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 Core 2 Quad Q8300 was 22% slower than the Core i3-4150, 39% faster than the Pentium N3700, and 38% faster than the Athlon 5150.
