Which is better, 1G physical memory or 2G independent graphics?

On the basis of sufficient video memory capacity, the size has no impact on performance. The impact on performance is the GPU and video memory bit width, and the former you mentioned has strong performance. For GPUs of this level, not to mention 1G video memory, 512M is enough.

First of all, the resolution of the notebook is low enough, and the memory is not so high at all, and secondly, this low-performance GPU performance cannot meet the large video memory processing, simply put, when you need to use 512M video memory, the GPU is already overwhelmed and the card is bursting. You must know that new games such as Battlefield 3 and Mission 9 have full special effects at 1920*1080 resolution, 8AA, and the video memory is just enough to explode 1G, occupying about 1100M. Not to mention lowering the resolution and reducing the special effects, just reduce the anti-aliasing to 4AA, and the video memory occupation will drop to 900M.

Even if GTX650Ti or ATI 7770, 6850 and other desktop mid-range graphics cards of 800-1000 yuan 1G video memory are enough to use, more is a waste of money. Those entry-level 1G, 2G are pure pit money. What's more, the performance of mobile graphics on laptops is lower than that of desktops.

ASUS's comparatively well.

Integrated graphics card: The video memory uses a part of the memory, making the memory smaller, and the independent graphics card: has its own video memory, which does not affect the memory when running.

The integrated graphics card will share the system memory to make its own video memory, while the discrete graphics card will have its own independent video memory. The GT620 you see should be 1G DDR5 memory, while the GT610 should be 2G DDR3 memory, and these two cards are definitely 620 better than 610. The quality of a graphics card is more about its bit width, frequency, stream processor and other parameters, rather than judging the graphics card only by the memory capacity, on the contrary, the mainstream graphics cards are now 1G DDR5 video memory, so the memory size has become the least important parameter.

It's good to be alone.

Discrete graphics card is to make the display chip and related components into a board independent of the computer motherboard, which becomes a professional image processing.

Hardware devices. Its performance is far superior to that of on-board graphics cards, not only can be used for general work, but also has a perfect 2D effect and a strong 3D level, so it is often used in desktops and laptops, and the interface forms of discrete graphics cards applied to desktops are AGP and PCI-E.

Introduction

Discrete graphics cards are further divided into built-in discrete graphics cards and external graphics cards. The discrete graphics cards we usually see are built-in discrete graphics cards, which are plugged into the AGP or PCI-E slots of the motherboard.

There are two kinds of built-in discrete graphics cards, pure discrete graphics cards and hybrid graphics cards, the former is needless to say, it is an ordinary graphics card, and the latter is that the graphics card has its own video memory and at the same time can call the system memory through the system bus to increase the video memory capacity, typical Turbo Cache technology developed by NVIDIA and Hyper Memeroy technology of ATI can do this.

Which is better, independent display or set display?

1. What is the core (GPU) of the graphics card, but those that can be equipped with 2G video memory are generally high-end cards.

2. Video memory type. At present, the popular types of video memory are DDR3 and DDR5, DDR4 is relatively rare.

Discrete graphics card: Discrete graphics card, referred to as independent graphics card, is called independent graphics card in Hong Kong, Macao and Taiwan, which refers to an independent board and a graphics card that needs to be inserted into the corresponding interface of the motherboard, generally a PCI-E X16 interface. Discrete graphics cards are divided into built-in discrete graphics cards and external graphics cards.

The difference between the working frequency and the running speed, the difference between the delivery speed and the memory capacity.

1.The difference between the operating frequency and the speed of operation.

The memory type refers to the parameters such as GDDR3 or GDDR5 marked on the product label. This can be simply understood as the working frequency of the video memory, GDDR3 generally refers to the working frequency of the video memory is 3000MHz, and the working frequency of GDDR5 is 5000MHz.

In other words, GDDR5 is twice as fast as GDDR3, so GDDR5 memory with 1G capacity is not necessarily slower than GDDR3 with 2G memory.

2.The difference between fast and slow conveying.

The memory bit width refers to the number of bits of data that can be transmitted by the memory in a clock cycle, the larger the number of bits, the larger the amount of data that can be transmitted instantaneously, and vice versa.

For example, a 1G graphics card, its bit width is 128 bits, and a 2 GB video memory bit width is 64 bits, and the amount of data that video memory can provide to the core at one time is 2G x 64bit = 128GB of data. Therefore, when other parameters are the same, the speed of 1G and 2G is the same.

3.The difference in memory capacity.

Video memory capacity, which is what we often refer to as 1G independent graphics or 2G independent graphics cards. In the case that the above two parameters are the same, a 2G independent display is naturally better than a 1G independent display.

Watching dramas, listening to songs, and playing small games are enough, but playing professional large games is not enough.

If it is used for business office, entertainment, watching dramas, listening to songs and browsing the web, the 2G independent display is enough and more than enough; If it is used to play small games, a 2G independent display can also be used; If you are a professional enthusiast gamer, a 2G GPU will not be enough because it cannot be considered a high-end graphics card.

Introduction of 2G independent display:

2G graphics card means that the laptop uses a discrete graphics card, and the video memory of the graphics card is 2G. Discrete graphics cards are divided into built-in discrete graphics cards and external graphics cards. Usually, the 2G independent graphics card that appears when we buy a computer is generally a built-in discrete graphics card.

Introduction to discrete graphics cards:

A discrete graphics card is a display chip and related devices made into a board independent of the computer motherboard, becoming a professional image processing hardware device. Its performance is far superior to that of an onboard graphics card. Its performance is far superior to that of onboard graphics cards, and it can be used not only for general work, but also for perfect 2D effects and strong 3D levels.
