Lenovo i3 or i5 pay attention to cost performance, three thousand five to four thousand five, and se

If you want to buy a notebook, I am firmly opposed to the upstairs said to buy Dell, the quality of dell is really rubbish, lie to you is a pig, I have personally experienced, I spent 5000 yuan to buy it before, I still advise you to buy Lenovo, Lenovo is better than dell there.

However, I recommend buying ASUS, because all aspects are good, including heat dissipation, it is a little more expensive, the first floor said that from time to time dell's dog, really angry, the after-sales service is too poor, and bought less than a few days I went to the dell after-sales service there a bunch of people queued up there, and bought less than a few days crashed 3 times, occasionally the screen is flowered, I have a problem with the touch screen, go to them, and the result is to use the software to get me, I want to change no way. It is not recommended to buy this junk goods from the United States. Dell is a Chinese Shenzhou-class computer in the United States.

You still go to the monopoly store according to your own **, and then buy it after you understand, because the notebook is replaced quickly, I can't say, I will know what to buy after learning more, and decide according to your own **.

Lenovo ThinkPad SL410 2842KUC This one is not bad, the screen size is 14 inches, it uses Intel Core 2 dual-core T6670 processor , 2GB memory capacity, dual graphics card switching, there is no problem with entertainment and office, and the performance is relatively stable, the heat dissipation is also excellent, the market price is about 4500 yuan, it is the best choice for students to study online.

Lenovo brand computer front-line family series, Lenovo Qitian business series are economical and durable.

i3 and i5 are the names of the processor families. It is divided into i3 (core 2), i5 (core 4) the first generation 1156 interface, and the second generation 1155 interface (now the mainstream). i5 is the third generation, with more advanced technology and interface 1155 (mainstream).

Buying a whole machine is durable. Personally, I like all kinds of assemblies. The i3 i5 is talking about the CPU model. The performance of the i3 8th generation and i5 7th generation is about the same. The performance of the i3 below the eighth generation is lower than that of the i5 seventh generation. Both are mid-range CPUs.

Lenovo is honestly not economical, if it is durable, it is the ideapad series, and the quality is indeed superior. i3 and i5 are the names of the first, second and third generations of Intel Core processors, respectively positioned in the low-end market and the terminal market, both of the mobile platform are dual-core and four-threaded, and the main frequency gap is not large, but i5 has turbo frequency technology, which can be automatically overclocked according to demand, so the performance is much stronger than the former. The desktop will not be introduced, in addition to the increase in the main frequency, the i5 is also quad-core.

I don't know the first question.,But the second one I can answer.,Now the CPU is generally divided into AMD and i-series.,AMD's needless to say.,It's too complicated.,The best one in the i-series is easy to say.,The best thing to release now should be i7.,That's high-end.,Ordinary people basically don't use i7's,i5 is better than i3 performance.,But presumably it's more expensive in ** i5.,If you want to play large-scale online games, it's recommended to buy i5.。

This year's latest is the core 9th generation series CPU, last year it was 8 generations, 8th generation and 9 bands are not much different, just a slight difference in the main frequency.

But at this stage, there are still 7th generation Core on the market, and the CPU before the 7th generation (including the 7th generation) is one level worse than the 8th generation and 9th generation, that is, the i3 of the 8th generation and 9 bands is equal to the i5 before the 7th generation; Because the CPU after the 8th generation has increased by 50% 100% in terms of specifications, for example, the i3 before the 7th generation is dual-core and 4 threads, and after the 8th generation, the i3 is 4 cores and 4 threads, the i5 before the 7th generation is 4 cores and 4 threads, and the 8th generation i5 is 6 cores and 6 threads.

So the gap between before the 7th generation and after the 8th generation is very large, and the gap between the 8th generation and the 9th generation is very, very small.

How different is the i3 and i5 in my usage habits:

The i3 is dual-core and dual-threaded, and the i5 is dual-core and four-threaded. Your work habits are to use office software, handle emails, and watch movies. For you, it makes no difference. Generally, when using i3 to watch movies and handle emails, the CPU share is less than 40%;

There is also a discrete graphics card and an integrated graphics card HD5000,How big is the difference between 5100:

There is a big difference between a discrete graphics card and a set of graphics, which can be experienced when playing large games, a good independent graphics card can open a better game effect, while a poor graphics card or integrated graphics card is not, and sometimes it will even be very stuck. It doesn't matter if you watch movies, emails, or office software;

And how big is the difference between 2G RAM and 4G RAM:

4G is twice as much as 2G. The speed of a computer is determined by the four major parts: CPU, memory, hard disk, and graphics card. If you are using a card that is too small and is delayed, you need to upgrade to a larger memory;

There is also a trade-off between 32-bit and 64-bit:

A 32-bit system can only perform up to 3G of RAM, while a 64-bit system has no upper limit.

It is currently nine generations, such as i5 9400f, i5 9600k and i7 9700k, i3 only eight generations i3 8100, i3 8350k and the like, in terms of performance, i3 is already four cores and four threads, equivalent to seven generations i5 7400 quad core, but the two are very different, basically no one has a glance at six generations and seven generations.

The difference between the eighth-generation and nineth-generation i5 is very small, it is six cores and six threads, and the performance gap is about 30% compared to the i3.

The eighth-generation i3 has become a quad-core, and the i5 is a six-core. There is still a certain gap.

i3 and i5 are all nine generations, but I heard others say that the cost performance is not high, and the 8th generation i3 and i5 are king.

8 generations. There is a big difference: the 8th generation i5 is better than the 7th generation i7

But at this stage, there are still 7th generation Core on the market, and the CPU before the 7th generation (including the 7th generation) is one level worse than the 8th generation and 9th generation, that is, the i3 of the 8th generation and 9 bands is equal to the i5 before the 7th generation; Because the CPU after the 8th generation has increased by 50% 100% in terms of specifications, for example, the i3 before the 7th generation is dual-core and 4 threads, and after the 8th generation, the i3 is 4 cores and 4 threads, the i5 before the 7th generation is 4 cores and 4 threads, and the 8th generation i5 is 6 cores and 6 threads.

The i3, i5, and i7 have all been out for 5 generations.

The most understandable difference between the i5 and i3 is that the i3 is like a 6-lane highway with a speed limit of 180, and the i5 is like an 8-lane highway with a speed limit of 250. That is, the essential difference in processing speed,So if you run a game, of course, the faster the processing speed, the better,Now i5 and i3** are generally about 500 yuan,But the general game runs up to the performance difference is not felt,But for a higher quality game,There will be a more obvious difference in running speed,That is, the fluency of the game,In general, the difference will not be too big,The processor is an important part of the computer, However, other aspects of the computer can also affect its performance, so this is just a subjective comparison. Pure hand hope to adopt
