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.
