Intel has added eight new processors to its lineup, it's a mix of two desktop processors and six mobile processors, some based on the Skylake architecture while others are based on Broadwell. The two desktop processors have a "P" suffix, which indicates these models lack integrated graphics, and the new mobile Core i5/i7 parts have a "DU" suffix. The meaning of the "DU" suffix is unknown.
Mobile Core i5-5200DU, i5-6198DU, Core i7-5500DU and i7-6498DU CPUs have the same number of cores, operating frequency and the size of L3 cache as Core i5-5200U, i5-6200U, i7-5500U and i7-6500U respectively. The official prices of "DU" and "U" processors are identical: $281 for mobile Core i5s and $393 for mobile Core i7s. At this time, we do not have information on what feature is associated with the letter "D" in the model number. For specifications of mobile processor please see further below.
