Processor for Intel Core i5-3317U notebook: perfect balance of performance and energy efficiency

The central processor for the laptop, which perfectly combines a high level of performance and energy efficiency, is the Intel Core i5-3317U. Although it was released quite a while agothe standards of computer technology - in 2012, but its technical specifications are still relevant, and it can still run the most resource-intensive transcriptions and the most demanding toys of the latest generation.

Socket

The processor socket, which is designed to install Intel Core i5-3317U - this FCBGA 1023. In this case itself is a socket in the classicunderstanding is missing. Essentially, the CPU chip is decoupled from the system board. On the one hand, it reduces the cost of building the PC and reduces its cost. But in the event of a breakdown, it will be very difficult to repair such a laptop. But this practice has now become generally accepted, and there is no particular choice among mobile computing systems in this regard.

Architecture of the chip

To a generation of CPU under the code name Ivi Bridge refers to the Intel Core i5-3317U. The characteristics of the semiconductor crystal itself indicate the presence of two physical modules that, with the help of Intel's proprietary technology, are transformed into 4 information and code streams at the system software level. Like all modern CPUs of this manufacturer, this chip is equipped with a cache of 3 levels with the following values:

• The total cache size of the 1st level is 128 kb. It will be 64 KB per each computational unit. In addition, it should be noted that these 64 KB are divided into 2 equal parts. One of these parts specializes in data storage, and the second - instructions. A specific module of 64 KB can only be exchanged with one specific kernel.

• The total volume of the second level of this memory for thisCPU - 512 KB. That is, for each core needs 256 kb. Special specialization for the storage of data or instructions, as in the previous case, is not at the 2nd level. But a single module can only interact with its 256 KB.

• The cache of the 3rd level in this processor hasthe dimension is 3 MB. It is common for all the elements of the processor and, like the 2 nd level, it does not have a special specialty regarding the type of stored information. That is, in its general address space, both data and instructions are stored.

The composition of the semiconductor chip of the central processor also includes the north bridge of the set of system logic and the controller of operative memory. The latter is aimed at working in tandem with modules DDR3 (the recommended frequencies are 1333 MHz or 1666 MHz) and is two-channel. The maximum addressable memory size is 32 GB.

Thermal regime, frequency formula, production technology

Intel Core i5-3317U has a very, verya modest heat package at 17 watts. Theoretically, it can function perfectly with a passive cooling system, but most manufacturers for more reliable operation of the computer system complete these PCs with active cooling. The maximum temperature for this chip is 105 ⁰C. This processor supports technology TurboBust. As a result, he can dynamically change hisclock speed. Its minimum value in this case is 1.7 GHz, and the maximum is 2.6 GHz. The technology of production of this silicon chip corresponds to the norms of 22 nm, and the code name of the technical process - TriGate.

Integrated graphics

The Intel Core i5-3317U is equipped with an integrated graphics card. Her model - HD Graphics 4000. Its minimum frequency is 350 MHz, and the maximum- 1.05 GHz. Its capabilities are quite enough to solve most of the simplest tasks, and to run more serious applications such a PC needs to be equipped with discrete graphics. This is a prerequisite to unlock the potential of this CPU model.

Outcomes

Intel Core i5-3317U It was widely used in mid-range laptops. The level of its performance is still sufficient and allows you to solve most problems. At the same time, the energy efficiency of this semiconductor solution is at an acceptable level.
