Whether the graphics card is better with more stream processors or with more onboard video memory

GT should be called shaders, the more the merrier.

2. The wider the memory bit width and the higher the frequency, the better.

3. The faster the memory frequency, the better.

4. The faster the core frequency, the better.

First of all, the number of stream processors of A card and N card cannot be directly compared, and the architecture of the two is different.

From the chip point of view, in fact, the performance of 9600GT is better, but normally speaking, the ** of 9600GT is 100 200 yuan higher than HD4670.

Your HD4670 is also a shrunken version,If you want to buy HD4670 Thunder Drill that recommends Dilan Hengjin,Don't buy any miscellaneous brands,9600GT is the same now, there are a lot of fakes in graphics cards。

Of course, the 9600GT performs well. The stream processor of the A card divided by the stream processor of the 5=n card is basically compared in this way. In fact, the more stream processors, the greater the performance improvement, almost linearly.

For a graphics card like the 4670, 512MB of video memory is the most, and even if you use 1G, it has the same performance as 512MB.

The latter,Reason:Your Core 4-core machine is equipped with a 128M memory,You can 44Just look at the effect,

800 A cards are about equal to 128 N cards.

If you don't understand, just look at the model, choose the best HD5970 cost-effective GTX460 or the low-end 4850 5770 subclass is cheaper than GT240 or 4750 subclass.

It's all important, stream processing is more important, the stream processor is like a porter in a moving company, the memory bandwidth is the width of the stairs and the height of the floor, of course, the more workers, the more important it is, of course, the number of goods to be moved, which is why sometimes low-end games, low-end graphics cards are better than high-end graphics cards, and another point is not that the memory bit width is good, but also consider the speed of video memory, for example, dd5 128-bit width is much faster than DDR2 512-bit wide graphics cards.

The stream processor directly maps the multi-graph data stream to the stream processor for processing, and there are two types: programmable and non-programmable. The stream processor can optimize the shader engine more efficiently, it can process stream data, and also output a stream data, this stream data can be applied to other superscalar stream processors (SPS), stream processors can run in groups or large numbers, thus greatly improving the parallel processing capacity.

How many stream processors have a decisive role in the performance of the graphics card, it can be said that the most important difference between the high, medium and low-end graphics cards in addition to the different cores is the number of stream processors, but one thing to note is that the number of NV and AMD's graphics card stream processors is not comparable, the core architecture of the graphics card of the two of them is different, and the performance cannot be seen by comparing the number of stream processors, under normal circumstances, the number of NV graphics card stream processors will be significantly less than AMD, and the performance should be seen from the number of stream processors, which can only be compared with their own own.

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. In the same level of chips, the higher the core frequency is more powerful, and increasing the core frequency is one of the ways to overclock the graphics card. Under the same graphics core, some manufacturers will appropriately increase the display core frequency of their products to work at a frequency higher than the fixed frequency of the display core to achieve higher performance.

Graphics card bit width: refers to the memory bit width, that 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 in an instant.

Stream Processor: It processes the data transmitted by the CPU, and converts it into a digital signal that can be recognized by the display, which plays a decisive role in the performance of the graphics card.

Importance: Stream Processor Bit Width Video Memory, this ranking is only for these three indicators, in fact, they are also the three most important indicators that affect the performance of the graphics card, all of which are indispensable, any one of which is too poor will drag down the overall performance of the graphics card.

Of these parameters, video memory is the least important.

The first thing to look at is what architecture the GPU of this graphics card is and what chip is used. This is the most noteworthy. Only on the premise of better cores, then look at his comprehensive look at the core frequency, stream processor and bit width.

These 3 parameters can't just say which one is the most important, you must look at it comprehensively, the best example is HD7770 and HD6850There are also GTX660 and GTX560, which are graphics cards with bit width. Stream processors all have their own merits, and you can't say that which one is good is necessarily better.

It is still necessary to integrate all aspects of analysis.

So, if you're a newbie. Don't worry about any other parameters. Generally, you can't analyze it, just look at what his core is. And then how much money you can buy, you can buy the right graphics card. The principle that you get what you pay for is the same.

The GT740M is much stronger than the GT620M. Although the GT740M has a bit width of only 64, the core is much stronger than that of the GT620M. It is also much stronger in terms of performance.

At present, the graphics card with the most stream processors is GTX Titan X, and the stream processing capacity is 3072, which is the most graphics card at present

Stream processors: 3072.

Hehe, you haven't studied it carefully.

The R&D team of A card is countless times behind that of N card.

Someone has counted that the capacity of the stream processor of 6 A cards can be close to that of one N card.

Therefore, a card of the same level needs a lot of stream processors to achieve the capacity of the n card, and of course, the power consumption and heat generation are also large.

The classification of N cards is very clear, GS is the mobile version of GT, that is, the shrinkage version, which is used on mobile platforms such as notebooks, because the computing requirements of this type of platform are lower than those of the same desktop, so it is understandable that the shrinkage will be reduced, of course, ** will also be reduced.

The number of stream processors determines the computing speed of the graphics card, but it does not determine the computing power, the bit width determines the output speed, and the video memory determines the upper limit of computing GPU is responsible for computing and coordination The driver is responsible for connecting with the system Driver update is also important... Wait, the graphics card is the same as the black computer, and it's quite complicated.

That's the relationship.

It also depends on other parameters, such as bit width, frequency, etc.
