Benchmarks

Measured results, not specifications. Percentages are the gap to the leading product in each test.

Blender Cycles (CPU)

Blender 4.5, Blender Open Data (CC0). Median of monster + junkshop + classroom, combined samples/min.

Blender renders 3D scenes by tracing light through them, which loads every core at once. The score measures sustained multi-core throughput, so a chip that wins here can still lose at gaming, where one or two fast cores matter more. Figures come from Blender's Open Data project, which places no restriction on reuse, and we publish the median of every submission for that chip on the same Blender version.
