Benchmarks

  • 3D Rendering : Results are from the Cinebench 15 CPU test (the higher the score, the better)

Intel Core i7-8705G – Dell XPS 15 9575

PERFORMANCE : 790.00

Intel Core i7-8550U – Dell Inspiron 5770

PRICE : $998.88

PERFORMANCE : 635.00 (-10.1%)

  • Adobe Photoshop : Results are from our Photoshop benchmark test (the lower the score, the better)

Intel Core i7-8705G – Dell XPS 15 9575

PERFORMANCE : 9.30

Intel Core i7-8550U – Dell Inspiron 5770

PRICE : $998.88

PERFORMANCE : 9.96 (0.5%)

For the purposes of this juxtaposition, we have decided to compare the performance of the two chips found in Dell XPS 15 9575 and Dell Inspiron 5770 respectively. Looking at the charts above, Intel Core i7-8705G shows around 24% better results when it comes to 3D rendering (tested with Cinebench 15). On top of that, it is also 7% faster in the Adobe Photoshop test compared to Intel Core i7-8550U.

Conclusion

Judging by the fact that Intel Core i7-8705G shows better results in 2/2 benchmarks, it would be only fair to crown it as the winner in today’s comparison.
