Which to select

It is time to pick the winner. What is the difference between Intel Core i7-1255U vs Intel Core i7-11800H? What CPU is more powerful? It is quite easy to determine – look at comparison table. The processor with more cores/ threads and also with higher frequency is the absolute winner!

CPU Cores and Base Frequency

Who will win between Intel Core i7-1255U vs  Intel Core i7-11800H. The general performance of a CPU can easily be determined based on the number of its cores and the thread count, as well as the base frequency and Turbo frequency. The more GHz and cores a CPU has, the better. Please note that high technical specs require using a powerful cooling system.
