Blender rendering score
Median score 304 (middle half of runs 301–319) across 20 community runs on Blender 4.x with the HIP backend. That is #87 of 103 graphics cards in our dataset with a score, and #14 of 14 in the Radeon RX 6000 series.
This is a rendering benchmark (samples per minute over the monster, junkshop and classroom scenes), not a gaming benchmark. It says how fast the part renders in Blender's Cycles engine and nothing about frame rates. Source: Blender Open Data, CC0, snapshot 2026-09-06.
