Intel Core i3
Intel released the Core i series in 2008, which replaced the Core 2 processors. The new series is basically divided into three areas, the Core i3, Core i5 and Core i7 processors. However, this does not mean that e.g. a Core i7 processor must always be faster than a Corei5 CPU. The significant differences are more in some features that may be disabled in lower versions. Since four different generations of this series currently exist, you will find below a list of the respective features. In our assortment you will find both used Core-i3 processors, as well as refurbished computers and notebooks which are already equipped with a Core-i3 CPU.
Composition of the model name
A three-digit number is used for first-generation CPUs. In the following, either a 2, 3 or 4 is prefixed. In addition, letters may appear in the model name. Here is an M for mobile, so the notebook sector, a QM for quad-core mobile, a U, Y, UM or LM for mobile processors with lower TDP and S and T for a lowered TDP value in the desktop area. With a K in name, Intel also features CPUs that can be overclocked.
What differences and advantages do the individual generations contain?
These CPUs contain two physical or four logical cores. In the desktop segment, the maximum clock rate is 3.33 GHz. In the notebook range 2.66 GHz represent the maximum, but the TDP with 37 W is also about half. In general, the CPUs work with DDR3 memory, which can be 8 GB in the notebook and 16 GB in the desktop computer. In addition, a particularly power-saving model is available, which offers long run times, but also a lower performance.
In these processors, clock rates and core numbers are similar to the previous generation. However, the maximum DDR3 memory can be twice as large. The power consumption was also improved here, so that the maximum thermal power loss is 65 W for the desktop models and the highest 17 W for the mobile versions. In addition, the memory access has been accelerated, and the graphics processor has been extended by several functions. Thus, e.g. Some models already have a 3D function.
In this generation, the clock rate was increased to a maximum of 3.5 GHz and also the TDP value could be further reduced. Above all, however, the memory bandwidth has been increased from 21 to 25.6 GB / s. Some models also support ECC memory. Furthermore, minor changes have been made to the graphics core, which makes it possible to connect three screens without using a separate graphics card. As an additional feature, the Intel My Wifi technology finds its way into the processors, which makes it possible, e.g. Connect printers or other Wifi-enabled devices to the notebook.
Based on the Haswell microarchitecture, Core i3 processors have been available since 2013. They offer, in comparison to the predecessor, a better graphics unit and partly also functions such as AES-NI for faster encryption of their own data. These CPUs were developed for the new LGA1150 socket. Thus, they are not compatible with older motherboards and chipsets. In addition, these models have a better integration of USB 3.0, which means more interfaces are available. For the notebook area there are also very economical models, which have a TDP value of only 11.5 W.
Intel Core i3 processors for the desktop PC can still be operated in the LGA 1150 socket. In comparison to its predecessor, Intel has specifically improved the cooling concept, whereby the CPU's CPUs also received various minor improvements. So the potential performance increases a bit. The included GPU also got some customizations and now supports OpenCL 2.0. The Core i3 usually contains two cores, but thanks to hyperthreading, they calculate four threads.
The sixth generation called Skylake also brings a new socket in the desktop PC. The LGA 1151 is therefore essential for operation. At the same time interesting developments in the CPUs, including, for example, Thunderbolt 3 is included. In addition, the graphics unit now also provides three 4K displays without any problems, making it possible to inexpensively realize an office PC with an Intel Core i3, which nevertheless allows modern multi-monitor equipment. In addition, the command extension extensions AVX and AVX2 are included.
With the Kaby Lake architecture, clock speeds are slightly higher than previously possible because Intel has been able to improve the manufacturing process. Added to this are codec acceleration when working with H.265 and VP9 videos, which has a positive impact on multimedia applications. And if you want to upgrade to a seventh-generation Intel Core i3, you do not necessarily need a new motherboard because many manufacturers offer BIOS updates. Another special feature is that with the i3-7350K there is also a processor from the i3 series that can be overclocked with a freely selectable multiplier.
One of the biggest innovations of the Coffee Lake microarchitecture is the increase in the number of physical cores. For example, the Intel Core i3-8100 already has four cores running at 3.6 GHz. Especially with the desktop PC, however, it should be noted that although the socket 1151 is still used, the pin assignment has been changed. For the change, so a new motherboard is needed. In addition, the command-line extensions AVX and AVX2 are already working in the Core i3, which brings additional advantages in the case of corresponding applications.
Why use used Core i3 CPUs?
Thanks to our refurbished CPUs, you have the option of upgrading your existing computer system, but of course you can also use it to equip a new system. The Intel Core-i3 processors are solid entry-level models that provide adequate performance for both office office applications and multimedia services at home.
