Many people blindly believe that in Intel Core processors, the performance of the i5 is not as good as that of the i7, and the performance of the i7 is not as good as that of the i9. In fact, such a view is incomplete. The correct statement is that among the core processors of the same generation, i5, i7, and i9 performance have improved in turn, and of course, ** has also improved. However, Intel Core processors have been released from the 1st generation in 2006 to the 14th generation, and the CPU performance of different generations has improved sequentially, so how can we correctly evaluate and purchase i5, i7, and i9?
1. Intel Core processor naming method
Usually the brand comes first, followed by the processor family, the processor number (which contains the processor's family and SKU number), and in some cases, the product line suffix. As shown in the figure below:
The processor number contains the generation. The number in the number of early Intel Core processors is 4 digits, such as "i7 920", then the first digit in the number is 9, indicating the 9th generation product. At present, 14 generations of products have been launched, and most of the popular products in the market are 13th generation products, as shown in the figure above, the number in the processor number is 5 digits, and the first two digits represent the generation.
2. Performance gaps between different generations of i5, i7, and i9
CPU performance is primarily based on the number of cores, maximum turbo frequency, and size of the support cache. The larger the generation value, the larger the number of cores the CPU contains, the higher the maximum turbo frequency, and the higher the number of caches supported. Below we compare the official data of "12th Gen Intel Core i9 Processor" vs "13th Gen Intel Core i9 Processor".
As you can see from the graph above, the 12th Gen Intel Core i9 processor has 16 cores and a maximum turbo frequency of 510GHz with a maximum cache of 30MB.
The 13th Gen Intel Core i9 processor has 24 cores and a maximum turbo frequency of 56GHz with a maximum cache of 36MB.
It can be seen that the performance gap between different generations of i5, i7, and i9 is still quite large.
3. Purchase suggestions
At present, Intel Core processors are in full bloom in the 13th generation of applications, and the 14th generation has begun to be used. Major IT manufacturers have announced the use of Intel Core 14th generation processors in the new product release in 2024, and the new product has just been launched** will inevitably be higher, so it is recommended to buy the 13th generation Core product at present.
