Core i7-12700H vs i9-12900KF


Description
Both models i7-12700H and i9-12900KF are based on Alder Lake architecture.

Alder Lake is the 12th generation of Intel Core. It uses the 10nm proccess and was the first to introduce a hybrid architecture with Performance cores and Efficiency cores.

Using the multithread performance as a reference, the i7-12700H gets a score of 643.3 k points while the i9-12900KF gets 1219.3 k points.

Summarizing, the i9-12900KF is 1.9 times faster than the i7-12700H. To get a proper comparison between both models, take a look to the data shown below.

Monothread performance graph
Monothread performance graphics gives the performance vs time. They are useful to measure the time it takes to the CPU to reach the maximum performance.

Usually, CPU's performance will be steady during these tests but if it has a slow frequency strategy, the first samples will show a lower score.

Multithread performance graph
Multithread graphs measure the performance against a heavy load during certain time.

If CPU's TDP doesn't limit the frequency and the machine is properly cooled, performance should remain steady vs time. Otherwise, the performance score will oscillate or decrease over time.
