Recently we published the comparison between two members of the 8th Generation Kaby Lake Refresh – Intel Core i7-8650U and Intel Core i7-8550U. It turned out that these two chips were quite similar in terms of specifications but the former manages to outperform its rival in 3 out of 3 benchmark tests.

This time we’ve decided to put the Intel Core i7-8650U and the Intel Core i5-8250U side by side and see just how much of a difference there is.

Specs overview

Just like Intel Core i7-8550U, Intel Core i5-8250U shares very similar specs with its opponent – the Intel Core i7-8650U. Both chips are part of the Kaby Lake Refresh and are built on the 14nm manufacturing process. They also feature four physical cores and a total of eight threads. In addition, their power draw is estimated at 15W. As for the graphics part, both incorporate the integrated Intel UHD Graphics 620

On the other hand, Intel Core i5-8250U falls behind its rival when it comes to clocks. Its base frequency is just 1.60GHz opposed to 1.90 GHz on the Core i7-8650U. This also applies to the maximum boost frequencies which are 3.40 GHz and 4.20 GHz respectively. Both platforms support dual-channel DDR4 memory although it is up to 2400 MHz in the Core i7-8650U and up to 2133 MHz for its opponent.
