February 2019 desktop graphics card ladder chart? Performance ladder chart of desktop graphics card in February 2019? Many of my friends don't know yet, so let's take a look at it with the editor.

Ladder chart of desktop graphics card in February 2019

A simplified version of the ladder chart of the graphics card

The same generation architecture graphics card, through parameter comparison, you can easily understand the performance. However, if different generations of graphics cards are compared, it is more difficult to judge just by looking at the parameters. And through the popular graphics card ladder on the network, you can make a very intuitive judgment. The following is the latest version of the desktop computer graphics ladder chart brought by the editor in February 2019.

At present, the graphics card core manufacturers only NVIDIA and AMD, like other Asustek, MSI, Shadowchi, Seven Rainbow, Teso and other manufacturers all belong to OEM manufacturers, using NVIDIA and AMD core memory chips.

For those who buy new computers or newly installed machines, it is generally enough to see the simplified version of the graphics card ladder. This is mainly because, buying graphics cards is generally to buy new rather than old (architecture), mainly depends on the latest one or two generations of products, other old architecture products, basically eliminated, mainly suitable for old computer users for reference.

From the current desktop graphics card market, NVIDIA (N card) product line is relatively richer, and far ahead in the high-end graphics card market, occupying most of the market share. AMD (Ak card) is mainly middle-end and low-end, and because the product line is not particularly comprehensive, so the market share is relatively small.

Prior to this, there are several sayings circulating on the Internet: "A card color is good, N card speed is fast"; "A card drawing is good, N card game is good". But these statements are actually several years ago, now, N card and A card there is little difference, ordinary users do not need to come out of the difference. However, because NVIDIA graphics cards occupy the mainstream of the market, there are relatively more advantages in technology, N cards consume less power than A cards, and because there are more manufacturers, optimization is relatively better, while A cards are more cost-effective than N cards.

Second, how does the graphics card look good or bad?

As the core hardware of the computer, graphics cards are mainly related to display, especially in games and video rendering scenes. The reason why these scenes consume graphics cards, mainly because the display screen is more complex, and is dynamic, of course, the requirements of the graphics card is high.

So, how do desktop graphics cards look good or bad? In general, we mainly look at these graphics card parameters.

1. Architecture

Whether it is CPU or graphics card, the impact of architecture on it is enormous. Put aside the architecture to see the video memory, main frequency, bit width, etc., are playing hooligans. Generally speaking, with the continuous progress of science and technology, the graphics card architecture will continue to evolve. New architecture graphics cards tend to bring more efficient performance, accompanied by reduced power consumption and the use of more new technologies, so as to effectively enhance the user experience.

Take NVIDIA graphics card as an example, the new generation of RTX20 series, Turing (Turing) architecture graphics card, compared with the previous generation of GTX series Pascal (Perth) architecture of the same level graphics card, the performance has been greatly improved. For example, compared with the previous generation of GTX1060, the overall performance of RTX2060 is improved by up to 60%, and there is a significant gap between RTX ray tracing and new technology support of DLSS.

In popular terms, architecture is the technology used by graphics cards. Generally speaking, the newer the architecture of the new generation of graphics cards, the stronger the computing power, just like the difference between the old car engine and the new engine, fuel saving and better performance. So in principle, graphics cards are recommended to buy new rather than old.

2. Stream processor

Stream processor referred to as SP, also known as render tube, is one of the most important parameters of the video card. The number of stream processors directly affects the performance of the video card. The more the number of stream processors, the stronger the drawing ability of the graphics card and the faster the speed.

3. Video memory capacity

Video memory can provide temporary storage function. Many profiteers will use video storage as the selling point of graphics cards to fool rookies. What I want to say here is that big memory is useful, but it is not so important, the structure is not good, and no matter how big it is, it will play hooligans.

For example: video memory is a parking lot, if the road of the parking lot is not wide enough (bit width bit) and the speed of the car is not fast enough (video memory frequency MHz), then the throughput of this parking lot is very small, and it is a waste of resources to build a super-large parking lot.

4. Video memory frequency and bandwidth

The higher the frequency, the stronger the performance, the greater the heating, the higher the power consumption; the lower the frequency, the weaker the performance, the smaller the heating. The same is true of the explicit memory bit width, the following is a formula for calculating the video memory bandwidth

Video memory bandwidth: video memory bandwidth = video memory bit width × video memory frequency

We can compare the apparent memory width to the highway. The wider the road is, the more vehicles can pass at one time. We compare the video memory frequency to the speed of the car. The faster the frequency, the faster the data transmission. Therefore, the bit width and memory frequency of the video card also have a great impact on the performance of the video card.

These are the core parameters that determine the performance of the graphics card. Theoretically, the larger the stream processor, the capacity, the frequency and bandwidth of video memory, the better. However, the performance of graphics cards can not only look at these parameters, but also need to be considered in combination with architecture. Only graphics cards of the same generation make sense, while products of different architectures (different generations) are more complex.
