Performance score

Core i5-3570 2012 · 4/4 cores/threads, 77 W
13.58
Core i5-6400 2015 · 4/4 cores/threads, 65 W
13.92 +3%

By our estimate, Core i5-6400 beats Core i5-3570 by 3%.

Different sockets (LGA1155 and LGA1151) — switching between them needs a different motherboard.

The score is our own estimate from the specs (cores, threads, clocks, architecture generation), not a benchmark run. 100 = the fastest CPU in our database.

Real tests

What the test measures

Blender is a popular free 3D graphics program. The test makes the device render three ready-made 3D scenes (light, shadows, reflections) and counts how many render passes it finishes per minute. The higher the number, the faster the device handles heavy work: 3D, video editing, photo processing. On a CPU the test loads all cores at once, so it shows the chip's full power; on a graphics card it shows its compute strength.
