What is the difference between I3 and I5? Which is better to buy, Acer 4750 or Lenovo Y470?

If you play games, you want a good graphics card, and that graphics card is good to buy that.

It can be said that the most important time to need computer performance in daily life is when playing large-scale 3D games, usually work, install files or something, the performance requirements for the computer are not high, the CPU usage rate is generally below 30%, and in the case of the same graphics card, i5 is better than i3 one frame or two frames, can not be drawn.

The performance of the i3 is about 20% worse than that of the i5, if you don't play games, I recommend the i5 Acer 4750 (and it is cheap), and the Y470 is recommended for gaming

In terms of cost performance, the Acer 4750 is much higher, and in terms of practical application, the i3 and i5 are not much different.

I don't think there's much difference between i3 and i5,There is a gap in price,Although we won't involve any advanced functions in actual use,But I still feel that i5 is strong,Professionals have their own choice。

Acer's computer hasn't been used much, I think the two computers are mainly different from the graphics card, Lenovo's is stronger, and it's 2G video memory.

Graphics: GT555> GT445> GT550M > HD 6570M HD 5730 GT 540M > GT 435M > HD 6550M > HD 5650 > GT 425M

I don't think you can play any strong games at this price.,Go to the physical store yourself.,Feel the feeling and appearance of the two machines.,If you don't think about a lot of games.,Look at the feeling and choose one.,The game is more consideredY470.。

Hello, the two CPUs you mentioned are dual-core and four-threaded, and the core architecture is the same, which means that the CPUs are interchangeable. The difference is that the i5 has a higher clock speed and its turbo technology can reach a higher maximum value, which is faster and more efficient when running single-threaded operations.

The graphics cards are 540 and 550 respectivelyIt's already a very good configuration for a notebook,In general, I think Acer is more cost-effective,But Lenovo's after-sales service is more perfect,How to choose is still up to you。

i3 and i5 don't really need to worry about it, the current CPU is generally excessive, the graphics card can't keep up, and the CPU is useless no matter how high it is. These two are nothing more than ** problems, if you have less money to buy 4750, if you have more money, I won't buy a small y. It's too ugly, it's better to buy an Acer 4830.

The i3 is not much different from the i5, and the i5 will be better in terms of performance.

It is recommended to buy Lenovo Y470

The gap is not very big, one will overclock by itself, the other is manual, and the cost performance is higher than that of Lenovo. It mainly depends on how you use your computer.

1: i5 is higher than i3. The actual performance is just a little bit higher.

2: Acer 4750 is more worth buying!

Not much worse than the Y470's configuration is a little better.

I hesitated at the time, but now I've got the 4750. The reason is simple: it is much more affordable to do this in a down-to-earth manner than to advertise itself as an international brand.

Hello, the difference between the two versions of the Lenovo Z470 series is:Z470A-IFI(U) uses the second generation of intelligent Intel Core i5 processor i5-2450M(,Can turbo frequency acceleration to,4G memory,** 4999 yuan.

Z470A-ITH(U)( 2nd Generation Intel Core i3 Processor i3-2350M(,2G Memory,**4599Ԫ.)

Other configurations, both books are the same.

I've also taken a fancy to this, and I'm going to take it in the next two days, and I'm also struggling with which one to want

Lenovo notebook Y series was originally focused on games, but your processor is i3 is indeed a bit behind.

1.If you want to play games, you can change it.,You need to know if the CPU on your motherboard is [soldered] up.,Don't think about soldering.。 Generally speaking, [AMD] notebook DIY is better, [Inter] is very difficult, and it is better to buy a new one to change the CPU, because the computer performance is [comprehensive], and it is necessary to consider many elements [slot type, core code, bus frequency, core voltage and other technical factors, etc., but also need to consider heat dissipation, motherboard BIOS and other factors], these are all satisfied, so there may be some [incompatible] problems between hardware after changing, Unless you can find the configuration that matches your original (difficult to find), and the price is also a bit expensive, and the performance improvement it brings is also very limited, if you want to change, go to the after-sales department to consult before replacement.

2.If you don't change it, you can turn off all the game effects, lower the resolution, and your native graphics card is a dedicated display, which is no problem for the smooth operation of the current general game.

In short, if the CPU affects your normal use, change it, but be mentally prepared, and the original one is the most compatible, and it will be used if it doesn't affect it. The landlord thinks a lot.

Personal humble opinion, there is a wrong hope to point out.

i5 has an acceleration function.

That is, automatic overclocking, up to the most.

Without accelerating.

That is, in two CPUs

All work in the case.

Performance is the same if.

i5460 speeded up.

Then his performance will be much more than that of the i3.

About eleven percent.

Actually, i system cpu

The kernel architecture is all the same.

Difference Between i3 and i5:

Only in the internal instructions.

To the cache size.

You don't have to think about it here, because the i3 is not small, even if it is big.

The performance improvement is also not significant.

To compare i5 and i3

Just look at the highest clock speed.

The CPU can be upgraded, but the impact is not very large, mainly due to the limitations of the graphics card itself, the game frame is not, it is recommended to lower the game image quality.

Hello, if you need to upgrade your hardware to play a large game, you won't have the problems you mentioned above after the hardware upgrade, I hope it will help you.

Dear users, hello!

This is the Lenovo FAQ knowledge base, which has a relatively complete answer and know the process and analysis:

Y470Since you have chosen this, it must be to find the difference on the CPU.

The graphics cards are all high-end graphics cards in GT550M notebooks, and most of the memory is 4G.

Take it according to your needs, and tell you the difference between i3 and i5.

The Y470 uses the second generation of the latest i-series SNB U.

Both i3 and i5 are dual-core four-threaded, and the meaning of this four-thread is that when necessary, multi-threaded tasks can be closer to four-core U, but they can't catch up.

The advantage of the i5 over the i3 is that it has a turbo boost. This thing is to increase the clock speed when necessary.

Laptop devices and desktops cannot be compared side-by-side. For example, the i-series U of the notebook generally defaults to the main frequency around the left, and the i3 is also this frequency no matter how you use it, and the i5 can increase the frequency when needed, which involves a maximum turbo frequency.

If you're just chatting online, entertaining, and doing general work, i3 is enough.

If you want to play some high-end games and use some relatively high office software, i5 is recommended, and i5 is enough for games.

As for i7, the necessity is not very large, mainly because some multi-threaded multi-** software is more cost-effective.

Overall, Y470 is relatively popular today, and there has been a price reduction recently, and the cost performance of all aspects of configuration is quite high at this price.

Also, take a look at the Asus N43 53 i5 GT550M, the same configuration.

See what? And how much money do you have? If you have money, you can buy i5, and if you don't have money, you can buy i3

Fifty-fifty.

It is recommended to look at the graphics card.

Which graphics card is better to buy that.

Bro trust me, buy i5! The i5 is an enhanced version of the i3 with a big improvement in terms of structural assumptions and processing speed! If you don't play any big games, in fact, i3 is more than enough to use, I will now use Lenovo Y460i3 processor, two G of memory, I also want to be a stick!

This varies from person to person,,Under normal circumstances, there will be no difference between the two in the process of use,If you often do large-scale graphics processing and computing,Just choose i5,The rest are about the same,Oh,That's right,i5's can be core acceleration,But heat dissipation is more difficult,

i3 I'm experiencing some lag with the recommended i5

Both of these are very good, what to do specifically.

1. If it is for business use: buy ThinkPad Of course, it should not be the SL series, the ThinkPad T series and the X series of computers are very good and suitable for commercial use, stable and durable.

Second, the Acer computer configuration is higher, more suitable for audio-visual entertainment, and the relative durability is definitely not as good as Thinkpad.

Third, the first is heat dissipation, Acer feels that playing games is hot, and E420 is hot when playing. Performance, E420 6630 graphics card, COD8 and Battlefield 3 do not open full effect smooth operation. Finally, the brand, Acer is abroad, equivalent to the domestic Shenzhou, and TP is domineering, the little red dot is very easy to use in class, no need to bring a mouse.

Fourth, if it's a game, it depends on the game, in fact, the difference between i3 and i5 is an overclocking (turbo acceleration), that is, the third generation i5, it is said that it uses different nanotechnology, in fact, the difference is not very big, but now i5 is the mainstream, and it will not be eliminated soon after buying i5, and then look at the graphics card.

Personally, I recommend Acer, which is cost-effective and configurable, worthy of your money.

ThinkPad is indeed good, but what are you used for?

Are you more for business or for gaming?

Buy ThinkPad for business use, of course, not the SL series, ThinkPad T series X series computers are very good, very suitable for business, stable and durable.

Acer computers are more equipped with higher configurations, which are more suitable for audio-visual entertainment, and the relatively durable type is definitely not as good as the ThinkPad

I recommend using Acer, and my colleagues and friends use a lot of it.
