed is more than twice as fast as the latter. 3D scenes are made up of textures. The feature of 3D games is that the scene changes again and again. The faster the texture filling speed is, the faster the scene is generated, and the higher the number of frames, The more fluid it is
the video memory is only used to store the data to be processed and the processed data of the GPU. As long as the size can meet the needs of the GPU, more is wasted and meaningless.
Video memory, also known as frame buffer, is used to store rendering data processed or to be extracted by the graphics chip. In addition to the type, bit width and bandwidth of video memory, the capacity of video memory is also an important parameter of video card. The size of the graphics memory determines the actual game performance of the graphics card to a certain extent. Especially for most of the high-quality large-scale games in recent two years, a large number of exquisite game maps have higher and higher requirements for the graphics memory
In late January last year, NVIDIA released geforcegtx960, a second-generation Maxwell architecture dessert level graphics card, which is equipped with 2GB gddr5 memory. Because the video memory capacity is still 2GB, and the bit width is only 128bit, it has been criticized by players. In June last year, amd also released its new sweet spot card, radon r9380. With its high specification, high performance and 4GB video memory, the card has become an insurmountable rival for gtx960. In August of the same year, NVIDIA began to sell the 4GB version of gtx960 on a large scale and graally cleared the inventory of 2GB version in order to meet r9380 equally The launch of gtx960 with 4GB video memory indicates that medium and high-end video cards are finally stepping into the era of 4GB video memory. After that, 4GB will become the entry capacity level of medium and high-end video memory. I remember that the last generation of flagship gtx780 and gtx780ti only had 3gb video memory, while this generation of midrange sweet grade video cards have begun to popularize 4GB video memory in a large area, which makes people doubt whether this kind of video memory upgrade is meaningful. Is it just the manufacturers piling up hardware to promote the performance of video cards? Do you really need such a large amount of memory to ensure that the graphics card can work perfectly With the development of the times, the size of the display is larger and larger, the corresponding resolution is also higher and higher, people's demand for fine image quality brought by high resolution is increasing. Although the current mainstream resolution is still 1080p, 2K or even 4K resolution displays have been recognized by many people. Even the palm size mobile phone screen has reached 4K resolution. Higher resolution naturally has higher requirements for video memory. It is generally believed that 4GB video memory is the minimum requirement for large-scale games at 4K resolution. In order to boast that their video cards can support 4K resolution, manufacturers will increase the capacity of video memory to more than 4GB in order to better cope with high resolutionquadrom6000 with 24GB video memory
What's the difference between 4GB video memory and 2GB video memory? Is it true that the larger the video memory, the better? Facts speak louder than words. Next, let's see how 2GB version of gtx960 and 4GB version of gtx960 perform differently in theoretical performance test and game performance test at the same frequency
fan design of graphics card
in terms of heat dissipation, MSI gtx960 gaming is equipped with twinfrozrv heat dissipation system which has been applied to gaming Series graphics cards since gtx980. The graphics card is equipped with two third-generation blade fans with a diameter of 10cm, which not only supports PWM speed regulation, but also provides greater air volume than traditional fans, and makes the air pressure more concentrated, so as to better let the air take away the heat from the fins. In addition, the twinfrozrv cooling system of the video card also uses the zerofrozr technology. When the temperature of the video card is lower than 60 ℃, the two fans will be in the state of stop or alternate operation, which greatly reces the noise of the video card under low load
Design of graphics card radiator
the heat dissipation system of MSI gtx960gaming has three pure copper nickel plated heat pipes, two of which are S-shaped 6mm heat pipes and the other is U-shaped 8mm heat pipes, which are evenly distributed in the whole fin array and connected with the heat dissipation fins through welding process. The cooling base is also polished by nickel plating, which can be more closely attached to the core of the graphics card to achieve better cooling effect
In order to improve the service life of the graphics card, MSI gtx960 gaming has also installed a fixed protection board on the graphics card, which has the same heat dissipation and PCB reinforcement effect as other brands of backplaneMy price is lower than yours
The difference between 2G graphics card and 4G graphics card is that both 2G and 4G are video memory capacity, and the most obvious difference between them is the size of video memory
generally speaking, the main impact of 2G and 4G video memory on users is that games, especially large-scale 3D stand-alone games, need high configuration, graphics card configuration and video memory capacity
now I need to explain to the owner that when identifying a graphics card, the most important thing is the model of the graphics card. For example, NVIDIA's seven generation gtx780 and nine generation gtx950
at this time, if the 780's video memory is 2G and the 950's video memory is 4G, the result is that the 780's performance is 2-3 times that of the 950's, so when selecting a video card, the most important thing is the performance and model of the video card, not its video memory
There is a big difference between 2G graphics card and 4G graphics card:
1. It is not big. If the graphics card of the same model has a larger memory capacity, it will have some small advantages
2. For different types of graphics cards, there is no need for video memory, because the mainstream video memory on the market is generally 2G, which is enough to meet almost all the requirements of users
note: when purchasing a computer or graphics card, people who know computer knowledge can make suggestions
