Intel Core i5 is an Intel processor series intended for the x86-64 desktop that addresses the use of the Nehalem microarchitecture. Unlike the Intel Core i7 processor, the Intel Core i5 processor uses a socket called LGA 1156. The Core i7 processor’s Core Nehalem processor. The difference for its Core i7 brother comes from the fact that the i7 generation has a built-in PCI-Express graphics controller, using a communication interface called DMI (Direct Media Interface), which further speeds communication with the chipset and Due to the lack of the SMT, similar to Hyper-Threading of the old Pentium 4.
The first model of the Core i5 a series was released to users on 9 September 2009, called the Core i5 750. The Core i5 750 was the first model of the new generation and features a 2.66 GHz frequency, working with 4 cores ( Quad Core) and having an 8 MB L3 cache. Compared to its brother (Core i7) of the same family, the Core i5 processor has increased its capacity, now supporting DDR3-1333 memories. However at a disadvantage the Core i5 processor can only work in Dual Channel mode while the current Core i7 models can work in Triple Channel mode. Another novelty in the Core i5 series is the fact that the new standard of video controllers will already be introduced in the processor itself, and an intermediate means of communication is unnecessary. With this, the communication between CPU and GPU will be direct through a bus (which is seen as an example of the QPI bus), increasing even more the performance of the computer.
During the launch of the first Core i5 series, Intel announced that the Core i5 processor series will have 3 different core designs, meaning not all Core i5 processor models have the same core. With this, Intel announced the launch of two more cores, which joined the current family, of the core used in the model i5-750, named Lynnfield.
Lynnfield is the name of the first core to be released in the Core i5 generation, and the second core to be released in the Nehalem family, following the launch of the Core i7 generation Bloomfield core. There was introduction of the Lynnfield core in the first model of the i5-750 Core i5 series. This version of the core has an advantage over the Bloomfield core, such as: it is not embedded in the processor itself, it will speed up communication between the processor and the video card, creating a link between CPU-GPU, as well as compatibility with memories of higher frequencies . Its disadvantage has been in preserving the Dual-Channel memory mode and the lack of the Hyper-Threading feature present only in the Lynnfield 8XX series I7 models.
Arrandale will be the second core of the Core i5 series, and will be manufactured in a smooth 32 nm. According to Intel the energy savings will be much higher compared to the current 45 nm smoothness used in the Lynnfield core. The models of this generation already have a graphics controller built into itself. The disadvantage will be in a smaller cache that has gone through the 3MB L3 home. Its release is scheduled for the end of this year [when?] Or early next year.
Clarkdale will be the third core of the Core i5 series, targeting Desktops. These models will be introduced in the i5-6xx series. They will have a slightly larger cache (compared to the Arrandale core), by the home of the 4MB L3 cache. Your advantage, if compared to your other siblings, will be hyper-threading (hyperbolic threads) that will be enabled in these models.
Differences between the models
The Core i5 is a very attractive line of processors from Intel. Some models even deliver superior performance on some Core i7 input. Here, you will know the main models of Haswell architecture and know the differences between them. Check it!
In our selection, there are only models intended for use on the desktop, since notebook processors can not be chosen by the user.
Today, there are 23 variations of Core i5 available for desktops. Although many, there are a few mantillas to know if the processor in question is better than another. Just be aware of the nomenclature:
The higher the model number, the higher it is in the hierarchy. For example, a Core i5 4670 is greater than a 4440. In addition, there are suffixes that differentiate variations of the same model. Are they:
No suffix: default version of each template
Suffix T: variation with low energy consumption
Suffix S: middle ground between performance and consumption
Suffix E: version optimized for plate-welded use, such as all-in-one
Suffix K: ideal version for overclocking;
Suffix R: best graphics card version, the Iris Pro 5200
Here are some of the most interesting models in the i5 line:
Core i5 4670K
Accompanied by the brother 4670, it forms the pair of main models of the line Core i5. The K in the name of any Intel processor means that it allows users to overclock: accelerate the processor via the increase in available power. This feature makes the 4670K ideal for gamers and users who require a lot of CPU.
With four cores in terms of standard speed, the 4670K delivers up to 3.8 GHz. In addition, it has 6 MB of cache, which is a type of internal memory of the processor, used to speed up its operation.
The processor dissipates 84 watts of power. Note that this number does not refer to the 4670K’s power consumption. This value, also known as TDP, refers to the amount of heat that needs to be eliminated in order for it to function properly. Of course, the more heat an electronic component dissipates, the more energy it consumes.
This model also offers a built-in graphics processor, the Intel HD Graphics 4600 which, while not ideal for games and heavy applications, is more than enough to watch high-definition content. In Brazil, the 4760 models are difficult to find and, when they are, prices range from around $ 900 to $ 1000.
Core i5 4670R
If you will not overclock, the best Core i5 available is this. The reason is simple: unlike the rest of the 4670 series, it has a better built-in graphics card. Isis Pro Graphics 5200 performs much better than Intel HD Graphics, and for many people, it is enough for games and entertainment.
However, in this version the CPU performance is somewhat lower: 37 GHz maximum speed and a cache of 4 MB. With less speed, the processor dissipates less energy: 65 watts.
Core i5 4460
If you want to set up a PC for simpler home use, such as surfing the internet, casually watching movies and series, there is no need to invest heavily in a processor.
To meet these needs well, the 4460 is an excellent choice. Priced at $ 800, the model delivers 3.4 GHz speed and 6 MB cache, accompanied by the Intel HD Graphics 4600 GPU.
