[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.

Today we are comparing the Intel Core i5-1240P against the Core i5-1235U.

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.

Results are from the Cinebench R23 CPU test (the higher the score, the better)

Results are from our Photoshop benchmark test (the lower the score, the better)


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.

Results are from the 3DMark: Time Spy (Graphics) benchmark (higher the score, the better)

Results are from the 3DMark: Fire Strike (Graphics) benchmark (higher the score, the better)

Results are from the 3DMark: Wild Life benchmark (higher the score, the better)

Results are from the Unigine Superposition benchmark (higher the score, the better)

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.
