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.
Verdict
AMD Ryzen 9 7900X3D
9.2 / 10 Expert Rating
The AMD Ryzen 9 7900X3D is one of the best gaming CPUs available, its huge L3 cache translating directly into higher in-game frame rates.
