CPU performance. Table with a simplified representation of the Intel line
Choose the right laptop has become quite difficultdue to the complication of its hardware stuffing itself. If before all the processors were single-core, you could safely choose the laptop with the highest clock frequency.
This or that component can play a decisiverole in performance. For example, if a PC should be able to withstand as much time as possible without recharging, then the processor should also be energy efficient. Often manufacturers voice "screaming" parameters like high memory, "forgetting" to say that the device is kept without recharging for a maximum of 3 hours.
In order not to fall for this (and many others)tricks, it is better to understand a little bit the assortment of modern laptops, than to be disappointed in the purchase in the future. And the simplest task is to study the performance of the processors. The table, which will be presented below, clearly shows the line of Intel processors, their main advantages and disadvantages. However, the advantages and disadvantages of this or that processor will be easier to consider on the "live" example of several popular models, typical representatives of a particular user category.
"Notepad and immortal" Intel Atom
A popular solution for journalists and writers,looking for inspiration outside the walls of the house (and hence, far from sources of recharging) is equipment with an integrated microprocessor Intel Atom. This processor is more common in the architecture of laptops and netbooks and is leading in terms of power consumption due to low requirements for heat sink. So, the model Eee PC X101CH can work for 5 hours at an average workload. When the brightness of the screen is reduced and the software is used to optimize energy consumption, the period increases to 8-9 (!) Hours. The above example is typical, characterizing the energy-efficient performance of processors. A table with detailed data on work without recharging individually for each model is published on the manufacturer's website.
Office and kosynochny battle. Intel Core i3
An excellent find for home and office aremodel notebooks based on Intel Core i3. Such dual-core processors can fully support the execution of several simple tasks at the same time: viewing photos, surfing and undemanding to the hardware stuffing arcade. That's why they are a popular solution in working with office applications at work and a full-fledged multimedia center - at home. The performance of Intel processors for needs not related to the need for processing of capacitive graphics data is usually limited to the i3 series.
Space scales and wars. Intel Core i5 and i7
Fans of Internet battles and 3D games are dedicated to ...
For those who are used to multitasking and work withhigh graphics, the best option is a gaming machine based on one of the processors series i5 or i7. Many can argue, saying that the line of i7 is more efficient, but such a capacious expensive processor does not justify investments. Such a performance of laptop processors is often simply not necessary, since their mobility is not justified: they are very energy-intensive and quickly discharge the laptop. Meanwhile, this is an excellent solution for business and IT sphere due to high performance and, most importantly, mobility of the device with this data.
CPU Performance: A table of the main user characteristics
| Intel® Processor | Benefits | disadvantages |
| Atom | Cheapness, quick start of the device, effective power consumption | Low productivity |
| Core i3 | Relative cheapness, integration with popular applications and old games | Insufficiently high performance for working with productive applications |
| Core i5 | High performance, multitasking, the ability to work with resource-intensive games | Higher price, lower energy efficiency of the device |
| Core i7 | High performance, actualization of the device for several years ahead | High price |
It should be repeated that the technical featuresthis or that device based on the processor of a certain line may differ, but the information popularized by the manufacturer for a normal user looks exactly like this.
