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.
Check out our Top Laptop CPU Ranking to see how the two models stack against others.
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.
Results are from the Cinebench 15 CPU test (the higher the score, the better)
Results are from the Fritz chess benchmark (the higher the score, the better)
For the purposes of this comparison, we have chosen to compare the performance of the two chips found in Microsoft Surface Book 2 (15.0″) and ASUS ZenBook Flip 14 UX461 respectively. Judging by the charts above, the results in our 3D rendering (tested with Cinebench 15) are really close – Intel Core i7-8650U manages to outperform its rival by just around 1%. However, the difference in numbers is more notable in the other two tests. Intel Core i7-8650U scores a 24% better result in the Adobe Photoshop test and surpasses its opponent by 10% in our raw synthetic benchmarks (tested with Fritz).
To sum things up, we can undoubtedly pronounce Intel Core i7-8650U as the winner in our comparison given the results it scored in our benchmark tests.
