The central processor for a laptop that perfectly combines a high level of performance and energy efficiency is the Intel Core i5-3317U. Although it was released a long time ago by the standards of computer technology - in 2012, but its technical specifications still remain relevant, and it can still run the most demanding transcriptions and the most demanding toys of the latest generation.
Socket
The processor socket, which is designed to install the Intel Core i5-3317U , is the FCBGA 1023. In this case, the socket itself in the classical sense is missing. Essentially, the CPU chip is soldered onto the system board. On the one hand, this reduces the cost of the PC assembly process and reduces its cost. But in the event of a breakdown, repairing such a laptop will be very problematic. But this practice has become generally accepted at the moment, and there is no particular choice among mobile computing systems in this regard.
Chip architecture
The Intel Core i5-3317U belongs to the CPU generation codenamed Ivi Bridge . The characteristics of the semiconductor crystal itself indicate the presence of 2 physical modules, which are converted into 4 information processing and code streams using the Intel NT technology at the level of system software. Like all modern CPUs of this manufacturer, this chip is equipped with a cache of 3 levels with the following values:
The total size of level 1 cache is 128 kb. This will be 64 KB for each computing unit. Additionally, 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 64 Kb module can only be exchanged directly with one specific core.
The total amount of the 2nd level of this memory in this CPU is 512 Kb. That is, 256 Kb is provided for the needs of each core. There is no special specialization in the storage of data or instructions, as in the previous case, at the 2nd level. But a separate module can only interact with its 256 Kb.
Level 3 cache for this processor has a dimension of 3 MB. It is common to all elements of the processor and also, like the 2nd level, does not have much specialization regarding the type of information stored. That is, in its common address space both data and instructions are stored.
The semiconductor chip of the central processor also includes the north bridge of a set of system logic and a memory controller. The latter is aimed at working in tandem with DDR3 modules ( recommended frequencies are 1333 MHz or 1666 MHz) and is dual-channel. The maximum size of addressable RAM is 32 GB.
Thermal conditions, frequency formula, production technology
Intel Core i5-3317U has a very, very modest thermal package at 17 watts. Theoretically, it can function perfectly with a passive cooling system, but most manufacturers equip such PCs with active cooling for greater reliability of the computing system. The maximum temperature for this chip is 105 0 . This processor supports TurboBust technology . As a result, it can dynamically change its clock frequency. Its minimum value in this case is 1.7 GHz, and the maximum is 2.6 GHz. The production technology of this silicon chip meets the standards of 22 nm, and the code name for the process technology is TriGate.
Integrated graphics
The Intel Core i5-3317U processor is equipped with an integrated graphics card. Its model is HD Graphics 4000. Its minimum frequency is 350 MHz and its maximum is 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 in order to unleash the potential of this CPU model.
Summary
The Intel Core i5-3317U has been 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.
