The difference between core i3 and i5 and i7, what is the second generation of Core i3 i5 i7

What's the difference between core i3 and i5 and i7? First, let's focus on the difference between i3 and i5:

Core Core i3 i5 i7 pin Difference

What is the difference between the core i3 and i5, the core i3 and i5 which is good?

The core i3 can be viewed as a further compact version of the Core i5, which will have a 32nm process version (R/D Clarkdale, based on Westmere architecture). The biggest feature of the core i3 is the integration of the GPU (graphics processor), which means that the core i3 will be encapsulated by the CPU+GPU two cores. Because of the limited performance of the integrated GPU, users want to get better 3D performance and can be added to the graphics card. It is worth noting that even if the Clarkdale, the production process of showing the core part will still be 45nm.

Core i3 is a Nehalem architecture based dual-core processor, it still uses the integrated memory controller, level three cache mode, L3 to 8MB, support turbo Boost technology, such as new processors.

In the end, the most important

Intel Core i5 kernel thread number 4 Core 4 threads two cache 4*256kb three cache 8M TDP 95W

Intel Core i3 kernel thread number 2 Core 4 threads two cache 2*256kb three cache 4M TDP 65W

Their biggest difference is that I5 supports the core frequency, I3 does not support, I3 only dual core, and I5 have two cores and 4 cores. As for the core i3 and i5 which good, you weigh.

With the development of CPU technology, new products are also changing, this is not, Intel has now been the main push using the sandy Bridge core second-generation I3 I5 I7 CPU. So it is necessary to once again to the core i3 i5 i7 The difference between the breakdown of why my computer is very card.

The first generation of I3 I5 I7 CPU was the beginning of the 2010 Intel launched a new 32-nanometer core I3/I5/I7 processor, the performance of the PC has taken a leap forward-smaller size, better performance, more intelligent performance and lower power consumption. These three new core I3/I5/I7 processors, what are the characteristics of what different experience, and how they are suitable for users?

First of all, the editors recommend that you distinguish whether the CPU is a portable I3 I5 CPU or a desktop I3 I5 CPU. The i3 of a desktop is a dual-core four thread, with i5 and four cores. Notebook words i3 i5 are dual-core four threads. i3 i5 difference or in frequency with no core frequency technology, the frequency of words i5 to obviously high has been canceled to the Web page navigation.

　　Notebook PC Mobile Core I3 I5 I7 difference:

I3 dual core analog quad cores (ie four threads) without core frequency;

i5 Dual core simulation of the four cores (ie four threads) except the core frequency technology other technical specifications and i3 the same;

I7 Four nuclear simulation of the eight core (that is, eight threads) high power consumption performance;

The performance gap of i3 i5 is smaller than that of i5 i7.

　　Desktop computer Core i3 i5 i7 Difference

Core i5 is a Nehalem architecture based on the four-core processor, the use of integrated memory controller, level three cache mode, L3 to 8MB, support turbo Boost and other technologies of the new processor. The main difference between it and Core i7 (Bloomfield) is that the bus does not use QPI, is a mature DMI (Direct Media Interface), and only supports dual-channel DDR3 memory. Structurally it uses the LGA1156 interface, and the Core i7 is LGA1366. i5 has the core frequency technology, can under certain circumstances overclocking.

The core i3 can be viewed as a further compact version (or castration) of the Core i5, and will have a 32nm process version (R-Clarkdale, based on Westmere architecture). Core

The biggest feature of i3 is the integration of the GPU (graphics processor), which means that the core i3 will be encapsulated by the CPU+GPU two cores. Because of the limited performance of the integrated GPU, users want to get better 3D performance and can be added to the graphics card. It is worth noting that even if the Clarkdale, the production process of showing the core part will still be 45nm. I3 i5 The biggest difference is that i3 does not have the core frequency technology.

Here's a look at a group of desktop DIY assembled computer Core i3 i5 i7 processor performance and parameter diagrams

　　about what is the core frequency technology?

When you start a running program, the processor automatically accelerates to the right frequency, and the original speed increases 10%~20%

In order to ensure the smooth operation of the program, when dealing with complex applications, the processor can automatically improve the operating frequency to speed up, easy to perform more performance requirements of multitasking; When working on a task switch, if only memory and hard disk in the main work, the processor will be in power-saving state immediately. This not only ensures the efficient use of energy, but also greatly improve the speed of the program. By intelligently accelerating the processor speed to maximize performance based on application requirements, up to 20% uptime for high load tasks for optimal performance.

　　Here's a simple introduction to what is the second Daicouri Core i3 i5 i7 technology processor

The moment of history is once again created by Intel! In June 2010, Intel released its revolutionary processor, the second generation of core i3/i5/i7. Second generation Core

I3/i5/i7 is subordinate to the second generation of smart core family, all based on the new Sandy Bridge microarchitecture, compared to the first generation of products mainly bring five important innovation:

1, the adoption of a new 32nm of Sandy Bridge micro-architecture, lower power consumption, stronger performance.

2, built-in high-performance GPU (core graphics), Video coding, graphics performance is stronger.

3, Rui-frequency Acceleration Technology 2.0, more intelligent, more efficient.

4, the introduction of a new ring architecture, resulting in higher bandwidth and lower latency.

5, the new AVX, AES instruction set, enhance the floating-point operation and encryption and decryption operations.

　　The following is a set of second generation core I3/I5/I7 performance and parameter tables for your reference

Intel second-generation Core i3 i5 i7 Difference

The second generation of smart core family is still composed of core i3, Core i5 and Core i7 three major brands, Intel according to the core number, kernel frequency, three level cache and other basic parameters and hyper-threading, Rui-frequency acceleration and other key technologies to divide the CPU into three major brands. i3 i5 difference in performance difference is still not I5 I7 large. For ordinary users, the choice of I3 2100 is undoubtedly the most cost-effective one of the CPU, the current I3 2100 of the price of about 800 yuan up and down, the price is very close to 530, but a lot of performance, replace the first generation of Core i3 intention is very obvious, so core i3 530 become now gradually a snub product.
