FPSVersusCore i5-8400 vs Core i5-8500
Performance score
Core i5-8500 is 3% faster than Core i5-8400 by our estimate.
Both CPUs use the same socket (LGA1151), 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.
Median of real test runs on users' computers. It does not show FPS in games. Data updated: 31.10.2026.
