What's the difference between core i3 and i5 and i7
By Ethan Thong 2019-12-28 2611 958
Core i3 is a dual-core processor based on
Intel core i5 core thread 4
Intel core i3 core thread number 2 core 4 thread number secondary cache 2*256KB tertiary cache 4M TDP 65W
The biggest difference between them is that I5 supports Rui frequency, I3 does not, I3 only has dual cores, while I5 has dual cores and 4 cores.
With the development of CPU technology, new products are changing with each passing day. At present, Intel has mainly adopted the second generation i3i5i7 CPU with Sandy Bridge core.
The CPU of the first generation of
First of all, it is recommended that you distinguish between the

I3 dual-core analog quad-core (that is, quad-threaded) no Rui-frequency;
I5 dual-core analog quad-core (that is, quad-thread) has the same technical specifications as i3 except Rui-frequency technology;
I7 quad-core analog eight-core (i.e.
I3 i5 is smaller than that of i5i7.

Core i5 is a quad-core processor based on the Nehalem architecture, using integrated memory controller, three-level cache mode, L3 up 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 uses mature DMI (Direct Media Interface), instead of QPI, and only supports dual-channel DDR3 memory. Structurally, it uses the LGA1156 interface, and Core i7 uses LGA1366. I5 has Rui frequency technology, which can
Core i3 can be seen as a further stripped-down (or castrated) version of Core i5, and there will be a 32nm process version (R & D code Clarkdale, based on
I3 is the integration of GPU (graphics processing unit), that is, Core i3 will be packaged by two cores of CPU+GPU. Due to the limited performance of the integrated GPU, users can add graphics cards if they want to get better 3D performance. It is worth noting that even the production process of the core part of the Clarkdale, display will still be 45nm. The biggest difference between i3 and i5 is that i3 does not have
What is Turbo technology?
When a running program is started, the processor will automatically accelerate to the appropriate frequency, and the original running speed will be increased by 10% 20%. To ensure that the program runs smoothly; when dealing with complex applications, the processor can automatically increase the running frequency to speed up, and easily carry out multi-task processing that requires higher performance;
When switching work tasks, if only memory and hard disk are doing the main work, the processor will immediately be in a power-saving state. This not only ensures the efficient use of energy, but also greatly improves the speed of the program. Increase performance by up to 20%
The second generation core

The moment of history was once again created by INTEL
1, using the new 32nm Sandy Bridge micro-architecture, lower power consumption and stronger performance.
2, built-in high-performance GPU (core graphics card),
3, Rui frequency acceleration technology 2.0, smarter and more efficient.
4, introduce a new ring architecture, resulting in higher bandwidth and lower latency.
5, brand-new AVX, AES instruction set, strengthen
The second generation of intelligent core family is still composed of three major brands: Core i3, Core i5 and Core i7. Intel divides CPU into three major
