Graphics cards, CAD, laptops!

CAD does not have high requirements for graphics cards as 3D rendering, so these graphics cards are fine. Also pay attention to the problem of dual graphics cards now,Don't be confused,Because win7 can be compatible with integrated graphics cards and independent graphics cards at the same time,This kind of computer is generally more profitable,So it is recommended to buy a computer with only one independent graphics card chip,If there is an integrated chip,You will see 2 chips in the device manager。

It's mainly CPU.,Personally, I recommend using Inter's CPU.,AMD is really bad (although cheap)Inter heat dissipation,Level 2 cache (you will find that AMD is not powerful when you open more tasks)AMD is much better.,AMD is mainly suitable for overclocking players.,And it's cheap.。

And now it's all win7 system, so it's best to have 4G, and 2G is not enough.

For hard disks, if you are doing interior design or civil design and other work, there will be a large number of graphic files, it is recommended to have a minimum of 500g hard disk, if you have any questions, please ask, I hope it will be useful to you.

ps。For the brand problem, if you have money, decisive Apple, IBM or Toshiba, Sony, if the student party, boys will be ASUS, girls will buy Samsung, Samsung's appearance is diverse and more beautiful, and Samsung makes a display, and the screen is better than other brands. Try to choose N card for graphics card, which is the nvidia chip, how to distinguish it, and now the mainstream ones are GTX(X).

CAD 3D graphics rendering requirements, so these cards. It should be noted that there is now a dual graphics card switch, don't be confused, because in win7 compatible integrated graphics card and discrete graphics card at the same time, such as the general profit of the computer, therefore, it is recommended to buy only the computer with a separate graphics card chip, if the integrated chip in the device manager will see two chips.

The main CPU is personally recommended with Inter's CPU, AMD is really bad (AMD is cheap though) between the cooling, the L2 cache (the task is more open will find that it is not awesome AMD) AMD is much better, mainly for overclocking players to use, there is very cheap.

It's a win7 system, and now the memory is the best 4G, and 2G is not enough.

Hard drive, if you do interior design or civil engineering design work, then there will be a lot of graphic files, then it is recommended to have a minimum of 500g hard drive, if you have any questions, please ask, hope it will be useful to you.

ps。If you have money then decisively Apple, IBM, Toshiba, Sony, if the class reunion at that time boy Asus now, girls, then you bought the Samsung brand problem! Samsung's appearance changes are a bit prettier, and the screen of the Samsung monitor is also better than that of other brands.

Try to choose a graphics card with an nvidia chip of an N card, how to distinguish it, the mainstream is GTX (X).

A8 4 core is not cost-effective, it's a lie, it's not as good as i3 dual core (2 generation) CAD is no problem The problem is that SC2 Your 4 notebooks are barely playing Your i3 machine i3 is also a generation of old CPUs, not 2 generations, not 3 generations. In comparison, I'd rather pick 3 at 2000

It will be even lower if it is 2 lots.

To be honest, these four are not very good... I don't think any one of them can completely bring Interstellar 2 up. But you put Interstellar 2 on the lowest allocation.

Then play 1v1 maybe you can play... Now the notebook** is falling very hard.。。 It's not too expensive to buy an i7 plus GTX560 TI book.

Each of these four models can run Auto CAD smoothly. Don't worry about this.

Memory: 512 (the lowest memory configuration of the current book) Graphics card: Integrated graphics card 128m (the lowest configuration of the current book) Processor:

Saiyang above (now it is estimated that you can't buy the antique messy front CPU of the seepage talk) CAD The most popular drawing software, two classic versions (04 version of the computer configuration requirements are ultra-low, my choice) (08 version of the three-dimensional function is more perfect) I have used NEC book (P3 700 memory 256 graphics card: integrated plex touch 32M) Drawing floor plans feels smooth IBMT21 (P31000 memory 512 graphics card: integrated 64M to draw 3D drawings under 100MB feels smooth.

2G memory, mainstream CPU is basically fine. It doesn't have to be a separate graphics card.

In fact, the current computer can basically meet the needs of CAD drawing, but if you want to have a better effect, of course, you still have to have some requirements:

Larger memory: The larger the memory, the smoother the running speed.

Hurry up the CPU: A powerful CPU can drive a powerful graphics card, and the faster the overall speed of the computer.

A professional graphics card is even better: A professional graphics card is especially suitable for high-end CAD drafting and design, and it is obvious when it comes to optimizing and improving the performance of professional software.

CAD drawing software is the most popular CAD software package in the field of computer-aided design (CAD), this software is powerful, easy to use, reasonable, widely used in machinery, construction, home, textile and many other industries at home and abroad, with a large number of user groups.

CAD drafting software has a good user interface and can be operated through interactive menus or command lines. Its multi-document design environment makes it easy for non-computer professionals to learn to use it quickly. In the process of continuous practice, we can better master its various application and development skills, so as to continuously improve work efficiency.

CAD drawing software has a wide range of adaptability, it can run on microcomputers and workstations supported by various operating systems, and supports more than 40 kinds of graphic display devices with a resolution of 320 200 to 2048 1024, as well as more than 30 kinds of digitizers and mice, dozens of plotters and printers, which creates conditions for the popularization of CAD drawing software.

Ordinary CAD drawing does not have high requirements for the computer, but in order to be faster, it is recommended to have a larger memory, choose a processor above the T6 series, a series independent graphics card, and preferably a professional graphics card

There's no special requirement that the mainstream book can run now.,If you want to run more smoothly, the memory should be a little larger, the CPU is slightly better, and there's a separate graphics card.,The landlord is generally used instead of professional.,In fact, now the mainstream book configuration is OK!

64-bit win7 operating system, can't install CAD, helpless!

The graphics card is good, the memory is large, and the CPU can be average.

There are no requirements, the current computer will do.

The GT740M and GT650M graphics cards you said are all entertainment graphics cards, not suitable for your drawing or 3D design, if you want to do these jobs, it is best to choose a model with a professional graphics card, the cheapest is ThinkPad T430, but i3+ independent graphics are more than 5,000, and Dell's is more expensive, such as E6430 is more than 7,000

If it's just two-dimensional,3000More than the book is enough,It's better to draw three-dimensional,It's best5000+,Of course, the independent display is better than the set display,The least heat dissipation is better,ASUS,Acer's book is more cost-effective,Most of our company uses ASUS。

In fact, CAD software does not have high requirements for the graphics card, because functions such as rendering are achieved through the CPU, so your goal with the machine is: high-frequency multi-core CPU, high memory (if it is a 64-bit system, it is equipped with more than 8G memory, if it is a 32-bit system, then 4G is enough, and more systems are not used).

If you want a graphics card to render, then a graphics card for gaming is useless, and if you want to buy a professional graphics card, that's another topic.

Lenovo Y series is good. You can consider it, but it's a bit high.

T420i Note that the concept of running 3D games and 3DCAD software on a laptop is different. If you want to get high performance, you need a computer of at least 10,000 yuan or more to run 3D games. And because of heat dissipation problems, this kind of laptop is generally larger, which violates the original intention of portable notebooks; The notebook runs 3dcad software, and there are no such high requirements.

The popular 3DCAD design software, such as Proe SolidWorks UG, can run laptops with discrete graphics cards. The ThinkPad's T-Series is built for engineering. Under the T420i, there are a lot of sub-configurations.

I took a look, and it's about **7100, and the NVIDIA Quadro NVS 4200M configuration with 1G independent graphics is definitely enough. Other higher configurations, because stronger graphics cards, mean more severe cooling, I don't recommend it. Another benefit of using TinkPad is that it is very stable, the basic software is installed correctly, and it is very difficult to freeze.

It is recommended that you install the 64-bit flagship version of win7,Fill the machine with 16G memory,It's very comfortable to run。 The only bad thing is that the display of this machine is too small, only 14 inches, and the design of future running is a bit stretched. I chose the SL500 a few years ago (independent display + 128M video memory, there is no problem with running PROE), the indicator has 15 inches, and it is very cost-effective.

But now there is no such one. Having said that, whether it's like a notebook or not depends mainly on how often you use it. If you rely on 3dcad software to make a living, then it is best to use a desktop, at the same price, you can be equipped with a very fierce machine; And if you're just studying, or use occasionally, I recommend that you buy ** door level, just enough to run the configuration, it doesn't matter if it's a thinkpad or not (because of this brand, you have to pay at least 1k more).

Anyway, you can't buy only one laptop in this life, a year or two later, the more cost-effective book comes out, and then change it, and get rid of the current half price, maybe the total price is more cost-effective than what you are doing now "in one step". As above, good luck!

I'll draw CAD,First of all, CAD don't use a high version,It's useless,Get a 2012 version is enough,If the budget is less than 5000,Don't draw renderings,That i5 processing is guaranteed to be enough,The minimum memory is 4G,Generally 8G,Graphics card at will,Hard disk is best to choose solid state drive,This processing speed is fast,But the life of the solid state disk is short,It's best to put important files on the mobile hard disk,Or another mechanical hard disk,If you plan to use it for a long time,Match a good point,If it's for learning, Or you don't use a lot of computers, so you can buy a cheaper one, it is recommended to buy a Dell one, but you can draw a CAD very ordinary computer, or you can buy a second-hand one.

Each brand of computer has a better one for drawing, mainly according to the configuration, generally the domestic mainstream better Apple, Lenovo, Asus, dell.

1.Operating system: Windows 7 (64-bit recommended) 2

Video memory of 1G or more, bit width of 256 bit or above, video memory type of DDR3 or above, NVIDIA brand graphics card is recommended (SOLIDWORKS certified professional graphics card is recommended: such as: NVIDIA Quadro series, ATI FireGL series or FirePro series).

Intel dual-core high clock speed 64bit, i5 series or i7 series recommended, CPU frequency higher than recommended, **Processor must support SSE2 (Streaming Simd Extensions 2).

5.Hard disk: not less than 7200 rpm.

6.Software: Office 2007 or 20107Display: Resolution not less than 1400x900.

How about CAD running, and the computer brand has little to do with it, but the notebook is not as convenient as a desktop computer, and now the CAD version is getting higher and higher, the requirements for computer configuration are also high, I personally think that 2007 is the best and most stable, depending on your hobby, I have been using R14 before, stable memory is less, very easy to use, but unfortunately the system is updated to win7, not supported, the next plug-in is also prone to error, mainly others are using 2018, can not be opened, conversion trouble!

It's not about the brand, it's about whether the configuration meets the needs of the mapping. It must be a discrete graphics card, with a video memory of more than 1D, and the latest CPU, it is recommended to choose a desktop-level CPU. There are also good CPU options for choosing a notebook, and the Core i7 is already suitable, with at least 4G of memory, and when these conditions are met, your mapping can be operated.

Choose a notebook don't look at the brand, look at the configuration! Whether it's Lenovo, Asus, Shenzhou, Dell, or HP, Acer. It's all the same to make a computer.

Choose a computer to see the configuration, the best way to design a computer is to use a dual-core single-core to achieve the above, memory more than 2G, hard disk 250-320G can be. I was selling HP at the time, and I just spent money on the brand. The configuration is average, and the sale is expensive.

Recommend the cost-effective Acer base, or Shenzhou, Lenovo. Take your pick.
