In this article, I compare the P-Cores, E-Cores, and LP E-Cores of four Intel processors: the Core Ultra 7 356H, Core Ultra 9 285HX, Core Ultra 9 285H, and Core Ultra 7 255H. The aim is to see how each core type performs in isolation, how well each processor scales when all cores are used, and whether Intel’s LP E-Cores behave like useful compute resources or simply low-power background cores.
