Core i5-12400 vs i7-1280P
Description
Both models i5-12400 and i7-1280P 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 i5-12400 gets a score of 552.6 k points while the i7-1280P gets 468.3 k points.
Summarizing, the i5-12400 is 1.2 times faster than the i7-1280P. To get a proper comparison between both models, take a look to the data shown below.

AVX2 optimized benchmark
The benchmark in mode III (AVX2), like AVX1, is optimized to used 256 bits registers beside the second version of the Advanced Vector Extensions (AVX). The first AVX2 compatible CPU was released in 2013.

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.
