A processor of a higher class will have higher clock speed, more number of cores, and better performance. The greater number of cores indicates that the speed of data processing is much faster. The number of cores refers to the multitasking capability. A higher clock speed gives higher processing capability and faster calculations. The clock speed (in GHz) refers to the number of processing cycles that a CPU can conduct per second. The most obvious difference between Core™ i3, i5, i7, and i9 is the clock speed, number of cores, and number of threads. For users such as e-sports player and creator, they would need Core™ i7 or Core™ i9 for their laptops to meet the requirements. Core™ i3 is the entry level and is suitable for multitasking word processing. Intel's flagship Core™ i9 gives the highest performance. The high-frequency Core™ H family has 4 “Brand Modifier”, i3, i5, i7, and i9, depending on the features and the performance.

We can further look into the code and divide it into 4 parts. In general, the greater digit represents the better performance. It's common to see a lot of numbers and letters coming after Core™ H, such as i7-10XXXH. Intel Core™ H series processor is the most frequently used intermediate to high-end processor in the laptop.
