Core i3 processors connect to the chipset via the DMI bus
They are positioned as processors of initial and intermediate level of price and performance. In the new model range are designed to replace the outdated Core 2 Duo on the architecture of Intel Core 2. They have built-in graphics processor and built-in memory controller. Core i3 processors connect to the chipset via the DMI bus, DMI 2.0 or DMI 3.0. Support the instructions - MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, AVX, AVX2. They support technologies - Enhanced Intel SpeedStep Technology (EIST), Intel 64, XD bit (implementation of NX bit technology), Intel VT-x, Smart-Cache, and Hyper-threading technology, which makes the operating system recognize this dual-core processor as four core. Do not support the technology of Turbo Boost (automatic overclocking the processor under load).
Generations of Core i3 Processors
The first Core i3 processors were released on January 7, 2010. The first representatives of the Core i3 family based on the Clarkdale core of the Nehalem microarchitecture had an integrated GPU and two processor cores. Processors Core i3-3xxM based on the core Arrandale were mobile versions of processors Clarkdale for desktop systems.
The second generation of Core i3 processors was introduced on February 20, 2011. The processors were based on the Sandy Bridge microarchitecture. Numbering is i3-2xxx.
The release of the third generation of Core i3 based on Ivy Bridge microarchitecture took place in April 2012. Numbering is i3-3xxx
In September 2013 , the Core i3 processors of the fourth generation Haswell were introduced. Numbering i3-4xxx. Processors Core i3-43xx have an increased volume of L3-cache - 4 MB, Core i3-41xx - 3 MB. In models Core i3-43xx there is a graphics core HD Graphics 4600 with 20 executive devices. The Core i3-41xx uses a graphics engine HD Graphics 4400, featuring 16 executive devices. The new generation Core i3 received full support for the same command systems as the Core i5 and Core i7 series processors.
In October 2017, four-core processors Core i3 of the eighth generation of Coffee Lake were presented with the numbering 8xxxx. They have an unlocked multiplier. In August 2017, the processors passed the test, which showed that in some scenarios they could compete with Core i7 .
Core i3-8350K processor review: when i3 is faster i7
The processors of the Intel Coffee Lake family remain one of the most "hot" topics of this season. This is clearly visible from the current range of retail stores. Although the announcement of Intel's new products took place more than two months ago, on the shelves they are presented somewhat limited, and the prices for existing models due to the deficit are far from the recommended values. But despite the significant shortages, the older Coffee Lake easily fall into the number of bestsellers - just look at the sales level. For example, in the statistics of the largest online store Amazon.com Core i7-8700K confidently takes the first place among the processors among processors more than $ 300.
Given the high interest in this subject, our laboratory conducted a detailed testing of four older models of the family Coffee Lake: those that became the practice of Intel's first mass processors with six processing cores. You can find out more about the results of tests of such six-core processors in the following reviews:
With the appearance of the Coffee Lake design in the older series of Intel processors, the number of computing cores increased one and a half times, which inevitably and very significantly affected the performance. However, do not forget about the existence of the younger series of Core i3, with which even more serious changes occurred. While until recently only processors with two processing cores were included in it, Core i3 now became full-fledged quad-core, but without the support of Hyper-Threading technology. This means that Intel has increased the power of its inexpensive series even more than the older chips, and such a change clearly deserves a separate study.
At first glance, the new Core i3 looks just fine. By basic characteristics, they are very similar to the Core i5 of the Kaby Lake era, but they have a price below $ 170 (in theory), which is traditionally typical for the Core i3 series. However, in practice the situation is somewhat different, and the older Core i3-8350K is currently selling 10-15 percent more expensive than the older Core i3-7350K of the previous generation. The result is that, contrary to the original design, price parallels have to be made between the Intel Core i3-8350K and Core i5-7400 quad-core processors, but even with this positioning, the new Core i3 looks more interesting.
That is why we decided to devote our next review to the Core i3-8350K processor, which can become both an excellent basis for a relatively inexpensive system and an appropriate solution for budget-minded enthusiasts who are not ready to pay over 200 USD for open overclocker functions.
However, to draw any serious conclusions about the Core i3-8350K without a detailed investigation would not be very correct. For example, the previous processor of this kind, Core i3-7350K, has not become a popular model, despite the moderate price and overclocking possibilities. The new Core i3-8350K offers a much more advantageous combination of performance and price, but one can also doubt its unequivocal superiority in its price category. The fact is that the processors with six processing cores cost only 10-20 dollars more, and the Core i5-8400 or Ryzen 5 1600 can be more profitable alternatives to the Core i3-8350K. To understand how it really is, we decided in this review.
