Chatting, surfing the Internet, brushing Weibo, listening to music, watching movies and simply playing some games can meet almost all the needs of notebooks, but the problem lies in CAD drawing. First of all, what version of CAD should we know? What level is the drawing? If it is a plan, I will choose the processing of i5, because CAD needs the floating-point operation ability of the processor more. The computer I'm using now is an i3 processor, so it's difficult to open the drawing of CAD2008, let alone draw it.
First, I agree with you. If you buy a better processor, it will run faster and you won't play any big games. There is absolutely no need to spend money on a graphics card.
If the computer with i3 processor is equipped with a good graphics card, it is a relatively abnormal configuration, because no matter what games and files, you have to use the processor before you can run them, and you can't run them with poor processor performance. So what's the use of a good graphics card?
The HP CQ series you mentioned above is a very old machine, and now it is gone. Hewlett-Packard almost no longer produces Compaq models, and now HP is no longer a strong brand in those days.
Dell's price/performance ratio is a bit low, good machines are particularly expensive, and cheap machines work in general, and the heat dissipation is not good. Dell with the same configuration will be more expensive, so Dell is not a particularly good choice. To put it bluntly, after all, you are not a professional user, but a general application. The whole thing is affordable and practical.
Lenovo Z400 series notebooks seem to belong to the category of ultra-thin notebooks, not for home use. The battery cannot be disassembled, and there is no optical drive. After all, we are at home, not for business. Although the CD-ROM drive is of little use now, it is definitely available for home use. What if we want to watch a CD? Housewives, what if they have children at home and watch early education? I have an optical drive, but I don't need it, but I don't have an optical drive. What should I do when I want to use it? The family has a wide range of applications. . And it is mainly used at home. What if it's getting thinner and thinner? You don't wear it every day!
Too much nonsense, let's have something nutritious:
Lenovo G490AT, 3499 yuan, screen 14 inch, processor i5-3230M, memory 4G (maximum support 16G), hard disk 500G, graphics card AMD GT740M independent graphics card, 1G independent memory, HD8570 graphics card performance is average, which is roughly equivalent to. HD8900 is the strongest, HD8800 is stronger, HD8700 and HD8600 are more mainstream, HD8500 is mid-range and HD8400 is entry-level, but this graphics card is more than enough for children and fathers to play League of Legends or something. Some people will say: since the processor is the fourth generation, why choose the third generation? Because four generations are low-voltage and low-power processors, the speed will naturally slow down. Have you ever seen a 2.0 displacement Land Rover, Cayenne and Shepherd? Driving fast is not fuel efficient, and the reason is the same. This processor has a main frequency of 2.6 and a core frequency of 3.2. It must be faster than the fourth generation in actual combat. Of course, it seems a bit immoral for me to compare the first three generations with the last four generations, but I'd rather have a bite of Xiantao than listen to anyone say how the core frequency is, don't you think?
Maybe you will say: it's not bad, but the screen is a little small. After all, you have to draw a picture, so you can see it clearly with a bigger screen.
Then take a look at Lenovo G500AT, the screen 15.6 inches, and the price is 3699 yuan. Same configuration, expensive 200 yuan. Because the screen is large, it is not the same price as the 20-inch monitor and the 2 1 inch monitor.
I won't recommend i3 to you. I3 is not much different from Pentium-class processors. If Pentium can't run the program, i3 may not run either. If i3 can run them, Pentium won't be much slower. Just one more hyper-threading technology than Pentium will cost you more money. If the budget is sufficient, try to buy high-end products, because the speed of upgrading electronic products is too fast, such as QQ and Thunder.
High configuration doesn't mean how fast it will run, but it can guarantee that you will be eliminated at a slower speed unless you plan to get a new computer every year.
