Blender complete benchmark

Too few submissions · No representative score

Run count: 2

Too few submissions · Individual results onlyn = 2

4.3.0 · monster + junkshop + classroom · CPU · Linux · Ubuntu · 24.04 · 1P · 24 cores · 48 threads

Counts represent submissions; the number of independent systems is unknown. Stock or overclocked status, RAM and power settings are also unknown.

Measurement scope and interpretation

Sample thresholds are an initial display policy, not a guarantee of statistical confidence. P95 is not a theoretical limit. OS submission shares do not represent user market share.
