Core i5-10400F Core i3-12100F Core i5-12400F Ryzen 7 7800X3D Ryzen 7 9800X3D Core i9-14900K Ryzen 9 9950X

By our estimate, Core Ultra 9 285K beats Core Ultra 7 265K by 14%.

Both CPUs use the same socket (LGA1851), so you can swap one for the other on the same board (check BIOS support).

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.
