Cinebench R11.5, 64bit (Single-Core)

Cinebench 11.5 is based on the Cinema 4D Suite, a software that is popular to generate forms and other stuff in 3D. The single-core test only uses one CPU core, the amount of cores or hyperthreading ability doesn't count.

Passmark CPU Mark

Some of the CPUs listed below have been benchmarked by CPU-monkey. However the majority of CPUs have not been tested and the results have been estimated by a CPU-monkey’s secret proprietary formula. As such they do not accurately reflect the actual Passmark CPU mark values and are not endorsed by PassMark Software Pty Ltd.
