[Comparison] Intel Core i5-1240P vs Core i5-1235U – Both can work fine for you, depending on what you do
Today we have a very interesting comparison between two Alder Lake Core i5 processors, one from the P-series and one from the U-series. How much difference is there, and can the extra TDP be of help to the bigger chip? Keep in mind that the Core i5-1240P also has two extra performance cores, which will be of great help when it’s time for benchmarks.
Here is our Top Laptop CPU Ranking, which has the best laptop CPUs in a list, based on performance.

CPU benchmarks
While the Core i5-1240P shows great improvements in 3D Rendering, scoring 33% higher, the laptops are very close in Photoshop, finishing the benchmark at essentially the same time.
Resultaten är från Cinebench R23 CPU-testet (ju högre poäng, desto bättre)
Resultaten är från vårt Photoshop-jämförelsetest (ju lägre poäng, desto bättre).
GPU benchmarks
While the laptops share the same iGPU, the one inside the P-series processor runs at a higher power limit, due to the CPU having a higher power limit itself. The iGPU inside the Core i5-1240P scores 9% higher in 3DMark Fire Strike and Unigine Superposition.
Resultaten är från 3DMark: Time Spy (Graphics) benchmark (ju högre poäng desto bättre)
Resultaten är från 3DMark: Fire Strike (Graphics) benchmark (högre poäng, desto bättre)
Resultaten är från 3DMark: Wild Life benchmark (ju högre poäng desto bättre)
Resultaten är från Unigine Superposition benchmark (ju högre poäng desto bättre).

Conclusion
The two processors perform well, with the Core i5-1240P being the obvious choice between the two if your work mainly consists of 3D Rendering. However, the CPUs are dead even in Photoshop, so you’ll be fine with both, while the U-series CPU should supposedly deliver longer battery life.
