FPSVersusCore i5-10400 vs Core i5-9600K
Performance score
Core i5-10400 and Core i5-9600K are almost equally fast (under 3% apart) — choose by price, socket and platform.
Different sockets (LGA1200 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.
Median of real test runs on users' computers. It does not show FPS in games. Data updated: 31.10.2026.
