i3 and i5 and i7 are mainly used in devices such as personal computers and laptops. There are many differences between these processors, including performance, power consumption and price.

Many users may know them as Intel Core cpu processors. i3, i5, and i7 processors have become household names since Intel launched the Core series of processors, which is a popular way of naming commodities based on their level of positioning, i.e., the larger the number, the more expensive and better the performance of the corresponding product.

One, the performance is different

i3 performance is weaker than i5, i3cpu is i5 lite, since it is i5 lite, the performance is certainly not as strong as i5, at present, basically used for the use of low-end computers. The i7 is basically used in high-end computers, performance is stronger than the i3 and i5, but only in the same generation of cpu comparison, cross-generation is generally not comparable! For example, 12 generations of i3 is stronger than 8 generations of i7.

Two, power consumption is not the same

For example, the latest 13 generation processor power i7 ≥ i5 > i3; Core i3-13100 thermal design power consumption (TDP) 60W; Core i5-13400 thermal design power consumption (TDP) 65W; Core i713700 thermal design power consumption (TDP) 65W.

Three, price is not the same

Three, price is not the same

Price i7>i5>i3, this is also very good to understand, the stronger the performance of the more expensive, the so-called a penny a penny! This comparison is only the same generation of processors above the comparison, across the generation is not good to compare, for example, now 13 generations of i3 - 13100 price than 10 generations - i510400 expensive.

Four, the number of cores is not the same

Currently the latest CPU core number is i7>i5>i3, Core i7-13700 is 16 core 24 thread, Core i5-13400 is 10 core 16 thread, Core i3-13100 is 4 core 8 thread. -13100 is 4 cores and 8 threads.

Fifth, the cache is not the same

We all know that the bigger the cache, the faster the speed, the latest CPU cache number is i7>i5>i3, Core i7-13700 Level 3 cache: 30MB, Core i5-13400 Level 3 cache: 20MB, Core i5-13400 Level 3 cache: 20MB, Core i5-13400 Level 3 cache: 20MB, Core i5-13400 Level 3 cache: 20MB, Core i5-13400 Level 3 cache: 20MB. -13400 L3 cache: 20MB, Core i3 - 13100 L3 cache: 12MB.
