What processor to choose between an Intel Core i3, i5 and i7?

5:36 pm January 3, 20178974HOW TO

a lot of us wondered which processor choose for your laptop or desktop among all these Intel processors. Despite the years, some users are still struggling to compare the Core i3, i5, and i7 processors between them. I therefore propose a small guide that will allow you to compare and choose for yourself Core processors that best match your needs.

compare yourself the Core i3, i5 and i7 performance

as we tend to believe at first, a Core i7 does not have 7 hearts any more than a Core i3 for 3 hearts. The numbers are simply a code of the processing power of the CPU .

you probably know: there are several models of Core i3, i5 and i7 , and all these versions are not at all equal. In addition, there are two variants for each range of Core processor: one for desktop computers and another for laptops. Do not mix them because each variant for its own characteristics .

how do I know if a processor is better than another?

as I said previously, there are compare processors compared to their number of cores, their frequency, the size of their cache and find out if they have certain technologies like the Turbo Boost and Hyper-Threading.

to begin with, the number of cores. This is the main difference and not least between the Core i3, i5, and i7 processors . More there are hearts and more tasks can be achieved at the same time. The minimum number of heart we can find is two on the Core i3 processors . At present, all Core i3 are the dual-core processors.

However, we can not rely only number of heart or the frequency of a processor to evaluate its performance. In fact, there are a number of factors to be taken into account in order to assess the power of a processor.

for example, a Core processor i5-3570 that for four cores, and 3,40 GHz frequency. A Core i3-3240 is also clocked at 3.40 GHz, can deal with also four threads with HyperThreading technology that does not have the Core i5 and besides, it’s much cheaper. At first glance, it is more interesting to buy the Core rather than the Core i5 i3 . At first sight only! Even if the Core i5-3570 works normally at the same frequency as the Core i3-3240, and even if both can handle the same number of threads, the Core i5 is the Turbo Boost technology . This allows the Core i5 to reach a rate of 3.80 Ghz! As all Core i5 processors have the latest version of this technology – the Turbo Boost 2.0, all can easily outrun a Core i3. In addition to this, it is better to have four ‘real’ hearts (like the Core i5) rather than two hearts + two virtual cores – thanks to HyperThreading (as the Core i3).

to be able to compare more in detail the features of the processors, read the article on the processor Intel Core performance indices.

Intel also offers a guide to help you choose an Intel processor tailored to your needs. It is fairly simplistic but can be useful for the more lazy to be you 😀

If you want to have a clear overview of the differences between the Core i3, i5, and i7 processors , read the article “a processor for each profile. Depending on your needs and your use of the PC, a Core processor will suit you more than another.

a processor for each profile

in General, what you need to remember if you know absolutely nothing about processor: Intel Core i3 < Intel Core i5 < intel Core i7. The Core i7 is the the most powerful processor proposed by Intel, followed by the Core i5 and Core i3. So far nothing complicated! 😀

can we do the same thing on my PC as it for a Core i3, i5 or i7 processor ? No, each processor fits a particular profile. You must first think about what you want to do with your computer, and then choose the processor that corresponds to your user profile. To help you locate and choose the processor , which is similar to your use of the PC, I propose a small comparison between three processors offered by Intel.

Intel Core i3: entry gram

Core i3 corresponds to the entry level, it can be used for basic office tasks, browse the internet, make audio and video calls, make photo editing and HD videos. The integrated graphics processor Intel HD Graphics 530 is not enough to play the recent video games, you need to acquire a dedicated graphics card. However, you can still play games that are not demanding graphics resources.

specifications:

  • dual-core processor : two hearts (+ two virtual cores with HyperThreading)
  • Socket 1151

  • not from Turbo Boost
  • 3 MB L3 cache
  • processor Intel HD Graphics 530 graphics

price a sixth generation i3 Core processor Skylake starts at ~ € 120,00 for a Intel Core i3 6100 .

Intel Core i5: mid range

Core i5 is in the middle range, it is a little bit faster for tasks daily but much more efficient than the Core i3 for video games or video editing. Excellent value, better than the i3 and much cheaper than the i7, is an excellent choice today to turn to Core i5 . Don’t forget to add a GPU (graphics card) dedicated to enjoy latest video games 😉

  • processor Intel HD Graphics 530 graphics

the price of a Core processor sixth generation i5 Skylake starts at ~ € 230.00 for a Intel Core i5 6600 .

Intel Core i7: high-end

Core i7 corresponds to the high end, it offers the best possible performance for playing video games, video editing and use modeling software, animation and 3D rendering. The HD Graphics 530 integrated graphics will let you play video games that do not require extreme graphics performance. Take advantage of the latest recent games, to the usual turn to a GPU.

comparative table of processors Intel Core

here is a very good table comparison of all Intel processors : Core i3, Core i5, Core i7, and Pentium and Celeron. It is realized and constantly updated by CPU Benchmarks , you can also view on this page . The table allows you to compare very easily all the processors. Scores of processors are calculated from PassMark PerformanceTest software .

was where I write these lines, the table was last updated on September 5, 2016.

the last word

with all of this cluster of processor proposed by Intel, it is not easy to navigate! You have nevertheless several tools at your disposal to help you choose your processor . You can either manually compare and precisely through their processors specifications .

is the most effective method, it guarantees you to have the processor that is the closest to your needs. otherwise, you can help system of rating in stars of Intel or from comparison table proposed by CPU Benchmarks to make your choice, if you are not able to compare yourselves processors. That is, you have now all the cards in hand to choose your future processor 🙂

but the crab, I don’t REALLY know what CPU choose!

good very good 😛 I’ll tell you the three Core i3, Core i5 and Core i7 processors to focus on. Simply to choose between one of these three – there according to your budget!
