FPSVersusRadeon RX 6600 vs Radeon RX 7700S
Performance score
Radeon RX 6600 and Radeon RX 7700S are almost equally fast (under 3% apart) — choose by price, socket and platform.
The score is our own estimate from the specs (core count, clock, architecture), not FPS from benchmarks. 100 = the fastest card 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.
