The best way to measure the performance of a CPU is by using real programs. The problem, of course, is to create a methodology that offers precise results. For Photoshop CC we used a script named “Retouch Artist Speed Test”, which applies a series of filters to a standard image and gives the time Photoshop takes to run all of them. The results are given in seconds, so the less, the best.
In this test, the Celeron N3150 was 18% slower than the Pentium J2900 and 16% slower than the Athlon 5150.
