The Intel Core Ultra 5 235F is the objective winner of this comparison, securing victory in eleven out of sixteen measured specifications. While the Intel Core i5-13400F holds a 14% advantage in thread count, the Intel Core Ultra 5 235F provides a significantly more substantial lead in memory architecture. Specifically, the Intel Core Ultra 5 235F offers an L2 cache that is 111% larger than that of the Intel Core i5-13400F, representing its most impactful technical advantage.

Users prioritizing raw thread capacity for specific multi-threaded workloads should select the Intel Core i5-13400F. Conversely, the Intel Core Ultra 5 235F is the superior choice for those who benefit from a vastly expanded L2 cache and the broader range of technical improvements found across the majority of the measured specifications. Choosing between these two processors depends entirely on whether your specific computing needs favor the higher thread count or the significantly larger cache capacity.
