Here we are back again, putting another CPU against the Core i3-1215U. The challenger for today is the Core i5-1135G7, which arrives with a higher power limit, fewer cores, and the same number of threads. However, its base clock speed is much higher, which will allow for more performance in the long run, and less fluctuation when it comes to thermals.

Today we are comparing the Intel Core i3-1215U against the Core i5-1135G7.

Conclusion

Similar to the Ryzen 3 5300U, the Core i5-1135G7 manages to outclass the Core i3-1215U in most CPU-intensive tasks, while the iGPU on the inside also manages to keep up and even outperform the Alder Lake offering in most use cases. As we can see, Alder Lake isn’t that unbeatable, especially in the low-end, where older chips can still be relevant in certain areas.
