Core i3-1215U vs i7-1280P


Description
Both models i3-1215U 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 i3-1215U gets a score of 185.6 k points while the i7-1280P gets 468.3 k points.

Summarizing, the i7-1280P is 2.5 times faster than the i3-1215U. To get a proper comparison between both models, take a look to the data shown below.

Non-optimized benchmark
The benchmark in Mode 0 (FPU) measures cpu performance with non-optimized software. It uses the basic µinstructions from the i386 architecture with the i387 floating point unit. This mode is compatible with all CPUs so it's practical to compare very different CPUs

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.
